Regarding claim 20, Kim teaches the method of claim 19. Kim does not teach determining the number of series-connected battery modules by dividing the required voltage by a battery module voltage.
Smith teaches determining the number of series-connected battery modules by dividing the required voltage by a battery module voltage (¶0003: An optimal system design can involve dividing the total desired voltage by the individual battery cell voltage to determine the number of cells).
A person of ordinary skill in the art before the effective filing date of the instant application would have incorporated the method of Smith in calculating the number battery modules to serve the requested voltage of an output in the method of Kim, so that the method would include dividing the requested voltage by the battery voltage to determine the minimum number of batteries needed, so as to maximize the number of unused battery modules so they may be conserved or used for other applications.
