| Abstract: | To establish the battery management system,the real-time measurement and estimation of state of charge(SOC) of power battery is the key.The advantages and disadvantages of the various battery SOC estimation methods were analyzed,and a voltage-Ah counting algorithm was proposed to detect the real-time terminal voltage as a method to determine the status of battery charge.The coulometer built by the proposed method could accurately calculate the real-time coulomb and SOC,and consequently guarantee the safe and reliable running of the power battery in the electric vehicle. |
