The power battery charging and discharging management system comprises a modular battery pack; the power battery charging and discharging management device receives a control signal of a charging detection unit or a discharging battery unit on the electric equipment and is linked with the selection circuit, so that the modularized battery pack discharges the electric equipment, or the charging equipment charges the modularized battery pack; and a battery pack series-parallel conversion unit. The power battery charging and discharging management method comprises the steps that in a battery charging mode, whether a charging device provides a first voltage series value or a second voltage series value larger than the first voltage series value in the charging voltage range is judged through a charging detection unit control signal; if the charging voltage value is the first voltage series, selecting a first mode, namely a low-voltage mode, for charging; and if the charging voltage value is greater than the first voltage series value, selecting a second mode, namely a high-voltage mode, for charging. Therefore, the voltage value of the external power supply can be discriminated, and safe charging under low voltage and high voltage can be realized.

    动力电池充放电管理系统,包括:模块化电池包;动力电池充放电管理装置接收用电设备上充电检测单元或放电电池单元控制信号并联动选择电路,来对模块化电池包对用电设备进行放电,或充电设备对模块化电池包进行充电;电池包串并联转换单元。动力电池充放电管理方法,包括:在电池充电模式下,通过充电检测单元控制信号,来判断充电设备是提供充电电压范围是第一电压系列值,还是大于第一电压系列的第二电压系列;若充电电压值是第一电压系列,则选择第一种模式即低压模式进行充电;若充电电压值大于第一电压系列值,则选择第二种模式即高压模式进行充电。据此,能够甄别外部电源电压值的大小,实现了能够在低压、高压下安全充电。
