Volvo EX40
Charging curve · consumption · motorway range
The Volvo EX40 has 79 kWh of usable battery and peaks at 200 kW on a DC charger. In this app's model it uses about 214 Wh/km at a steady 100 km/h and 318 Wh/km at 130, so 48% more energy per kilometre buys you 30 km/h more speed. Weigh that against a 31-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 200 kW, but it has halved by about 56% 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% | 31 min | 55.3 kWh | 107 kW |
| 20% to 80% | 29 min | 47.4 kWh | 100 kW |
| 10% to 60% | 17 min | 39.5 kWh | 139 kW |
| 20% to 70% | 21 min | 39.5 kWh | 115 kW |
| 80% to 100% | 36 min | 15.8 kWh | 26 kW |

Consumption and range by cruise speed
Steady motorway cruising on flat road in mild weather, from the fitted model Wh/km = 64 + 0.015 · 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 | 186 Wh/km | 426 km | 383 km |
| 100 km/h | 214 Wh/km | 369 km | 332 km |
| 110 km/h | 246 Wh/km | 322 km | 290 km |
| 120 km/h | 280 Wh/km | 282 km | 254 km |
| 130 km/h | 318 Wh/km | 249 km | 224 km |
| 140 km/h | 358 Wh/km | 221 km | 199 km |
| 150 km/h | 402 Wh/km | 197 km | 177 km |
| 160 km/h | 448 Wh/km | 176 km | 159 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
Volvo CMA 82 kWh pack (2024 rear-motor Extended Range): ~200 kW peak that tapers from ~30% SoC. All Volvos are limited to 180 km/h. Curated from Fastned model guide + P3 Charging Index style tests. Formerly the XC40 Recharge; a boxy Cd 0.34 SUV, so motorway speed costs it more than almost anything else here.
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.
