Hella, a German automotive part supplier known mainly from vehicle lighting and electronics systems, announced that, together with with Paul Vahle GmbH, it is developing wireless charging systems.

"The cooperation between Vahle and HELLA combines the expertise and experience of both companies in the field inductive charging. Based in Kamen, Germany, Vahle has 15 years of experience in contact-free energy transfer in industrial environments, while HELLA is a recognized leader in the development of electronics, software, processes and production in the auto industry."

According to Hella, wireless charging is the future as it's a more convenient and less time consuming method. Furthermore, if charging coils were embedded in streets, electric vehicles could be recharged when stopped at traffic lights or even while being driven.

Dr. Marc Rosenmayr, CEO for HELLA Electronics in North and South America stated:

"Wireless, inductive charging is a far more convenient way to recharge a vehicle's battery system. The driver only needs to stop or drive over a charging unit or network to activate the process. As wireless charging has become more available and easy to use, it also might allow automakers to reduce battery size and weight on electric and hybrid electric vehicles."

But still there are some technological and infrastructure challenges (above and beyond the lack of a wireless charging standard):

"Energy transfer over high-frequency fields that are at the heart of inductive systems, for example, cause heat to build up in metal objects which could lead to safety issues. The impact that wireless charging might have on other vehicle electronic systems such as navigation, infotainment, driver-assistance and keyless entry systems also will need to be studied."
