Mercedes-Benz EQB
Charging curve · consumption · motorway range
The Mercedes-Benz EQB has 70.5 kWh of usable battery and peaks at 102 kW on a DC charger. In this app's model it uses about 196 Wh/km at a steady 100 km/h and 290 Wh/km at 130, so 48% 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 = 60 + 0.0136 · 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 | 170 Wh/km | 414 km | 373 km |
| 100 km/h | 196 Wh/km | 360 km | 324 km |
| 110 km/h | 225 Wh/km | 314 km | 283 km |
| 120 km/h | 256 Wh/km | 276 km | 248 km |
| 130 km/h | 290 Wh/km | 243 km | 219 km |
| 140 km/h | 327 Wh/km | 216 km | 194 km |
| 150 km/h | 366 Wh/km | 193 km | 173 km |
| 160 km/h | 408 Wh/km | 173 km | 155 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 EQB 250+ (2023-2026): the EQA's pack and charging hardware in a taller seven-seat body, so the curve here is deliberately identical and the consumption is not. Published motorway figures give the two bodies the same number, which cannot be right for a box this much larger; the quadratic term has been raised for its frontal area, and that adjustment is ours rather than a measurement.
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.
