The invention provides a portable battery pack and an electric vehicle charging system, the portable battery pack comprises a battery module and a control module, the portable battery pack is configured in a way that when the portable battery pack is connected to an electric vehicle high-voltage system through a bidirectional direct current voltage converter, the control module selects different control modes according to the state of the electric vehicle. And when the electric vehicle runs and/or is not charged through the charging interface of the electric vehicle, a first control mode is selected to control the bidirectional direct-current voltage converter to utilize the battery module to supply power to a high-voltage system of the electric vehicle. By means of the portable battery pack, inconvenience caused by the fact that a pure electric vehicle needs to be charged through a charging pile can be effectively avoided or reduced, dependence of the pure electric vehicle on charging infrastructures can be reduced, and the use feeling of the electric vehicle is optimized.

    本发明提供一种便携式电池包及电动汽车补电系统,包括:电池模块和控制模块,所述便携式电池包被配置为,通过双向直流电压转换器接入电动汽车高压系统时,所述控制模块根据电动汽车的状态选择不同的控制模式,当所述电动汽车运行和/或不通过自身充电接口充电时,选择第一控制模式以控制所述双向直流电压转换器利用所述电池模块给所述电动汽车高压系统供电。利用本发明的所述便携式电池包,可以有效的免除或者减少纯电动汽车需要通过充电桩进行充电带来的不便,可以降低纯电动汽车对充电基础设施的依赖,优化电动汽车的使用感受。
