Quick verdict
The BYD SEAL U has the higher published DC charging figure at 140 kW, but the published charge-time data matters more for road-trip stops. The BMW iX1 is listed at about 30 minutes versus 34 minutes for the BYD SEAL U. The BMW iX1 is more efficient at approximately 170 Wh/km. The BYD SEAL U offers more WLTP rated range at 500 km.
Side-by-Side Specs
| Spec | BMW iX1 | BYD SEAL U |
|---|---|---|
| Compared variant | xDrive30 | 87 kWh Design |
| Battery (approx.) | ~65.2 kWh | ~87 kWh |
| WLTP range (rated) | ~468 km | ~500 km |
| Efficiency (approx.) | ~170 Wh/km | ~205 Wh/km |
| DC fast charging (published) | up to 130 kW | up to 140 kW |
| 10-80% charge time (approx.) | ~30 min | ~34 min |
| Max AC charging | up to 11 kW (22 kW optional) | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The BYD SEAL U has the higher published DC charging figure at 140 kW, which is roughly 8% higher than the BMW iX1 at 130 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 BMW iX1 is listed at about 30 minutes, which is 4 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 BYD SEAL U has a WLTP rated range of approximately 500 km, which is roughly 32 km more than the BMW iX1 at approximately 468 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 BMW iX1 consumes 170 Wh/km, compared to 205 Wh/km for the BYD SEAL U. That means the BMW iX1 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 U has approximately 87 kWh of useable battery , while the BMW iX1 has approximately 65.2 kWh.
Which One Should You Choose?
The BYD SEAL U has the higher published DC figure at up to 140 kW, but the BMW iX1 has the shorter published charge time at approximately 30 minutes versus approximately 34 minutes. On road trips, published stop time matters more than the headline kW number alone.
For AC charging (home wallboxes, workplace chargers, and public street chargers), the BMW iX1 supports up to 11 kW (22 kW optional), compared to up to 11 kW for the BYD SEAL U. In Europe, many public chargers are 22 kW AC, so this difference can matter at those locations if the higher AC figure is fitted on the car you buy.
If you mostly charge at home or at work and care more about daily driving costs, the BMW iX1 is the more efficient choice at 170 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the BYD SEAL U has a WLTP rated range of approximately 500 km, which is roughly 32 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.
