1. A method for charging of electric vehicles at Electric Vehicle Service Equipment (EVSE) units, the method comprising:
establishing a minimum power output requirement for individual EVSEs of a total number of EVSEs associated with one or more charging sites;
for the total number of EVSEs, enabling charging at a subset of EVSEs of the total number of EVSEs, according to a first operation mode, wherein a size of the subset of EVSEs is derived from a relationship between an overall load capacity of the total number of EVSEs and the minimum power output requirement;
upon receiving a set of charging requests from a set of electric vehicles:
initiating charging of the set of electric vehicles at the subset of EVSEs if a quantity of the set of electric vehicles is less than or equal to the size of the subset of EVSEs, and
initiating charging of a first portion of the set of electric vehicles at the subset of EVSEs if the quantity of the set of electric vehicles is greater than the size of the subset of EVSEs, with placement of a second portion of the set of electric vehicles into a charging queue.
