UL 2594 Cla.58 EV Charging Plug Drive-Over 4893N Test Equipment

The test equipment is used to check whether a plug or vehicle connector shall have adequate resistance to damage from being driven over by a vehicle, unless it is provided with a cable management system which prevents the accessory from being left on the ground.

• IEC 62196-1: 2022 clause 33
• UL 2594:2016 clause 58

IEC 62196-1:2022 clause 33: Accessories wired with the minimum size cable of a type recommended by the manufacturer shall be placed on a concrete floor in any normal position of rest. A crushing force of (5000±250) N or (11000±550) N shall be applied by a conventional automotive tire, P225/75R15 or an equivalent tire suitable for the load, mounted on a steel rim and inflated to a pressure of (2.2±0.1) bar. The wheel is to be rolled over the vehicle connector or plug at a speed of (8±2) km/h. The accessory is to be oriented in a natural resting position before applying the force in a different direction for each sample. The accessory under test shall be held or blocked in a fixed position so that it does not move substantially during the application of the applied force. In no case is the force to be applied to the projecting pins.

UL 2594:2016 clause 58: Accessories wired with the minimum size cable of a type recommended by the manufacturer shall be placed on a concrete floor in any normal position of rest. A crushing force of 4893 N (1100 lbf) shall be applied by a conventional automotive tire, P225/75R15 or an equivalent tire suitable for the load, mounted on a steel rim and inflated to a pressure of 218±13kPa (32±2 psi). The wheel is to be rolled over the vehicle connector or plug at a speed of 8±2 kmph (5±1.25 mph). The accessory is to be oriented in a natural resting position before applying the force in a different direction for each sample. The accessory under test shall be held or blocked in a fixed position so that it does not move substantially during the application of the applied force. In no case is the force to be applied to the projecting pins.

This full set of testing equipment features a protective enclosure constructed from cold-rolled steel plates with a Teflon-coated exterior finish. Its base is fitted with simulated cement floor panels. The built-in rolling assembly replicates the free up-and-down sliding motion of vehicle tires when passing over objects, while charging pile connectors withstand corresponding load pressure. A dedicated drive unit powers the rolling mechanism to perform reciprocating rolling motions. Core structural parts are crafted from stainless steel and aluminum alloy, enabling standardized tire rolling tests on test samples under actual operating conditions.

• The equipment base is fitted with safety shields to guarantee reliable test operation. Shockproof foot pads and universal casters are installed at the bottom for effortless relocation and assembly. Heavy-duty linear slide rails ensure stable movement of the roller assembly. Equipped with high-torque motors and worm gear reducers, the unit drives the main shaft to rotate and adjust testing speed for compression and rolling tests. A sample positioning sliding structure with dedicated fixture mounts fully complies with industry testing standards.
• The load pressure regulation mechanism supports vertical height adjustment. The total test load consists of the weight of test tires, upper and lower sliding brackets plus additional counterweights, enabling accurate load simulation.
• It adopts bidirectional tire-driven operation. Forward and reverse motor rotation drives tires to roll back and forth, with test samples kept fixed in place. This design delivers highly authentic simulation of real-world vehicle tire reciprocating rolling actions for precise sample rolling performance testing.
• The control system is independently configured. The main unit adopts PLC intelligent control with intuitive touchscreen operation. Pre-reserved fixing holes and wiring ports on the base facilitate stable installation and circuit connection.

• The whole machine is equipped with a protective fence to prevent the wheels from accidentally deviating and prevent mechanical injuries to personnel
• It has a fixed mechanical crane arm, which is convenient, labor-saving and safe to load weights
• It has a leakage protection switch
• It has a motor overload protection
• It has a door lock safety protection function, and the trolley cannot move when the door is opened

• Power supply: Three phase AC480V±10%/60Hz, power 15KW
• Overall dimensions: approximately W4700*D1300*H3000mm
• Weight: approximately 2400kg
