Abstract:
1. A charging system adapted to charge a battery, the charging system comprising: a charger coupled to the battery to charge the battery; and a detecting unit coupled to the charger and the battery to measure a plurality of electrical parameters of the battery; wherein when the temperature of the battery is lower than a first threshold temperature, the charger charges the battery normally, when the temperature of the battery is higher than the first threshold temperature but lower than a second threshold temperature, the detecting unit determines whether electric quantity of the battery is lower than a first threshold voltage, when the temperature of the battery is between the first threshold temperature and the second threshold temperature, and the electric quantity of the battery is lower than the first threshold voltage, the charger charges the battery continuously; when the battery is coupled to an electronic device, the temperature of the battery is higher than the second threshold temperature, the electric quantity of the battery is higher than a second threshold voltage, the detecting unit starts the electronic device and discharges the battery to power the electronic device, and the second threshold voltage is lower than the first threshold voltage; and when the temperature of the battery is between the first threshold temperature and the second threshold temperature, and the electric quantity (voltage values) of the battery is higher than the first threshold voltage, the charger stops charging the battery.
