Claims 1 and 9 now clearly recites the preamble and the body. Therefore, the rejection has been withdrawn.
Rejection of claims 1-8 under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention because of insufficient structure has been withdrawn because of the amendment filed on 3/09/2026. Therefore, the rejection has been withdrawn.
However, the limitation, “a step wherein first information representative…….” is still not clear. Therefore, the rejection has been maintained as set forth below. See the rejection set forth below.
Applicant’s arguments, see remarks page 7-8, filed 3/09/2026, with respect to the rejection(s) of Claim(s) 1-10 under 35 U.S.C. 102 (a) (1) as being anticipated by MATTHEY FANNY et al. (Hereinafter, “Matthey”) in the Patent Application Publication Number WO2020189694A1 (Publication Date 2020-09-24) have been fully considered as follows:
Applicant’s Argument:
Applicant argues on page 7-8 of the remarks, filed on 3/09/2026, regarding the rejection(s) of Claim(s) 1-10 under 35 U.S.C. 102 (a) (1) as being anticipated by MATTHEY FANNY et al. (Hereinafter, “Matthey”) in the Patent Application Publication Number WO2020189694A1 (Publication Date 2020-09-24), that, “In contrast, the Matthey reference has no disclosure of the consideration of information of individual cells of a N cell battery as claimed. The Matthey reference instead discloses the consideration of the battery pack in its globality or as a whole. All of the determinations disclosed in the Matthey reference use one or more models or maps that take into account information of all of the N cells and then averages this information. The Matthey reference does not consider, for its determinations, individual information from each of the N cells.
By considering information from each of the N cells, the method of the device of the application achieves a more precise determination of the total energy available in the battery. In particular, the method of the device of the application makes it possible to take into account the variations in the behavior between cells (which are due to manufacturing disparities but also to their location in the battery pack where thermal and mechanical stresses differ, including cell aging and resistance disparities and other internal disparities which make the battery management apparatus of the Matthey reference imprecise.
The battery management apparatus of the Matthey reference considers the battery pack as a whole. The Matthey reference does not disclose or suggest the method of claim 1 or the device of claim 9 and the Matthey apparatus will not be as precise.
For the above set forth reasons, it is respectfully submitted claim 1-10 currently pending in the application are allowable over the prior art, and a Notice of Allowance is requested (Remarks-Page 8).”
Examiner Response:
Applicant’s arguments, see remarks page 7-8, of the remarks, filed on 3/09/2026, regarding the rejection of Claim(s) 1-10 under 35 U.S.C. 102 (a) (1) as being anticipated by MATTHEY FANNY et al. (Hereinafter, “Matthey”) in the Patent Application Publication Number WO2020189694A1 (Publication Date 2020-09-24), as applied to the Non-Final office Action mailed on 1/15/2026 have been fully considered and is persuasive. Therefore, the rejection of independent claims 1 and 9 has been withdrawn. However, applicant has amended the claim 1, and added the limitation, “a step wherein first information representative of a total energy available in said cellular battery is requested by a processor and a memory of a battery computer and estimated as a function of said current resistance state of health of each of the N cells, current capacity state of health of each of the N cells and current state of charge of each of the N cells, and of a time interval during which said cellular battery is allowed to discharge with a chosen discharge current and at a reference temperature” and similar amendment for claim 9, which necessitates a new ground of rejection. Because claim now recites to determine first information as a function of said current resistance state of health of each of the N cells, current capacity state of health of each of the N cells and current state of charge of each of the N cells, and of a time interval during which said cellular battery is allowed to discharge. Mitsuhashi discloses, “The battery management device 102 performs charge / discharge control of the assembled battery 101 based on the detection results of the current sensor 103, the cell controller 104, the voltage sensor 105, and the temperature sensor 106. At that time, the battery management device 102 calculates various types of battery states as an index indicating the state of the assembled battery 101. The battery state calculated by the battery management device 102 includes, for example, a charged state (SOC), a deteriorated state (SOH), a maximum allowable power, and usable energy; Page 3 Line 37-42)”. Mitsuhashi discloses the parameters for battery but is silent about estimating the values for each cell. Therefore, the rejection of Claim(s) 1-10 under 35 U.S.C. 102 (a) (1) as being anticipated by MATTHEY FANNY et al. (Hereinafter, “Matthey”) in the Patent Application Publication Number WO2020189694A1 (Publication Date 2020-09-24), as applied to the Non-Final office Action mailed on 1/15/2026 has been withdrawn. ABDEL-MONEM et al (Hereinafter, “Abdel”) in the US Patent application Publication Number US 20190288520 A1 is applied to meet at least the amended limitation of claims 1 and 9 and therefore Claims 1 and 9 is now rejected under 35 U.S.C. 103 as being unpatentable over MATTHEY FANNY et al. (Hereinafter, “Matthey”) in the Patent Application Publication Number WO2020189694A1 (Publication Date 2020-09-24) in view of ABDEL-MONEM et al (Hereinafter, “Abdel”) in the US Patent application Publication Number US 20190288520 A1, as set forth below. Dependent claims 2-8 and 10 are rejected under 35 U.S.C. 103 as being unpatentable over MATTHEY FANNY et al. (Hereinafter, “Matthey”) in the Patent Application Publication Number WO2020189694A1 (Publication Date 2020-09-24) in view of ABDEL-MONEM et al (Hereinafter, “Abdel”) in the US Patent application Publication Number US 20190288520 A1, as set forth below. Applicant’s argument is moot in view of newly applied combination of references. See the rejection set forth below. See the rejection set forth below.
For expedite prosecution Applicant is invited to call to discuss the present rejection also if any further clarification needed and to discuss any possible amendment to overcome the references to make the claims allowable.

Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 1-10 are rejected under 35 U.S.C. 103 as being unpatentable over MATTHEY FANNY et al. (Hereinafter, “Matthey”) in the Patent Application Publication Number WO2020189694A1 (Publication Date 2020-09-24) in view of ABDEL-MONEM et al (Hereinafter, “Abdel”) in the US patent Application Publication Number US 20190288520 A1.
Regarding claim 1, Matthey teaches a method for estimating information in relation to a cellular battery [101] of a system (Figure 1) ((battery management devices, battery management methods and power storage Systems; Page 2 Line 2-3; FIG. 1 is a schematic configuration diagram of a power storage system according to an embodiment of the present invention. The power storage system (BESS) 1 shown in FIG. 1 includes an assembled battery 101; Page 3 Line 17-19) comprising N cells suitable for storing electrical energy (The assembled battery 101 is configured by connecting a plurality of rechargeable battery cells in series and parallel; Page 3 Line 23-24),
where N > 1 (Figure 1 shows plurality of cells and therefore N>1), and
each having a current state of charge, a current resistance state of health and a current capacity state of health (The current sensor 103 detects the current flowing through the assembled battery 101 and outputs the detection result to the battery management device 102. The cell controller 104 detects the voltage of each battery cell of the assembled battery 101, and outputs the detection result to the battery management device 102. The voltage sensor 105 detects the voltage (total voltage) of the assembled battery 101 and outputs the detection result to the battery management device 102. The temperature sensor 106 detects the temperature of the assembled battery 101 and outputs the detection result to the battery management device 102. The relay 107 switches the connection state between the power storage system 1 and the inverter 2 according to the control of the host controller 4; Page 3 Line 29-36; each cell in the battery system has current sensor for charge detection, voltage sensor to detect voltage, DCh, SOC and temperature), wherein the method comprises:
a step wherein first information (detection result comprises various types of battery states as an index indicating the state of the assembled battery) representative of a total energy available in said cellular battery is requested by a processor and a memory of a battery computer (FIG. 4 is a diagram showing a functional block of the battery management device 102 related to the usable energy calculation process according to the first embodiment of the present invention. The battery management device 102 of the present embodiment has each functional block of a battery state calculation unit 501, an intermediate voltage calculation unit 502, a remaining capacity calculation unit 503, and a usable energy calculation unit 504. These functional blocks are realized, for example, by executing a predetermined program on a computer; Page 5 Line 6-11) and estimated as a function of said current resistance states of health, current capacity states of health and current states of charge (The battery management device 102 performs charge / discharge control of the assembled battery 101 based on the detection results of the current sensor 103, the cell controller 104, the voltage sensor 105, and the temperature sensor 106. At that time, the battery management device 102 calculates various types of battery states as an index indicating the state of the assembled battery 101. The battery state calculated by the battery management device 102 includes, for example, a charged state (SOC), a deteriorated state (SOH), a maximum allowable power, and usable energy; Page 3 Line 37-42), and of a time interval during which said cellular battery is allowed to discharge with a chosen discharge current and at a reference temperature (The battery management device 102 performs charge / discharge control of the assembled battery 101 based on the detection results of the current sensor 103, the cell controller 104, the voltage sensor 105, and the temperature sensor 106. At that time, the battery management device 102 calculates various types of battery states as an index indicating the state of the assembled battery 101. The battery state calculated by the battery management device 102 includes, for example, a charged state (SOC), a deteriorated state (SOH), a maximum allowable power, and usable energy. By controlling the charge / discharge of the assembled battery 101 using these battery states, the battery management device 102 can safely control the assembled battery 101. As a result, it becomes possible to efficiently control the host system (electric vehicle, hybrid vehicle, etc.) on which the power storage system 1 is mounted; Page 3 Line 37-45; The intermediate voltage calculation unit 502 acquires the charge state SOC and the internal resistance increase amount SOHR from each state value of the assembled battery 101 calculated by the battery state calculation unit 501, and also acquires the battery temperature Tcell from the temperature sensor 106; Page 5 Line 18-20).
Matthey teaches first information is estimated as a function of said current resistance states of health, current capacity states of health and current states of charge.
However, Matthey fails to teach that the first information is estimated as a function of said current resistance states of health of each of the N cells, current capacity states of health of each of the N cells and current states of charge of each of the N cells.
Abdel teaches methods and devices such as modular management systems, methods and devices for monitoring, balancing and/or protecting of a pack of energy storage cells such as battery cells and for estimating a state of a cell or cells such as a State-of-Health (SoH) and/or State-of-Charge (SoC) of a cell or cells (Paragraph [0001] Line 2-7),
wherein the first information is estimated as a function of said current resistance states of health of each of the N cells, current capacity states of health of each of the N cells and current states of charge of each of the N cells (The voltage of each rechargeable energy cell B1 to B4 is individually monitored by a voltage sensing means (4). The voltage sensing means (4) can be provided by an array (4) of voltage sensors, whereby one such sensor can be adapted to measure the voltage of one cell B1 to B4. Alternatively, one sensor may be switched to a cell to be measured (not shown). The voltage sensing means (4) such as the array of voltage sensors can communicate with a central control unit (9) and hence have a means for communicating the voltage measurement results to the central control unit (9). The central control unit (9) has a means for receiving the results of the voltage measurements (e.g. I/O port, or network or bus interface) and also has means for storing these values (i.e. memory) and for processing these values (i.e. processing engine); Paragraph [0117] Line 1-15; For example, a pulsed current such as a square wave or quasi-square wave current can be applied to one or more cells and the response signal voltage recorded. FIG. 19 illustrates a flowchart (300) for this embodiment for estimating the SoH and/or the SoC of a battery cell or cells; Paragraph [0160] Line 1-5; 3) estimating the SoH (State of Health) and/or SoC (State of Charge) of each cell; Paragraph [0006] Line 1; Abdel discloses information as the balancing and/or protecting of a pack of energy storage cells such as battery cells and by estimating a state of a cell or cells such as a State-of-Health (SoH) and/or State-of-Charge (SoC) of a cell or cells). The purpose of doing so is to provide a simple and modular cell balancing system to use for a wide variety of different energy storage cell designs, such as some or all battery technologies in order to perform the balancing in such a way that heat loss is low or lower and/or there is a low or lower energy consumption, to provide an effective test, which can be used quickly, reliably and simply, for example as an OBD health check without using an external source, e.g. for estimating the SoH and/or SoC of energy storage cells or cell packs such as batteries.
It would have obvious to one having ordinary skill in the art before the effective filing date of the claimed invention, to modify Matthey by estimating current resistance states of health of each of the N cells, current capacity states of health of each of the N cells and current states of charge of each of the N cells as disclosed by Abdel, because Abdel teaches to estimate current resistance states of health of each of the N cells, current capacity states of health of each of the N cells and current states of charge of each of the N cells provides a simple and modular cell balancing system to use for a wide variety of different energy storage cell designs, such as some or all battery technologies in order to perform the balancing in such a way that heat loss is low or lower and/or there is a low or lower energy consumption (Paragraph [0025]), provides an effective test, which can be used quickly, reliably and simply, for example as an OBD health check without using an external source, e.g. for estimating the SoH and/or SoC of energy storage cells or cell packs such as batteries (Paragraph [0022]).
Regarding claim 2, Matthey teaches a method,
wherein in said step said first information is further estimated as a function of initial electrical energy storage capacities of each of said cells and initial maximum states of charge of each of said N cells (FIG. 2 is an explanatory diagram of usable energy. In FIG. 2, the broken line indicated by reference numeral 700 represents an SOC-OCV curve showing the relationship between SOC and open circuit voltage (OCV) in each battery cell of the assembled battery 101. Further, the solid line indicated by reference numeral 701 represents a discharge curve when each battery cell of the assembled battery 101 is discharged from the current
SOC to SOC min with a constant discharge current IC0, DCh. In FIG. 2, the current SOC is shown by the broken line 703, and the SOC min is shown by the broken line 705; Page 4 Line 3-8; Figure 2 shows first information as a function of energy storage capacity of individual cell and Figure 2 also shows maximum and minimum SOC).
Regarding claim 3, Matthey teaches a method,
wherein in said step said first information is further estimated as a function of selected theoretical models (Figure 5 and 6 shows the battery model unit 601) respectively representative of equivalent resistances of each of said N cells (The battery state calculation unit 501 acquires the current I, the closed-circuit voltage CCV, and the battery temperature Tcell detected when the assembled battery 101 is charging / discharging from the current sensor 103, the voltage sensor 105, and the temperature sensor 106, respectively. Then, based on this information, each state value of the open circuit voltage OCV, the charging state SOC, the polarization voltage Vp, the charging capacity decrease amount SOHQ, and the internal resistance increase amount SOHR, which represent the current state of the assembled battery 101, is calculated; Page 5 Line 12-17; The intermediate voltage calculation unit 502 acquires the charge state SOC and the internal resistance increase amount SOHR from each state value of the assembled battery 101 calculated by the battery state calculation unit 501, and also acquires the battery temperature Tcell from the temperature sensor 106; Page 5 Line 18-20).
Regarding claim 4, Matthey teaches a method,
wherein in said step said first information is further estimated as a function of the sums of the open-circuit voltages of each of said N cells for state-of-charge values between a maximum state-of-charge and a state-of-charge at the end of said time interval (The battery state calculation unit 501 acquires the current I, the closed-circuit voltage CCV, and the battery temperature Tcell detected when the assembled battery 101 is charging / discharging from the current sensor 103, the voltage sensor 105, and the temperature sensor 106, respectively. Then, based on this information, each state value of the open circuit voltage OCV, the charging state SOC, the polarization voltage Vp, the charging capacity decrease amount SOHQ, and the internal resistance increase amount SOHR, which represent the current state of the assembled battery 101, is calculated; Page 5 Line 12-17; The intermediate voltage calculation unit 502 acquires the charge state SOC and the internal resistance increase amount SOHR from each state value of the assembled battery 101 calculated by the battery state calculation unit 501, and also acquires the battery temperature Tcell from the temperature sensor 106; Page 5 Line 18-20).
Regarding claim 5, Matthey teaches a method,
wherein in said step said time interval is chosen as a function of a minimum cutoff voltage of a cell below which said discharging of the cellular battery with said chosen discharge current is prevented (one limitation is required by the claim ) and/or of a minimum state of charge of a cell below which said discharging of the cellular battery with said chosen discharge current is prevented (In the present embodiment, the usable energy is defined as the total amount of electric energy that can be released by the assembled battery 101 among the electric energy stored in the assembled battery 101. This is until when each battery cell of the assembled battery 101 is discharged with a constant discharge current IC 0, DCh, the SOC of each battery cell becomes SOC min, which is the minimum SOC value allowed for each battery cell. In the meantime, each battery cell corresponds to the total amount of electric energy (Wh) that can be discharged without falling below a predetermined minimum voltage Vmin. The discharge current values IC0 and DCh are preset according to the operation mode and the like of the power storage system 1; Page 3 Line 47-51 & Page 4 Line 1-2).
Regarding claim 6, Matthey teaches a method,
wherein in said step a first theoretical time interval is determined as a function of said minimum cutoff voltage, of current electrical energy storage capacities of each of said cells, of said chosen discharge current, of chosen theoretical models representative respectively of equivalent resistances of each of said N cells, and initial states of charge of each of said N cells (In the present embodiment, the values of the discharge currents ICk and DCh are not preset as in the discharge currents IC0 and DCh in the first embodiment, but are based on the running state of the latest vehicle, and the battery management device 102. Is determined by. That is, the usable energy of the assembled battery 101 in the present embodiment is the minimum that the SOC of each battery cell is allowed for each battery cell when each battery cell of the assembled battery 101 is discharged with the discharge currents ICk and DCh. It corresponds to the total amount of electric energy (Wh) that can be discharged by each battery cell without falling below a predetermined minimum voltage Vmin until the SOC min, which is the SOC value of; Page 8 line 48-52 & Page 9 Line 1-2), and
a second theoretical time interval (past predetermined time as the second theoretical time interval) as a function of said minimum state of charge, said selected discharge current, said current electrical energy storage capacities and said initial states of charge, then said time interval is selected by taking the shorter of said first and second theoretical time intervals (The C rate calculation unit 505 calculates the C rate when the assembled battery 101 is discharged, that is, the ratio of the magnitude of the discharge current to the capacity of the assembled battery 101. For example, the C rate at the time of discharge is calculated by averaging the measured values of the discharge currents obtained from the past predetermined time before to the present and dividing the average value by the rated capacity of the assembled battery 101. The C rate value calculated by the C rate calculation unit 505 is input to the intermediate voltage calculation unit 502a; Page 9 Line 15-20).
Regarding claim 7, Matthey teaches a method,
wherein, in said step, second information representative of an energy state of health of said cellular battery is estimated as a function of said first information and of a useful energy at the beginning-of-life of said cellular battery (In (Equation 9), Remaining Capacity (t) represents the value of the remaining capacity at the current time t. Further, Ahrated represents the rated capacity of the assembled battery 101, that is, the remaining capacity when the assembled battery 101 is fully charged at the start of use; Page 8 Line 1-3).
Regarding claim 8, Matthey teaches a computer program product comprising a set of instructions contained in a memory which, when executed by processing means (FIG. 4 is a diagram showing a functional block of the battery management device 102 related to the usable energy calculation process according to the first embodiment of the present invention. The battery management device 102 of the present embodiment has each functional block of a battery state calculation unit 501, an intermediate voltage calculation unit 502, a remaining capacity calculation unit 503, and a usable energy calculation unit 504. These functional blocks are realized, for example, by executing a predetermined program on a computer; Page 5 Line 6-11),
is suitable for implementing a method for estimating information according to claim 1 (see rejection of claim 1 above) for estimating at least one item of information in relation
to a cellular battery [101] (battery management devices, battery management methods and power storage Systems; Page 2 Line 2-3; FIG. 1 is a schematic configuration diagram of a power storage system according to an embodiment of the present invention. The power storage system (BESS) 1 shown in FIG. 1 includes an assembled battery 101; Page 3 Line 17-19) of a system comprising N cells able to store electrical energy (The assembled battery 101 is configured by connecting a plurality of rechargeable battery cells in series and parallel; Page 3 Line 23-24),
where N > 1 (Figure 1 shows plurality of cells and therefore N>1).
Regarding claim 9, Matthey teaches a device for estimating information of a system (Figure 1) comprising a cellular battery [101] (battery management devices, battery management methods and power storage Systems; Page 2 Line 2-3; FIG. 1 is a schematic configuration diagram of a power storage system according to an embodiment of the present invention. The power storage system (BESS) 1 shown in FIG. 1 includes an assembled battery 101; Page 3 Line 17-19) comprising N cells suitable for storing electrical energy (The assembled battery 101 is configured by connecting a plurality of rechargeable battery cells in series and parallel; Page 3 Line 23-24),

The cell controller 104 detects the voltage of each battery cell of the assembled battery 101, and outputs the detection result to the battery management device 102. The voltage sensor 105 detects the voltage (total voltage) of the assembled battery 101 and outputs the detection result to the battery management device 102. The temperature sensor 106 detects the temperature of the assembled battery 101 and outputs the detection result to the battery management device 102. The relay 107 switches the connection state between the power storage system 1 and the inverter 2 according to the control of the host controller 4; Page 3 Line 29-36; each cell in the battery system has current sensor for charge detection, voltage sensor to detect voltage, DCh, SOC and temperature), wherein the device comprises:
at least one processor and at least one memory (FIG. 4 is a diagram showing a functional block of the battery management device 102 related to the usable energy calculation process according to the first embodiment of the present invention. The battery management device 102 of the present embodiment has each functional block of a battery state calculation unit 501, an intermediate voltage calculation unit 502, a remaining capacity calculation unit 503, and a usable energy calculation unit 504. These functional blocks are realized, for example, by executing a predetermined program on a computer; Page 5 Line 6-11) arranged to perform operations consisting estimating first information (detection result comprises various types of battery states as an index indicating the state of the assembled battery) representative of a total energy available in said cellular battery as a function of said current resistance states of health, current capacity states of health and current states of charge (The battery management device 102 performs charge / discharge control of the assembled battery 101 based on the detection results of the current sensor 103, the cell controller 104, the voltage sensor 105, and the temperature sensor 106. At that time, the battery management device 102 calculates various types of battery states as an index indicating the state of the assembled battery 101. The battery state calculated by the battery management device 102 includes, for example, a charged state (SOC), a deteriorated state (SOH), a maximum allowable power, and usable energy; Page 3 Line 37-42), and of a time interval during which said cellular battery is allowed to discharge with a chosen discharge current and at a reference temperature (The battery management device 102 performs charge / discharge control of the assembled battery 101 based on the detection results of the current sensor 103, the cell controller 104, the voltage sensor 105, and the temperature sensor 106.

The battery state calculated by the battery management device 102 includes, for example, a charged state (SOC), a deteriorated state (SOH), a maximum allowable power, and usable energy. By controlling the charge / discharge of the assembled battery 101 using these battery states, the battery management device 102 can safely control the assembled battery 101. As a result, it becomes possible to efficiently control the host system (electric vehicle, hybrid vehicle, etc.) on which the power storage system 1 is mounted; Page 3 Line 37-45).
Matthey teaches first information is estimated as a function of said current resistance states of health, current capacity states of health and current states of charge.
However, Matthey fails to teach that the first information representative as a function of said current resistance states of health of each of the N cells, current capacity states of health of each of the N cells and current states of charge of each of the N cells.
Abdel teaches methods and devices such as modular management systems, methods and devices for monitoring, balancing and/or protecting of a pack of energy storage cells such as battery cells and for estimating a state of a cell or cells such as a State-of-Health (SoH) and/or State-of-Charge (SoC) of a cell or cells (Paragraph [0001] Line 2-7),
wherein the first information representative as a function of said current resistance states of health of each of the N cells, current capacity states of health of each of the N cells and current states of charge of each of the N cells (The voltage of each rechargeable energy cell B1 to B4 is individually monitored by a voltage sensing means (4). The voltage sensing means (4) can be provided by an array (4) of voltage sensors, whereby one such sensor can be adapted to measure the voltage of one cell B1 to B4. Alternatively, one sensor may be switched to a cell to be measured (not shown). The voltage sensing means (4) such as the array of voltage sensors can communicate with a central control unit (9) and hence have a means for communicating the voltage measurement results to the central control unit (9). The central control unit (9) has a means for receiving the results of the voltage measurements (e.g. I/O port, or network or bus interface) and also has means for storing these values (i.e. memory) and for processing these values (i.e. processing engine); Paragraph [0117] Line 1-15; For example, a pulsed current such as a square wave or quasi-square wave current can be applied to one or more cells and the response signal voltage recorded.

The purpose of doing so is to provide a simple and modular cell balancing system to use for a wide variety of different energy storage cell designs, such as some or all battery technologies in order to perform the balancing in such a way that heat loss is low or lower and/or there is a low or lower energy consumption, to provide an effective test, which can be used quickly, reliably and simply, for example as an OBD health check without using an external source, e.g. for estimating the SoH and/or SoC of energy storage cells or cell packs such as batteries.
It would have obvious to one having ordinary skill in the art before the effective filing date of the claimed invention, to modify Matthey by estimating current resistance states of health of each of the N cells, current capacity states of health of each of the N cells and current states of charge of each of the N cells as disclosed by Abdel, because Abdel teaches to estimate current resistance states of health of each of the N cells, current capacity states of health of each of the N cells and current states of charge of each of the N cells provides a simple and modular cell balancing system to use for a wide variety of different energy storage cell designs, such as some or all battery technologies in order to perform the balancing in such a way that heat loss is low or lower and/or there is a low or lower energy consumption (Paragraph [0025]), provides an effective test, which can be used quickly, reliably and simply, for example as an OBD health check without using an external source, e.g. for estimating the SoH and/or SoC of energy storage cells or cell packs such as batteries (Paragraph [0022]).
Regarding claim 10, Matthey teaches a system comprising a cellular battery [101] (Figure 1) (battery management devices, battery management methods and power storage Systems; Page 2 Line 2-3; FIG. 1 is a schematic configuration diagram of a power storage system according to an embodiment of the present invention. The power storage system (BESS) 1 shown in FIG. 1 includes an assembled battery 101; Page 3 Line 17-19) having N cells suitable for storing electrical energy (The assembled battery 101 is configured by connecting a plurality of rechargeable battery cells in series and parallel; Page 3 Line 23-24),

Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure:
Jin et al. (US 20170225584 A1) discloses, “SYSTEMS AND METHODS FOR STATE OF CHARGE AND CAPACITY ESTIMATION OF A RECHARGEABLE BATTERY- [0002] The present disclosure generally relates to the field of batteries and battery modules. More specifically, the present disclosure relates to estimating states of charge and capacities of a rechargeable battery. [0046] Turning now to FIG. 4, a block diagram of the control module 32 is depicted. The control module 32 may include an SOC module 50 and an SOH module 52. Additionally, the SOC module 50 and the SOH module 52 may represent operations of instructions stored in the memory 36 of the control module 32 that are performed by the processor 34 of the control module 32. For example, the SOC module 50 may represent an operation that estimates the SOC of the energy storage component 14, which is represented by line 54. Additionally, the SOC module 50 may represent an operation that also estimates an SOC error of the SOC estimation, and the SOC error may be represented by the line 56. The SOC error may provide an indication as to how much uncertainty there is in the SOC estimation provided by the SOC module. As the SOC error percentage increases, an accuracy of the SOC estimation may decrease. Because the SOC estimation may be used, for example, as a fuel gauge of the energy storage device 14, accuracy of the SOC estimation may be useful for vehicles to maintain an accurate SOC estimation. Further, the SOH module 52 may provide a second estimate of the SOC of the energy storage component 14, which is represented by line 58, as a percentage of an initial SOC value of the energy storage component 14. Moreover, the SOH module 52 may also include an estimate of the SOC, which is represented by line 60, as a percentage of the SOC estimation, and which may be associated with the SOC estimate provided by the SOH module (line 58). [0047] The SOC estimate provided by the SOC module 50 (line 54) may be obtained through a different method than the SOC estimate provided by the SOH module 52 (line 58). For example, the SOC estimate provided by the SOC module 50 may be obtained by a an integration estimation and the SOC estimate provided by the SOH module may be calculated based on an open circuit voltage (OCV) measurement-However Jin does not disclose a step wherein first information representative of a total energy available in said cellular battery is requested by a processor and a memory of a battery computer and estimated as a function of said current resistance state of health of each of the N cells, current capacity state of health of each of the N cells and current state of charge of each of the N cells, and of a time interval during which said cellular battery is allowed to discharge with a chosen discharge current and at a reference temperature.”
