A real-world estimate discounted from the manufacturer's claimed figure; actual distance depends on driving style, speed, and conditions.
Estimated from the realistic range, not a measured consumption figure; actual use varies with driving and conditions.
BYD Seagull charging cost & time
| Scenario | Energy | Time | Cost |
|---|---|---|---|
| Public DC 20% → 80% | 22.2 kWh | 40 minutes | ¥39.96 |
| Public DC 0% → 100% | 37 kWh | 1 hours 41 minutes | ¥66.60 |
| At home (AC) 20% → 80% | 22.2 kWh | 3 hours 22 minutes | ¥13.32 |
BYD Seagull charging time by charger power
How long the BYD Seagull takes to charge at different charger power levels, capped by its own onboard limits.
| Charger | Power | Charge | Time |
|---|---|---|---|
| Standard outlet | 2.2 kW | 0% → 100% | 16 hours 49 minutes |
| Home wallbox | 6.6 kW | 0% → 100% | 5 hours 36 minutes |
| Public AC | 6.6 kW | 0% → 100% | 5 hours 36 minutes |
| DC fast | 40 kW | 10% → 80% | 45 minutes |
AC rows assume constant charging power and a 0% to 100% charge. Real times vary with the onboard charger, temperature, and the charger you use.
The DC fast row (10% to 80%) models the charging curve tapering as the battery fills, so it is more realistic than a flat estimate. Real DC times still vary with temperature, battery state, and the charger.
Charging speed
The BYD Seagull is estimated to charge from 20% to 80% on public DC fast charging in about 40 minutes (standard DC).
Estimated. Real DC charging slows as the battery fills, so the time varies by model, temperature, and charger.

Battery care
This car uses an LFP battery, which tolerates routine charging to 100%. Charging full now and then is fine and even helps the car read its charge level accurately.
Savings vs a petrol car
This charge adds about 194 km of range for ¥39.96. Driving the same distance on petrol would cost:
| Engine size | Petrol cost | You save |
|---|---|---|
| ≤ 1000 cc | ¥94.62 | ¥54.66 |
| 1000–1500 cc | ¥111.83 | ¥71.87 |
| 1500–2000 cc | ¥137.64 | ¥97.68 |
| 2000–2500 cc | ¥163.44 | ¥123.48 |
| > 2500 cc | ¥197.85 | ¥157.89 |
Estimated from typical combined fuel use by engine size and Gasoline 92# at ¥8.85/L. Charging at home saves the most; actual figures vary with driving and conditions.
