Abstract
A built-in battery controller for a personal telecommunication device. The battery controller includes a push switch that is switched on and off by a user, a power control unit that is connected to the push switch and allows a leakage current to flow through the power switch, a battery pack including a protection circuit module (PCM) for turning off the battery when the leakage current flows through the power switch under the control of the power control unit, and a charging circuit for charging the battery pack. The battery controller can be simply operated and can more reliably turn off the battery without affecting the outer appearance of the device.
Claims10
A battery controller, comprising:
- a push switch operable to be switched on and off;
- a power switch connected to the push switch and operable to allow a leakage current to flow through the power switch based on input from the push switch;
- a battery pack including a battery and a protection circuit module (PCM) for turning off the battery when the leakage current flows through the power switch;
- and
- a charging circuit for charging the battery pack.
A battery controller, comprising:
- a switch;
- means connected to the switch operable to allow a leakage current to flow to a battery pack based on input from the switch;
- the battery pack including a battery, means for detecting the leakage current, and means for turning off the battery when the leakage current is detected;
- and
- means for charging the battery pack.
