Claim 13:
14. An electric vehicle charging control system, comprising:
an electric vehicle charging apparatus positioned at an electrical utility customer site;
an electricity consumption sensor for the electrical utility customer site, the electricity consumption sensor being configured to measure power consumption of the electrical utility customer site;
a control system in electronic communication with the electricity consumption sensor, the control system comprising at least one processor and memory coupled to the at least one processor, wherein the memory comprises machine executable code that, upon execution by the at least one processor, implements a method comprising:
measuring power consumption of a set of electric vehicle charging stations at a site over a time period and a separate set of loads at the site over the time period, wherein the separate set of loads draws power from a power source in common with the set of electric vehicle charging stations;
determining a consumption variation indicator for the power consumption of the separate set of loads and the set of electric vehicle charging stations during the time period, the consumption variation indicator comprising a comparative indicator of the power consumption during the time period and the power consumption during a period preceding the time period;
determining a charging rate for an electric vehicle at the site based on the consumption variation indicator; and
transmitting a signal to at least one of the electric vehicle or an electric vehicle charging station of the set of electric vehicle charging stations, the signal comprising computer-executable instructions to control power draw for the electric vehicle based on the charging rate.
