METHOD AND APPARATUS FOR DETERMINING STATE OF POWER OF BATTERY SYSTEM

The disclosure discloses a method and an apparatus for determining a state of power (SOP) of a battery system. With the method and apparatus, battery health state indexes determined according to the internal resistance and the current power of the battery system may serve as a calibration index, and the initial power parameters may be calibrated by using the calibration index. The internal resistance of the battery reflects the aging property of the battery system. Therefore, in the disclosure, the initial power parameters are calibrated according to the aging property of the battery system. By doing so, the capability of the battery system for supplying power can be more reliably reflected, so that the battery system can exhibit outstanding performance, and the energy supplied by the battery system can be utilized sufficiently and effectively.
