Battery capacity active estimation method used for electric vehicle
The present disclosure relates to a battery capacity active estimation method for an electric vehicle. The method is capable of determining the battery capacity based on estimating a State Of Charge (SOC) of the battery before and after a discharge operation but without having to wait until an establishment of sufficient thermal and electric equilibria in the battery. The estimation of SOC may even be made while the battery is being slowly charged. Depending on the equilibrium state of the battery, SOCs may be either directly obtained by measuring Open Circuit Voltage of the battery when the battery is in electric equilibrium or calculated and estimated when the battery is not in electric equilibrium.
