Abstract
Abstract A battery pack for a battery-powered vehicle is provided in accordance with the present invention. The battery pack for the battery-powered vehicle comprises battery modules coupled in series. The battery modules are configured to provide power to the battery-powered vehicle and each of the battery modules has a state-of-charge. The battery pack also comprises battery control modules (BCMs) that are coupled to the battery modules. Each of the battery modules is coupled to one of the BCMs and each of BCMs is configured to monitor a battery module parameter. Furthermore, the battery pack comprises a battery control interface module (BCIM) coupled to each of the BCMs. The BCIM is configured to receive the battery module parameter from each of the BCMs and independently adjust the state-of-charge of each of the battery modules based on the battery module parameter.
