- Level 2 Charging: Common in homes, offices, and public locations, Level 2 chargers use a 240-volt outlet and can add around 20-30 miles of range per hour. This level strikes a balance between speed and battery longevity for most drivers.
- Direct-Current (DC) Fast Charging: These are the superchargers you’ll find at public stations and on major travel routes, offering the fastest charging speed by far, adding up to 90 miles of range in just 30 minutes. However, these chargers are best used for long trips rather than everyday charging, as frequent fast charging can accelerate battery wear.
How Long Does It Take To Charge an Electric Vehicle?
The time it takes to charge an EV depends on several factors, including the size of the battery, the current battery level, and the charging level being used. As a rule of thumb, you’re looking at anywhere from 8-12 hours on a Level 1 charger, 3-5 hours on Level 2, and just 30 minutes for a meaningful boost with DC fast charging.
