Electric Vehicle Charging Gun UL 2251 Certification-Vehicle Rolling Test

Electric vehicle charging guns need to meet the standards of UL 2251 and CSA NO. 282 and the main test items when entering North America. Among them, the vehicle rolling test of charging guns is a special test of UL 2251. Next, Anke will show you the test method and judgment basis:

Electric vehicle charging gun UL 2251 certification-vehicle crush test method:

• the charging cable includes plug and connector. The coupler is placed on the concrete floor and placed in a normal static state. It is kept in a fixed position during the test and will not move greatly during the application of force.

• the 4893N impact force was applied with a P225/75R15 conventional car tire, or an equivalent loadable tire was mounted on the steel rim and inflated to 218 ±13 kPa.

• the wheels rolled the plug, connector, coupler at 8±2 kmph.

• finally, the withstand voltage test is carried out.

  Note:

the size of the charging cable shall be consistent with the label.

• in any case, no force can be exerted on the protruding pin.

of electric vehicle charging gun UL 2251 certification-vehicle crushing test judgment basis:

during the above test, there shall be no serious cracking, fracture or deformation causing the following phenomena:

• the test finger touches the charged body;

• the shell is damaged so that the internal components are not mechanically protected or the polarity of the equipment is invalid;

• operate, operate, or install equipment in a manner that allows the user to be exposed to danger. The equipment is allowed to be inoperative after the test. The lock catch used to fix the mating device is allowed to be damaged if it does not affect the safe operation or is obviously damaged and needs to be replaced;

• the requirements of Strain relief are not met after the test;

• Spacing reduced to the minimum acceptable value;

• other evidence that may increase the risk of fire or electric shock;

• the pressure test after the rolling test failed.
