Abstract: n order to solve the problem that the static current parameters of vehicle with grading dormancy function cannot be correctly calculated, this article provide a method of calculating static current parameter of vehicle, by means of detecting the voltage of standing vehicle battery regularly, via SOC-V characteristic curve of the battery, calculate static current parameter of vehicle correctly, provide reference for battery selection. At the same tine, the data is used to verify the effectiveness of the grading dormancy strategy.

Key words: Static current; Dormancy; Standing; Grade

摘要： 为了解决带分级休眠功能的汽车静态电流参数无法准确计算的问题，文章提供一种车辆静态电流参数的计 算方法，通过定时检测静置车辆蓄电池电压，借助蓄电池 SOC-V 特性曲线，准确计算车辆的静态电流参数，为蓄 电池选型提供参考依据，同时用数据验证了分级休眠策略的有效性。
