Suitable for pressure life testing of various electric vehicle charging piles, the power plug and vehicle plug with the manufacturer's recommended cable are randomly placed on the cement ground. A car tire with the same load specification of P225/75R15 is used to press the power plug or vehicle plug (tire inflation pressure 220 ± 10kPa) at a speed of (8 ± 2) km/h under a pressure of (11000 ± 500) and (5000 ± 250) N to simulate the vehicle rolling test.
