Design of a Smart DC Partial Refueling Facility for Electric Vehicles
for Urban Motorways
Abstract
An abrupt increase in the EV population will cause the concomitant
installation of EV charging facilities. Installation of a
full-functional EV charger in every required place is difficult as it
requires a lot of planning and other resources. Partial chargers are the
perfect choice for places where the land and other resources are
limited. This will assure perfect intermittent connectivity and reduce
the driver’s anxiety problem. This project aims at building a DC Partial
Charging Facility (DCPCF) to be conveniently built on urban road sides,
hotels, parking lots, etc. Three important requirements are being
considered for the product development: cost effectiveness, energy
efficiency, and user friendliness. The Smart partial Charger operates in
three different modes, namely, the Fixed Price Mode (FPM), the Fixed SOC
Mode (FSM) and the Advanced Distance Mode (ADM). In the FPM, the charger
charges the customer’s vehicle with the number of units corresponding to
the prepaid amount, whereas in the SOC mode and distance mode, the EV is
charged with energy required to achieve a particular value of SOC or
range. Smart charging policies are devised for the three charging modes,
and an intelligent controller keeps track of the entire system dynamics
and ensures reliable operation of the system. Simulation results proves
the effectiveness of the system.
