EV charging station infrastructure refers to the network of charging stations that provide EV owners with a place to charge their vehicles. This infrastructure is critical for the widespread adoption of EVs.
Professionals often refer to the EV charging station as EVSE, which stands for "Electric Vehicle Supply Equipment".
EVSE refers to the equipment and infrastructure needed to supply electricity to an electric vehicle for charging.
There are several types of charging stations that exist, each with its own charging rate and compatibility with different types of EVs. Here are some of the most common types:
LEVEL 1 CHARGING
Level 1 charging uses a standard 120-volt household outlet, AC plug. This type of charging is the slowest. Level 1 charging typically has a power rating of up to 2.4 kW.
LEVEL 2 CHARGING
Level 2 charging uses a 240-volt outlet. This type of charging delivers a charging power of up to 22kW. Level 2 charging stations (AC) are popular for both public and private use. They can be found in various locations, such as parking garages, workplaces, hotels, and grocery stores. Many EV drivers opt for installing a Level 2 charger at home, as it enables them to fully charge their car overnight.
DC FAST CHARGING
Some refer to it as "level 3 charging." DC fast charging uses a high-voltage direct current (DC) connection to deliver a high level of charging power, ranging typically from 50 kW to 350 kW. It can usually charge an EV to about 80% in about 30 minutes.
It's always a good idea to check your car's manual to see what type of charging it requires and to make sure the charging station you plan to use is compatible.
