Abstract: An electronic device includes a battery device, a capacity measuring unit, and a microprocessor. The battery device outputs its remaining capacity and fully charged capacity. The capacity measuring unit includes a sensing resistor, measures the battery current of the battery device using the sensing resistor, and integrates the battery current to obtain the actual capacity. The microprocessor stores the fully charged capacity. When the battery device is in a specific state, the microprocessor calculates the capacity difference between the remaining capacity and the actual capacity. The microprocessor calibrates the fully charged capacity according to the ratio of the capacity difference to the remaining capacity.

Abstract: A battery device includes a battery cell and a battery protection circuit. The battery protection circuit includes a microcontroller and a power-supply switch. The microcontroller receives a start signal, a repair signal, and an external-power-indication signal from the outside of the battery device. The power-supply switch is electrically connected to the battery cell. The microcontroller correspondingly outputs an enable signal to the power-supply switch according to the start signal and the repair signal, so that the power-supply switch disconnects the electrical connection between the battery cell and the battery protection circuit. The microcontroller correspondingly outputs a disable signal to the power-supply switch according to the start signal, the repair signal, and the external-power-indication signal, so that the power-supply switch restores the electrical connection between the battery cell and the battery protection circuit.

Abstract: A smart battery device includes a battery unit, a temperature-sensing unit and a processing unit. The temperature-sensing unit senses the ambient temperature to generate a temperature signal. The processing unit is coupled to the battery unit and the temperature-sensing unit. In a charging mode, the processing unit receives the temperature signal and obtains the power capacity of the battery unit. The processing unit sets full capacity according to the temperature signal and generates an indication flag when the power capacity of the battery unit reaches the full capacity, wherein the indication flag is used to indicate that the battery unit is in a fully charged state.
