More Information
Summary:A battery control device and a battery capacity estimation method are provided. The battery control device includes a current detector and a processor. The current detector detects the battery. The processor is electrically connected to the current detector. The processor performs coulomb current integration to obtain the integrated value based on a current detection result of the battery detected by the current detector during a sampling period. The processor multiplies the integrated value by a battery coulomb beta coefficient to obtain a depth of discharge. The processor calculates a first relative state-of-charge of the battery according to the depth of discharge and determines remaining battery power information according to the first relative state-of-charge.
