CONTROLLERS FOR MANAGING A PLURALITY OF STACKS OF ELECTROCHEMICAL CELLS, AND ASSOCIATED METHODS

A method for managing a plurality of stacks of electrochemical cells, where the plurality of stacks are electrically coupled in parallel in a battery. The method includes (a) operating the plurality of stacks to execute a global operating strategy, (b) 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 of operating the one or more first stacks at one of a constant power and a constant current, and (c) 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, and thereby maintain the global operating strategy of the battery while executing the first local operating strategy.
