Mercedes-Benz’s First Electric Car Is an SUV

Patrick Schäfer

Mercedes-Benz has unveiled the EQC. The first model of the new EQ electric brand is an SUV. The electric car will premiere at the Paris Motor Show and is slated for launch in mid-2019. 

Mercedes has presented its first electric car in Stockholm. A striking feature at the front of the Mercedes EQC SUV is the large black-panel surface enclosing the headlamps and grille. With a length of 4,761 millimetres, a width of 1,884 millimetres and a height of 1,624 millimetres, the electric SUV is about the size of a GLC Coupé. At the rear, the EQC carries a fashionable light band. The EQ series’ electric vehicles will, however, be designed more progressively in the future, said Jürgen Schenk, Chief Engineer Electric vehicles at Daimler, in an interview conducted in the May 2018 issue of ATZelektronik. 

The EQC’s kerb weight of almost 2.5 tonnes includes 650 kilograms for the lithium-ion batteries. The 384 cells from Daimler’s own production have a capacity of 80 kilowatt hours. Designed with heating and liquid cooling, the cells are split into two modules each with 48 cells, and 4 modules each with 72 cells. An intelligent control system distributes the power between the two axles, which are each driven by an asynchronous motor. 

The Mercedes EQC has one electric motor per axle

The motors operate at different ranges: the front electric motor is geared to the low to medium load range, while the rear one is designed for dynamism. Together, they drive all four wheels with a total output of 300 kilowatts (408 hp) and maximum torque of 765 newton metres. The EQC has five driving programs, from Eco to Sport, and its speed is limited to 180 km/h. The range should be over 450 kilometres according to the NEDC. The EQC is equipped with a water-cooled onboard charger (OBC) with an output of 7.4 kilowatts when plugged in at home, or a maximum output of up to 110 kilowatts with the rapid Combined Charging System, which reduces the charging time to around 40 minutes.

The cockpit has a large instrument panel comprising two 10.25-inch displays for the instrument cluster and multimedia. The infotainment system is familiar from the new A-Class; the MBUX can be operated either via voice control, on the touchscreen or via touchpad. With Mercedes me, the developers have networked various services and functions so that, for example, a navigation system is optimised to include rapid charging stations on the route.
