As new energy vehicle technology matures and the state supports new energy vehicles, more people are beginning to choose to buy new energy vehicles.New energy vehicles use electricity as the power source and are therefore more environmentally friendly.Although the use of electricity is environmentally friendly, during the charging process of the car, each charging accessory of the car needs to be waterproof.
Because when charging new energy vehicles, it is usually done outdoors.Therefore, charging accessories for new energy vehicles need to have an IP67 waterproof rating.: Such as new energy vehicle charging plugs, car charging guns, and car charging piles.If these charging accessories do not have the corresponding waterproof level, there may be a risk of leakage or electric shock.Therefore, after manufacturers produce new energy charging accessories, they will conduct waterproof testing on the products to ensure safe use by users.The mainstream waterproof testing method currently on the market is the air tightness testing method.

Air tightness testingIt uses compressed air as the medium to fill the compressed air into the inside of the product or the mold.Determine whether there is a leak in the product through changes in the internal air pressure of the product.At the same time, different test pressures can be adjusted according to different products and different waterproof level requirements.For example, for many IP67 waterproof products, the corresponding test pressure is 10.5KPA.If the product's required waterproof level is IP68, set a test pressure greater than 10.5KPA based on the pressure the product can withstand.
For new energy auto parts, the general waterproof level must reach IP67 and IP68, and the test pressures are also different. They are mainly set according to customer requirements and product characteristics.Hirays Technology has tested the waterproof performance of many new energy automobile accessories.For example, the test pressures used for car charging guns, car charging plugs, and car charging piles are 30kpa, 100kpa, and 25kpa respectively. The test time will also vary depending on the product being tested. Some products have a larger internal space and require a longer inflation time.Although some test products are large, the test pressure is very high and the inflation time is very fast.
