Abstract:
One embodiment of the present disclosure describes a battery system that includes a battery string with a first and second battery module connected in series; and a battery control system that includes a cell control unit electrically coupled to the first battery module, in which the first cell control unit determines first module level operational parameters related to operation of the first battery module; an integrated string control unit electrically coupled to the second battery module, in which the integrated string control unit determines second module level operational parameters related to operation of the second battery module; determines string level operational parameters related to operation of the battery string based at least in part on the first module level operational parameters and the second module level operational parameters; and controls operation of the battery string based at least in part on the string level operational parameters.
Abstract:
A battery module includes a housing, a plurality of battery cells disposed in the housing, and a printed circuit board (PCB) assembly disposed in the housing. The PCB assembly includes a PCB and a shunt disposed across a first surface of the PCB. A second surface of the shunt directly contacts the first surface of the PCB, and the shunt is electrically coupled between the battery cells and a terminal of the battery module.
