Method of preventing battery over-discharge and a battery pack with a battery over-discharge prevention circuit |
摘要 |
The method of preventing battery over-discharge measures battery voltage with a control circuit, and switches an over-discharge protection switch connected in series with the batteries off with the control circuit when battery voltage drops below a minimum set voltage. Once the over-discharge protection switch turns to an off state, the off voltage at the output side of the switch is measured, and the over-discharge protection switch is held in the off state by this off voltage. When battery voltage rises above the minimum set voltage, return of the over-discharge protection switch to the on state is prevented.
