The invention provides a lithium battery lamination protection plate, which is used for connecting a lithium battery, and comprises an acquisition communication plate and a power switch plate, and the acquisition communication plate and the power switch plate are laminated in the vertical direction and are electrically connected through a plug connector; an analog front-end chip and a control module are arranged on the acquisition communication board, and a power switch group is arranged on the power switch board; the analog front-end chip is used for collecting parameter information of the lithium battery, and the control module is used for transmitting the parameter information to the cloud server; the analog front-end chip is further used for sending a control signal to the power switch group according to the parameter information, and the power switch group is used for being switched on or switched off according to the control signal so as to achieve charging and discharging control over the lithium battery. The invention also provides a power battery pack and an electric vehicle. According to the lithium battery laminated protection plate, the power battery pack and the electric vehicle provided by the invention, the occupied space of the protection plate in the length and width directions is reduced, the design difficulty is reduced, and the production cost is reduced.

    本发明提供一种锂电池叠层保护板,用于连接锂电池,锂电池叠层保护板包括采集通信板及功率开关板,采集通信板与功率开关板在垂直方向上叠层设置且通过插接件电性连接;采集通信板上设置有模拟前端芯片及控制模块,功率开关板上设置有功率开关组;模拟前端芯片用于采集锂电池的参数信息,控制模块用于将参数信息传送至云端服务器;模拟前端芯片还用于根据参数信息向功率开关组发送控制信号,功率开关组用于根据控制信号导通或关断,以实现对锂电池进行充放电控制。本发明还提供一种动力电池包及电动车辆。本发明提供的锂电池叠层保护板、动力电池包及电动车辆,降低了保护板在长宽方向上的占用空间,降低了设计难度,减少了生产成本。
