  • Abstract The operation of a battery power bank with buck-boost type battery power modules (BPMs) connected in series and parallel is studied. All BPMs in the power bank are collaboratively to cope with the load requirements under the restraints of a same output current for serial configuration and a same output voltage for parallel configuration. However, the BPMs can substantially be operated individually to schedule the discharged currents from batteries can be in accordance with their state-of-charges (SOCs) and the operating mode of the converters. The operations of BPMs with series and series-parallel configurations are analyzed to derive the current- distribution equations and then to figure out the discharging strategy accordingly. Experimental results demonstrate that excellent performance on discharge equalization can be achieved during the discharging processes. In addition, a fault-tolerance mechanism can be included to isolate those completely exhausted or damaged batteries. These features are helpful to maintenance and management of a battery power system.
