EV Plug & Connector Drive-Over Test Equipment IEC 62196-1 EV Charger Durability Testing

EV Plug & Connector Drive-Over Test Equipment IEC 62196-1 EV Charger Durability Testing

Overview:

The Vehicle Drive-Over Testing Apparatus is specifically designed to assess the resistance of EV plugs and connectors against accidental vehicle crushing. This ensures that charging accessories meet IEC 62196-1:2022 requirements for durability and safety, providing manufacturers with reliable test data to validate product compliance.

The system realistically simulates the situation where a charging connector is left on the ground and driven over by a vehicle tire. By applying a controlled force and speed, it evaluates whether the accessory can withstand damage without compromising safety or functionality.

Purpose and function:

Safety and durability testing: The main purpose is to ensure that EV charging plugs and connectors can withstand damage if a vehicle drives over them. This is a crucial safety test required by international standards like IEC 62196-1.

Realistic simulation: The apparatus is designed to accurately simulate the forces and motion of a real automobile tire rolling over the component. This often involves a reciprocating rolling motion to replicate both forward and backward movements.

Standard compliance: Manufacturers use this equipment to test that their products comply with the specific requirements and parameters of automotive and electrical safety standards.

Key components and features:

Test tire and rim: The apparatus uses a standard automotive tire (e.g., P225/75R15) mounted on a steel rim. The tire's pressure is set to a specific standard value.

Crushing force mechanism: The system applies a specific crushing force to the component, typically 5000 N for cars and 11000 N for larger vehicles. A precision force sensor and adjustable weights ensure the accuracy of the applied force.

Motor and drive system: A servo motor combined with heavy-duty rails and rollers drives the test tire to simulate the vehicle's motion. This allows for precise control of the speed and direction of the roll-over.

Component fixture: The apparatus includes a jig or sliding device to securely hold the component being tested. This prevents it from moving significantly during the test while allowing it to be oriented in different positions to simulate how it might land.

Concrete test floor: The test item is placed on a concrete or cement-like surface, replicating the environment of a real-world parking area or garage.

Control system: A Programmable Logic Controller (PLC) with a human-machine interface (touch screen) allows operators to control and monitor the test parameters, such as speed and force.
