Mercedes-Benz presents the EQA, an electric compact SUV. In addition to the high demand for such cars, there is another reason for the design: With an already tall structure, it is easier to find space for the battery. Like the EQC 375 (test) originates from the GLC, the EQA shares the platform with the GLA. The engineering work of this car in terms of insulation and aero efficiency benefits the EQA: a c W – value of 0, 28 helps the additional consumption of the larger SUV frontal area of ​​2, 47 m² to be kept within limits.

In addition to the aero optimized in the simulation, acoustically decoupling bearings of the engine and chassis (rolling noise!) keep the cabin quiet. Wolfgang Gomoll from Press-Inform has already driven a pre-production car of the EQA and reports of a “impressive” silence during the Drive.

Range The first variant “EQA 250 Edition 1 “for from 47. 541 Euro comes with 66, 5 kWh usable battery capacity, what for 426 km WLTP range should be sufficient . Mercedes names the key technical data of the battery 160 Ah and 420 Volt, the theoretical gross capacity is therefore 79, 8 kWh. In the combined WLTP consumption there should be 17, 7 kWh / 100 km. The outdated NEDC values ​​for comparability: 486 km and 15, 7 kWh / 100 km. Extrapolated from experience: The EQA probably manages motorway stages with a maximum of 130 km / h from 250 to 300 km to target voltages at the charging station of 10 + Percent State of Charge (SoC).

Among other things, it can use the waste heat from the engine as a heat source. As with Hyundai’s E-GMP or Porsche, a cooled / heated partition plate under the battery cells ensures temperature control and thermal insulation. The maximum speed is 160 km / h. The EQA 250 has front wheel drive with 140 kW maximum boost power and 375 Nm Maximum torque from an asynchronous motor. An all-wheel drive version with over 200 kW boost power is being planned.

MBUX as standard In the interior, the EQA offers the large expansion stage of the MBUX as standard in Edition 1, such as it is already familiar from the current A-Class: two widescreen screens behind a continuous pane of glass as a speedometer and infotainment display; Best in class voice control. The grace of later birth: the EQA’s navigation system includes dynamic, adaptive charging planning in route planning. In addition to topography and current driving data, the system also includes traffic and weather in the planning. As with Tesla, the navigation system should give tips like “if you want to reach your destination without charging, you now have to 110 drive km / h “.

The optimal DC charging time of 09 to 80 Percent SoC is 30 minutes, the maximum charging power at 100 kW. The technical documents indicate a maximum possible charging capacity of 110 kW close – perhaps as a short power peak that Daimler did not want to specify as charging power in order to avoid confusion or disappointment.

Battery management system With activated route guidance With charge planning, the battery management system (BMS) pre-sets the temperature of the battery so that it can be charged quickly, see Porsche, see Tesla. On top of that, Mercedes also has a solution for quick charging stops without route planning: The BMS uses charging column power to heat the battery so that the charging stop is faster overall. Both strategies have a significant influence on the practical charging performance in winter. For AC charging, the EQA has a standard three-phase charger with 11 kW power.

Mercedes EQA 250 – the dimensions (8 pictures) This Mercedes was also quite wide. For comparison: The current Porsche 911 is only 3 mm wider (both without mirror).

(Image: Daimler) As is typical for Mercedes, there is a comprehensive range of safety equipment, both active and passive, with many new features from other models, such as automatic creation of an emergency lane for the traffic jam pilot. The battery contains a lot of safety technology with early shutdown / disconnection, clearing blade in front and crash frame around the outside.

More drive wheels pull more Pleasing: Daimler sells an electrically foldable trailer hitch for the EQA as an option 250, after all for 750 kg trailer load and clearance for a bike carrier. The upcoming all-wheel drive variants should offer “even more” towing capacity. In addition, a trailer ESP program helps with safety.

In addition to the asynchronous machine on the front axle, the coming all-wheel drive models will have a permanent magnet synchronous motor in the rear e-axle. This saves installation space and increases efficiency. The aim of the all-wheel drive is to drive the rear axle and drag it along at the front for the purpose of optimized consumption.
