Description: The estimation of battery charge state is the core content of battery management system. Whether the estimation is accurate or not will directly affect the decision and control of battery management system. On the basis of open circuit voltage method and time method. Taking full advantage of the modified function of extended Calman filter, the effect of battery charge discharge ratio, temperature and charge discharge cycle times on the battery is taken into consideration. The correction algorithm of Calman filter is proposed and applied to the battery management system of the plug-in hybrid electric vehicle.
