One. on the technology of charging gun design
The charging gun is not only connected with the electric vehicle and the charging pile, but also tied with the user's safety when charging. As an excellent charging gun enterprise, it should not only make good charging performance, but also make absolutely safe charging gun.
Charging gun in the material not only to be safe and waterproof but also durable, but also to have excellent insulation, flame retardant, high temperature resistance and other performance, before putting into production, to pass the continuous test, the performance is qualified before put into use!
A good charging gun is not only good in material selection, but also in design. The design of the handle should conform to the principle of human body mechanics. In this way, it will be very convenient to use.
Two, charging gun material selection requirements
1 mechanical insertion force test vehicles rolling test to 25 ℃ x 16 h low-temperature impact the service life of 10000 times
2 and heat-resistant properties ℃ 80 ℃ x 168 h thermal aging 168 x 1 h thermal storage test
3 UL94 flame retardant properties, V - 0. GWFI 650 ℃ or higher or850 ℃
4 electrical insulation resistance or 5 m Ω (500 vd. C) CTI 175 v or higher dielectric strength: a flashover or breakdown phenomenon is not allowed
