The battery capacity, which changes dynamically with environmental factors, is used as a constant in the traditional ampere-hour integral method, and that will also cause some errors.
Then, the actual battery capacity prediction value was used to replace the battery rated capacity in the traditional ampere-hour integral method, and the value was brought into the improved ampere-hour integral method for SOC estimation.
Typically, the SOH of a battery can be inferred from external measurements of voltage, current, and temperature. Currently, research on estimating the SOH of power batteries mainly falls into three directions: model-based methods, traditional machine learning-based methods, and deep learning-based methods .
Capacity estimation was performed using a fuzzy neural network algorithm, with a maximum relative error of 4.5 %, which effectively described the aging trend of the battery modules.
Zhang et al. established an SOH estimation model using the average Fréchet distance method, observing the internal resistance parameters Rs, Rct, and Rf during the aging process of battery modules, and found that these parameters could serve as features for estimating the SOH of battery modules.
The accurate battery theoretical model is an important basis for system efficiency calculation, precise discharge control, and remaining capacity prediction. To this purpose, an experimental platform for electromagnetic launch is built, and discharge characteristics of the battery under different rate, temperature, and life decay are measured.
