Charging Speed

The BYD SEAL U has the higher published DC charging figure at 140 kW, which is roughly 25% higher than the Mercedes-Benz EQC at 112 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 SEAL U is listed at about 34 minutes, which is 2 minutes quicker than the Mercedes-Benz EQC at 36 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 89 km more than the Mercedes-Benz EQC at approximately 411 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 BYD SEAL U consumes 205 Wh/km, compared to 223 Wh/km for the Mercedes-Benz EQC. That means the BYD SEAL U 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 Mercedes-Benz EQC has approximately 80 kWh.

Which One Should You Choose?

If fast charging is your priority, the BYD SEAL U has the higher published DC figure (up to 140 kW) and the shorter published charge time at approximately 34 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 BYD SEAL U is the more efficient choice at 205 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 89 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
