Embodiment Construction

[0021] Embodiments of the present invention are described in detail below in conjunction with the accompanying drawings:

[0022] A method for identifying vehicle information when charging, the method specifically includes the following steps:

[0023] 1. After the vehicle is connected to the charging device, according to the requirements of the national standard communication protocol, it is necessary to use CAN communication for information interaction. In CAN communication, all information, including the license plate number information, is sent in binary form, and the license plate number information is passed through a certain Mapping relationship, the license plate number information is converted into binary form, for example, by using at least 5 binary digits to represent the province and city codes, such as 1 for Beijing, 2 for Shanghai..., using a five-digit binary length can complete 31 The representation of a province code; except for the province code, each other c...

Abstract

The invention discloses a method and device for identifying vehicle information in the charging process. The method for identifying the vehicle information comprises the following steps that a vehicleis connected with charging equipment, and a BMS transmits license plate number information to the charging equipment; the license plate number information is analyzed so as to obtain the vehicle information, according to the obtained vehicle information, the charging equipment performs charging protection actions and charging permission / prohibition actions, and meanwhile, the license plate numberinformation is displayed on an interface of a charging machine. By means of the method, the problem that the vehicle information is difficult to identify when a VIN code is used is solved, so that great convenience is brought to vehicle identification, moreover, fees can be collected according to vehicles, and owner information can be found in a database for service sales.

Description

technical field [0001] The invention belongs to the field of vehicle identification, in particular to a method and device for identifying vehicle information during charging. Background technique [0002] With the development of the automobile industry, automobiles are becoming more and more electrified and intelligent. With the development of electrification, more and more automobiles use charging to supplement energy. The car can be charged on any charging device that meets this standard. During the charging process, it is often necessary to know which vehicle is being charged on the charger. In the national standard, the method that can use the VIN code for vehicle identification is stipulated. [0003] The Vehicle Identification Number (VIN) is a set of codes designated by the vehicle manufacturer for the vehicle in order to identify the vehicle. The identification code is the unique identification number for automotive product registration throughout the entire life c...
