Description

technical field [0001] The invention relates to a temperature rise test system, in particular to a test system for detecting the temperature rise characteristics of a conductive charging interface of an electric vehicle. Background technique [0002] Electric vehicles use electricity instead of oil to achieve a "zero-emission" low-carbon life, which is an important means to solve the contradiction between energy shortage and economic development. As the energy supply link for the operation of electric vehicles, the charging system is the supporting foundation of the electric vehicle industry. As the only link between the electric vehicle and the charger, the conductive charging interface is used to connect the active cable and the charging part of the electric vehicle. It consists of two parts, the charging connector and the charging socket, and undertakes the important responsibility of ensuring the safe charging process of electric vehicles and realizing the interaction b...

Problems solved by technology

In the existing detection technology, there is no good method to scientifically test the temperature rise characteristics of the charging interface. During the test, a large amount of materials and wiring need to be prepared before the test can be carried out.

At the same time, limited by the environment, the test wiring is inconvenient and the test steps are complicated, which will lead to low accuracy of the test results. In addition, the test also consumes a lot of power.

These all directly affect the final test data results
