Problems solved by technology

[0003] At present, there is no simple and convenient way to obtain the SOH value of the electric vehicle battery pack. The existing methods for estimating the SOH value of the battery rely more on the experience level of professional technicians, and cannot obtain a more accurate SOH value of the battery.

Abstract

The invention discloses a method for estimating the SOH of an electric vehicle. The method includes: obtaining the charging capacity of the battery charged to SOC100% and the discharging capacity of the battery; obtaining the capacity value of the battery according to the first preset formula according to the charging capacity and the discharging capacity; according to the first preset formula according to the capacity value; The second formula obtains the SOH value of the battery. The invention also discloses an electric vehicle SOH estimation device and a computer-readable storage medium. The invention can realize relatively simple acquisition of the SOH value of the battery.

Description

technical field [0001] The present invention relates to the field of television interaction, in particular to a method, device and computer-readable storage medium for estimating the SOH of an electric vehicle. Background technique [0002] SOH (State Of Health) refers to the battery capacity, health, and performance status, that is, the percentage of the full charge capacity of the battery relative to the rated capacity. It is 100% for a new factory battery and 0% for a completely scrapped battery. The SOH value of the battery reflects the health status of the battery. As the capacity of the battery continues to decay during use, the difference in consistency of the battery gradually increases, and the SOH value of the battery is also constantly decaying. [0003] At present, there is no simple and convenient way to obtain the SOH value of the electric vehicle battery pack. The existing methods for estimating the SOH value of the battery rely more on the experience level o...
