  In this paper, we design a pricing framework for online electric vehicle (EV)
parking assignment and charge scheduling. Here, users with electric vehicles
want to park and charge at electric-vehicle-supply-equipment (EVSEs) at
different locations and arrive/depart throughout the day. The goal is to assign
and schedule users to the available EVSEs while maximizing user utility and
minimizing operational costs. Our formulation can accommodate multiple
locations, limited resources, operational costs, as well as variable arrival
patterns. With this formulation, the parking facility management can optimize
for behind-the-meter solar integration and reduce costs due to procuring
electricity from the grid. We use an online pricing mechanism to approximate
the EVSE reservation problem's solution and we analyze the performance compared
to the offline solution. Our numerical simulation validates the performance of
the EVSE reservation system in a downtown area with multiple parking locations
equipped with EVSEs.
