  The anticipated increase in the number of plug-in electric vehicles (EV) will
put additional strain on electrical distribution circuits. Many control schemes
have been proposed to control EV charging. Here, we develop control algorithms
based on randomized EV charging start times and simple one-way broadcast
communication allowing for a time delay between communication events. Using
arguments from queuing theory and statistical analysis, we seek to maximize the
utilization of excess distribution circuit capacity while keeping the
probability of a circuit overload negligible.
