The invention provides a method and a system for realizing a new energy vehicle reserved charging function, charging control of a new energy vehicle is carried out according to acquired reserved charging time or reserved charging electric quantity, and after charging is started, a charging state is judged according to a charging current signal, the method comprises the following steps: judging whether the charging current is negative or not, and if the charging current is a negative value, the charging state is judged; if yes, charging execution success is fed back; if the current is a non-negative value, judging whether the SOC is 100%, if the SOC value is 100%, feeding back that charging execution succeeds, if the SOC value is not 100%, judging the charging state, if the charging state is heating, feeding back that charging execution succeeds, and if the charging state is not heating, feeding back that charging execution fails; according to the invention, the charging execution condition in the charging process is judged in real time, and the charging current and the SOC are combined, so that the safety and intelligence in the reservation charging process are improved at the same time.
本发明提供了一种实现新能源车辆预约充电功能的方法及系统,根据获取的预约充电时间或者预约充电电量,进行新能源车辆的充电控制,在开始充电后,根据充电电流信号,判断充电状态,包括:判断充电电流是否为负,如充电电流为负值,则反馈充电执行成功;如电流为非负值,则判断SOC是否为100%,如果SOC值为100%,则反馈充电执行成功,如果SOC不是100%,则判断充电状态,如充电状态为加热,则反馈充电执行成功,如不为加热,反馈充电执行失败;本发明实时的对充电过程中的充电执行情况进行判断,结合充电电流和SOC,同时提高了预约充电过程中的安全性和智能性。
