DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 101
35 U.S.C. 101 reads as follows:
Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
Claims 1-15 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. The claims recites calculating a real time maximal energy storage capacity, or obtaining history, comparing the history, the history records include, etcetera. This judicial exception is not integrated into a practical application because the claims are directed to an abstract idea, the claims are directed to obtaining information but do not do anything with the information that is obtained i.e. when a threshold is passed the controller initiates charging of the battery cell or removes the battery cell from operation or draws current from the battery cell. The claims does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because the structure of the circuits and unites is already known within the art as seen by Lee (US 20190305386) below.
Claim Rejections - 35 USC § 102
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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.

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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claim 8 is rejected under 35 U.S.C. 103 as being unpatentable over Lee as applied to claim 1 above, and further in view of Chiyajo (US 2016/0097818).
As to claim 8, Lee is silent to wherein, the groundings of the battery management units connected by the charge-discharge connection, are isolated from each other. Chiyajo disclose a battery pack with a filter circuit ([0013]) wherein a capacitor filter is between each battery terminal and ground ([0010], figure 1). It would have been obvious to one of ordinary skill within the art at the time of the effective filling date of the invitation to use the configuration from Chiyajo within Lee as the arrangement removes noise ([0010], Chiyajo, discussed throughout). Additionally it would have been obvious to one of ordinary skill within the art at the time of the effective filling date of the invention to use more grounds in each battery module to increase safety.
