Case Study | EV Charging Station Pull & Torque Testing Equipment

Project Overview
In response to the growing demand for safe and reliable EV charging stations, our team developed an advanced Pull & Torque Testing Equipment for AC and DC charging stations. Designed according to IEC 61851-23:2023 clause 11.6.102, this solution helps clients ensure their charging products meet international safety standards.

Tested Samples

• Electric vehicle AC and DC charging stations

• Cord anchorage and cable fixing devices of charging guns  

•  

• 

Testing Goals
The flexible cord anchorage must relieve conductors at terminals from pulling force and torque. This equipment accurately tests the ability of cord anchorage and cable fixing mechanisms to withstand specified tensile forces and torque, guaranteeing long-term product safety and reliability.

Testing Principle

• Pulling Force: Applied via a motor-driven eccentric wheel with adjustable speed, ensuring precise and repeatable force. Duration is monitored automatically.

• Torque: Applied using a motor-driven tray lifting a weight, which automatically resets after the test duration.

Key Features

• PLC-controlled automated operation for ease of use

• Stable pulling force via weight system; torque generated through weights and torque arm

• Customizable number of cycles and torque test duration; equipment stops automatically

• Compatible with charging guns of different cable lengths

• Ensures maximum displacement of connector cables stays within standard limits

Client Benefits

• Improved product testing efficiency and reliability

• Supports R&D and production quality control

• Ensures compliance with IEC standards for international markets
