UL 2251 Electric Vehicles Plugs Endurance Test Equipment Load Tester

Product information:

The test equipment is used to verify whether electrical accessories such as electric vehicle charging interfaces, industrial plugs, socket-outlets and couplers can withstand the mechanical, electrical and thermal stresses that occurred during normal operation without excessive wear or other harmful effects.

The servo motor drives the mechanism to make the test samples repeat insertion and withdrawal actions. An external load can be used for the breaking capacity test. The power on / off time, test speed, stroke, and angle can all be preset on the touch screen.

Applied standard & clauses:

IEC62196-1: 2014 “Plug, socket-outlets, vehicle connectors and vehicle inlets–Conductive charging of electric vehicle-Part1: General requirements” clause 22 and clause 23

IEC60309-1: 2012 “Plug, socket-outlets and couplers for industrial purposes–Part1: General requirements” clause 20 and clause 21

UL 2251-CLAUSE 45

22.2 The test position shall be horizontal or, if not possible, as in normal use.

The plug or vehicle connector is inserted into and withdrawn from the socket-outlet or vehicle

inlet at a rate of 7.5 strokes per minute, or at the rate recommended by the manufacturer,

whichever is less. The speed of insertion and separation of the plug or vehicle connector shall

be (0,8 ± 0,1) m/s.

The speed of insertion may differ according to manufacturer’s recommendation.

The measurement of speed is made by recording the interval of time between insertion or

separation of the main contacts and the insertion or separation of the protective earthing

contact, relative to the distance.

Electrical contacts shall be maintained for no more than 4 s and no less than 2 s.

The movement(s) of a plug or vehicle connector during insertion into the mating accessory

may be more complex than a single linear movement. At the manufacturer’s option, the test

may be made with the insertion and withdrawal made manually or by machine. The movement

may be limited to provide adequate separation of the mating contacts.
