Description

Technical Field

[0001] The present invention belongs to the technical field of automobile charging gun testing, and in particular relates to automobile charging gun testing equipment. Background Art

[0002] The car charging gun is a key device for realizing the power supply of electric vehicles. It is mainly composed of a gun head, a cable and a control box. The gun head is designed according to different standards and is suitable for the charging interface of various models. The cable is responsible for power transmission, has good conductivity and insulation properties, and is available in a variety of length specifications. The control box is the core. It confirms the charging parameters by communicating with the electric vehicle. It has multiple protection devices such as overcurrent and overvoltage built-in to ensure safe and stable charging throughout the process. According to the charging method, car charging guns can be divided into two categories: AC and DC. AC charging guns have lower power and are often used for slow charging in places such as homes. DC charging guns have high power and can achieve fast charging to meet the emergency energy replenishment needs of public charging stations. The existence and continuous development of car charging guns have provided a strong guarantee for the popularization and convenient use of electric vehicles.

[0003] However, after production, automotive charging guns must undergo rigorous testing to ensure that data such as electrical performance and safety indicators meet standards. However, in actual application scenarios, charging guns are exposed to outdoor environments for a long time, facing multiple tests of wind, sun, rain, and extreme temperature changes. These complex climatic factors will not only accelerate the aging of the charging gun casing and damage the internal circuit insulation layer, but may also cause problems such as oxidation and loosening of contact parts, significantly shortening its service life. The current testing process has limitations. Most test equipment can only simulate a single or partial environmental condition, and it is difficult to fully restore the complex weather conditions faced by the charging gun in actual use. As a result, the test results deviate from the actual use scenarios, and its long-term reliability and stability in extreme environments cannot be fully evaluated, posing potential risks to charging safety and equipment maintenance.

Then the illumination lamp 20 is controlled to turn on and emit light to simulate sunlight. Its brightness and illumination time are adjusted to simulate sunlight of different intensities and durations. When a high temperature environment needs to be simulated, the heating tube 24 is controlled to start and heat up. At the same time, when a low temperature environment is simulated, the refrigeration unit 28 is controlled to start and cool the air through the refrigeration pipe rack 26. During the test, the display 5 displays the temperature and other relevant data monitored by the temperature sensor 12 in real time, which is convenient for the operator to adjust the test temperature.
