BMW i7 Home Charging: Time, Cost and the Right Charger
The BMW i7's onboard AC charger takes 22 kW as standard. At home, charging from 20% to 80% with a 22 kW charger takes: xDrive60 (101.7 kWh) 3 h 5 min, M70 xDrive (112.4 kWh) 3 h 24 min. Charging at home costs about £4.84-5.55 per 100 km at UK household prices.

BMW i7 versions
| Version | Battery capacity | Onboard AC | DC peak power | Average consumption |
|---|---|---|---|---|
| xDrive60 | 101.7 kWh | 22 kW | 195 kW | 18.4-19.6 kWh / 100 kmWLTP |
| M70 xDrive | 112.4 kWh | 22 kW | 250 kW | 21.1 kWh / 100 kmWLTP |
Values come from the manufacturer's technical data for the Turkish market. WLTP consumption is measured at the grid and includes charging losses; the cost calculation counts this loss only once.
Versions and values refer to the models sold in Türkiye; equipment and charging power can differ in your country.
Home charging time (20% to 80%)
Charging speed is set by the car's onboard AC charger, not by the wallbox. The BMW i7 takes at most 22 kW with the standard unit; a more powerful charger cannot exceed this limit.

According to EV Database, the BMW i7 does not support V2L (vehicle-to-load). For camping or site work, C2L adapters that take power from a charging point work independently of the car.
V2L and C2L adaptersFrequently asked questions
- How long does the BMW i7 take to charge at home?
- From 20% to 80%: with a 22 kW charger xDrive60 (101.7 kWh) 3 h 5 min, M70 xDrive (112.4 kWh) 3 h 24 min; with a single-phase 7.4 kW charger xDrive60 (101.7 kWh) 9 h 10 min, M70 xDrive (112.4 kWh) 10 h 8 min; with a 3.7 kW (16 A single-phase) portable charger xDrive60 (101.7 kWh) 18 h 19 min, M70 xDrive (112.4 kWh) 20 h 15 min. Times depend on the car's onboard AC charger and the battery's state of charge.
- Which charger is right for the BMW i7?
- Because the car's onboard AC charger takes 22 kW as standard, a three-phase 22 kW wallbox at home gives the fastest charging the car can accept. On a single-phase supply, a 7.4 kW wallbox is usually enough for everyday use.
- How much does it cost to charge the BMW i7 at home?
- At the Ofgem price cap (£0.26/kWh, 10.2026) 100 km costs about £4.84-5.55. At public AC chargers you pay about £9.94-11.39 on average, at DC rapid chargers about £13.86-15.89. Tariffs with cheaper night rates lower the cost further.
- Does the BMW i7 support V2L?
- According to EV Database, the BMW i7 does not support V2L (vehicle-to-load). For camping or site work, C2L adapters that take power from a charging point work independently of the car.
