The invention provides a low-voltage lithium battery wake-up circuit. The low-voltage lithium battery wake-up circuit comprises a lithium battery module, a battery management module, a main loop switch module and a wake-up switch module which are electrically connected in sequence, the wake-up switch module is used for generating an enable signal to wake up the battery management module; the lithium battery module is used for supplying power to the wake-up switch module, the main loop switch module and the whole vehicle ECU module; the battery management module is used for receiving an enable signal of the wake-up switch module, judging the switch wake-up state of the wake-up switch module according to the enable signal, and sending a control signal to the main loop switch module to control the main loop switch state of the main loop switch module; and the main loop switch module is used for controlling the main loop switch state according to the control signal. The problems that in the prior art, when a low-voltage lithium battery needs to be awakened, professional knowledge is needed, operation is complex, and meanwhile external power connection equipment and professional tools are needed can be solved.

    本发明提供了一种低压锂电池唤醒电路,其包括依次电连接的:锂电池模组模块、电池管理模块、主回路开关模块及唤醒开关模块;唤醒开关模块用于产生使能信号,给电池管理模块完成唤醒;锂电池模组模块用于给唤醒开关模块、主回路开关模块以及整车ECU模块供电;电池管理模块用于接收唤醒开关模块的使能信号,根据使能信号判断唤醒开关模块的开关唤醒状态,并发送控制信号给主回路开关模块控制所述主回路开关模块主回路开关状态主回路开关模块用于根据控制信号控制主回路开关状态。本发明可以解决现有技术中低压锂电池需要唤醒时存在着需要专业知识且操作复杂,同时需要有外部搭电设备和专业工具的问题。
