Waterproof level test of new energy vehicle charger

With the maturity of various technologies of new energy vehicles and various preferential policies of the state for new energy vehicles, more people are more inclined to buy new energy vehicles. New energy vehicles take electric energy as the power source, realizing the purpose of energy conservation, emission reduction and environmental protection. However, in general, new energy vehicles are charged outdoors, which requires that the charging accessories of new energy vehicles must have IP67 or above waterproof grade. New energy vehicle charging accessories include new energy vehicle charging plug, car charging gun, charging gun connector, car charging pile, etc. If these charging accessories are not waterproof, there may be a risk of leakage and electric shock. Therefore, after the production of new energy charging accessories, the waterproof test should be carried out on the product to ensure the safe use of users. Then how to do the airtightness waterproof test of new energy vehicle charging accessories?

New energy vehicle charging accessories air tightness waterproof testing is to use compressed air as a test medium, the compressed air is filled into the inside of the product (the product has a vent outside) or the mold (the product has no obvious vent). Through the internal pressure change of the product or the internal pressure change of the customized mold, the product is detected whether there is leakage and the air tightness and waterproof test results of the new energy vehicle charging accessories are given. New energy vehicle charging accessories airtight waterproof testing equipment can be different according to the different product and waterproof level requirements, can be in
Adjust different test pressures in the range of 0.05MPa to 0.50MPa. For example, many products that need to be tested with IP67 waterproof grade, the corresponding test pressure is 10.5KPa (which can be adjusted appropriately according to the product). If the waterproof level required for the new energy vehicle charging accessories is IP68, according to the characteristics of the product, the test pressure is greater than 10.5KPa. The parameters of different new energy vehicle charging accessories are mainly set according to customer requirements and product characteristics, and the test pressure of car charging gun, car charging plug, car charging gun connector, etc. used in the new energy vehicle charging accessories air tightness waterproof test is 30kpa, 100kpa, 25kpa respectively. And the test time will vary depending on the test product, some products have a relatively large internal space, and the use of low pressure so the inflation time is very long. Although some test products are large, the test pressure is large, and the inflation time will be correspondingly shorter.
