The invention provides a method for measuring the lowest starting electric quantity of an automobile storage battery, which can be applied to the technical field of storage batteries, the battery is connected with an electronic load and a direct-current power supply, and comprises the following steps: controlling the electronic load to discharge the storage battery with preset electric quantity at least once according to a discharge proportion, and controlling the automobile to start after the storage battery is discharged every time, wherein the discharge proportion is the proportion of the total capacity of the storage battery. If the automobile is successfully started, the lowest starting electric quantity of the storage battery is not reached, the electronic load is controlled to discharge the storage battery next time according to the discharge proportion, and if the automobile is failed to start and the lowest starting electric quantity of the storage battery is just reached, the direct-current power supply is controlled to charge the storage battery; and the electric quantity of the storage battery reaches the total capacity of the storage battery. And then determining the charging electric quantity of the storage battery, and determining the minimum starting electric quantity of the storage battery according to the charging electric quantity and the total capacity, so that the minimum starting electric quantity of the storage battery can be calculated and accurately measured.

    本申请提供一种汽车蓄电池最低启动电量的测量方法,可应用于蓄电池技术领域,电池与电子负载以及直流电源连接,包括:控制电子负载对预设电量的蓄电池按照放电比例进行至少一次放电,在每次蓄电池放电完成之后,控制汽车启动,其中,放电比例为所述蓄电池的总容量的比例。若汽车启动成功,说明未达到蓄电池的最低启动电量,则控制电子负载,按照放电比例对蓄电池进行下一次的放电,若汽车启动失败,明刚好达到蓄电池的最低启动电量,则控制直流电源对蓄电池进行充电,直至蓄电池的电量达到蓄电池的总容量。然后确定蓄电池的充电电量,根据充电电量与总容量确定蓄电池的最低启动电量,这样即可计算出精确测量蓄电池的最低启动电量。
