Abstract
A charging and discharging system for a battery includes an adapter, a charging controller, a converting module, and a battery. The adapter receives an AC voltage, converts the AC voltage to a DC voltage, and electrically connects the charging controller to the converting module. When the adapter is supplying power, the charging controller can switch on and switch off the converting module, and the converting module accordingly connects and disconnects the adapter to or from the battery. When the adapter is not supplying power, the battery provides power for the electronic device. Therefore, the battery is electrically isolated from the adapter and can be protected from a sudden power surge when the adapter is powered on.
Claims15
A charging and discharging system comprising:
- an adapter being adapted to receive an alternating current (AC) and convert the AC to a direct current (DC);
- a charging controller electrically connected to the adapter;
- a converting module electrically connected to the adapter;
- and
- a battery electrically connected to the converting module,
- wherein the charging controller is electrically connected to the adapter and the converting module;
- when the adapter is in a power supply state, the charging controller is adapted to send a signal to switch on/off the converting module, and the converting module is adapted to connect/disconnect the adapter with the battery and an electronic device;
- and when the adapter is not in the power supply state, the battery is adapted to provide power for the electronic device.
A charging and discharging battery method, the method comprising:
- monitoring whether a adapter is in a power supply state by a charging controller;
- sending a signal to switch on/off a converting module to connect/disconnect the adapter with an electronic device and a battery by the charging controller when the adapter is in the charging state;
- and
- providing power for the electronic device by the battery when the adapter is not in the power supply state.
