Vehicle battery system matching identification method and device and vehicle

The invention discloses a vehicle battery system matching identification method and device and a vehicle, and relates to the technical field of vehicles. The method comprises the steps that battery adaptation information of the vehicle is obtained, and the battery adaptation information is used for replacing a power battery of the vehicle; identifying whether the battery type information of the battery library is matched with the battery adaptation information; and under the condition that it is determined that the battery type information of the battery library is not matched with the battery adaptation information, a control strategy set is generated, and the control strategy set is at least used for controlling the vehicle to prohibit high-voltage power-on. The technical problems that the battery is not matched with the vehicle after battery replacement due to different types and parameters of the battery, the function of the vehicle is limited, and the service life of the battery is shortened are solved.
