LOW-VOLTAGE PROTECTION DEVICE FOR USE IN STORAGE BATTERY

WIPO Patent Application WO/2018/077027

A1

Disclosed in the present invention is a low-voltage protection device for use in a storage battery, comprising: a primary power supply circuit, the primary power supply circuit being connected with the storage battery and a control system, respectively; an activation circuit, for controlling the primary power supply circuit to be connected, such that the storage battery supplies power to the control system; a low-voltage canceling circuit, for controlling, when the voltage of the storage battery is lower than a working voltage of the control system, the activation circuit to be disconnected such that the primary power supply circuit may be disconnected; and a recovery circuit, for controlling the activation circuit to be connected as triggered by a user. When the primary power supply circuit is disconnected, the activation circuit may be used to control the primary power supply circuit to be connected only when triggered by a user, such that the storage battery supplies power to the control system, thereby effectively preventing a low-voltage oscillation scenario caused by the storage battery directly supplying power to the control system, and preventing damages from occurring in the control system.
