Abstract: Vehicle power mode switch to ACC/ON, using on-board electrical appliances in ACC/ON for a long period of time, will cause battery power-lack or even loss of power, the vehicle might can't be started when it is used again. The article mainly studies how to accurately calibrate the voltage threshold of the power loss, and how to effectively prevent the power loss through the control strategy.

Key words: Battery; Power-lack; Voltage threshold

摘要： 车辆电源状态切换至 ACC/ON 挡，如果长时间在这种电源状态下使用车载用电器，将会引起低压铅酸蓄电 池电量过低甚至亏电[1]，进而导致再次用车时车辆无法正常启动。文章主要研究如何准确地标定出亏电电压阈值， 并通过控制策略如何有效地预防亏电发生。
