BMW i3 Charging Time and Speed Guide
Complete BMW i3 charging guide covering charging times, speeds, and costs for Level 1, Level 2, and DC fast charging across all battery configurations.
BMW i3 charging times: Level 2 (240V) takes 4-7 hours for a full charge, while DC fast charging reaches 80% in 30-45 minutes. The newer 42.2 kWh battery (2019-2022) takes longer than earlier 22 kWh and 33 kWh versions.
The BMW i3 comes with different battery configurations depending on the model year, affecting charging times and range.
| Model Year | Battery Size | Usable Capacity | EPA Range |
|---|---|---|---|
| 2014-2016 | 22 kWh | 18.8 kWh | 81 miles |
| 2017-2018 | 33 kWh | 27.2 kWh | 114 miles |
| 2019-2022 | 42.2 kWh | 37.9 kWh | 153 miles |

BMW i3 charging times vary significantly based on the charging method and battery size. Here are the complete charging times for each generation.
| Charging Method | 22 kWh (2014-16) | 33 kWh (2017-18) | 42.2 kWh (2019-22) |
|---|---|---|---|
| Level 1 (120V, 12A) | 12-15 hours | 16-18 hours | 20-24 hours |
| Level 2 (240V, 32A) | 3-4 hours | 4-5 hours | 5-7 hours |
| DC Fast (50kW) | 25-30 min (10-80%) | 30-35 min (10-80%) | 40-45 min (10-80%) |
Level 1 (120V, 12A)
Level 2 (240V, 32A)
DC Fast (50kW)
The BMW i3 supports CCS DC fast charging with good charging curve performance, maintaining relatively consistent speeds until higher charge levels.
- •Maximum DC charging speed: 50 kW across all model years
- •Charging curve: Remains relatively flat until 80% state of charge
- •Optimal charging window: 10-80% charge for fastest session times
- •Charging speed tapering: Power reduces significantly after 80% charge
- •Network compatibility: Works with most CCS DC fast charging networks

Daily Charging Strategy
- •Use Level 2 charging at home for daily needs
- •Charge to 80% for daily driving to preserve battery
- •Take advantage of time-of-use electricity rates
- •Precondition cabin while plugged in to save range
DC Fast Charging Tips
- •Arrive with 10-20% charge for optimal speed
- •Stop charging at 80% unless needed for long trips
- •Use BMW's charging station locator for CCS compatibility
- •Monitor charging speed and move if significantly reduced
