Mercedes To Offer Wireless Charging From 2017, DC Combo Fast Charging In 2018
Starting next year, Mercedes-Benz has announced that wireless charging options will be offered on its plug-in vehicles.
The first model to offer inductive charing will be the face-lifted 2017 edition of the Mercedes-Benz S 500 e, which also gets a battery bump up to 13.3 kWh and a revised 50+ km/31 mile NEDC range (perhaps ~20 miles/32 km real world/EPA).
Mercedes’ 3.6 kW wireless charging station is designed for home use, and will charge at nearly 90% efficiency. It certainly isn’t the fastest unit, but still ideal for short range, plug-in hybrid applications.
“One of the next steps on the road to the perfect electric vehicle and plug-in-hybrid is wireless charging. Inductive charging makes handling these vehicles even more convenient. Mercedes-Benz has been testing the contactless charging technology since 2015 with a test fleet of the current S 500 e. From 2017 the technology should be ready: with the facelift model of the S 500 e, the availability of an inductive charging system as an optional extra is planned, in addition to cable-connected charging. With this innovative technology, the electrical energy is contactlessly and safely transmitted via a magnetic field.
The system is comprised of two components: a secondary coil in the vehicle floor and a base plate with integrated primary coil. This is placed on the garage floor, for example, or in a protected area in front of a carport. Via a display message in the cockpit the driver can see whether the vehicle is in the tolerance range over the charging station. As soon as the charging position has been reached, charging automatically begins and is constantly monitored by the system. The electrical energy is transmitted contactlessly, without a charging cable, at a power output of up to 3.6 kW. With an efficiency rate of almost 90 percent, the high-voltage battery can be efficiently, conveniently and safely charged.”
On the cable-connected charging side of things, Mercedes-Benz finally announced the implementation of CCS (Combined Charging System) from 2018, introducing it to all its future electric vehicles.
The CCS connection is capable of accepting 150 kW charging, with 350 kW to be perhaps introduced later in the future.
Why 2018? Well, becaase new all-electric long-range Mercedes are expected to appear at that time, starting with a new/upgraded B-Class 250 e we believe.
“AC + DC = Combined Charging System (CCS)
Public fast charging is increasingly gaining in importance. In the past years, Daimler, in conjunction with other automotive manufacturers, has decisively advanced the development of the Combined Charging System into an open and universal charging system for electric vehicles. The system pursues the goal of unlimited, global e-mobility. It expands the existing technical standard for AC charging of electric vehicles with the capacity for DC fast charging. From 2018 direct current charging based on the CCS standard will gradually find its way into all electric vehicles from Mercedes-Benz. Depending on the vehicle and battery system, this enables a charging capacity of up to 150 kW at fast charging stations. Perspectively, the system also enables a charging capacity of up to 350 kW.”
