BYD SEALION 7 vs Hyundai IONIQ 5

Side-by-Side Specs

Charging Speed

The Hyundai IONIQ 5 has the higher published DC fast-charging figure at 263 kW, which is roughly 14% higher than the BYD SEALION 7 at 230 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 Hyundai IONIQ 5 finishes in about 18 minutes, which is 6 minutes quicker than the BYD SEALION 7 at 24 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The Hyundai IONIQ 5 has a WLTP rated range of approximately 570 km, which is roughly 50 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 Hyundai IONIQ 5 consumes 178 Wh/km, compared to 208 Wh/km for the BYD SEALION 7. That means the Hyundai IONIQ 5 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 Hyundai IONIQ 5 has approximately 80 kWh of useable battery , while the BYD SEALION 7 has approximately 91.3 kWh.

Which One Should You Choose?

If fast charging is your priority, the Hyundai IONIQ 5 has the higher published DC figure (up to 263 kW) while matching the quickest published 10-80% time at approximately 18 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 Hyundai IONIQ 5 is the more efficient choice at 178 Wh/km. Lower consumption means lower electricity bills over time.

For maximum range between charges, the Hyundai IONIQ 5 has a WLTP rated range of approximately 570 km, which is roughly 50 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
