  • Method, apparatus, device and medium for estimating performance parameters of a battery
    Patent number: 11573273
    Abstract: The present application discloses a method, apparatus, device and medium for estimating performance parameters of a battery. The method for estimating performance parameters of a battery includes: generating a first curve segment to be calibrated during a process of adjusting a battery capacity in a first capacity interval with a first capacity value as an endpoint value; determining, in a preset reference curve, a first target curve segment that matches the first curve segment to be calibrated; determining a SOC interval corresponding to the first target curve segment as a SOC interval of the first curve segment to be calibrated; and estimating the performance parameters of the battery based on the SOC interval of the first curve segment to be calibrated, the performance parameters include a current SOC and/or a current battery capacity.
