|---|---|---|
| Compared variant | 91.3 kWh AWD Excellence | Single Motor ER |
| Battery (approx.) | ~91.3 kWh | ~79 kWh |
| WLTP range (rated) | ~520 km | ~500 km |
| Efficiency (approx.) | ~208 Wh/km | ~188 Wh/km |
| DC fast charging (published) | up to 230 kW | up to 200 kW |
| 10-80% charge time (approx.) | ~24 min | ~28 min |
| Max AC charging | up to 11 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The BYD SEALION 7 has the higher published DC fast-charging figure at 230 kW, which is roughly 15% higher than the Volvo EC40 at 200 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 BYD SEALION 7 finishes in about 24 minutes, which is 4 minutes quicker than the Volvo EC40 at 28 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The BYD SEALION 7 has a WLTP rated range of approximately 520 km, which is roughly 20 km more than the Volvo EC40 at approximately 500 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 Volvo EC40 consumes 188 Wh/km, compared to 208 Wh/km for the BYD SEALION 7. That means the Volvo EC40 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 SEALION 7 has approximately 91.3 kWh of useable battery , while the Volvo EC40 has approximately 79 kWh.
Which One Should You Choose?
If fast charging is your priority, the BYD SEALION 7 has the higher published DC figure (up to 230 kW) while matching the quickest published 10-80% time at approximately 24 minutes. For long 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 Volvo EC40 is the more efficient choice at 188 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the BYD SEALION 7 has a WLTP rated range of approximately 520 km, which is roughly 20 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.
