BYD SEALION 7 vs Volvo EX30

Side-by-Side Specs

Charging Speed

The BYD SEALION 7 has the higher published DC charging figure at 230 kW, which is roughly 46% higher than the Volvo EX30 at 158 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 BYD SEALION 7 is listed at about 24 minutes, which is 4 minutes quicker than the Volvo EX30 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 502 km, which is roughly 26 km more than the Volvo EX30 at approximately 476 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 EX30 consumes 178 Wh/km, compared to 208 Wh/km for the BYD SEALION 7. That means the Volvo EX30 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 EX30 has approximately 65 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) and the shorter published charge time at approximately 24 minutes. For long 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 Volvo EX30 supports up to 11 kW (22 kW optional), compared to up to 11 kW for the BYD SEALION 7. 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 Volvo EX30 is the more efficient choice at 178 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 502 km, which is roughly 26 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
