German lighting and electronics supplier Hella KGaA Hueck & Co. is collaborating with inductive charging system maker Paul Vahle GmbH to develop a wireless charging system for electric and hybrid vehicles.

The companies have offered no details about their collaboration or timetable for developing a commercially available system. They enter the nascent wireless charging market well behind other developers, including Qualcomm Inc., whose Halo system is undergoing field tests now.

Inductive charging offers obvious convenience for EV owners, especially in bad weather. Instead of plugging in, drivers simply park their properly equipped vehicle above an in-ground or on-ground charging plate. The system then transfers power from plate to car through a field created by the charging pad.

Hella says its development program will include evaluation of such issues as interference with other vehicle electronics and the tendency of high-frequency inductive eddy fields to heat up nearby metal objects.
