CARS.COM — The refreshed 2017 Mercedes-Benz S550e plug-in hybrid will let you go cordless with the option of wireless charging technology.

The wireless electric vehicle charging system will use the Halo charging technology developed by Qualcomm and will be produced for the car under license by an unnamed automotive electronics supplier.

The resonant magnetic induction charging system involves a wired charging pad on the garage floor or parking spot and a corresponding pad fitted underneath the car. When the car is driven over it and the pads are lined up, electricity is transferred electromagnetically to charge the car’s battery. Wireless charging systems are widely used for small devices, such as phones and electric toothbrushes. But while there are some aftermarket systems for cars, this will be the first offered as a factory option for an electrified car, Qualcomm says.

The company says the power transfer efficiency of its Halo system is comparable to conductive charging’s 90 percent rating and that efficiency rises as power increases. It did not specify how long it would take with the system to charge the S550e’s 8.7-kilowatt-hour battery. Qualcomm says that while the 3.6-kilowatt system for the S550e is “perfectly adequate” for charging the smaller battery of a plug-in hybrid, it would require “double or even triple” that to charge a full electric vehicle with a 30- to 40-kwh battery “in a reasonable amount of time.” Longer-range EVs have even bigger batteries; the coming Chevrolet Bolt’s battery pack is 60 kwh and a Tesla Model S can be had with up to a 100-kwh battery.

Pricing for the system was not announced; the base 2017 S550e starts at $97,525 with destination.

Mercedes’ parent Daimler and Qualcomm have been working together on such technology since 2015. And Qualcomm has been showing off the technology on the Formula E electric car racing circuit, charging the BMW i8 safety cars used for the races.
