1.1 AC Charging Station

A Level 1 EVSE uses commonly-available 120 VAC/230 VAC power sources, draws current in the order of a 12 A to 16 A range and can take anywhere from 12 to 17 hours to fully charge a 24-kWh battery. L1 chargers can go up to a maximum power of 2 kW and is used in residential applications. A Level 2 EVSE (typically used in commercial spaces such as malls, offices, and so forth) uses poly-phase 240 VAC sources to power a more robust vehicle charger and draws anywhere between 15 A and 80 A to completely charge a 24-kWh battery in about eight hours (power level up to 20 kW). Figure 1-1 shows a typical block diagram of an AC charging station.
