How fast EV charging stations are to fill up an electric vehicle’s battery depends on the power source they’re wired into and the voltage level they can supply via their connector cables. The actual time it takes to charge an EV also depends on the size and condition of a battery and how full it already is, alongside the power supply of the charging station.
Each EV charging station will fall under one of the following categories:
- Slow chargers supply up to 3kW of power and will fill up an EV from empty in around 8 to 10 hours
- Fast stations are available with 7kW or 22kW of power and will take between 3 and 4 hours to fully charge a vehicle
- Rapid units provide voltages upwards of 43kW and will fully charge an EV in 30 to 60 minutes
Fast or rapid charging stations tend to be the best options for businesses, as they have multiple sockets and can charge an EV in the space of typical office hours. It’s important to keep in mind that, as well as providing different levels of power supply, each station will also be compatible with particular types of EV connectors.
