Volvo EC40
Charging curve · consumption · motorway range
The Volvo EC40 has 79 kWh of usable battery and peaks at 200 kW on a DC charger. In this app's model it uses about 204 Wh/km at a steady 100 km/h and 301 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 = 63 + 0.0141 · 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 | 177 Wh/km | 446 km | 401 km |
| 100 km/h | 204 Wh/km | 387 km | 349 km |
| 110 km/h | 234 Wh/km | 338 km | 304 km |
| 120 km/h | 266 Wh/km | 297 km | 267 km |
| 130 km/h | 301 Wh/km | 262 km | 236 km |
| 140 km/h | 339 Wh/km | 233 km | 210 km |
| 150 km/h | 380 Wh/km | 208 km | 187 km |
| 160 km/h | 424 Wh/km | 186 km | 168 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 C40 Recharge — same pack and curve as the EX40, with a fastback roof worth a few percent of drag.
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.
