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 battery strings connected in parallel with the battery strings having a plurality of batteries connected in series. The method includes determining, via a controller, one or more operating parameters of the energy storage system. The method also includes determining, via the controller, a maximum current rating of one or more of the battery strings. Another step includes estimating, via the controller, a voltage range for the one or more battery strings as a function of the one or more operating parameters and the maximum current rating. The method also includes dynamically controlling the one or more battery strings based on the voltage range so as to prevent over-current recharge or discharge of the parallel battery strings.
