A new model for State-of-Charge (SOC) estimation for high-power Li-ion batteries

► Build a working model to eliminate the drift noise existing in the current sensor. ► Re-describe the effect of the temperature and charge-discharge rate to the SOC. ► Model the attenuation of the battery using the data from EV in the past 3 years. ► The UPF method is applied to estimate the SOC to improve the robustness.
