The invention discloses an electric vehicle charging auxiliary power supply device based on an energy storage battery. The device comprises an energy storage and power storage power supply device, theenergy storage and power storage power supply device comprises an energy storage and power storage power supply box, an energy storage battery module and an energy control module, and the energy storage battery module is installed in the energy storage and power storage power supply box. The energy storage battery module is connected with the energy control module, is connected with a power gridthrough a charging circuit and is connected with the power input end of a charging pile through an output circuit, the power grid provides power for charging the energy storage battery module, and theenergy storage battery module supplies the stored power to the charging pile; and the energy control module is used for monitoring the electric quantity of the energy storage battery module and controlling the energy storage battery module to charge and discharge. According to the invention, low-price off-peak electricity can be stored in advance and then supplied to the charging pile for use when the power consumption quota is not in shortage, so that the power distribution pressure of a power grid is greatly reduced, the problem of power distribution capacity increase is solved, and meanwhile, the economic benefit is improved.
本发明公开了一种基于储能电池的电动汽车充电辅助供电装置,其包括储能蓄电供电装置,所述储能蓄电供电装置包括储能蓄电供电箱,储能电池模块和能量控制模块,储能电池模块安装在储能蓄电供电箱的内部,并且储能电池模块连接能量控制模块,同时通过充电线路连接电网以及通过输出线路连接充电桩的电力输入端,电网提供向储能电池模块进行充电的电力,储能电池模块再将储存的电量供应给充电桩,能量控制模块用于监测储能电池模块的电量,并控制储能电池模块进行充电和放电。本发明可以在用电配额不紧张时提前把低价的低谷电进行存储,然后再供给给充电桩使用,进而大大减轻电网的配电压力,解决配电增容的难题,同时提高经济收益。
