Hirays helps you selecting charging gun's air leak test machine

With the increasing base of new energy vehicles, the market demand for charging guns for new energy vehicle is expanding.

It is inevitable to encounter water environment when charging the car in emergency when going out, such as rain or water, and the charging gun is connected to the car and charging pile, which is exposed in the air when used, so the waterproof grade of the charging gun must be above IP67.

IP67 refers to the protection security level, in which IP refers to the abbreviation of Ingress Protection Rating, which is a level standard of dustproof and waterproof performance drafted by the International Electrotechnical Commission. IP67 waterproof refers to that the equipment has the ability of dust prevention of level 6 and waterproof of level 7. IP67 certified equipment can prevent dust from entering (overall prevention of contact and dust penetration), and can also prevent short liquid immersion (anti immersion). It can have anti immersion ability for up to 30 minutes in water up to 1 meter deep. The higher protection level is IP68. The electric appliance will sink under the specified water pressure indefinitely, which can ensure that it will not be damaged due to water immersion.

Today we share a case about the air leakage test of the charging gun.

Testing equipment: HP pioneering series air leak tester machine

Testing scheme: Due to the customer's charging gun products should reach the IP68 waterproof level, according to the structure and needs, it is recommended to use direct testing, with matching tooling and fixtures.

The testing parameters are: Input Press 30Kpa, Filling time 10s, stable 10s, testing time 5s. During the test process, if the leak exceeds 30Pa and an alarm signal is issued, it means that the air leakage of the charging gun is unqualified.
