BYD Seal
Charging curve · consumption · motorway range
The BYD Seal has 82.5 kWh of usable battery and peaks at 150 kW on a DC charger. In this app's model it uses about 157 Wh/km at a steady 100 km/h and 225 Wh/km at 130, so 44% more energy per kilometre buys you 30 km/h more speed. Weigh that against a 34-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 68% 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% | 34 min | 57.8 kWh | 102 kW |
| 20% to 80% | 31 min | 49.5 kWh | 97 kW |
| 10% to 60% | 19 min | 41.3 kWh | 128 kW |
| 20% to 70% | 22 min | 41.3 kWh | 111 kW |
| 80% to 100% | 44 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 = 58 + 0.0099 · 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 | 138 Wh/km | 597 km | 537 km |
| 100 km/h | 157 Wh/km | 525 km | 473 km |
| 110 km/h | 178 Wh/km | 464 km | 418 km |
| 120 km/h | 201 Wh/km | 411 km | 370 km |
| 130 km/h | 225 Wh/km | 366 km | 330 km |
| 140 km/h | 252 Wh/km | 327 km | 295 km |
| 150 km/h | 281 Wh/km | 294 km | 264 km |
| 160 km/h | 311 Wh/km | 265 km | 238 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. The saloon is the aerodynamic one of the range (Cd ~0.22) and the only BYD here with a three-figure charge plateau.
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.
