BMW i7 Charging Time by Charger Type
Based on the electricy comsumption ratio unvailed, we’ve done the following calculation for the BMW i7 charging by different types of charging methods.
BMW i7 Charging Time might vary from different temperature, battery condition, charging equipment’s power output etc, therefore our calculaltion is under ideal condition with consideration of real world charging conditions.
Level 1 Charging (120V)
Using a standard home outlet, Level 1 charging is the slowest option but can be useful in emergencies.
- Charging Speed: 3.6 – 3.9 miles of range per hour
- Full Charge Time: Over 70 hours (not recommended for daily use)
Level 2 Charging (240V)
Level 2 charging is the preferred method for home charging, offering much faster charge times.
- 16A (3.8 kW): 9.4 miles per hour, full charge in 29.6 hours
- 32A (7.7 kW): 16.2 – 18.8 miles per hour, full charge in 14.8 hours
- 40A (9.6 kW): 20.3 – 23.5 miles per hour, full charge in 10.6 hours
- 48A (11.5 kW): Up to 28.2 miles per hour, full charge in 9.9 hours
DC Fast Charging (195 kW)
DC fast charging is the best option for quickly replenishing the BMW i7’s battery during long trips.
- Charging Speed: 7.4 – 8.1 miles per minute
- Time for 10%-80% Charge: Approximately 38 minutes
Home Charging Cost for BMW i7
Charging at home is the most economical option for BMW i7 owners. Based on an average electricity rate of $0.162 per kWh:
- Cost per 100 Miles: $6.16 – $6.80, depending on efficiency
- Full Charge Cost: Approximately $17.11
Public Charging Costs
Public DC fast charging is more expensive but provides significant time savings.
- Cost per kWh: $0.350 (average public fast charging)
- Cost per 100 Miles: $13.3 – $14.7, depending on location and provider
- Full Charge Cost: Approximately $36.96
Can the BMW i7 Charge at Tesla Superchargers?
BMW i7 models are not directly compatible with Tesla Superchargers but can access Tesla’s Magic Dock stations, which provide a built-in CCS adapter.
- Magic Dock Superchargers: Allow BMW i7 to charge at certain Tesla locations.
- Future Compatibility: BMW may integrate NACS ports in upcoming models for seamless Tesla charging.
Choosing the Best Home Charger for BMW i7 Charging
Selecting the right home charger can optimize BMW i7 charging time and efficiency:
- Recommended Charger: 48A Level 2 charger (supports 11 kW charging for the fastest home charging experience)
- Installation: A hardwired setup is preferred for reliability over plug-in chargers.
- Avoid lower amperage chargers (16A or 32A), as they significantly increase charging time.
Conclusion
Understanding how to charge BMW i7 is essential for maximizing convenience, efficiency, and cost savings. Whether charging at home with a Level 2 charger or using DC fast charging for quick power-ups, the BMW i7 charging process is designed for seamless performance. Future compatibility with Tesla Superchargers via Magic Dock stations and a growing CCS charging network ensures that BMW i7 owners have multiple charging options to fit their driving needs.
