WiTricity and Prodrive Technologies announced a joint project to develop 11 kW wireless charging system for a European carmaker, who apparently wishes to remain unknown at the moment, but of whom intends to use the new system in a 2019 model.

WiTricity will provide the technology, while Prodrive Technologies will design the whole packaging, and prepare series production of the final product.

At the same time, a 22 kW version is currently being researched which is probably the ultimate “sweet spot” for EV owners looking for peak residential charging. WiTricity also said previously that its wireless charging will be first used in a production car in 2017.

The first example of wireless technology via a mass produced EV is the Mercedes 500e/550e which offers the system in its new 2017 model this Fall

“WiTricity and Prodrive are helping enable that experience by bringing best-of-breed expertise to this new charging system’s design. WiTricity will provide its foundational magnetic resonance intellectual property, complete reference designs and consulting services to the project.

Based on the WiTricity designs, Prodrive will develop and industrialize an automotive mass market system and implement the automaker’s specific requirements. Prodrive has deep experience in the technology, engineering practices and highly automated manufacturing processes needed to supply power electronics on a Tier 1 basis to automakers. By incorporating WiTricity technology, the resulting Prodrive system will be capable of charge rates up to 11kW at high efficiency, comparable to the efficiency of today’s wired charging systems.

Energy transfer up to 22kW for automotive is also being researched. Prodrive will deliver an “end to end system,” including the components that are integrated with the vehicle to “capture” the wireless power, and the garage floor-mounted charging pad and wall box that serves as the source of the wireless power.”

Pieter Janssen, CEO and Co-founder, Prodrive Technologies said:

“We are proud to have been selected, alongside WiTricity, by one of the world’s top carmakers for this project. Our ability to deliver automotive-grade power electronics at scale, combined with WiTricity’s expertise and product offerings in wireless charging technology, creates a unique partnership that is enabling this innovative 11 kW design. We are excited to be collaborating on this project and look forward to working with WiTricity in the future, as wireless power will be a key technology in the automotive market, with industrial and medical applications as well.”

Alex Gruzen, CEO, WiTricity said:

“Wireless charging is emerging as a critical technology for automakers worldwide, particularly as autonomous vehicles become central to future product strategy. Being awarded this project by one of the world’s leading brands is a testament to our technology leadership and we’re proud to be working with Prodrive to make it happen. With Prodrive’s experience in automotive power electronics and sensors—and their extensive automated manufacturing capabilities, Prodrive is a strong partner for us in our mission to accelerate the deployment of efficient, fast and convenient wireless EV charging.”

Merc will probably continue with Qualcomm, VW will keep its efforts to designing paper models for 2020-2022, Opel has no plain idea what wireless really means, so prime suspect in Germany would be BMW. As for France Renault will probably turn to some Korean supplier but Peugeot could well be in consideration. Yeah, Audi is deep in process of trying to figure out by what margin will their couple A3 A4 be hurt once Tesla M3 hits the road. So, either Peugeot or BMW.

This statement: “a 22 kW version is currently being researched which is probably the ultimate “sweet spot” for EV owners looking for peak residential charging” seems like overkill for home use. How many times do I come home from driving 200 miles and need to go out and drive 200 more miles within an hour or two? Umm, never.

I’d like to know what car you’re driving that gets you 200 miles on 22kWh of energy.

I wants one.

Realistically, I think you’d get closer to 60-70 miles of range per hour. Maybe less…

And I know a LOT of people that have a 50+ mile round trip commute who would enjoy having a full charge an hour after getting home to allow for visiting friends/family/not having range anxiety for a potential emergency, etc.

The way I read this is that 11kw is fine for home use, as how often would you drive 200mi and then need to go out on another 200mi trip almost immediately, thus requiring a significantly higher than 11kw charger?

If/when they create the 1GW charger that is the same price, then we will just expect that. At the moment, with current technology and equipment, 11kw in the home is probably plenty good enough. I use 2.4kw daily and have never run out for my daily commute. Sure it takes 4-6 hours to charge, but do I care? No because I am asleep at that time.

A TRUE 10KW L2 home charger will more than suffice.
Of course for it to be a TRUE 10KW means it’s an NEC Derated ~13KW EVSE & Charger (~43A 240V circuit).

Needing anything more means you bought the wrong car/product.

I’ve got 3 circuits in my garage rated for 60 Amps. When/If I need/can afford a 50-AMP charger (or 3!) I’m ready. =)

I like the thought of wireless but at this point I say I’d feel more safe with wired. Its a lot less to pickup or run over as lone as the last person before you wasn’t a jerk and leaves the cable on the driveway for you to run over. Also gotta wonder how much harder it could be to find a capable electricitian to install so you could subsidize it.

Tesla use something like 1,000 smaller capacity batteries to power their cars? Would a high power wireless charger be possible using lots of low power wi-fi signals that aggregate into a high power charger?

Just imagine each Tesla battery incorporated a wireless charger and picked up the signal directly from the low power charger system directly under it.

Seems to me we always go for a single high capacity system that becomes harder to do rather than looking at simpler options on a massive scale. Tesla battery and performance points me to this type of solution, but I’m not technical this way, so maybe interference or other limiting factors make this impossible to do.
