>Depending on the source of power charging an EV, it could take days or mere minutes to significantly charge a battery. EV charging stations are typically categorized as either level 2 or level 3; however, even an outlet at home will charge your EV (albeit rather slowly). You can expect a home outlet (sometimes called a level 1 charger) to take around 40 hours to fully charge a typical EV.

>Level 2 chargers decrease time significantly: Most can deliver about 15-25 miles of range per hour, meaning that most EVs can be charged either overnight or during a typical work day. These are a great option to have at work or home.
>
>Level 3 is where speed is really ramped up, and there is a wide range of power output for level 3 chargers. These chargers utilize direct current (DC) power and cost a lot more money than other charging stations, so they are typically implemented in public charging infrastructure. Some level 3 chargers can top up an empty battery in as little as 30 minutes. Many are already designed to output much more power than current EV batteries can receive, so the future looks bright for extremely short charging times.
