IEC62196-1:2014 Charging interface vehicle rolling test machine
Equipment Introduction:
This equipment puts the power supply plug and the vehicle plug with
the cable recommended by the manufacturer on the concrete floor
randomly, and applies (5000±250)N or (11000N±550)N to the car tires
of the same load with the specification of P225/75R15. The pressure
is rolled over the charging plug or plug function box (tire
inflation pressure 2.2±0.1) Pa at a speed of (8±2)km/h to simulate
and test the ability of the power plug or plug function box to
withstand vehicle crushing damage .
It is used to carry out vehicle rolling test on the power supply
plug and the vehicle plug of the charging vehicle to determine its
reliability after being compressed.
Test Principle:
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.
Technical Parameters:
| Test Station | Single |
| Electrical Control Method | PLC intelligent integrated control, color humanized touch interface
operation |
| Drive Mode | Motor driven |
| Load Carrying | A. Crushing force (5000±250) N B. Crushing force (11000±550) N |
| Drive Over Speed | (8±2) km/h for (5000±250) N test, we limit the speed to be max. 7
km/h, as above 7 km/h will loss the motor rapidly 0~5 km/h can be set for (11000±550) N test, suggest to set 2 km/h |
| Roll Over Method | The linear motor module is used to drive the automotive tire to
simulate the front and rear reciprocating rolling motion (to
simulate the damage caused by the accidental rolling to the vehicle
connector or plug during the forward or reverse moving of the car
in the real scene) |
| Crushing Force Loading | Using supplementary weights to apply the crushing force |
| Drive Over Tire | ST225 / 75R15 2 pcs, one for (5000±250) N test, the other for (11000±550) N test |
| Air Pressure of Tire | (2.2±0.1) bar |
| Test Floor | A bottom plate with cement/ concrete surface |
| Lifting Device | Electric hoist |
| Tire Installation | Electric hoist lifting and restructuring |
| Driveover Speed | Can be display and set on the touch screen |
| Shock Absorption Method | Damping spring |
Equipment Structure:
This equipment adopts servo motor to control speed, Mitsubishi PLC
controller, with high control precision.
