The invention relates to a power-off protection system of a low-voltage lithium battery assembly, and a control method thereof. The system comprises a mobile terminal, a T-BOX and the low-voltage lithium battery assembly, and the low-voltage lithium battery assembly comprises a battery management system and a low-voltage lithium battery pack; the mobile terminal is used for sending a power-off request to the T-BOX; the T-BOX is in communication connection with the mobile terminal and the battery management system and is used for receiving a power-off request sent by the mobile terminal and converting the power-off request into a power-off signal; and the battery management system is used for powering off the low-voltage lithium battery pack according to the power-off signal sent by the T-BOX. Through interaction of the mobile terminal, the T-BOX and the battery management system, non-contact power-off protection of the low-voltage lithium battery pack is realized.

    本发明涉及一种低压锂电池组件的断电保护系统及其控制方法,其系统包括:移动终端、T-BOX和低压锂电池组件,其中低压锂电池组件包括电池管理系统和低压锂电池组;所述移动终端,用于向T-BOX发出断电请求;所述T-BOX分别与移动终端和电池管理系统通信连接,用于接收移动终端发出的断电请求,并将断电请求转化为断电信号;所述电池管理系统,用于根据T-BOX发出的断电信号,对低压锂电池组进行断电。本发明通过移动终端、T-BOX和电池管理系统的交互,实现了非接触式对低压锂电池组的断电保护。
