Abstract
A first and second charging equipment for charging electric vehicles is wired on a single electrical circuit. Electric current is dynamically allocated to the first and second charging equipment such that the maximum amount of electric current supported by the single electrical circuit is prevented from being exceeded. Dynamically allocating electric current to the first and second charging equipment includes communicating a first and second current limit to a first and second electric vehicle respectively connected to the first and second charging equipment to cause the first and second electric vehicle to limit their current draw to not exceed the first and second current limit respectively. The sum of current being drawn at the first and second current limit does not exceed the maximum amount of electric current supported by the single electrical circuit.
