New Method for Estimation Modeling of SOC of Battery

The state of charge (SOC) of battery is a import thing in battery manage system. In order to predict the SOC of battery during discharge, by analyzing the factors influenced the SOC of battery, a new method investigates the SOC of battery with fuzzy neural network which can be used to approach non-linear function with many input/output parameters. Simulated results and experimental results show the advantages of the new technique, and a novel method is presented for estimation modeling of the SOC of battery.
