The invention relates to the technical field of electric automobile charging, in particular to an automobile charging pile power supply method and a charging pile. The method comprises the steps of detecting the power supply state of the charging pile, and obtaining the charging state of the charging pile for an automobile; when the power supply state of the charging pile is power-off, obtaining power failure time of the charging pile; when the power supply state of the charging pile is power supply recovery, judging the type of a clock module, and obtaining power supply recovery time of the charging pile according to the type of the clock module; calculating the actual power failure time of the charging pile according to the power supply recovery time and the power failure time; and according to the actual power failure time and the charging state of the automobile before the charging pile is powered off, judging whether the authorized charging action is started or not, and calibrating the system time of the charging pile. The system time of the charging pile is automatically recovered. The bottleneck that the charging state of the automobile cannot be recovered after the charging pile is powered off is broken through.

    本发明涉及电动汽车充电技术领域,具体涉及一种汽车充电桩供电方法和充电桩,包括以下步骤:检测充电桩的供电状态,并获取充电桩对汽车的充电状态;充电桩的供电状态为断电时,获取充电桩的断电时间;充电桩的供电状态为恢复供电时,判断时钟模组的类型,并根据时钟模组的类型得出充电桩的供电恢复时间;根据所述供电恢复时间和断电时间计算充电桩的实际掉电时间;根据实际掉电时间和充电桩断电前对汽车的充电状态,并判断是否启动授权充电动作,并对充电桩的系统时间进行校准,具有自动恢复充电桩系统时间的优点,本发明突破了充电桩断电后无法恢复汽车充电状态的瓶颈。
