BYD Sealion 7 Dynamic charging cost & time
| Scenario | Energy | Time | Cost |
|---|---|---|---|
| Public DC 20% → 80% | 43.1 kWh | 28 minutes | $33.17 |
| Public DC 0% → 100% | 71.8 kWh | 1 hours 11 minutes | $55.29 |
| At home (AC) 20% → 80% | 43.1 kWh | 3 hours 55 minutes | $12.80 |
BYD Sealion 7 Dynamic charging time by charger power
How long the BYD Sealion 7 Dynamic 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% | 32 hours 38 minutes |
| Home wallbox | 7 kW | 0% → 100% | 10 hours 15 minutes |
| Public AC | 11 kW | 0% → 100% | 6 hours 32 minutes |
| DC fast | 150 kW | 10% → 80% | 32 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%) is anchored to a measured charging time for this model, so it reflects the real charging curve. Times still vary with temperature and conditions.
Charging speed
Based on measured data, the BYD Sealion 7 Dynamic charges 10% → 80% on DC fast charging in about 32 minutes, peaking at around 150 kW. Averages ~115 kW over the 10→80% session.
The BYD Sealion 7 Dynamic is estimated to charge from 20% to 80% on public DC fast charging in about 28 minutes (ultra-fast DC).

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 207 km of range for $33.17. Driving the same distance on petrol would cost:
| Engine size | Petrol cost | You save |
|---|---|---|
| ≤ 1000 cc | $39.31 | $6.13 |
| 1000–1500 cc | $46.45 | $13.28 |
| 1500–2000 cc | $57.17 | $24.00 |
| 2000–2500 cc | $67.89 | $34.72 |
| > 2500 cc | $82.19 | $49.01 |
Estimated from typical combined fuel use by engine size and RON95 at $3.46/L. Charging at home saves the most; actual figures vary with driving and conditions.
