Abstract

The invention discloses a driving device and a driving method for increasing the standby time of batteries. The method comprises the following steps: after equipment is powered off, disconnecting a battery path control module from a battery power supply module, and suspending the battery output; detecting whether there is a power-on signal sent by an external power switch trigger module detected; if there is a power-on signal sent by the external power switch trigger module detected, opening the battery path control module, and connecting the battery power supply module with a battery charging and discharging management module to form a battery power supply path; if there is no power-on signal sent by the external power switch trigger module detected, continuing detection of a signal sent by the external power switch trigger module. By adding battery power path control, the battery loss during the power-off period is reduced, and the standby time of batteries is increased.

Description

technical field [0001] The invention relates to battery standby technology, in particular to a driving device and method for increasing battery standby time. Background technique [0002] Most of the existing portable devices are powered by batteries, and are powered off when the devices are not in use. Since the battery is inside the device, it cannot be powered off by plugging and unplugging the battery, and the device can only be turned on / off by an external trigger. If the external trigger mode is used for on / off operation, the device needs to have a trigger circuit for judging the external trigger signal and a power on / off control circuit. These circuits accelerate battery standby power drain. In order to prolong the battery life and standby time, although a low-power trigger circuit and a power on / off control circuit are used, the battery itself is always on. When the device is powered off, it still consumes too much compared to the battery itself when it is suspende...
