ASAI [title] discloses “A POWER SOURCE APPARATUS WITH ELECTRICAL COMPONENTS DISPOSED IN THE BATTERY BLOCKS” in the annotated figures below where: a sensing assembly (which ASAI refers to as flexible printed circuits) are configured to monitor voltages of the battery cells, wherein PNG media_image18.png 600 794 media_image18.png Greyscale the upper cover includes an upper horizontal plate provided to be horizontal and an upper vertical plate formed perpendicular to the upper horizontal plate and assembled to the cooling block, and wherein the upper horizontal plate includes at least one fixing protrusion that is formed on an inside surface facing toward the receiving space and to which the sensing assembly is fixed. PNG media_image19.png 893 932 media_image19.png Greyscale ASAI [0012] also discloses that “flexible printed circuits can be used as the voltage detection lines for electrical connection between the voltage detection circuit and the electrode terminals of each battery cell. As a result, the labor-intensive wiring operation to connect voltage detection lines such as lead-wires to the battery stack can be eliminated.” It would have been obvious for one of ordinary skill in the art before the effective filing date to have used a sensing assemble in the upper housing to monitor the voltage of the battery in the battery cells taught by ASAI in the battery assembly disclosed by SIVANESASELVAM in order to monitor the voltage of the battery system and eliminating labor intensive wiring. Claim 13 is rejected under 35 U.S.C. 103 as being unpatentable over US 20230170551 A1, SIVANESASELVAM et al. in view of US 20110206948 A1, ASAI et al. as applied to claim 12 above, and further in view of US 20180254536 A1, CHIDESTER et al. Regarding claim 13. SIVANESASELVAM modified by ASAI discloses the battery pack of claim 12 in the annotated figure depicted above. wherein the at least one fixing protrusion includes a plurality of fixing protrusions spaced apart from each other along a periphery of a circuit board included in the sensing assembly, and Modified SIVANESASELVAM does not disclose the plurality of fixing protrusions are coupled to edges of the circuit board by a snap-fit connection. CHIDESTER discloses VEHICLE ENERGY-STORAGE SYSTEMS where “The electrochemical cells may be disposed within various cell holder structures, and may be electrically connected by flexible circuitry. Coupling of various components within the battery pack, strings, and/or modules may be accomplished by pressure fitting, snap fitting, welding such as laser welding, application of adhesive chemicals, or other coupling methods. In some embodiments, battery packs, strings, and/or modules may be liquid cooled.” It would have been obvious to one of ordinary skill in the art before the effective filing date to have used snap fittings in order to secure wiring or a components in a battery module or pack. It is common in the art as of the filing date to use snaps fitting, pressure fitting or some other friction device to fasten components in a casing.
