Abstract

The present invention relates to the field of battery technology, and its embodiment provides a battery parameter calibration method based on a genetic algorithm. The calibration method includes: based on the test data related to the identification parameters, constructing A battery simulation model; determine the fitness function of the battery simulation model and the initial range of the identification parameters according to the aging degree of the battery; use an adaptive genetic algorithm to determine the optimal solution of the identification parameters, and convert the optimal The solution is used as the calibration parameter of the battery. At the same time, a corresponding battery parameter calibration system and equipment based on the genetic algorithm are also provided. Embodiments of the present invention are used to quickly and accurately calibrate battery parameters.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery parameter calibration method based on a genetic algorithm, a battery parameter calibration system based on a genetic algorithm, and a battery parameter calibration device based on a genetic algorithm. Background technique [0002] At present, new energy vehicles are being vigorously promoted both at home and abroad. Compared with traditional cars, electric vehicles have great advantages in driving economy and driving comfort, but the cost of electric vehicles is mainly concentrated in the power battery. The performance and life of the power battery are greatly affected by temperature, and the battery performance parameters are also different at different temperatures. Therefore, it is necessary to specify a reasonable battery thermal management to make the electric power battery work at a suitable temperature. To formulate a suitable battery thermal management strate...
