Abstract: The present disclosure is directed to a system and method for controlling an energy storage system. The energy storage system includes a plurality of parallel-connected energy storage devices. The method includes determining, by one or more controllers, a limiting energy storage device based at least in part on a current rating for the limiting energy storage device. The method includes determining, by the one or more controllers, an adjusted allowable system current based at least in part on modifying one or more operational parameters of the limiting energy storage device. The method includes determining, by the one or more controllers, a modified operational parameter of the limiting energy storage device to increase the allowable system current of the energy storage system. The method includes controlling the limiting energy storage device based at least in part on the modified operational parameter.

Abstract: In accordance with one aspect of the present technique, a method is disclosed. The method includes identifying a first change in an excitation direction of a group of cells and determining a first set of characteristics of the group of cells corresponding to the first change. The method also includes identifying a second change in the excitation direction of the group of cells and determining a second set of characteristics of the group of cells corresponding to the second change. The second change in the excitation direction is opposite to the first change in the excitation direction. The method further includes determining a number of functional cells from the group of cells based on the first and the second set of characteristics.
