Kia EV3
Charging curve · consumption · motorway range
The Kia EV3 has 78 kWh of usable battery and peaks at 135 kW on a DC charger. In this app's model it uses about 183 Wh/km at a steady 100 km/h and 269 Wh/km at 130, so 47% more energy per kilometre buys you 30 km/h more speed. Weigh that against a 32-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 135 kW, but it has halved by about 75% 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% | 32 min | 54.6 kWh | 101 kW |
| 20% to 80% | 28 min | 46.8 kWh | 99 kW |
| 10% to 60% | 20 min | 39.0 kWh | 117 kW |
| 20% to 70% | 20 min | 39.0 kWh | 115 kW |
| 80% to 100% | 52 min | 15.6 kWh | 18 kW |

Consumption and range by cruise speed
Steady motorway cruising on flat road in mild weather, from the fitted model Wh/km = 58 + 0.0125 · 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 | 159 Wh/km | 490 km | 441 km |
| 100 km/h | 183 Wh/km | 426 km | 384 km |
| 110 km/h | 209 Wh/km | 373 km | 335 km |
| 120 km/h | 238 Wh/km | 328 km | 295 km |
| 130 km/h | 269 Wh/km | 290 km | 261 km |
| 140 km/h | 303 Wh/km | 257 km | 232 km |
| 150 km/h | 339 Wh/km | 230 km | 207 km |
| 160 km/h | 378 Wh/km | 206 km | 186 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
Kia EV3 (MY25-26): E-GMP underneath but a 400 V pack, so it charges nothing like the 800 V EV6 above it: 135 kW and 33 minutes for 10-80%, against the EV6's 240 kW. Buyers routinely expect otherwise. Curve fitted to the 10-80% time published by EV Database. Charge curve measured, not drawn: digitized from published Fastned and InsideEVs plots by Morin et al., figshare doi:10.1184/R1/30570653 (CC BY 4.0), then reduced to anchor points that reproduce its charge times to within 2%.
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.
