Management of rechargeable energy storage system having constrained power module

Management of rechargeable energy storage system (RESS) included onboard to a vehicle to provide a high voltage (HV) output to a HV bus and a low voltage (LV) output to a LV bus. The management may include identifying a constrained module of the power modules, determining a current demand for a low voltage (LV) bus of the vehicle, and implementing a compensation strategy for managing the power modules to meet the current demand, including lowering a current output set for the constrained module relative to current outputs set for the unconstrained modules.
