1. A method for charging a plurality of electric vehicles, comprising:
determining a plurality of characteristics of each of the plurality of vehicles, the plurality of characteristics including a charge capacity of a battery system of each vehicle and a mission schedule for each vehicle;
determining a plurality of characteristics of each of a plurality of chargers coupled to an electric power grid, the plurality of characteristics including a type of each charger and a charging capacity of each charger;
processing the plurality of characteristics of each of the plurality of vehicles and the plurality of characteristics of each of the plurality of chargers to identify charging opportunities for each of the plurality of vehicles over the course of a time period;
performing a peak power optimization analysis to generate a vehicle charging profile, the vehicle charging profile configured to activate a minimum number of chargers simultaneously and to minimize downtimes of the plurality of chargers to thereby distribute the power demand from the electric power grid and result in an initial peak power; and
instructing a stationary energy storage (“SES”) device to provide power to one or more vehicle chargers while simultaneously ending a power supply from the electric power grid during the peak demand times, the peak demand times being defined by a sum of the respective power ratings of each of the chargers active at a first portion of a time period relative to one or more second portions of the time period.
