Tips to Reduce Charging Costs
- Home charging is essential for the i7. At 101.7 kWh, a full charge at public fast charging rates costs significantly more than the same charge at home. A 22 kW wallbox is worth considering to fill the battery faster overnight.
- Use the BMW app to schedule charging during off-peak hours. With a battery over 100 kWh, even a small per-kWh difference between peak and off-peak rates results in substantial monthly savings.
- The i7 supports DC fast charging at up to 195 kW. On road trips, charge from 10% to 80% for the best balance of speed and cost. Above 80%, charging slows significantly.
- The i7's 520 km range means you may only need to charge at home two or three times a week. Avoid topping up at public chargers out of range anxiety when you have hundreds of kilometers available.
- Use Efficient mode for daily driving. The i7's luxury features and powerful motors consume more energy in Sport mode. Efficient mode can reduce consumption noticeably below 196 Wh/km.
Set a daily home limit of 80%, which still provides about 415 km of range. The i7's large battery makes the cost difference between home and public charging especially pronounced. Keep public fast charging for road trips, and when you use it, the i7's flat charging curve up to 80% keeps stop times reasonable.
