  • Abstract Battery power modules (BPMs) with bidirectional buck-boost converters, which are connected in series, are operated interactively but substantially can be controlled individually for either charging or discharging. During the charging process, the battery currents can be scheduled by adjusting the duty-ratios of the associated buck-boost converters. To fully utilize the charger’s capacity, several charging scenarios are proposed according to the state of charges (SOCs) of the batteries under the limitations of the charger’s power and current.
    To demonstrate the feasibility and capability of the charging scenarios, a battery power system formed by 4 serial buck-boost type BPMs is built and tested. A microcontroller is used for estimating the battery SOCs, and then scheduling the battery currents accordingly. Experimental results show the effectiveness of the charging scenarios.
