摘　　要：针对汽车蓄电池的使用工况特点,基于安时积分法、开路电压法等经典蓄电池状态计算方法,提出了一种全新的综合性电池电量计算方法,对蓄电池全工况使用过程进行实时监控。并根据汽车用电器特点,合理规划汽车用电,防止电池过度放电,实现车载蓄电池的亏电保护,保证汽车常温起动能力。最后,通过实车试验验证了该方法的可行性和有效性。In view of the working features of battery, a novel comprehensive calculation method for the state of charge （SOC） of battery is proposed based on some typical SOC algorithms such as ampere-hour integration and open circuit voltage method, so as to monitor the whole process of battery operation at real time. Furthermore, the electricity use in vehicle is properly planned according to the features of vehicle appliances to prevent battery from o- ver-discharging, achieve insufficient voltage protection of vehicle battery and ensure the starting capability of vehicle at normal temperature. Finally, the results of real vehicle tests verify the feasibility and effectiveness of the method proposed.
