ACTIVE BATTERY STACK SYSTEM AND METHOD

摘要

An active battery stack DC power conversion and energy storage system and method is disclosed herein. “Active” battery stack shall mean battery modules (e.g., having a least one of or a plurality of energy storage batteries) which can be engaged or disengaged as opposed to “passive” battery stacks in which the battery stack is hardwired and the batteries cannot be separated. Any battery energy storage application can benefit from this active battery management system and method for the flexibility to engage and disengage an individual battery in the battery stack regardless of whether it is charging, discharging or for maintenance purposes.
