With the growth of electric vehicles and their associated technology ecosystem, Eurofins MET Labs is seeing higher levels of testing and certification in this industry. Following is a summary of the standards that apply to electric vehicles (EVs) and electric vehicle supply equipment (EVSE).
EV UL Safety Standards:
UL 2202 EV Charging System Equipment
UL 2251 Standard for Plugs, Receptacles, and Couplers for Electric Vehicles
UL 2231-1 and UL 2231-2 Personnel Protection Systems for EV Supply Circuits
UL Subject 2580 Batteries for Use In Electric Vehicles
UL Subject 2594 EV Supply Equipment
EV International (IEC) Standards:
IEC 61851 Electric Vehicle Conductive Charging System
IEC 61982 Secondary Batteries for the Propulsion of Electric Road Vehicles – Performance and Endurance Tests
IEC 62133 Secondary Cells and Batteries Containing Alkaline or Other Non-Acid Electrolytes – Safety Requirements
IEC 62196 Plugs, Socket-Outlets, Vehicle Connectors and Inlets – Conductive Charging of EVs
EV SAE Standards:
SAE J1772 Electric Vehicle and Plug in Hybrid Electric Vehicle Conductive Charge Coupler
SAE J2293 Energy Transfer System for Electric Vehicles
SAE J2464 Electric and Hybrid Electric Vehicle Rechargeable Energy Storage System (RESS) Safety and Abuse Testing
SAE J2894 Power Quality Requirements for Plug-In Electric Vehicle Chargers
SAE J2929 Electric and Hybrid Vehicle Propulsion Battery System Safety Standard – Lithium-based Rechargeable Cells
The Authority Having Jurisdiction (AHJ) – often electrical code inspectors – have final say in the acceptance of equipment and electrical installations in the United States. The U.S. National Electric Code (NEC) informs the AHJ that a piece of equipment is acceptable if it has the listing mark of an approved Nationally Recognized Testing Laboratory (NRTL). In the case of EV charging systems, Article 625 indicates that all electrical materials, devices, fittings and associated equipment shall be listed or labeled.
Over 25 years ago, MET Labs became the first NRTL, and today is capable of performing testing to all major EV and EVSE standards.
