BYD Sealion 7
Charging curve · consumption · motorway range
The BYD Sealion 7 has 82.5 kWh of usable battery and peaks at 150 kW on a DC charger. In this app's model it uses about 180 Wh/km at a steady 100 km/h and 260 Wh/km at 130, so 44% 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 150 kW, but it has halved by about 67% 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 | 57.8 kWh | 100 kW |
| 20% to 80% | 31 min | 49.5 kWh | 95 kW |
| 10% to 60% | 20 min | 41.3 kWh | 127 kW |
| 20% to 70% | 23 min | 41.3 kWh | 109 kW |
| 80% to 100% | 45 min | 16.5 kWh | 22 kW |

Consumption and range by cruise speed
Steady motorway cruising on flat road in mild weather, from the fitted model Wh/km = 64 + 0.0116 · 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 | 158 Wh/km | 522 km | 470 km |
| 100 km/h | 180 Wh/km | 458 km | 413 km |
| 110 km/h | 204 Wh/km | 404 km | 363 km |
| 120 km/h | 231 Wh/km | 357 km | 321 km |
| 130 km/h | 260 Wh/km | 317 km | 286 km |
| 140 km/h | 291 Wh/km | 283 km | 255 km |
| 150 km/h | 325 Wh/km | 254 km | 228 km |
| 160 km/h | 361 Wh/km | 229 km | 206 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
BYD Blade LFP pack: a modest peak held broadly flat rather than a tall spike, and a long slow tail, so these cars want to be unplugged early. Approximated from published fast-charge and motorway-consumption tests. Fewer independent runs exist for this model than for the European cars here, so treat the curve — especially above 70% SoC — as indicative. Seal running gear in a heavier coupé-SUV body — same charge ceiling, noticeably more energy per kilometre.
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.
