As promised earlier this year, the upcoming face-lifted version of the 2017 Mercedes-Benz S 550 e (S 500 e in Europe) will bring a wireless charging option.

Supplier of the inductive charging system will be Qualcomm, which for plug-in hybrids, offers the 3.6 kW Qualcomm Halo unit.

Efficiency of the wireless charging is rated at 90%.

So far this year, Mercedes has sold just over 250 S 500 e in the U.S., but the expansively large, luxury model also gets a much needed internal upgrade of the battery as well for the upcoming model year.

Battery capacity moves from 8.7 kWh to 13.3 kWh (details), which should move the plug-in's real world/EPA driving range from around 12 miles (~19 km) up to 19-20 miles (30-32 km).

Of note: Mercedes states an optimistic Euro/NEDC metric of 50 km/31 miles driving range for the new S Class plug-in...which we will just go ahead and ignore

"Qualcomm Halo uses resonant magnetic induction to transfer energy, wirelessly, from a ground-based pad to another pad integrated in the vehicle. Energy is transferred quickly and safely to an automobile’s battery. Just as important, energy is transferred efficiency — Qualcomm Halo is comparable to conductive charging’s 90% efficiency rating, but Qualcomm Halo’s efficiency improves as the level of wireless charging power is turned up.

Qualcomm Halo WEVC was rigorously tested and refined in the Formula E racing series by the official FIA Formula E Qualcomm Safety Car. The lessons Qualcomm learned on racetracks around the world have led up to the consumer debut of the technology.

Qualcomm, through its subsidiary Qualcomm Technologies (QTI), already works closely with the Mercedes factory Formula One team, Mercedes AMG Petronas. QTI’s work with the team has resulted in speed, efficiency, and safety improvements using racecar data sharing over Wi-Fi."
