UL has announced that a wireless electric vehicle (EV) power transfer system has been certified to UL 2750, the Outline Of Investigation For Wireless Power Transfer Equipment For Electric Vehicles.
Lumen Group, an integrator of automotive systems, became the first organization to certify to UL 2750 for their Lumen Freedom wireless power transfer (WPT) system. Lumen Group worked with UL’s engineers and laboratory technicians globally on the safety and performance of the wireless charging equipment including the power source, the ground pad assembly and the attached vehicle assembly, ultimately achieving UL 2750 for its WPT system.
UL 2750 covers wireless power transfer equipment for transferring power to an EV, including:
- The power source for wireless power transfer
- A ground assembly, as a minimum
- The mating vehicle assembly
This equipment is intended to have a maximum rated input voltage to the power source of 600 volts AC, 50 or 60 hertz.
