TDK Corporation is the latest contender in the race for wireless charging as WiTricity announced an intellectual property license agreement with TDK.

“This licensing agreement will enable TDK to commercialize WiTricity’s patented technology to create efficient and high performance wireless charging systems for carmakers, allowing next generation electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs) to charge effortlessly by simply parking over a TDK wireless charging pad.”

TDK argues that for a long time it has been a leader in providing electronic materials and components essential to modern wireless charging systems, so having an end product in its portfolio would be win-win.

“In particular, TDK is known as the world’s leading producer of electronic components based on advanced ferrites, a vital material for harnessing magnetic fields, and has a large and rapidly growing business as a Tier 1 and Tier 2 supplier in the automotive industry. Under this IP license agreement, TDK will be able to offer wireless charging systems to carmakers for future rechargeable hybrid electric and battery electric vehicles. In addition, TDK is licensed to offer compatible automotive wireless charging sources for home, commercial, and public use.”

WiTricity CEO Alex Gruzen stated:

“There is widespread recognition that wireless charging will be central to the growth of the electric vehicle market. We are proud to help advance the market for wireless charging with such an accomplished partner as TDK.”

Everybody wants to do wireless charging thingies.

Why? Because we know how to do it and it seems kinda whiz-bang.

But what we need is CHEAP safe energy-dense batteries . . . those are hard to create.

I am excited about wireless charging. One of the few things I don’t like about my Leaf is plugging it in. Sure I don’t have to go to the gas station – once a week or so – but I have to plug my car in in 2 or 3 times a day – usually with my hands filled with I’m carrying into the house from my car.

Wireless charging makes more sense if it’s embeded in a highway lane, for long distance EV trips cross country.

Too much loss over a direct plug to justify home use. And there is that problem of no single standard…

Embedding wireless charging equipment in highways would be a massive infrastructure project.
Most countries, us included, have problems building normal roads.

A well engineered wireless charging system can have efficiencies of over 90% – certainly acceptable.
The losses compared to wired charging would be financially negligable.

And if efficiency were so important to people, there would be:
– almost no suvs
– no ices (they would have been abandoned before they became widely adopted decades ago)
– no idling (trucks, (dumb) cops, engines switched off at traffic lights and in traffic jams)
– better architecture for more natural lighting
– fewer lights and tvs left on when no-one is there

Few people ever care about efficiency.
And a few % losses would be worth it if it saved much more % losses by encouraging and easing the transition from the most inefficient drivetrain:

the ICE.

Induction lanes only need a profit model to get them built. But the single biggest roadblock is the lack of a universal wireless standard.

SAE J2954 wireless standard should be done soon.

Faster please!
