The invention discloses a temperature rise test instrument and a test method for a large current charging connector. The control input end of an intelligent current rise device in the temperature rise test instrument is connected with the current control end of a master controller, the output end of the intelligent current rise device is connected with the current input end of the charging connector to be tested, thermocouples are distributed on various positions on the outer surface of and inside the charging connector to be tested and are connected with a temperature routing inspection device, and the temperature routing inspection device is connected with the master controller. Changes of large current flowing through the charging connector can be simulated by the temperature rise test instrument and the test method for the large current charging connector, by analyzing corresponding acquired parameters, the temperature rise capacity and the external allowed temperature of the charging connector are comprehensively researched and evaluated, human factors existing in the temperature rise test process can be eliminated, in a long-time temperature rise test process, relevant current parameters are set through the master controller for automatic detection, working efficiency is improved, the concept is ingenuous, and the temperature rise test instrument and the test method for the large current charging connector have good application prospects.
Description
technical field [0001] The invention relates to a temperature rise tester and a test method for a large-current charging connector, belonging to the technical field of temperature detection. Background technique [0002] With the continuous and rapid development of the world economy, the resulting energy shortage and environmental pollution will become more prominent. New energy vehicles, as zero-pollution, zero-emission, high-energy-efficiency, and low-energy vehicles, undertake the important task of energy conservation and emission reduction. It will eventually benefit production, life and the ecological environment. The charging connector of electric vehicles is used for the charging connection between electric vehicles and power sources. It is one of the key devices in the conductive charging system of electric vehicles. Reliable operation will have an immediate impact. [0003] We know that the charging current flowing through the connector during the charging process ...
