The invention provides a vehicle charging method and device, a vehicle and a storage medium, and the method comprises the steps: carrying out the message communication with a charging pile based on a preset target voltage value for a charging port of the vehicle before the connection between the charging pile and the vehicle is established and the charging pile and the vehicle enter an electric energy transmission stage, the port voltage of the charging port is adjusted to a target voltage value, so that the charging pile can detect a preset condition meeting an electric energy transmission stage; after entering the electric energy transmission stage, determining a charging mode matched with an output capability parameter according to the output capability parameter of the charging pile; and the vehicle is controlled to enter the charging mode, and a main relay connected with a power battery pack in the vehicle is controlled to be closed, so that the charging pile charges the vehicle. According to the method, different charging modes of the power battery can be compatible while the number of communication times between the vehicle end and the charging pile is reduced.

    本申请提供了一种车辆充电的方法、装置、车辆和存储介质,该方法包括:在充电桩与车辆建立连接且充电桩与车辆进入电能传输阶段之前,基于针对车辆的充电端口预设的目标电压值与充电桩进行报文通信,并将充电端口的端口电压调整至目标电压值,以使充电桩能够检测到满足进入电能传输阶段的预设条件;在进入电能传输阶段后,根据充电桩的输出能力参数,确定与输出能力参数匹配的充电模式;控制车辆进入上述充电模式,并控制与车辆中的动力电池组连接的主继电器闭合,以使得充电桩对车辆进行充电。该方法能够在减少车端与充电桩之间的通信次数的同时,兼容动力电池的不同充电模式。
