Design 87 kWh · 87.0 kWh usable · 140 kW DC peak
Charging a 2024 BYD Seal U from 10% to 80% takes about 28 min at its 140 kW DC peak, or 6 hr 9 min at 11.0 kW on a home charger. At €0.35/kWh, that 70% top-up costs €22.68 on DC and €23.68 at home.

2024 BYD Seal U Design 87 kWh · 87.0 kWh
11.0 kW average at the plug · 90% charging efficiency · €7.32 per 100 km
DC time is modelled on the vehicle’s verified 28-minute 10–80% figure, including its taper curve — not a flat peak-power division.
Reference
A standard 10–80% stop, priced at €0.35/kWh. The same engine powers the calculator above — change the sliders there for any window.
| Charger | Power | 10→80% | Cost |
|---|---|---|---|
| Level 1 wall outlet 1.4 kW | 1.4 kW | 51 hr 47 min 60.9 kWh added | €25.38 |
| Level 2 home charger 7.4 kW | 7.4 kW | 9 hr 9 min 60.9 kWh added | €23.68 |
| Level 2 home charger 11.0 kW | 11.0 kW | 6 hr 9 min 60.9 kWh added | €23.68 |
| DC fast charger 140.0 kW | 140.0 kW | 28 min 60.9 kWh added | €22.68 |
Level 1 figures assume a 1.4 kW household outlet at 84% efficiency. Level 2 and DC figures use 90% and 94% respectively. DC time follows the car’s verified 10–80% figure of 28 minutes, including taper.
Running costs
All three numbers use the same €0.35/kWh tariff and the 11.0 kW onboard charger — the realistic home ceiling, not the DC headline.
Full charge (0→100%)
€33.83
96.7 kWh drawn at the meter, about 8 hr 47 min on a home charger.
Electricity per 100 mi
€11.78
30.3 kWh / 100 mi at the battery. 287 mi of rated range from a full pack.
Monthly home cost
€117.85
1,000 miles a month at home: 337 kWh at the meter.
DC fast charging typically costs two to three times more per kWh than home charging, so the session price above is the floor, not the average. If your utility offers a time-of-use tariff, schedule the car overnight and use the off-peak rate in the calculator.
Tesla network access for this exact model
Not covered by Tesla’s adapter or Plug & Charge programme.
No adapter for this car: the Type 2 AC port and CCS2 DC port cover home charging and its supported public networks without extra hardware.

Physical match, not a paid placement: every AC unit must carry the car’s connector, and an adapter is only listed when the vehicle declares one is required. Units far above 11.0 kW are marked amber — they work, but the car caps them. We may earn a commission from these links.
The physics
The Seal U carries 87.0 kWh of usable capacity, so a 10–80% window moves 60.9 kWh into the pack. That usable figure — not the gross capacity on the spec sheet — is what every time and cost here is built from, because the buffer above and below the usable window is never charged.
On AC the ceiling is the onboard charger: 11.0 kW through a Type 2 port. A 48 A wallbox rated at 11.5 kW cannot push more than 11.0 kW into this car, which is why a bigger home charger is not an upgrade.
On DC the 140 kW peak only holds for part of the session. We calibrate a taper curve to the verified 28-minute 10–80% time, so a 20–90% session, a 10–60% splash-and-go and a full charge are all modelled with the right shape instead of a flat peak-power division.
At 3.3 mi/kWh, 100 miles needs about 30.3 kWh at the battery and 33.7 kWh at the meter — roughly €11.78 of home electricity. That running cost, not the charger price, is the number that compounds every month.
About 28 min on a DC fast charger at the car’s 140 kW peak — that is the 28-minute 10–80% figure the manufacturer publishes and the one this calculator models. At 11.0 kW on a Level 2 home charger, the same 10–80% window takes roughly 6 hr 9 min.
At €0.35/kWh, a 20–80% home session adds 52.2 kWh to the 87.0 kWh usable pack and costs about €20.30. Charging from empty to full costs roughly €33.83 at the same tariff — about 96.7 kWh drawn at the meter.
No. Tesla does not list the BYD BYD Seal U in its Supercharger adapter or Plug & Charge programme, so don’t plan around Superchargers. Use CCS2 public networks such as Ionity, Fastned and Allego instead; home and destination AC charging is unaffected.
The Seal U has a Type 2 AC port and accepts up to 11.0 kW. Any Type 2 Level 2 charger will work; a unit rated above 11.0 kW is safe but the car will never draw more than that. This page lists 6 verified Type 2 units, each checked against the port and the onboard charger limit.
At €0.35/kWh and 3.3 mi/kWh, 100 miles needs about 30.3 kWh at the battery and roughly 33.7 kWh at the meter, so about €11.78 — or €7.32 per 100 km. DC fast charging usually costs more per kWh than charging at home.
