Charging Speed
The BYD SEALION 7 has the higher published DC fast-charging figure at 230 kW, which is roughly 77% higher than the BMW iX2 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 10-80% charge (the most common DC fast charging scenario), the BYD SEALION 7 finishes in about 24 minutes, which is 5 minutes quicker than the BMW iX2 at 29 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 50 km more than the BMW iX2 at approximately 470 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 iX2 consumes 161 Wh/km, compared to 208 Wh/km for the BYD SEALION 7. That means the BMW iX2 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 BMW iX2 has approximately 65.2 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 BMW iX2 is the more efficient choice at 161 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 50 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.
