The invention provides an electric vehicle energy storage system, which comprises an energy storage module, a voltage conversion module, a first switch module and a control module, wherein the maximumvalue of the output voltage of the energy storage module is greater than the minimum value of the output voltage of a power supply network, the power supply network is connected with the voltage conversion module through the first switch module, the voltage conversion module is also connected with the energy storage module, and the control module is used for controlling the power supply network to charge the energy storage module through the voltage conversion module when the first switch module is closed. According to the electric vehicle energy storage system provided by the invention, whenthe first switch module is closed, the control module charges the energy storage module by controlling the power supply network, so that the cost of arranging a ground charging device is reduced, thecharging mode is simple, and the free switching of the power supply modes on a road section with an overhead line system and a road section without the overhead line system can be realized.

    本发明提供一种电车储能系统,该系统包括:储能模块、电压转换模块、第一开关模块和控制模块;其中:所述储能模块的输出电压的最大值大于供电网的输出电压的最小值,所述供电网通过第一开关模块与所述电压转换模块连接,所述电压转换模块还与所述储能模块连接;所述控制模块用于控制所述供电网在所述第一开关模块闭合时,通过所述电压转换模块向所述储能模块充电。本发明提供的电车储能系统,在第一开关模块闭合时,控制模块通过控制供电网为储能模块充电,不仅减少了设置地面充电装置的成本,使得充电方式更为简单,还可以实现在有接触网路段和无接触网路段进行供电方式的自由切换。
