Electric cars are becoming more and more popularWith the rise of electric cars, EV charging stations are also on the rise.An EV charging station is a device that can charge an electric car batteryThese stations come in two different types: Level 1 and Level 2 chargers:
- Level 1 chargers plug into an outlet and charge a car battery at about 3 miles per hour.
- Level 2 chargers plug into an outlet but require 240-volt power to charge a car battery at about 20 miles per hour .
Electric vehicles have been one of the most important developments in the automotive industryThe introduction of new technology, however, brings new challengesOne such challenge is how to charge an EV quickly and efficiently.
In order to charge an EV as quickly and as efficiently as possible, it is important to understand the basics of how charging worksAll EVs are charged using power from a power grid that must be converted into AC or DC current before it can be usedthe vehicleThe power grid converts AC current from its source (typically a central station) into DC current for useEVs through electric vehicle service equipment (EVSE)Typically, this conversion takes place at home with a Level 1 charger or at work with a Level 2 charger.
To charge an EV, the power is first drawn from the power grid into a charging stationThe current is then converted to ACan electric vehicle service equipment that’s plugged into the wallThis AC current is then sent to a Level 1 charger (or directly to the battery)The Level 1 charger supplies low-voltage direct current (DC) to the battery.Level 2 chargers (also called “DC Fast Chargers”) supply AC current and are capable of delivering up to 300 kWLevel 2 chargers use a transformer to convert the electricity from AC to DC, which can be sent directly into a battery packThe power is supplied at 200-kW or 400-kW
