1. A method for obtaining degradation of a battery, comprising:
collecting data of the battery and data related to the degradation of the battery, and processing the collected data to obtain parameters related to the degradation of the battery; creating and updating a degradation model for the battery using the obtained parameters; computing the degradation of the battery using the degradation model and the parameters related to the degradation; creating an initial degradation model for the battery or updating the computed degradation model or calibrating the degradation model, based on the values of actually measured battery degradation and the obtained parameters related to the degradation; storing successively the obtained parameters related to the degradation to form a degradation parameter log; and displaying when the battery has to be changed based on the degradation model, wherein the parameters related to the degradation comprises a quadrant parameter set of a parameter of the battery, a parameter of vehicle type and on-vehicle electronics, a parameter of traveled road condition, and a parameter of environment. |
