With the rapid development of electric vehicles (EVs), ensuring the safety, durability, and performance of EV charging connectors has become critical. EV charging connectors, commonly referred to as charging guns, must undergo rigorous testing to meet international standards and customer expectations. This document outlines the testing requirements for EV connectors, the equipment used, and the comprehensive solutions we offer.

Testing Requirements for EV Charging Connectors

To ensure high performance and reliability, EV charging connectors need to pass various tests covering electrical safety, mechanical durability, and environmental adaptability,etc. Below are the key testing areas and corresponding equipment:

1. Electrical Safety Testing

   • Insulation Resistance Tester: Ensures that the connector maintains adequate insulation under high voltage to prevent leakage current.

   • High Voltage Tester: Verifies the connector's capability to withstand extreme voltage conditions without failure.

2. Mechanical Durability Testing

   • Insertion and Withdrawal Life Tester: Simulates repeated plug-and-unplug cycles to assess the mechanical lifespan of the connector.

   • Tensile Strength Tester: Measures the mechanical strength of cables and connectors, ensuring robust design.

   • Drive-over Test Machine: Check whether a plug or vehicle connector shall have adequate resistance to damage from being driven over by a vehicle.

   • Cable Flexing Test machine: Simulates the flexing withstand of "mechanical strength" part of the power connection cable of the charging vehicle plug and socket during normal use.

   • Cord Anchorage Pull and Twist Test Machine: Verify the ability of charging plug and socket, and connection cable accessories to withstand specified pulling force and torque.

3. Thermal Performance Testing

   • Temperature Rise Test Equipment: Monitors heat buildup in the connector during prolonged use under load.

   • Heat Resistance Chamber: Evaluates connector performance under extreme temperature conditions.

4. Environmental Testing

   • Vibration and Shock Tester: Simulates the conditions experienced during transportation and operation to ensure connector durability.

   • Dust and Water Resistance Tester: Verifies compliance with IP ratings (e.g., IP67) for protection against environmental factors.
