Estimation of SOH of battery based on Coup de fouet
YUAN Shikui;CHENG Li;School of Energy and Environment, Southeast University;
The strong correlation between Coup de fouet and SOH(state of health) of the battery had been found in the discharge process of fully charged battery. The trough voltage and plateau voltage would be impacted much in different discharge conditions(temperature, discharge rate). According to the Coup de fouet characteristic of battery, the SOH is taken as the output variable with the trough voltage, plateau voltage, discharge rate and temperature as input variables, and a battery SOH estimation model based on BP neural network was built. The results showed that the network model could identify SOH precision and was very suitable for battery SOH online estimation.
