As the base of new energy vehicles continues to increase, the market demand for new energy vehicle charging guns is expanding.

When you go out and charge your car in an emergency, you will inevitably encounter a watery environment, such as rain or stagnant water. The charging gun is connected to the car and the charging pile and is exposed to the air when used. Therefore, the waterproof level of the charging gun must be IP67 or above.

IP67 refers to the protection safety level, where IP refers to the abbreviation of Ingress Protection Rating, which is a dustproof and waterproof performance level standard drafted by the International Electrotechnical Commission.IP67 waterproof means that the device has level 6 dustproof and level 7 waterproof capabilities.IP67-certified equipment can protect against dust ingress (overall protection against contact and dust penetration), and can also protect against short-term liquid immersion (immersion resistance). It can be immersion resistant in water up to 1 meter deep for up to 30 minutes.The highest protection level is IP68, which means the appliance can be submerged indefinitely under specified water pressure to ensure no damage due to water immersion.

What we share today is aboutCharging gun air tightness testcase.

Testing equipment: HP development seriesAir tightness tester。

Inspection plan: Since the customer's charging gun product must reach the IP68 waterproof level, according to the structure and needs, it is recommended to use the direct inspection method during inspection, with matching tooling and fixtures.

The detection parameters are: air intake 30Kpa, time 10s, voltage stabilization 10s, test time 5s.During the detection process, if the leakage value exceeds 30pa and an alarm signal is issued, it means that the air tightness of the charging gun is unqualified.
