The invention provides a replaceable vehicle battery pack for rescue charging. The replaceable vehicle battery pack comprises multiple clusters of battery packs; a DC/DC charging and discharging module which realizes input and output of electric energy; a main loop port, which is connected with the DC/DC charging and discharging module in parallel to charge or discharge the multiple clusters of battery packs; a charging gun port, which is connected with the DC/DC charging and discharging module in parallel to charge or discharge the multi-cluster battery pack; and a battery management system which collects the parameter state of each battery pack in the multiple clusters of battery packs and inputs the parameter states to the DC/DC charging and discharging module. According to the replaceable vehicle battery pack, communication and electrical solutions are both placed in the replaceable vehicle battery pack for a vehicle in a battery replacement mode, especially for a large replaceable battery system for a heavy-duty vehicle and engineering machinery, the replaceable vehicle battery pack is adopted for mutual charging, and the charging mode is more flexible, so that mutual charging between vehicles can be achieved, and the electric power supplement of the replaceable vehicle battery pack to another replaceable vehicle battery pack can be directly realized.

    本发明提出了一种用于救援充电的可更换车用电池包,包括多簇电池包;DC/DC充放电模块实现电能的输入和输出;主回路端口与DC/DC充放电模块并联对多簇电池包充电或放电;充电枪端口与DC/DC充放电模块并联,对多簇电池包充电或放电;电池管理系统收集多簇电池包内每个电池包的参数状态,并输入到DC/DC充放电模块。本发明针对换电模式下车辆,特别是用于重载车辆、工程机械的大型可更换电池系统,将通讯和电气解决方案均放置于可更换车用电池包内部,采用可更换车用电池包互相充电,充电方式更加灵活,不仅能够实现车辆之间的互充,还可以直接实现可更换车用电池包对另一可更换车用电池包的电力补充。
