The invention discloses a vehicle charging method and device and a charger, and the vehicle charging method comprises the steps: in a charging parameter configuration stage, a vehicle sends a vehicle charging parameter message to the charger, and receives a charger maximum output capability message sent by the charger; in the charging stage, the vehicle sends a battery charging demand message and a battery charging total state message to the charger, and receives a charger charging state message sent by the charger; if current-related parameters in the vehicle charging parameter message, the charger maximum output capability message, the battery charging demand message, the battery charging total state message and the charger charging state message are smaller than or equal to the charging current maximum limit value, configuration is carried out according to a standard communication protocol; and if the charging current is greater than the charging current maximum limit value, performing configuration in a complement form. The problem that the communication requirement of high-power charging cannot be met in an existing standard communication protocol is solved.

    本发明公开了一种车辆充电方法、装置及充电机,所述车辆充电方法包括在充电参数配置阶段,车辆向充电机发送车辆充电参数报文,接收充电机发送的充电机最大输出能力报文;在充电阶段,车辆向充电机发送电池充电需求报文和电池充电总状态报文,接收充电机发送的充电机充电状态报文;对于车辆充电参数报文、充电机最大输出能力报文、电池充电需求报文、电池充电总状态报文和充电机充电状态报文中的与电流相关参数,若其小于或等于充电电流最大限值,则按照标准通信协议进行配置;若其大于充电电流最大限值,则采用补码形式进行配置。本发明解决了现有标准通信协议中无法满足大功率充电的通信需求问题。
