The invention relates to the technical field of vehicle charging, in particular to a charging gun unlocking method and device, a vehicle control unit, a vehicle and a storage medium, and the method comprises the steps that in the charging process of the vehicle, a charging gun unlocking instruction of the vehicle is acquired and responded, and the actual charging state of the vehicle is recognized; and under the condition that the actual charging state is a fast charging state, sending a charging termination signal to a charging device to which the charging gun belongs, so as to disconnect a fast charging relay of the vehicle when the charging current of the charging device is detected to be lower than a first preset current, and after the charging device disconnects the direct-current relay of the charging device and the voltage of the power supply interface is smaller than the preset voltage to disconnect the relay for the auxiliary power supply of the charging device, unlocking the quick charging lock of the charging device. Therefore, the problems that in the related technology, once the user wants to finish quick charging, the operation of unlocking the charging gun is complex and tedious, the user experience and the customer stickiness are reduced, and the actual use requirement of the user cannot be met are solved.

    本申请涉及车辆充电技术领域,特别涉及一种解锁充电枪的方法、装置、整车控制器、车辆及存储介质,其中,方法包括:在车辆处于充电的过程中,获取并响应车辆的充电枪解锁指令,识别车辆的实际充电状态;在实际充电状态为快充状态的情况下,发送充电终止信号至充电枪所属的充电装置,以在检测到充电装置的充电电流低于第一预设电流时,断开车辆的快充继电器,并在充电装置断开充电装置的直流继电器且供电接口电压小于预设电压以断开充电装置辅助电源用继电器后,解锁充电装置的快充锁。由此,解决了相关技术中,一旦用户想要结束快充,解锁充电枪的操作复杂繁琐,降低了用户体验和客户粘性,无法满足用户的实际使用需求等问题。
