Abstract:
A first and second charging equipment for charging electric vehicles share a current capacity. A controller coupled with the first and second charging equipment limits a total amount of current drawn through the first charging equipment and the second charging equipment to not exceed the current capacity. A first and second current limit is communicated to a first and second electric vehicle respectively to limit the current draw of first and second electric vehicle to the first and second current limit respectively. A sum of the current drawn at the first and second current limit does not exceed the current capacity.
