The establishment of coulombic model and power model of the battery used in electronic vehicle (EV) and hybrid electric vehicle (HEV) was discussed. A novel estimation method of state of charge (SOC) integrating with power capability was also introduced.

• 讨论了电动车 (EV)和混合电动车 (HEV )用电池电量模型和功率模型的建立 ,提出了一种新的电池剩余电量(SOC)和电池功率强度 (Powercapability)的综合估计方法。
