CPC H02J 7/0013 (2013.01) [H02J 7/007 (2013.01)] | 21 Claims |
1. A method for managing a plurality of stacks of electrochemical cells, the plurality of stacks being electrically coupled in parallel in a battery, the method comprising:
operating the plurality of stacks to execute a global operating strategy of the battery;
controlling one or more first power converters to change operation of one or more first stacks of the plurality of stacks to execute a first local operating strategy for determining one or more of (a) open circuit voltage of the one or more first stacks and (b) leakage current of the one or more first stacks; and
controlling one or more second power converters to change operation of one or more second stacks of the plurality of stacks to compensate for change in operation of the one or more first stacks caused by executing the first local operating strategy for determining one or more of (a) open circuit voltage of the one or more first stacks and (b) leakage current of the one or more first stacks, and thereby maintain the global operating strategy of the battery while executing the first local operating strategy.
