Charging Speed
The BYD SEALION 7 has a peak DC charging speed of 230 kW, which is roughly 31% faster than the Volkswagen ID.4 at 175 kW. In practice, peak speed 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 Volkswagen ID.4 at 28 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The Volkswagen ID.4 has a WLTP rated range of approximately 572 km, which is roughly 52 km more than the BYD SEALION 7 at approximately 520 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 Volkswagen ID.4 consumes 173 Wh/km, compared to 208 Wh/km for the BYD SEALION 7. That means the Volkswagen ID.4 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 Volkswagen ID.4 has approximately 77 kWh of useable battery , while the BYD SEALION 7 has approximately 91.3 kWh.
Which One Should You Choose?
If fast charging speed is your priority, the BYD SEALION 7 wins on both peak power (up to 230 kW) and time at the plug (approximately 24 minutes from 10-80%). For long road trips with multiple charging stops, that faster turnaround makes a real difference.
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 Volkswagen ID.4 is the more efficient choice at 173 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the Volkswagen ID.4 has a WLTP rated range of approximately 572 km, which is roughly 52 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.
