Abstract

Estimates suggest that there will be between 0.5 and 12.8 million electric vehicles (EVs) on UK roads by 2030. Power grids could overload if large numbers of these EVs are not recharged off peak, between midnight and early morning. This study investigates the recharging patterns of 12 Private, 21 Organization Individual and 32 Organization Pool users over two successive six month periods as part of the Switch EV trials. EVs were monitored using a data loggers and GPS devices. Recharging locations were identified as Home, Work, Public and Other. It was found less than 10% of recharging took place off peak. Work was the most popular location to recharge, and demand peaked between 09:00am and 10:00am. Private individuals peak recharging occurred on an evening at Home, while Organization Individuals users recharged mostly early morning at Work. Organization Pool users recharging peaked at Work, late afternoon. Smart Meters can delay recharging until off peak hours at Home and Work locations. It is recommended that pay as you go access to non-domestic infrastructure is used for individual drivers. This will encourage them to recharge at Home or Work, where Smart Meters can then shift their recharging to off peak.
