What is the charge current that Level 2 EVSEs with a rating of 6.6 kilowatts can supply at 220 VAC?

To determine the charge current supplied by a Level 2 EVSE (Electric Vehicle Supply Equipment) rated at 6.6 kilowatts operating at 220 VAC, the relationship between power (in watts), voltage (in volts), and current (in amperes) is given by the formula:

Power (W) = Voltage (V) × Current (A)

Rearranging this to find the current gives us:

Current (A) = Power (W) / Voltage (V)

Using the given values:

• Power = 6.6 kW = 6600 W

• Voltage = 220 VAC

Now, substituting in the values:

Current (A) = 6600 W / 220 V = 30 A

This calculation shows that the charge current that a Level 2 EVSE with a rating of 6.6 kilowatts can supply at 220 VAC is indeed 30 A. This is consistent with the expected characteristics of Level 2 charging, which typically supports this level of current.
