Abstract

The invention provides an under-voltage protection circuit and a protection method. A battery pack charges a battery management system through a switching power supply; when the battery pack voltage is less than a first threshold, the battery management system and the switching power supply are powered off. When the battery has a power shortage risk, all power consumption loops can be cut off in time, and the battery is protected.

Description

technical field [0001] The invention relates to the field of battery management systems, in particular to an undervoltage protection circuit and a protection method. Background technique [0002] The power supply of the battery management system BMS needs to be obtained from the battery. When the battery management system BMS is left uncharged for a long time, it will cause the battery to run out of power or even irrecoverably damaged. If a manual switch is used to control the power supply of the battery management system BMS, the autonomous protection function of the battery management system BMS cannot be realized. If human factors forget to turn off the manual switch, the battery will also be damaged due to power loss. Contents of the invention [0003] The purpose of the present invention is to provide an undervoltage protection circuit and protection method, which are used to solve the problem of battery power loss and damage in the prior art. [0004] To achieve the...
