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.”

    What is the efficiency rating of a hard wired plug?

    Seems like a nice overall improvement of the car. Hoping for more in the next release. I really think 40 miles or so should be the minimum goal for a PHEV but do get that bigger cars will need bigger batteries to get there.

      Efficiency of a wired plug is over 98%.

    I’m waiting until the wireless hardware claims to be compatible with the forthcoming SAE J2954 wireless standard before I buy any hardware and go through the trouble of installing it. So, Qualcomm and Plugless/Evatran, when do you expect to start to be able to offer J2954 compatibility?

    Nice to see the battery size get bigger. It is still too small but at least it is an improvement.

    ” Euro/NEDC metric of 50 km/31 miles driving range”

    I think this NEDC range is whats needed to qualify for the EV incentives in China. Which means that will be the range target for other luxury auto manufacturers for plug-in hybrids as well.

    If the former 8.7 khW battery is now 13.3 kWh at the same price this means a 35% cheaper battery price. Or you can say that you get nearly 1.5 times the battery for the same price.

    If the price drops another 35% and the battery price still stays the same we get to 20.3kWh and 28 miles (45km) AER.

  6. Everything published made a lot of sense. However, what about this?

    what if you were to create a killer headline? I mean, I don’t
    wish to tell you how to run your website, but suppose you added a post title
    to possibly get folk’s attention? I mean Longer Range 2017 Mercedes-Benz S550e
    To Get Optional Wireless Charging is a little plain. You might peek at Yahoo’s
    front page and watch how they create article headlines to get
    viewers interested. You might try adding a video
    or a related picture or two to grab people excited about what
    you’ve got to say. Just my opinion, it might bring
    your posts a little bit more interesting.
