This thesis studies the operating characteristics of the boost type battery power modules (BPMs) with series and parallel configurations. Under different operating conditions, the BPMs can be operated at the continuous conduction mode (CCM), the discontinuous conduction mode (DCM), or the hybrid mode with a combination of CCM and DCM. The current distribution and balance discharging among BPMs with different configurations are analyzed in detail. Experiments are carried out to demonstrate the analysis results. Finally, a circuit configuration with arrayed BPMs is proposed for adaptable management and maintenance of a battery power system.
