The invention provides an automobile charging port locking system and a control method thereof. The system comprises a charging gun state monitoring circuit, a charging port cover position sensor, a charging port spring bolt device and a charging port locking control module. The charging gun state monitoring circuit is used for monitoring whether a charging gun is inserted in place and whether a charging gun button is pressed down; the charging port cover position sensor is used for monitoring whether the charging port cover is opened or not; the charging port spring bolt device is used for prohibiting the charging gun from being inserted or pulled out or allowing the charging gun to be inserted or pulled out; the charging port locking control module monitors the state of the charging gunand the state of the charging port cover and communicates with the vehicle control unit, and then locking and unlocking of the charging port spring bolt device are controlled. The charging gun is forbidden to be inserted under a dangerous working condition, charging is forbidden when the charging gun is not inserted in place, the charging gun is allowed to be pulled out when the battery is fully charged or reaches a charging limit value but the whole vehicle is not unlocked, and the charging safety and the utilization efficiency of the charging pile are improved.

    本发明提供了一种汽车充电口锁定系统及其控制方法。系统包括充电枪状态监测电路、充电口盖位置传感器、充电口锁舌装置、充电口锁定控制模块;充电枪状态监测电路用于监测充电枪是否插入到位以及充电枪按钮是否被按下;充电口盖位置传感器用于监测充电口盖是否被打开;充电口锁舌装置用于禁止充电枪的插入或拔出,或者允许充电枪的插入或拔出;充电口锁定控制模块监测充电枪状态以及充电口盖状态,并与整车控制器通信,进而控制充电口锁舌装置的锁定与解锁。本发明可实现禁止在危险工况下插入充电枪,禁止在充电枪未插到位的状态下充电,允许在电池已经充满电或达到充电限值但整车未解锁的状态下拔出充电枪,提高了充电安全性和充电桩利用效率。
