EV Charger Testing & Commissioning

Testing and commissioning of AC and DC EV chargers before they go into service, and fault finding and periodic testing on chargers already in use.

Commissioning tests

• Insulation resistance and earth continuity testing
• Earth fault loop impedance verification
• RCD and DC fault current protection testing
• Functional testing with an EV simulator to IEC 61851
• Charging session verification at rated power
• Communication and OCPP connection checks
• Commissioning report and handover documentation

Service and maintenance

• Fault diagnosis and repair
• Periodic safety and performance testing
• Connector, cable and enclosure inspection
• Firmware updates and configuration

A charger that powers on is not a charger that is safe

An EV charger can light up and start a session while its earth fault protection has never been properly checked. Because a vehicle stays connected for hours, often unattended, protection that works on paper but not in practice is a real risk. We test every protective function with calibrated equipment and a vehicle simulator before a charger is handed over.
