Electric vehicle (EV) chargers work by supplying electric energy to the battery of an electric vehicle. The two main types of EV chargers are Level 1 and Level 2.
Level 1 chargers use a standard 120-volt household outlet and can charge an EV battery in 8-20 hours depending on the vehicle model and battery capacity. They are relatively slow but are easy to use and can be found in many public places.

Level 2 chargers, on the other hand, use a 240-volt outlet and can charge an EV battery much faster, usually in 2-8 hours. These chargers are typically found at public charging stations and can also be installed in homes. They are more powerful than Level 1 chargers and deliver more energy to the battery in a shorter time.

Both Level 1 and Level 2 chargers use a device called an "EVSE" (Electric Vehicle Supply Equipment) to control the flow of electricity to the vehicle. The EVSE communicates with the vehicle to determine the appropriate charging rate and manages the charging process to ensure that the battery is charged safely and efficiently.
There are also Level 3 chargers, known as DC fast chargers, that can charge an EV battery up to 80% in under an hour. These chargers use high voltage DC power and connect directly to the battery, bypassing the on-board charging equipment. DC fast chargers are typically found at highway rest areas, service stations and other high-traffic areas.
In summary, EV chargers work by supplying electricity to the battery of an electric vehicle, and the rate of charge depends on the level of charger. Level 1 chargers use a standard household outlet and are relatively slow, Level 2 chargers use a 240-volt outlet and are faster, and Level 3 chargers use high voltage DC power and are the fastest of all.
