As electric vehicles (EVs) continue to gain popularity, it’s important to meet the growing demand for EV charging stations. EV charging infrastructure can be classified into three main categories: Level 1, Level 2, and Level 3. Each level of charging requires a different level of infrastructure and power supply. This blog post outlines the different infrastructure required for Level 1, 2, and 3 charging stations.
Level 1 charging is the simplest and most basic level of EV charging. It is often used in residential settings and requires a standard 120-volt AC household outlet. Level 1 charging typically delivers 2-5 miles of range per hour of charging, making it the slowest charging option. However, it is the most accessible and affordable option for businesses.
For businesses, Level 1 charging infrastructure requires a simple installation process that involves the installation of a dedicated electrical circuit and an outlet near the parking area. An experienced electrician can perform this installation, and no additional equipment or hardware is required.
Level 2 charging is the most common level of EV charging for commercial and public spaces. It requires a 240-volt AC power supply, like what is used for an electric dryer or stove. Level 2 charging delivers 10-20 miles of range per hour of charging, making it a more practical option for businesses than Level 1 charging.
To install Level 2 charging stations, businesses need to have a dedicated electrical circuit and a higher capacity electrical service than what is required for Level 1 charging. Additionally, you will need to install an EVSE (electric vehicle supply equipment), which is the charging station itself. EVSEs come in a variety of configurations, including wall-mounted units or free-standing pedestal units.
Level 3 charging is the fastest and most powerful level of EV charging. It is also known as DC fast charging and requires a high voltage DC power supply, typically around 480 volts. Level 3 charging delivers 60-80 miles of range per hour of charging, making it the most efficient charging option.
Installing Level 3 charging infrastructure is the most complex and expensive option for businesses. It requires a large amount of power and a significant investment in equipment and infrastructure. The installation process requires a high voltage electrical service, a dedicated transformer, and a specialized charging station.
Charging times for each level of charger station
Each level of EV charging requires different infrastructure and power supply. Additional considerations include your budget (incentives, rebates, and tax deductions are available), the demand for EV chargers at your location (accounting for the growth of demand over time), and the setup of your parking lot(s).
