Side-by-Side Specs
| Spec | BYD Dolphin | Kia EV2 |
|---|---|---|
| Battery (approx.) | ~60.5 kWh | ~58 kWh |
| WLTP range (rated) | ~427 km | ~400 km |
| Efficiency (approx.) | ~173 Wh/km | ~171 Wh/km |
| Max DC charging | up to 88 kW | up to 120 kW |
| 10-80% charge time (approx.) | ~41 min | ~27 min |
| Max AC charging | up to 11 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The Kia EV2 has a peak DC charging speed of 120 kW, which is roughly 36% faster than the BYD Dolphin at 88 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 Kia EV2 finishes in about 27 minutes, which is 14 minutes quicker than the BYD Dolphin at 41 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The BYD Dolphin has a WLTP rated range of approximately 427 km, which is roughly 27 km more than the Kia EV2 at approximately 400 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 Kia EV2 consumes 171 Wh/km, compared to 173 Wh/km for the BYD Dolphin. That means the Kia EV2 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 Dolphin has approximately 60.5 kWh of useable battery , while the Kia EV2 has approximately 58 kWh.
Which One Should You Choose?
If fast charging speed is your priority, the Kia EV2 wins on both peak power (up to 120 kW) and time at the plug (approximately 27 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 Kia EV2 is the more efficient choice at 171 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the BYD Dolphin has a WLTP rated range of approximately 427 km, which is roughly 27 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.
