How much does charging cost?
Compare batteries using your tariffs. Initial values of 0.30 and 0.65 €/kWh are examples, not offers or market averages.
Supply energy = usable capacity × charge change ÷ (1 − losses). Costs cover energy only, excluding subscriptions and other charges. Actual losses vary with power, installation and temperature.
Example from 20–80%, with assumed losses of 10%.
| Version | Estimated supply energy | Home | Public |
|---|---|---|---|
| i7 M70 xDrive | 67.8 kWh | 20.34 € | 44.07 € |
| i7 xDrive60 | 67.8 kWh | 20.34 € | 44.07 € |

AC charging time from 20–80%
Energy stored in this window is approximately 61 kWh. With 10% losses, estimated supply energy is 67.8 kWh.
| Available power | Applied limit | Estimated time |
|---|---|---|
| 2.3 kW | 2.3 kW | 29 h 29 min |
| 3.7 kW | 3.7 kW | 18 h 20 min |
| 7.4 kW | 7.4 kW | 9 h 10 min |
| 11 kW | 11 kW | 6 h 10 min |
| 22 kW | 22 kW | 3 h 05 min |
Simplified estimate: stored energy ÷ 0.90 ÷ effective power. Power is the lower of available power and the version's AC limit. Constant power is assumed: installation, phases, temperature and battery management can extend time. Listed powers are calculation scenarios, not an installation assessment.
Rapid DC charging
No DC time reference with a battery window is reported for this version. Peak kW cannot establish actual time: power varies with battery, temperature and station. The full calculator uses an estimated curve and explains its limits.

How to use these results
A 22 kW AC station cannot exceed the onboard charger limit. For BMW i7, the individual version figures in the table are more useful than the commercial name alone. Also check available power and installation phases.
Estimated cost multiplies supply kWh by your tariff. DC charging follows a curve and cannot be calculated by dividing energy by peak power. Sources and reference windows are listed for each version.
