WiTricity Collaborating with Nissan on Wireless Charging for Electric Vehicles

WiTricity Corporation

WiTricity announced collaboration with Nissan on wireless charging.

There is no details on the project, but we can assume that WiTricity could be the supplier of the system, or at least will be licensing its technology to Nissan, when the commercialization of new SAE J2954 wireless charging standard begins.

We can also assume because of this deal that the “new” LEAF will either arrive with wireless charging as an option, or it is soon to be added.

WiTricity and Nissan are collaborating to drive adoption of wireless EV charging systems.

Factory option of 3.7 kW, 7.7 kW (or 11 kW arriving in 2018) wireless charging for anyone?

“With sales of electric vehicles growing rapidly, carmakers are now very focused on streamlining the EV charging experience. The WiTricity DRIVE wireless charging system allows for a charging pad on or under the ground that uses WiTricity’s patented magnetic resonance technology to send energy to the vehicle parked above it, requiring no cables or moving parts. The DRIVE system has industry-leading efficiency and charge rates, and is capable of charging all types of vehicles ranging from low ground clearance sports cars to high ground clearance SUVs.

Nissan, together with other carmakers, has recognized that interoperability is critical for simplifying the EV charging experience and adoption of EVs more broadly. This means ensuring car owners they can charge their vehicles at any station regardless of vehicle size and type. WiTricity and Nissan are collaborating to ensure that wireless charging systems will provide the high degree of interoperability, ease of use, and high efficiency that consumers expect.”

Kazuo Yajima, Alliance Global Director of the EV and HEV Engineering Division of Nissan said:

“Nissan believes in the potential of wireless charging to help advance widespread acceptance of EV motoring. We are very pleased to be working with a technology expert such as WiTricity to advance the state of the art for interoperability, efficiency, and user friendliness.”

Alex Gruzen, CEO, WiTricity said:

“WiTricity is partnering with Nissan to catalyze wireless charging in the EV market and move the industry forward to an interoperable future. In order for us to realize a future of transportation that is electrified, shared and autonomous, we need a wireless charging solution that works for all vehicles. We’re excited to continue working with Nissan as we march toward a global wireless charging ecosystem.”

    Great idea, some really like this feature despite the efficiency so it’s awesome to have a factory option…Also as it becomes more popular the efficiency can only improve…

  2. SparkEV says:

    More crap in the air…

    1. Nick says:

      You’re referring to magnetic fields?

      1. SparkEV says:

        EM fields. When you have alternating magnetic field, it will also result in electric field. Since nothing is 100% linear, there will be harmonics.

    When they can be mounted flush with the garage floor, I’ll be interested. I use my garage for too many other things to have two (or three) speed bumps in the middle to trip over.

    1. DangerHV says:

      John, in most cases you should be able to have the transmitting plate flush mounted in your garage with a slot for the cable. It would need to stay within the max distance allowed to the receiver on the car.

      1. DangerHV says:

        From WiTricity’s website:
        “… capable of on-ground and in-ground installation.” And the range of distances are listed between 10-25 cm (~4-10″) but it’s not very clear if efficiency suffers at the higher distances.
        Interested now? Here’s what I’m reading:

        Not so with my Plugless System.
        Not so with any systems I’ve seen, including WiTricity.
        If they could be flush, they would show it off as such but it’s not the case.
        My Plugless’s sweet spot seems to be at 4 inches between plates.

          I stand corrected by DangerHV’s post.
          Seems like WPT_2 can be at 4 to 8 inches clearance so it could be flush with the floor.
          Nice.

          1. DangerHV says:

            Thanks for the link, Driverguy. I’m very interested in this kind of info and will be studying it carefully.

  4. Brenno says:

    I think this technology will eventually make it, but probably not as fast as you think. Pluggin in after all is not that big a task! Public car parks and the like this could have great applications, as well as electric highways etc although i feel the technology will take a while to develop.

    in the mean time plugging in is cheap & easy.

  5. Bill Howland says:

    With appologies to those suffering from arthritis, for most of us this is a very small benefit.

    Nissan seems to love fooling with this kind of thing, besides Hydrogen Power, and the Vehicle to Grid stuff – to my mind all of very limited usefulness. The thing that would really benefit every Nissan ev buyer would be a larger, longer lived battery.

    Of course, there are 2 rather elusive vehicles the readers here are still waiting for. It will be interesting to see who comes out with something REAL first.

    I already do all the V2Home stuff I need to do with my 2- VOltec EV’s. And I didn’t need a huge research budget to successfully do it either. Harbor Junk Tools designed and assembled the “Chicago Electric” inverters for me.

    I get a laugh out of their tradenames: the pneumatic stuff is “Central Pneumatic”, and the electric is “Chicago Electric”.

    Of course, the REAL expensive quality tools company is “Chicago Pneumatic”, but they hope that most homeowners forget the exact name, thinking they’re actually getting something valuable.

    But the cheap chinese inverters do work pretty well for the price.

      If you don’t have a garage (or don’t park in a garage), wireless would prevent having to deal w/a wet/dirty/snowy cable. Or one covered in ice sometimes. It also would prevent forgetting to plug in (I did that yesterday and had to drive around on gas).

      I agree it would also lead to more sales. A few people I’ve talked to about EVs didn’t like the idea of having to unplug & plug in every day. I explained how this was easier than going to a gas station, but it falls on deaf ears.

  6. Priusmaniac says:

    Very bizarre to have car producers, that by definition are systems that are moving and have moving parts, showing such an aversion of moving parts. It is good to avoid failure possibility of excessive moving parts, like with ICE, but in this case two small automated pantographs under the car could do a real wonder like 100% efficiency and no MF at all. That I know of, wipers are mechanical, electric motors are mechanical, Model S door handles are mechanical, opening roof is mechanical, side mirror are mechanical, windows are mechanical. There are many very efficient mechanical systems in a car and avoiding mechanical pantographs for automated charging is simply a mistake considering all the advantages that can bring. It should at least be tested as a real possibility and let the customers chose instead of forcing wireless and its associated losses, risks and power limitations.
