How does an electric vehicle charging station work?

Before going through the functioning of EV charging and how does an electric vehicle charging station works it’s important to understand some basic things about electric vehicles.

What is an electric vehicle charging station?

An electric vehicle charging station or EV charging station is a place where an electric vehicle gets charged with the help of external chargers known as electrical vehicle chargers.
These electric vehicle chargers are used depending upon the type of vehicle and time required to charge a vehicle.
An EV charging station is categorized into LEVELS describing the power.

Level 1: Level 1 EV chargers are used to provide trickle or occasional supply, where EV charging is connected to a 10 amp or 15 amp socket.

Level 2: level 2 EV chargers are AC chargers and they are 5 times faster than level 1 chargers and these chargers are generally used in homes.

Level3: level 3 chargers are the fastest chargers capable of charging an electric vehicle faster, These are particularly used on highways and busy areas.

Components of electric vehicle:
Battery (all-electric auxiliary): In an electric vehicle, an electric auxiliary battery provides electricity to power electrical accessories.

Charge port: The charge port allows the vehicle to connect to an external power supply to charge the traction battery pack.

DC/DC converter: This device converts the higher voltage dc power from the traction battery pack to lower voltage dc power. This lower voltage dc power is required to run vehicle accessories and recharge the auxiliary battery.

Electric Traction motor: This motor drive the electric vehicle wheels by using the power from the traction battery pack.

Onboard charger:
It takes the incoming AC electricity supplied via the charge port and converts it into DC power to charge the traction battery pack.

Power electronics controller:
This controller manages the flow of electrical energy delivered by the traction battery, controlling the speed of the electric traction motor and the torque it produces.
