    Abstract: A battery device is provided. The battery device includes: a battery module, a protection device, a battery management circuit, and a battery protection circuit. The battery module includes one or more battery cells. The battery management circuit is for managing the protection device and charging and discharging of the battery module. When the battery device is in a charging mode, the battery protection circuit periodically checks and calculates a direct current internal resistance (DCIR) of the battery module, and determines a current operation temperature of the battery module and a temperature range corresponding to the current operation temperature. When the battery protection circuit determines that the DCIR is greater than a predetermined multiple of a first threshold corresponding to the temperature range, the battery protection circuit informs the battery management circuit to cut off the protection device.

    Abstract: An electronic device is provided. The electronic device includes a main system processing a process, a power control unit and a battery module. The power control unit provides operating power to the main system via an external power source when the external power source has been connected, and detects whether the power control unit has received a battery protection signal. The battery module discharges with a self-discharge rate when the battery module has received the protection signal from the power control unit. When the power control unit has not received the battery protection signal, the power control unit provides a charging power to the battery module via the external power source. When the power control unit has received the battery protection signal, the power control unit does not provide the charging power to the battery module, and transmits the protection signal to the battery module.

    Abstract: A battery device includes at least a battery cell, a management chip and a bus. The management chip is coupled to the battery cell for detecting voltage or remaining capacity of the battery cell and managing an operation state of the battery device according to the voltage or the remaining capacity of the battery cell. The bus is coupled to the management chip. The management chip communicates with a host device via the bus. The management chip further determines whether the remaining capacity of the battery cell is not increasing while in a charging state. When the remaining capacity of the battery cell is not increasing while in the charging state, the management chip activates a protection mechanism to make the battery device exit the charging state.

    Abstract: A power management circuit for a battery cell is provided. The battery cell is coupled to a load through an output terminal. The power management circuit includes a current detection circuit, a loading determination circuit, and a voltage determination circuit. The current detection circuit detects a discharge current of the battery cell when the battery cell is discharged through the load to generate a discharge-current signal. The loading determination circuit determines a loading value of the load according to the discharge-current signal to generate a loading signal. When the battery voltage of the battery cell drops to the cut-off voltage, the power management circuit terminates the discharge of the battery cell through the load.
