摘　　要：在充放电曲线移动模型的基础上,推导出了电池电量差与电池能量差的关系模型。在实际应用中,利用模型和实际运行的历史数据计算电池间的电量差。根据电量差制订均衡策略,实现全天候运行的电池均衡,并对SOC、SOE和SOH值进行修正。数据和理论在实际工程中取得了理想的效果。Based on the moving model of the charge discharge curve,a relationship model between the difference in battery quantity of charge and the difference in battery operating energy was derived.In practical applications,the difference in battery quantity of charge is calculated using the model and historical data from actual operation.Develop a balancing strategy based on the difference in battery charge state to achieve 24-hour battery balancing,and correct the SOC,SOE,and SOH values.The data and theory have achieved ideal results in practical engineering.
