Mercedes-Benz EQC: The Mercedes-Benz among electric vehicles
In mid-2019 the time has now come: The EQC (combined power consumption: 22.2 kWh/100 km; combined CO2 emissions: 0 g/km, provisional figures)1 is the first Mercedes-Benz vehicle to be launched under the EQ brand. With its seamless, clear design and colour highlights typical of the brand, it is a pioneer for an avant-garde electric look while representing the design idiom of Progressive Luxury. With respect to quality, safety and comfort the EQC is the Mercedes-Benz among electric vehicles, and highly convincing in the sum of its attributes. These are accompanied by dynamic performance, thanks to two electric motors at the front and rear axles with a combined output of 300 kW. A sophisticated operating strategy enables an electric range of more than 450 km according to NEDC (provisional figure)1. EQ also offers comprehensive services with Mercedes me, and makes electromobility convenient and suitable for day-to-day motoring. The intelligent services and functions available for the EQC extend from Route Planning and auxiliary climate control to new assistance functions and convenient charge handling.
By virtue of its muscular proportions, the EQC is classed as a crossover SUV. The extended roofline and window layout with a low waistline and the coupé-like roof recess at the rear visually position it between an SUV and an SUV coupé.
To reduce power consumption and increase dynamism, the electric drivetrains are configured differently: the front electric motor is optimised for best possible efficiency in the low to medium load range, while the rear one determines dynamism. Together, they generate an output of 300 kW and a maximum torque of 765 Nm.
The lithium-ion battery, which has an energy content of 80 kWh (NEDC) supplies the vehicle with power. The power consumption and range of electric vehicles depend very much on the driving style. The EQC supports its driver with five driving programs, each with different characteristics: COMFORT, ECO, MAX RANGE, SPORT and an individually adaptable program. In the more economical driving modes, the haptic accelerator pedal that prompts the driver to conserve power plays an important role. The driver is also able to influence the recuperation level using so-called paddles behind the steering wheel.
The ECO Assist system gives the driver comprehensive support when driving predictively: by prompting the driver when it is appropriate to come off the accelerator, e.g. because the vehicle is approaching a speed limit, and by functions such as coasting and specific control of recuperation. For this purpose, navigation data, traffic sign recognition and information from the intelligent safety assistants (radar and stereo camera) are linked and processed.
Relaxed traveling with high-voltage technology
Individual, specific services relating to electromobility have been around for a while. The EQC takes a new, comprehensive approach: intelligent networking of individual services and functions make it easier for EQC drivers to use their vehicle in every phase.
Pre-entry climate control, which ensures that the vehicle interior is already at the desired temperature on departure. The EQC is correspondingly cooled down or heated. Programming is possible in several ways: directly via MBUX - Mercedes-Benz User Experience or via the Mercedes me App, where either an individual departure time or a weekly profile can be input. On request, drivers receive push notifications on their mobile phone when the process starts and ends, and are therefore always up-to-date. Pre-entry climate control during a charging process extends vehicle range, as the energy requirement is covered by the charging current.
Via the EQ optimised navigation, Mercedes-Benz customers can quickly find public charging stations, have convenient access to the charging stations of different providers via Mercedes me Charge and benefit from an integrated payment function with easy accounting also at the stations of IONITY, the European quick-charging network. The objective is relaxed, uncomplicated travel with transparency and planning certainty.
EQ optimised navigation operates intelligently. It uses numerous factors to plan a route automatically, including any necessary charging stops. It takes into account e.g. the current electric range, the current power consumption, which is individually determined by the driving style, the topography and the traffic flow, and available charging stations. The route calculation is always based on the fastest route taking the shortest charging time into account – therefore quick-charging stations are given preference. Customers do not necessarily have to charge the vehicle fully, but can charge it to suit the total journey time. The route planning also responds dynamically to changes. It can take place both offboard and onboard, i.e. externally (via the Mercedes me App) and within the vehicle. The journey can therefore be conveniently planned at home before departure, or while already en route if required.
EQ specific voice control is activated with “ Hey Mercedes” and its natural language recognition makes operating the EQC easier. This is because the LINGUATRONIC of MBUX recognises and understands many questions and commands relating to electric car specific control aspects. A few examples: “ Show me the energy flow”, “What charging settings have been made?”, “Charge the vehicle to 85 percent” or “I want to leave at 8 a.m. tomorrow” or “Where is the nearest charging station?” For details see the section on MBUX – Mercedes-Benz User Experience.
Charging: Flexible and fast
As standard the EQC is equipped with a water-cooled onboard charger (OBC) with a capacity of 7.4 kW, making it suitable for AC charging at home or at public charging stations.
Charging at a Mercedes-Benz Wallbox is up to three times faster than at a domestic power socket. It is faster still with DC charging – which is standard for the EQC – for example via CCS (Combined Charging Systems) in Europe and the USA, CHAdeMO in Japan or GB/T in China. Depending on the SoC (status of charge), the EQC can be charged with a maximum output of up to 110 kW at an appropriate charging station. In around 40 minutes, the battery can be charged from 10 - 80 percent SoC (provisional data).
 Figures for power consumption and CO2 emissions are provisional and were determined by the German Technical Service corporation. The range figures are also provisional. EC type approval and conformity certification with official figures are not yet available. There may be differences between the stated figures and the official figures.
