Wireless EV charging is still a fledgling technology, but that doesn't mean it's reserved for expensive cars alone.
Kia announced today that it has been hard at work on wireless fast-charging technology for the past three years. The project is a joint effort with Mojo Mobility and the Department of Energy's Office of Energy Efficiency and Renewable Energy. It relied on a fleet of , currently the only electric car the Korean manufacturer has on sale.
Kia's wireless charging solution provides more than 10 kilowatts of juice to a vehicle with a grid-to-vehicle efficiency rate of 85 percent. Kia also noted that its wireless charger doesn't require spot-on parking precision. Even if it's misaligned slightly, it will still work efficiently enough.
Wireless EV charging works just like it does on your phone. There's a transmitter coil built into a base, and a receiver coil built into the vehicle. When the two coils line up, an electromagnetic field allows the transfer of energy from transmitter to receiver. As with phones, some of the energy is lost as it's transmitted from charger to vehicle, which is why automakers and research labs are working to improve efficiency as much as possible.
Sadly, Kia says there is no current plan to bring its system to production for consumers. That said, it hasn't ruled out doing something similar in the future.
We've seen higher output and efficiency rates, but BMW has for its 530e plug-in hybrid, but output is lower at 3.2 kW.was just a proof-of-concept build.
Other companies believe wireless charging is the way forward, albeit with different ways of achieving the same goal. Continental would like to Qualcomm wants to , so that EVs can receive some charge as they move along.so that EVs gain a bit of charge here and there throughout the day.
