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.”

Press Releases about charging technology that fail to mention kW charging-rate, or a MPH (kPH) charging-rate are just blowing smoke. If they are at all serious, they will have some minimal and targeted goals for their technology.

The graphic labeled “Paul Vahle demo conversion” is neither a demo vehicle, nor a conversion. It is a simulated mockup.

It will be interesting to hear their proposed business models for installing wireless charging infrastructure and billing? … regarding “electric vehicles could be recharged when stopped at traffic lights or even while being driven”.

If you read German you can probably find more details on their home websites.
It seems rather harsh to criticise a press release in what is for them a foreign country and language for a lack of full technical details.

No detail in the five languages they have

Inductive charging may be a good way of Park & Forget recharge, but like Elon Musk stated, Tesla would then prefer a secured contact based system, even if they have no intent on that right now.
Basically the same as a Roomba vacuum cleaner is doing but then applied to a Model S. Think to secured contacts on a bumper on the ground to avoid water and a kind of plastic brush that avoid access to the contacts once the car is over it ready to transfer order of charge to a security checking charger unit. In the end of this EV tech evolution we are going to need this anyway if we want to achieve the megawatt level hypercharge that can allow a 5 minute fill up.
