An EV charger is an essential piece of infrastructure that supplies electric energy to recharge electric vehicles. These units, formally known as electric vehicle supply equipment (EVSE), come in three main levels: Level 1 chargers use standard household outlets and are slow; Level 2 chargers are commonly installed in homes and public spaces, providing much faster AC charging via a 240V connection; and Level 3 or DC fast chargers are found at commercial charging stations along major travel routes, capable of rapidly charging a battery to 80% in under an hour. Choosing the right charger involves considering factors such as charging speed, vehicle compatibility, installation requirements, and smart features like scheduled charging to leverage off-peak electricity tariffs.
