The invention discloses a vehicle power supply device and a battery charging device. Comprising a battery power distribution unit and a whole vehicle power distribution unit. The battery power distribution unit comprises a first battery switching circuit, a battery management module and a battery interface; wherein the battery management module is respectively connected with the battery interface and the whole vehicle power distribution unit; the first battery changing circuit is connected with the battery interface and the whole vehicle power distribution unit. The battery interface is used for being connected with an external battery replacement battery, and the external battery replacement battery supplies power to the whole vehicle power distribution unit through the first battery replacement circuit; and the whole vehicle power distribution unit is used for supplying power to vehicle parts. According to the optimization device for vehicle power supply and battery charging, the problem that due to the fact that the high-voltage power distribution modes in the battery changing box are inconsistent, the battery changing box needs to be managed in a differentiated mode and stored in a partitioned mode in a battery changing station is solved, the structure of a battery changing battery system is optimized, the function of undifferentiated battery changing is achieved, and the cost of the battery changing battery system is reduced.

    本发明公开了一种车辆供电装置及电池充电装置。包括:电池配电单元和整车配电单元;电池配电单元包括第一换电电路、电池管理模块和电池接口;其中,电池管理模块分别与电池接口和整车配电单元连接;第一换电电路分别与电池接口和整车配电单元连接;电池接口用于与外部换电电池连接,外部换电电池通过第一换电电路为整车配电单元供电;整车配电单元,用于对车辆部件供电。本方案提出的车辆供电和电池充电的优化装置,解决了由于换电箱内高压配电方式不一致导致换电站内需要对换电箱进行区别化管理和分区存储的问题,优化了换电电池系统架构,实现了无差别换电的功能,降低了换电电池系统的成本。
