Comparing Charging Speeds: Level 1 vs. Level 2 EV Chargers
Charging Speed and Time
- Level 1 Chargers: These chargers use a standard 120V AC outlet and are commonly found in most homes. They provide about 1.2 to 1.3 kW of power, adding roughly 2 to 5 miles of range per hour. Charging a battery-electric vehicle (BEV) from empty to full typically takes between 40 to 50 hours, while plug-in hybrid electric vehicles (PHEVs) can charge in about 5 to 6 hours.
- Level 2 Chargers: These chargers operate on a 240V AC supply (or 208V in some commercial settings) and deliver between 3 kW to under 20 kW, depending on the model. They add about 10 to 20 miles of range per hour. Full charging of a BEV usually takes between 4 to 10 hours, while PHEVs can reach full charge in about 1 to 2 hours.
Efficiency and Practicality
- Level 1 Chargers have lower efficiency, often around 80%, making them less efficient compared to Level 2 chargers.
- Level 2 Chargers offer higher efficiency, typically around 90%, which means they waste less energy during charging. They are more suitable for frequent use and are commonly installed in homes, workplaces, and public spaces due to their faster charging times.
Typical Locations
- Level 1 Chargers: Primarily used in residential settings where faster charging is not essential.
- Level 2 Chargers: Often used in homes with dedicated charging stations, workplaces, and public charging areas.
In summary, Level 2 chargers provide significantly faster charging compared to Level 1 chargers, making them ideal for regular use in both residential and commercial settings.
