IEC 62196 EV Plug Grounding Contacts Short-time High-current Withstand Test Equipment

IEC 62196-1 Short-time Test Current and Temperature Rising Test System Test Current 6500A

Product overview:

This test system meets the standard requirements of IEC 62196-1Ed.4CDV 2020 clause 12.3, clause 24, table 10, clause 34.2, 34.4 and 35.4., IEC 62916-2, IEC 62916-3, etc.

It is suitable for detecting the temperature rise test after the EV plug and socket pass the rated current, and assessing the heating of the surface of the electrical accessories when the load current is connected, and whether the temperature rise of the terminal meets the requirements of the standard. Also used for short-time high current withstand test for grounding contacts.

Equipment Features

The system uses self-programmed software controlled by a computer. All standard test procedures and data judgments are controlled by the system, making operation easy. It is used to assess the surface heating and electrode temperature rise of charging interfaces and electrical accessories when connected to load current, and to check if the temperature rise meets the standard requirements.
