Design of fair charging algorithm for smart electrical vehicle charging infrastructure

Abstract

Smart charging infrastructure is required to meet the growing demand for Electrical Vehicle (EV) charging from ever more abundant EV owners. WINSmartEV™ is a software based smart charging infrastructure that can monitor, control and manage EV charging. It also can use multiplexing to share scarce charging resources among different EVs plugged in simultaneously. By default WINSmartEV™ uses a round-robin algorithm to schedule charging time between EVs charging on the 120V level one charging device. In order to enhance user acceptance of this technology, charge time allocation fairness is defined and an algorithm to enhance this fairness is proposed.
