How it Works

How does ev charging work?

Level 1


While it’s the most basic option, it’s useful for overnight charging at home or in emergencies when a faster charger isn’t available.

For a 90 kWh battery:
Slowest charging rate: 90 kWh battery capacity * 1 hour/5 miles = 18 hours
Fastest charging rate: 90 kWh battery capacity * 1 hour/2 miles = 45 hours

Level 2

Level 2 chargers are commonly found at workplaces, public charging stations, and some residential settings. They’re ideal for daily charging needs, such as during work hours or while running errands.

For a 90 kWh battery:
Fastest charging rate: 90 kWh battery capacity * 1 hour/60 miles = 1.5 hours
Slowest charging rate: 90 kWh battery capacity * 1 hour/10 miles = 9 hours

Level 3 (DC Fast Charging)

DC fast chargers are crucial for long-distance travel and times when you need a quick recharge. They’re commonly found along highways and major routes for convenient pit stops during road trips.

Calculation not provided as DC fast charging does not typically require hours to fully charge due to its rapid charging speeds.
