Quick verdict
The BYD SEAL has the higher published DC fast-charging figure at 150 kW, but the Polestar 2 actually finishes the 10-80% charge just as fast (34 min) in the current published data. The BYD SEAL is more efficient at approximately 172 Wh/km. The BYD SEAL offers more WLTP rated range at 570 km.
Side-by-Side Specs
| Spec | BYD SEAL | Polestar 2 |
|---|---|---|
| Compared variant | 82.5 kWh RWD Design | Long Range Single Motor (MY21-22) |
| Battery (approx.) | ~82.5 kWh | ~75 kWh |
| WLTP range (rated) | ~570 km | ~551 km |
| Efficiency (approx.) | ~172 Wh/km | ~179 Wh/km |
| DC fast charging (published) | up to 150 kW | up to 149 kW |
| 10-80% charge time (approx.) | ~36 min | ~34 min |
| Max AC charging | up to 11 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The BYD SEAL has the higher published DC fast-charging figure at 150 kW, which is roughly 1% higher than the Polestar 2 at 149 kW. In practice, that figure only tells part of the story. The charging curve, battery temperature, and state of charge all affect how quickly your car actually charges.
For the 10-80% charge (the most common DC fast charging scenario), the Polestar 2 finishes in about 34 minutes, which is 2 minutes quicker than the BYD SEAL at 36 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The BYD SEAL has a WLTP rated range of approximately 570 km, which is roughly 19 km more than the Polestar 2 at approximately 551 km. WLTP is a standardized lab test. Expect your actual range to be lower, varying with speed, weather, terrain, and driving style.
Efficiency matters more than battery size for daily driving costs. The BYD SEAL consumes 172 Wh/km, compared to 179 Wh/km for the Polestar 2. That means the BYD SEAL uses less energy per kilometer, which translates to lower charging costs and fewer charging stops on longer drives.
A more efficient car does not always mean more range. Battery size plays a role too. The BYD SEAL has approximately 82.5 kWh of useable battery , while the Polestar 2 has approximately 75 kWh.
Which One Should You Choose?
The BYD SEAL has the higher published DC figure at up to 150 kW, but the Polestar 2 actually finishes the 10-80% charge faster at approximately 34 minutes versus approximately 36 minutes. On road trips, published stop time matters more than the headline kW number alone.
Both cars support 11 kW AC charging, so home and workplace charging speeds will be similar.
If you mostly charge at home or at work and care more about daily driving costs, the BYD SEAL is the more efficient choice at 172 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the BYD SEAL has a WLTP rated range of approximately 570 km, which is roughly 19 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.

From Finn, engineer: Charging specs alone do not tell the full story. Real-world charging speed depends on battery temperature, state of charge, and the charger itself. These comparisons use manufacturer-published data. Approximate values only.
