Abstract: A power protection method for an electronic device includes supplying power to an electronic device through a power supply path, detecting a positive current of the power path, detecting a negative current of the power path, comparing a current amount of the positive current with a current amount of the negative current, and disconnecting the power path when the current amount of the positive current is not equal to the current amount of the negative current.

Abstract: A battery safety management procedure applicable to a battery safety management system is provided. The battery safety management system includes a controller, storage, and battery. The battery safety management procedure is stored in the storage and executed by the controller to perform steps of: determining whether a power level of the battery is greater than or equal to a power level threshold and determining whether a power storage time is greater than or equal to a time threshold; and performing a discharging procedure when the power level of the battery is greater than or equal to the power level threshold, and the power storage time is greater than or equal to the time threshold. Time control and power level control prevents the battery from being in a prolonged state of high power level to reduce the chance of battery swelling, leaks, abnormalities, and damage, thereby extending battery service life.

Abstract: A charging method includes calculating a remained lifetime of a battery unit based on a health state and a battery temperature of the battery unit, charging the battery unit by a charging voltage with a first potential when the remained lifetime is higher than a lifetime threshold, and charging the battery unit by the charging voltage with a second potential when the remained lifetime is smaller than or equal to the lifetime threshold.

Abstract: An electronic device includes a system circuit, a power connector, a path selection circuit, a plurality of battery connectors, a plurality of series circuits, and a control circuit. The power connector is suitable for receiving power. The path selection circuit is coupled to the system circuit and the power connector. The battery connectors are respectively suitable for coupling a plurality of batteries. The series circuits respectively correspond to the battery connectors, and each series circuit is connected between the corresponding battery connector and the path selection circuit. Each series circuit includes: a charging switch, a battery switch and a discharging path. In a sequential discharge mode, the control circuit controls the series circuits to turn on the battery switch thereof in turn and controls the path selection circuit to connect the series circuits to the system circuit. The remaining battery switches and all charging switches remain off.
