The charging time of a Level 2 charger compared to a Level 3 fast charger shows a significant difference in speed and use case:
- Level 2 Charging Time: Typically, Level 2 chargers deliver an AC current between 3 kW to under 20 kW, and they can provide about 10 to 60 miles of range per hour of charging. This usually results in a full charge taking a couple of hours up to overnight, depending on the vehicle’s battery size. Level 2 chargers are commonly used in locations where vehicles remain parked for longer periods—such as homes, workplaces, and multifamily residences—allowing EV owners to recharge conveniently while doing other activities.
- Level 3 Charging Time: Also known as DC fast chargers or “superchargers,” Level 3 chargers operate at high voltages (400 to 800 volts) and deliver direct current ranging from 50 kW to as much as 350 kW. This allows them to add 100 to 200 miles of range in just about 20 to 30 minutes, achieving a full charge in approximately half an hour for most EVs. They are primarily found along highways, busy transportation corridors, and fleet operation centers, where rapid turnaround is critical for drivers needing to resume travel promptly.
Summary Comparison
| Feature | Level 2 Charger | Level 3 Charger (DC Fast Charger) |
|---|---|---|
| Power Output | 3 kW to <20 kW AC | 50 kW to 350 kW DC |
| Charging Speed | 10-60 miles range per hour; 2+ hours for full charge | 100-200 miles range in 20-30 minutes; full charge ~30 minutes |
| Typical Use Case | Overnight/home/work charging | Quick charging on long trips or fleet operations |
| Voltage | 240 volts AC | 400 to 800 volts DC |
In essence, Level 3 chargers are designed for speed and convenience during travel or commercial uses, reducing charging time drastically compared to Level 2 chargers, which cater to longer, stationary charging sessions.
