The invention discloses an electric vehicle storage battery charging control method and system. The electric quantity information of a storage battery is collected; judging whether the storage battery is lack of electricity according to the electric quantity information; if the electric quantity of the storage battery is smaller than the first calibration value, the storage battery is in a power-lack state, and a first wake-up signal is sent; receiving the first wake-up signal, and sending a power-lack signal to a communication device of a driver; therefore, a driver can know the electric quantity state of the storage battery in time through the communication equipment, measures of closing the power consumption accessory are taken, continuous power consumption of the power consumption accessory is avoided, and the power consumption efficiency is greatly improved. If the power-up signal from the communication equipment is received, a second wake-up signal is sent out; if the electricity supplementing signal from the communication equipment is not received within the calibration time value, a third wake-up signal is sent out; and receiving the second wake-up signal or the third wake-up signal, powering on an ON gear for the electric vehicle, sending a high-voltage powering-on request, and controlling the high-voltage power battery to charge the storage battery to prevent the storage battery from being lack of electricity.

    本发明公开了一种电动车蓄电池补电控制方法及系统,采集蓄电池的电量信息;根据电量信息,判断蓄电池是否亏电;若蓄电池的电量小于第一标定值时,蓄电池为亏电状态,发出第一唤醒信号;接收所述第一唤醒信号,并向驾驶员的通信设备发送亏电信号;这样驾驶员就能够通过通信设备及时知道蓄电池的电量状态,采取关闭耗电附件的措施,避免耗电附件持续耗电,大大提高了用电效率。若接收到来自通信设备的补电信号,则发出第二唤醒信号;若在标定时间值内未接收到来自通信设备的补电信号,则发出第三唤醒信号;接收第二唤醒信号或第三唤醒信号,给电动车上ON档电,并发出上高压请求,并控制高压动力电池对蓄电池进行补电,防止蓄电池亏电。
