BMW i3 Charging Times: What You Need to Know
Charging times vary significantly based on battery capacity, charger type, and battery health. Here’s a comprehensive breakdown:
DC Fast Charging (10-80%)
- Classic BMW i3 (60Ah-120Ah): Approximately 40-60 minutes
- New Generation i3 (Neue Klasse): As fast as 21 minutes with 400kW ultra-fast charging capability
