The invention discloses an electric bicycle lithium battery replacement cabinet with an energy storage inversion function, and relates to the technical field of charging. The cabinet comprises an APFC module which is externally connected with a power grid voltage, rectifies the power grid voltage and outputs a DC voltage; a direct-current bus which is used for providing uniform direct-current voltage; a plurality of bidirectional DC-DC modules which are used for converting the fixed direct-current voltage into variable direct-current voltage and charging the lithium battery; an inversion module which is connected with the direct-current bus, converts the direct-current voltage into alternating current and feeds the alternating current back to a power grid; and a main controller which is connected with the APFC module, the bidirectional DC-DC module and the inversion module and controls the working states of the APFC module, the bidirectional DC-DC module and the inversion module. According to the cabinet, unified direct-current voltage is provided; each bidirectional DC-DC module can convert corresponding DC voltage according to different charging requirements of each battery to complete quick charging of the battery; and on the other hand, when the power grid is powered off or is unstable, the inversion module feeds the electric energy stored in the lithium battery back to the power grid.

    本发明公开了一种具有储能逆变功能的电动自行车锂电池换电柜,涉及充电技术领域。包括:APFC模块,外接电网电压,对电网电压进行整流,输出直流电压;直流母线,提供统一的直流电压;若干双向DC‑DC模块,将固定的直流电压变换为可变的直流电压,对锂电池进行充电;逆变模块,与直流母线连接,将所述直流电压转化为交流回馈给电网;主控制器,与APFC模块、双向DC‑DC模块、逆变模块连接,控制APFC模块、双向DC‑DC模块、逆变模块的工作状态。本发明提供统一的直流电压;各双向DC‑DC模块可根据各个电池的不同充电要求,变换相应的直流电压,完成电池的快速充电;另一方面,在电网断电或不稳定的时候,逆变模块将锂电池中存储的电能回馈给电网。
