Title: STORAGE BATTERY LIFE PROTECTION CIRCUIT FOR ELECTRONIC DEVICE
Abstract:
A storage battery life protection circuit for an electronic device. When a storage battery (1) of an electronic device is in static storage, a charging and discharging control unit (2) controls a storage battery discharging control unit (3) and a storage battery discharging path unit (4) to be in a default status whereby the storage battery (1) is disabled to discharge, which reduces the earth impedance of the storage battery (1) to the lowest level, controls the static current of static storage and discharge of the storage battery (1) to a lowest loss state, and plays a role in protecting and extending the service life of the storage battery (1); moreover, the storage battery life protection circuit for an electronic device can maintain a reasonable logic of the use environment of the storage battery (1); in addition, if the charging and discharging control unit (2) detects that a storage power of the storage battery (1) is below 10% protection power, the charging and discharging control unit (2) protects the storage battery (1) by turning off a discharging circuit of the storage battery (1).
