Abstract: A battery module and a short protection method thereof are provided. The battery module has a battery cell pack and a control circuit. The method includes: detecting a temperature of the battery cell pack as a battery cell temperature through the control circuit; determining whether the battery cell temperature shows a downward trend when the battery cell temperature is higher than a first predetermined temperature value; and deactivating the battery module when the battery cell temperature does not show the downward trend.

Abstract: The disclosure provides a power management method. The power management method is applicable to an electronic device. The electronic device is electrically coupled to an adapter, and includes a system and a battery. The adapter has a feed power. The battery has a discharge power. The power management method of the disclosure includes: reading a power value of the battery; determining a state of the system; and discharging power to the system, when the system is in a power-on state and the power value is greater than a charging stopping value, by using the battery, and controlling, according to the discharge power and the feed power, the adapter to selectively supply power to the system. The disclosure further provides an electronic device using the power management method.
