The invention discloses an intelligent charging control method and system for a pure electric vehicle, and relates to the field of electric vehicle energy management.The method comprises the steps that when T-Box awakening preconditions are met, T-Box awakening is conducted at regular time so as to detect the vehicle condition, and when the voltage of a storage battery is lower than a set value, a VCU is activated; the VCU judges a charging condition, and starts the DCDC converter to charge the storage battery when the charging condition is met; and the T-Box detects the voltage of the storage battery, and after the voltage of the storage battery reaches a set voltage, the T-Box continues charging for a set time and then stops charging the storage battery. According to the invention, the convenience of charging work of the storage battery can be realized.

    本发明公开了一种纯电动车智能补电控制方法及系统,涉及电动车能量管理领域,该方法包括当T‑Box唤醒前置条件满足时,T‑Box定时唤醒以进行车辆状况检测,并当蓄电池电压低于设定值时激活VCU;VCU进行充电条件判定,并当充电条件满足时启动DCDC转换器以对蓄电池进行补电;T‑Box进行蓄电池电压检测,并当蓄电池电压达到设定电压后继续补电设定时间然后停止对蓄电池的补电。本发明能够实现蓄电池补电工作进行的便捷性。
