A detection method for automobile power battery and management system based on DC charging pile

Abstract

The application discloses a detection method of a vehicle power battery and a management system based on a direct-current charging pile, and the detection method comprises the following steps: (1) obtaining characteristic information of a charging process through dynamic pulse detection; (2) calculating related parameters of core factors influencing the safety of charging and discharging of a battery pack and influencing the service life and driving mileage of the battery pack based on the characteristic information; and (3) analyzing the calculation result of step (2) to obtain a result. The application can obtain characteristic values of related aging degrees of battery cells by specifying special pulse charging conditions, and can realize estimation of the optimal charging current of the battery pack according to the characteristic values, so that a safe and effective charging strategy is realized.
