North America

EV charging and BMS test systems for North America.

Test the charging station, vehicle or battery-management system against defined interfaces and operating conditions. Local commercial access in Michigan connects your team with the configured test setup and the relevant engineering specialists.

Test area and evidence

Test areaWhat to define or record
Regional accesscomemso North America Corporation. Farmington Hills, Michigan.
Telephone+1 (248) 970-2420. America/Detroit, Eastern Time.
Charging interfacesAgree SAE J1772, J3400/NACS, CCS, DUT role and protocol scope.
Safety and installationIdentify applicable UL standards, adopted NEC edition and local authority requirements.

The named system configuration, interfaces and released libraries determine coverage. Product certification, installation approval and local code compliance are separate decisions.

Questions about this test scope

Where is the regional office?

32000 Northwestern Highway, Suite 150, Farmington Hills, MI 48334, United States.

Which time zone should I enter for a demo?

Enter your local time zone and two or three available windows. The office is in America/Detroit; the demo appointment is agreed after your request.

Does a NACS interface imply UL certification?

No. Interface support and certification of charging equipment are separate. Agree the certification route with the responsible laboratory or authority.
