The invention belongs to the field of storage batteries of electric vehicles, and provides an intelligent charging method for an electric vehicle, which comprises the following steps: acquiring a vehicle state, and awakening a body control module (BCM) according to the vehicle state; the voltage value of a storage battery is obtained, and the BCM judges the voltage value of the storage battery according to set charging conditions and sends an intelligent charging starting instruction; a vehicle control unit VCU receives the intelligent charging starting instruction, and meanwhile, controls a relay of a high-voltage system IGN2 to be closed and controls a vehicle-mounted charger assembly CMDC to charge a storage battery according to the intelligent charging starting instruction; after the vehicle-mounted charger assembly CMDC finishes charging the storage battery, the vehicle body controller BCM sends an intelligent charging finishing signal to the vehicle control unit VCU; therefore, according to the scheme, the charging condition can be intelligently judged; reasonable charging is carried out according to the voltage of the storage battery, and the charging effect is obvious; and meanwhile, the stability of charging the storage battery is improved, and the cost is saved.

    本发明属于电动汽车蓄电池领域,提供一种电动汽车智能补电方法,通过获取车辆状态,根据所述车辆状态唤醒车身控制器BCM;获取蓄电池电压值,所述车身控制器BCM根据设定补电条件判断所述蓄电池电压值并发送智能补电开启指令;整车控制器VCU接收所述智能补电开启指令,同时,根据所述智能补电开启指令控制高压系统IGN2继电器吸合并控制车载充电机总成CMDC对蓄电池充电;所述车载充电机总成CMDC对蓄电池充电结束后,车身控制器BCM向整车控制器VCU发出智能补电结束信号;由此可见,上述方案能够智能的判断补电条件;并根据蓄电池电压进行合理的补电,补电作用明显;同时提高了对蓄电池补电的稳定性,节省了成本。
