DC Fast Charging vs. Level 2 Charging: Speed Comparison
Overview of Charging Methods
- Level 2 Charging: This uses alternating current (AC) and operates at 240 volts. It is commonly used for home charging and public stations because it provides faster charging than Level 1. Level 2 chargers can range from about 3 to 19.2 kW in the U.S. and up to 22 kW in Europe. They typically add between 12 and 32 miles of range per hour of charging, depending on the charger’s power output and the vehicle’s capabilities.
- DC Fast Charging (Level 3): This uses direct current (DC) to charge vehicles much faster than Level 1 and Level 2. DC Fast Chargers can deliver significantly higher power outputs, often ranging from 50 kW to over 350 kW, allowing for the rapid replenishment of an electric vehicle’s battery to 80% in about 30 minutes or less.
Speed Comparison
- Level 2 Charging Speed:
- Typical Range Gain: 12 to 32 miles per hour of charging.
- Full Charge Time: Can take several hours; for example, a 19.2 kW charger might fill a 40 kWh battery in about 2.1 hours.
- DC Fast Charging Speed:
- Typical Range Gain: Much faster, potentially adding hundreds of miles in under an hour.
- Full Charge Time to 80%: Generally achievable in 30 minutes or less for many models.
In summary, DC Fast Charging is significantly faster than Level 2 charging, providing rapid top-ups for long-distance travel, while Level 2 charging is more suited for longer-term charging at home or in public stations where time is not as critical.
