Non-vehicle-mounted charger protocol conformance test and message automatic analysis system thereof

Abstract

The invention discloses a non-vehicle-mounted charger protocol conformance test and a message automatic analysis system thereof. The system comprises an upper computer and a lower computer which are in communication connection. According to the method, the protocol conformance test requirements within the national standard range can be met, non-standard test cases can be added and edited at will according to the research and development and detection requirements, and the problems of insufficient test cases and conformance verification of different technical paths in the research and development and detection process at present are solved; real-time automatic analysis of communication messages in the charging process of an electric vehicle and a non-vehicle-mounted charger, actual field collection and recording of the communication messages and storage can be completed, a typical actual charging case library can be formed, and cases in the case library can be called to perform reproduction simulation test on different non-vehicle-mounted chargers; and the risk of errors of non-vehicle-mounted charger products during on-site operation can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging facility detection, in particular to a non-vehicle charger protocol consistency test and an automatic message analysis system thereof. Background technique [0002] Off-board chargers (commonly known as DC charging piles) belong to the charging infrastructure and are one of the main facilities for providing electric energy supply for electric vehicles. Charging compatibility issues and related safety issues between off-board chargers and electric vehicles have been plaguing car companies, operators and charging facility manufacturers. Communication protocol conformance testing is an effective means to reduce charging compatibility issues and related safety issues between off-board chargers and electric vehicles. In order to ensure that off-board chargers can charge different types of electric vehicles normally; at the same time, to ensure the safety of the charging process, the ...

AI Technical Summary

Problems solved by technology

[0005] The number of test cases in the national standard is limited, and it is impossible to simulate all the situations that may be encountered in the actual charging process; and some requirements in the national standard are not specific enough, leaving room for all parties to adopt various technical paths to achieve the same requirements. The current The test system cannot test the compliance of all technical paths

The current test system cannot complete the collection, recording, storage, and recurring simulation test of communication messages during the actual vehicle and pile charging process

[0006] 2. The current test system can only capture the specific communication messages required by the standard and judge the compliance of the standard, and lacks the automatic frame-by-frame real-time analysis function of the meaning of all communication messages; The problem cannot be judged, and it may also cause the system to misjudge the test cases in the standard

R&D personnel and testing personnel need to manually analyze the meaning of non-standard packets frame by frame and then find problem points. The workload is huge and the work efficiency is very low.
