Abstract

The invention discloses a message detection method and apparatus. The method comprises: acquiring a charging message of interaction between a charging pile and an electric vehicle charged by using the charging pile; acquiring a preset communication protocol standard; and detecting whether the charging message meets content requirements of the preset communication protocol standard. The message detection method and apparatus solve the technical problems of low analysis efficiency and easiness for generating faults, which are caused by a complex manual message analysis process in the related arts.

Description

technical field [0001] The present invention relates to the field of new energy vehicles, in particular to a message detection method and device. Background technique [0002] Charging infrastructure is an important foundation and support for the promotion and development of new energy vehicles. In the context of the gradual opening of the charging pile and electric vehicle market, the rapid increase in the brand and number of electric vehicles will inevitably put forward higher requirements for the charging reliability and compatibility of charging facilities and services. [0003] The DC fast charging interface of electric vehicles and its CAN communication protocol refer to the national standards "GB / T20234.3-2011 Connecting Devices for Conductive Charging of Electric Vehicles Part 3: DC Charging Interface" and "GB / T27930-2011 Off-board Conductive Charging of Electric Vehicles" The communication protocol between the charger and the battery management system is designed, ...
