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: A state-detection device, adapted in a host, includes a battery, a gas gauge, a processor, and a display. The battery is operating in an operation state. The gas gauge is configured to instantly detect the operation state and stores state information of the battery in a plurality of registers. The processor determines, according to the state information, whether the battery is operating in a normal state, a temporary failure state, or a permanent failure state to generate state-determination information. When the battery is operating in the temporary failure state, the processor further determines whether the temporary failure state is an over-temperature state, an over-voltage state, or an over-current state according to a first value, a second value, and a third value, respectively, of the state information. The display is configured to display the state-determination information.
