Master-Slave Control Scheme in Electric Vehicle Smart Charging Infrastructure

Abstract

WINSmartEV is a software based plug-in electric vehicle (PEV) monitoring, control, and management system. It not only incorporates intelligence at every level so that charge scheduling can avoid grid bottlenecks, but it also multiplies the number of PEVs that can be plugged into a single circuit. This paper proposes, designs, and executes many upgrades to WINSmartEV. These upgrades include new hardware that makes the level 1 and level 2 chargers faster, more robust, and more scalable. It includes algorithms that provide a more optimal charge scheduling for the level 2 (EVSE) and an enhanced vehicle monitoring/identification module (VMM) system that can automatically identify PEVs and authorize charging.

Reducing Range Anxiety by Unifying Networks of Charging Stations

“…Although the charging process mostly happens during the night at home or in parking lots during the day, availability of public charging stations is an important factor in penetration of EVs [1], [6], [9]. Therefore deployment of widely distributed networks of fast charging stations will provide flexibility to EVOs in planning long trips [4], [5], [12], [17]- [30].…”

“…Availability of this infrastructure is a key factor in general acceptance of Electric Vehicles (EV) [1]- [3]. The lack of CI as well as recharging time of an EV together with its limited range may discouraged many drivers from switching to EV [4], [5] and will lead to "Range Anxiety".…”

“…Range anxiety can be considered as another impact on market acceptance of EVs [7], [8]. Therefore, availability of public CI is an important factor in penetration of EVs [1], [5], [6], [9].…”

“…The data returning from EV through Charge Point (CP) can be used for monitoring, scheduling, energy distribution controlling during peak hours, and managing the energy consumption during offpeak hours. Therefore, a universal charging platform which is reliable and available in both public and private spots will accelerate user acceptance of EVs [1], [6], [9].…”

Design and development of electric vehicle charging station equipped with RFID

“…The need for clean environment promoted the development of green car technology such as electric vehicles (EV) [1][2][3][4]. Thus the demand of plug-in electric vehicles (PEVs) charging for public vehicle charging system is increasing.…”
