The invention relates to the technical field of electric vehicles, in particular to an intelligent charging control method for an electric vehicle, which comprises the following steps: when the vehicle is in a dormant state, an APP sends an instruction to a T-BOX and sends an intelligent charging starting function to the T-BOX, a VCU starts a timed awakening function after receiving an intelligent charging starting signal, the VCU reads the voltage of a storage battery, and the intelligent charging starting signal is sent to the T-BOX; and after the vehicle is powered off and locked and the VCU is dormant, timing is started, the VCU sets the timed awakening time as T1, and when the time is accumulated to T1, the VCU is awakened in a timed mode, so that the problems that the intelligent electricity supplementing function of the electric vehicle of each main engine plant does not consider that the fault of the storage battery occurs, so that the electric quantity is reduced quickly, and the service life of the electric vehicle is prolonged are solved. The problem that the user misjudges the health condition of the storage battery while the electric quantity of the power battery is lost in the prior art is solved.
本发明涉及电动汽车技术领域,具体地说,本发明涉及一种电动汽车智能补电控制方法,在汽车休眠状态,由APP向T‑BOX发送指令,向T‑BOX发送开启智能补电功能,VCU收到开启智能补电信号后,启动定时唤醒功能,VCU读取蓄电池电压,根据当前蓄电池电压查表得到当前电压对应的唤醒时间T1,车辆下电锁车后,VCU休眠后开始进行计时,VCU设定定时唤醒的时间为T1,当时间累计到T1后,VCU定时唤醒,解决了各主机厂的电动汽车的智能补电功能未考虑到蓄电池出现故障导致电量下降较快,会频繁的启动该功能为蓄电池充电,动力电池电量流失的同时,也会让用户误判蓄电池的健康状况的问题。
