Toyota invests in WiTricity for wireless car charging

General

These days when we think of wireless charging we think about using an accessory for our cell phones. Not long from now we may be using the same tech to power our electric vehicles. According to CNET, Toyota has invested in a company called WiTricity that, until now, has developed wireless charging solutions specifically for portable electronics. In a recent statement Toyota said that it “believes that resonance wireless charging is suitable for automobiles and aims for its early practical use.” Using magnetic near-field, WiTricity could potentially offer a wireless charging solution for cars, too. We’re imagining a future where, instead of pulling up to the pump, or plugging your electric car into an outlet, you simply need to drive into your garage to begin charging. “WiTricity power sources and capture devices are specially designed magnetic resonators that efficiently transfer power over large distances via the magnetic near-field. These proprietary source and device designs and the electronic systems that control them support efficient energy transfer over distances that are many times the size of the sources/devices themselves,” the firm said. Other companies, like HaloIPT, also offer wireless car-charging solutions, but this is the first we’ve heard of a major car manufacturer getting on board. Read

    Wouldn’t it be great if they put resonance coils in the roads or at stoplights so you could charge while driving

      No kidding. That’s what these companies aren’t getting. I do more than drive a couple miles to work, shopping, errands, visiting family, plus a 40 mile road trip would just be lame. I don’t have an issue plugging a car in but unless I can take my garage with me or the batteries start hold a lot more charge, these cars are useless to me.

        I think in 5 years we are going to be able to drive over 200km (124 miles) without a recharge. The Tesla Roadstercan travel 244 miles on a single charge, and it costs a little over $100000. That price is going to go way down in the next years, not to mention consumer vehicles won’t have to focus as much on performance as the Roadster, drastically driving down the price.

        The real issue lies for really long trips – currently my family is traveling over 2000 km (1200 miles) to Florida by car. To make this possible with an EV, there have to be an abundant amount of battery swap stations. Until this infrastructure is created, EVs will only be used for city driving (over 90% of people don`t drive more than 50km a day anyways, according to stats).

        Ever hear of the 15 minute charge stations?

        No such thing and would be impossible for a battery of the Tesla’s size. Even if it was possible, it would ruin the battery.

    “WiTricity power sources and capture devices are specially designed magnetic resonators that efficiently transfer power over large distances via the magnetic near-field.” — This is indeed the future.

    This kind of innovation would be great news especially to those people with cars and then they have to plug something so that their phones can be charged. But this wireless charging should be available inside the car too! What’s the point of having these magnetic fields when, if I understood the article correctly, all the witricity can only be available in garages?

    This is totally awesome. My garage can charge my car, parking garages could charge your car if you’re out or at work, you could even have premium parking spots with ressonance coils. awesome. can’t wait for implementation.

    It’s amazing how many people post things like “I need to drive 80 miles each way to work this car is useless to me why the hell would they even make it” or “this doesn’t work for me and I’m think I represent the average driver”
    No, you don’t represent the average driver and if a 100 mile EV doesn’t work for you, DON’T buy it. An extended cab GMC Sierra pick up doesn’t work for me so I didn’t buy one, but I’m not telling anyone that it doesn’t work for them or calling GM idiots for building them. The fact is, a 100 mile EV will work perfectly well for a huge percentage of the population, especially households with more than one vehicle which accounts for the vast majority of the US population.
    Plus, while 100 miles seems to be the target right now for these cars, it won’t be in the near future, but to get to the 200 and 300 mile per charge EV’s we need to start at 100 miles and allow the technology to advance as all technologies do.
