Most electric cars come with a 110v Level 1 EVSE for charging.
Some may include a unit capable of more efficient Level 2 charging.
Regardless of whether you need to buy a Level 2 EVSE or got one included with your electric car, to make use of Level 2 charging you will at the very least need to pay for the associated electrical installation to support it.

Can the more efficient Level 2 charging save you enough money to pay for it?
