Side-by-Side Specs
| Spec | BYD SEAL | XPENG P7 |
|---|---|---|
| Compared variant | 82.5 kWh RWD Design | RWD Long Range |
| Battery (approx.) | ~82.5 kWh | ~82.7 kWh |
| WLTP range (rated) | ~570 km | ~580 km |
| Efficiency (approx.) | ~166 Wh/km | ~167 Wh/km |
| DC fast charging (published) | up to 150 kW | up to 175 kW |
| 10-80% charge time (approx.) | ~36 min | ~28 min |
| Max AC charging | up to 11 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The XPENG P7 has the higher published DC charging figure at 175 kW, which is roughly 17% higher than the BYD SEAL at 150 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 XPENG P7 is listed at about 28 minutes, which is 8 minutes quicker than the BYD SEAL at 36 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The XPENG P7 has a WLTP rated range of approximately 580 km, which is roughly 10 km more than the BYD SEAL at approximately 570 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 consumes 166 Wh/km, compared to 167 Wh/km for the XPENG P7. That means the BYD SEAL 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 XPENG P7 has approximately 82.7 kWh of useable battery , while the BYD SEAL has approximately 82.5 kWh.
Which One Should You Choose?
If fast charging is your priority, the XPENG P7 has the higher published DC figure (up to 175 kW) and the shorter published charge time at approximately 28 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 is the more efficient choice at 166 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the XPENG P7 has a WLTP rated range of approximately 580 km, which is roughly 10 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.
