Mercedes-Benz EQA
Charging curve · consumption · motorway range
The Mercedes-Benz EQA has 70.5 kWh of usable battery and peaks at 102 kW on a DC charger. In this app's model it uses about 179 Wh/km at a steady 100 km/h and 264 Wh/km at 130, so 47% more energy per kilometre buys you 30 km/h more speed. Weigh that against a 35-minute 10-80% charging stop and you have the whole question of how fast to drive.

DC charging curve
Charging power against state of charge, on a charger fast enough not to be the limit. Peak power is 102 kW, but it has halved by about 78% state of charge. That is why a short stop low down the curve usually beats a long one near the top.
How long a stop takes
| Charge from | Time | Energy added | Average power |
|---|---|---|---|
| 10% to 80% | 35 min | 49.4 kWh | 84 kW |
| 20% to 80% | 31 min | 42.3 kWh | 82 kW |
| 10% to 60% | 21 min | 35.3 kWh | 100 kW |
| 20% to 70% | 23 min | 35.3 kWh | 92 kW |
| 80% to 100% | 32 min | 14.1 kWh | 26 kW |

Consumption and range by cruise speed
Steady motorway cruising on flat road in mild weather, from the fitted model Wh/km = 56 + 0.0123 · v². The “usable range” column is the honest one for trip planning: it is 100% down to 10%, because nobody arrives on empty.
| Cruise speed | Consumption | Range (full pack) | Usable range (100 to 10%) |
|---|---|---|---|
| 90 km/h | 156 Wh/km | 453 km | 408 km |
| 100 km/h | 179 Wh/km | 394 km | 354 km |
| 110 km/h | 205 Wh/km | 344 km | 310 km |
| 120 km/h | 233 Wh/km | 302 km | 272 km |
| 130 km/h | 264 Wh/km | 267 km | 240 km |
| 140 km/h | 297 Wh/km | 237 km | 214 km |
| 150 km/h | 333 Wh/km | 212 km | 191 km |
| 160 km/h | 371 Wh/km | 190 km | 171 km |
What the model does not include
- Elevation. The trip planner does account for climbs and descents; the range figures on this page are flat-road, so an alpine route will come out worse than the table.
- Temperature. These are mild-weather numbers. Cold raises consumption and cuts the charging curve. The planner models both. The numbers on this page do not.
- Wind, rain, roof boxes, payload and tyre choice, all of which move real consumption more than most people expect.
- Charger-side limits. The charging times above assume the site can deliver whatever the car asks for. A 150 kW cabinet shared with the car next to you will not.
Where these numbers come from
Mercedes EQA 250+ (2023-2026): a 400 V car with the lowest peak of any European entry here at 102 kW, held past 50% SoC so the 35-minute 10-80% is better than that number suggests. Limited to 160 km/h. Curve fitted to EV Database's published 10-80% time.
What speed should you actually drive?
It depends on your route, on where the fast chargers happen to be and how the legal limits fall. Plan the real trip and the simulator will sweep every cruise speed against this car's curves and tell you which one arrives first.
