The invention provides a battery charging system of a pure electric vehicle and a charging control method of the battery charging system so as to realize charging of a battery more reasonably. The battery charging system of the pure electric vehicle is composed of a battery monitoring module, a DC-DC converter, a battery management system, a vehicle control unit, a communication box, a power battery and a remote service provider, and the battery monitoring module, the DC-DC converter, the battery management system, the vehicle control unit and the communication box are in communication connection through a CAN bus. The communication box is in communication connection with a remote service provider in a wireless mode; and the DC-DC converter is respectively connected with the power battery and the storage battery. According to the invention, the state information of the storage battery can be sent and displayed on the mobile phone of the owner in real time, so that the owner can conveniently and remotely know the use condition of the storage battery in real time; the vehicle owner is fed back in time when the charging fails, so that the problem that the vehicle owner urgently needs to use the vehicle due to knowing the risk is solved; and when the performance of the storage battery does not meet the design requirement, a vehicle owner can be timely notified to replace the storage battery.

    本发明提出了一种纯电动汽车蓄电池补电系统及其补电控制方法,以更合理地实现蓄电池的补电。该纯电动汽车蓄电池补电系统由蓄电池监控模块、DC‑DC变换器、电池管理系统、整车控制器、通讯盒、动力电池及远程服务提供商组成,所述蓄电池监控模块、DC‑DC变换器、电池管理系统、整车控制器、通讯盒利用CAN总线通讯连接,通讯盒与远程服务提供商利用无线方式通讯连接;DC‑DC变换器分别与动力电池、蓄电池连接。通过本发明可以将蓄电池的状态信息实时发送并显示于车主的手机上,方便车主远程实时了解蓄电池使用情况;并在补电失败时及时反馈车主,避免车主未知该风险而急需使用车辆的问题;还可以在蓄电池性能不满足设计要求时及时通知车主更换蓄电池。
