Abstract
A total amount of current drawn through a first charging equipment and a second charging equipment that wired on a same electrical circuit is limited to not exceed a maximum amount of electric current supported by the electrical circuit to prevent the electrical circuit from being overloaded, where limiting includes communicating a first current limit to a first electric vehicle connected to the first charging equipment to cause the first electric vehicle to limit its current draw to not exceed the first current limit, and communicating a second current limit to a second electric vehicle connected to the second charging equipment to cause the second electric vehicle to limit its current draw to not exceed the second current limit, where a sum of current being drawn at the first current limit and the second current limit does not exceed the maximum amount of electric current supported by the electrical circuit.
