New energy vehicles can be seen everywhere in life, which has led to more items that need to be tested. This is required in relevant standards such as IEC62196-1 and IEC62752.
The drive over test is essential for the safety of new energy vehicles.
Taking into account the force value required for the drive over test required by the standard, the impact force of the tire, and the safety of the operator, we designed and manufactured this charging interface drive over test equipment. It is used to conduct vehicle drive over tests on charging vehicle power supply plugs, vehicle plugs and function boxes to determine their reliability after drive over.
The entire equipment adopts a cold-rolled steel plate protective box structure design. The surface of the box is treated with Teflon paint. The bottom of the box is covered with simulated cement floor. The rolling mechanism can simulate a car tire rolling over an object and then sliding up and down freely. The charging pile plugs bear the same pressure. The driving device drives the rolling mechanism to achieve forward and backward rolling movements. The main components are made of stainless steel and aluminum parts. (Make sure the tire is rolling over the sample under normal rolling conditions).
The device weighs 2 tons. We are responsible for installation and commissioning at the customer's site. Begin by laying the power plug and vehicle plug with the manufacturer's recommended cables loosely on the cement floor. Use a car tire with the same load as P225/75R15 to apply a rolling force of (5000±250)N or (11000N±550)N, and roll over the charging plug or plug function at a speed of (8±2)km/h. Box (tire inflation pressure 220±10)kPa. It is used to simulate and test the ability of the power supply plug or plug function box to withstand vehicle crushing damage. This equipment has a device to prevent sample movement.
