  • Method and apparatus for determining state of power of battery system
    Patent number: 11639970
    Abstract: 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.
    Type: Grant
    Filed: September 6, 2020
    Date of Patent: May 2, 2023
    Assignees: CALB Co., Ltd., CALB TECHNOLOGY CO., LTD.
    Inventors: Peipei Qiao, Huaitao Wang
  • METHOD FOR CONTROL POWER OF BATTERY, CONTROL APPARATUS, AND ELECTRIC VEHICLE
    Publication number: 20210197690
    Abstract: The disclosure provides a method for control a power of a battery, a control apparatus, and an electric vehicle. By adjusting the actual power according to a difference between the rated powers and the current actual power, the power output by the battery and the power fed back to the battery can be controlled.
