Side-by-Side Specs
| Spec | BYD SEAL U | Volvo EX40 |
|---|---|---|
| Compared variant | 87 kWh Design | Single Motor Extended Range |
| Battery (approx.) | ~87 kWh | ~79 kWh |
| WLTP range (rated) | ~500 km | ~576 km |
| Efficiency (approx.) | ~205 Wh/km | ~198 Wh/km |
| DC fast charging (published) | up to 140 kW | up to 207 kW |
| 10-80% charge time (approx.) | ~34 min | ~32 min |
| Max AC charging | up to 11 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The Volvo EX40 has the higher published DC charging figure at 207 kW, which is roughly 48% higher than the BYD SEAL U at 140 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 published fast-charge window, the Volvo EX40 is listed at about 32 minutes, which is 2 minutes quicker than the BYD SEAL U at 34 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The Volvo EX40 has a WLTP rated range of approximately 576 km, which is roughly 76 km more than the BYD SEAL U 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 EX40 consumes 198 Wh/km, compared to 205 Wh/km for the BYD SEAL U. That means the Volvo EX40 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 Volvo EX40 has approximately 79 kWh of useable battery , while the BYD SEAL U has approximately 87 kWh.
Which One Should You Choose?
If fast charging is your priority, the Volvo EX40 has the higher published DC figure (up to 207 kW) and the shorter published charge time at approximately 32 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 EX40 is the more efficient choice at 198 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the Volvo EX40 has a WLTP rated range of approximately 576 km, which is roughly 76 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.
