Quick answer
The BYD SEAL charges from 10% to 80% in about 36 minutes on a DC fast charger (150 kW peak). A full charge at home on a 7 kW wallbox takes approximately 13 h 6 min.
Charging Times at Every Speed
These times are estimates based on the BYD SEAL's 82.5 kWh useable battery. Real charging times vary with temperature, battery condition, and state of charge.
| Charger | Power | 0 to 100% | 10 to 80% | Range/hour |
|---|---|---|---|---|
| Home 7 kW | 7 kW AC | 13 h 6 min | - | 37 km/h |
| Public AC 11 kW | 11 kW AC | 8 h 20 min | - | 58 km/h |
| Public AC 22 kW | 11 kW AC* | 8 h 20 min | - | 58 km/h |
| DC Fast | up to 150 kW | ~1 h 19 min | 36 min | - |
* The BYD SEAL's onboard charger is limited to 11 kW AC, so it cannot use the full power of a 22 kW charger.

What Affects Charging Time?
The charging curve matters more than peak power. The BYD SEAL can accept up to 150 kW from a DC fast charger, but it only reaches that speed at lower states of charge. As the battery fills past 60-70%, the charging speed tapers off to protect battery health. That is why charging from 10% to 80% is much faster per percentage point than charging from 80% to 100%.
Temperature has a big effect. In cold weather, the battery's internal resistance increases and the car limits charging power to prevent damage. The BYD SEAL does not support automatic battery preconditioning, so cold weather charging may be noticeably slower.
Battery chemistry plays a role. The BYD SEAL uses LFP cells, which handle charging to 100% better than NMC batteries but may charge slightly slower in cold conditions. Its 800V architecture enables higher charging speeds at compatible stations.
Tips for Faster Charging
- If possible, drive for a while before fast charging. A warm battery charges faster than a cold one.
- Charge between 20% and 80% for the fastest DC speeds. The last 20% can take as long as the first 60%.
- Avoid charging above 80% on road trips. The time spent waiting for 80-100% is rarely worth the extra range.
- Cold weather slows charging. In winter, expect 10-30% longer charging times depending on conditions.
- LFP batteries benefit from occasional charges to 100%. This also helps recalibrate the battery gauge.
