Abstract
This paper quantifies the recharging behaviour of a sample of electric vehicle (EV) drivers and evaluates the impact of current policy in the north east of England on EV driver recharging demand profiles. An analysis of 31,765 EV trips and 7704 EV recharging events, constituting 23,805 h of recharging, were recorded from in-vehicle loggers as part of the Switch EV trials is presented. Altogether 12 private users, 21 organisation individuals and 32 organisation pool vehicles were tracked over two successive six month trial periods. It was found that recharging profiles varied between the different user types and locations. Private users peak demand was in the evening at home recharging points. Organisation individual vehicles were recharged primarily upon arrival at work. Organisation pool users recharged at work and public recharging points throughout the working day. It is recommended that pay-as-you-go recharging be implemented at all public recharging locations, and smart meters be used to delay recharging at home and work locations until after 23:00 h to reduce peak demand on local power grids and reduce carbon emissions associated with EV recharging.

Summary
The Stern Review (2006) highlighted the future economic costs of the impact of climate change. It recommended that greenhouse gas (GHG) emissions need to be cut by 60–80% by 2050, relative to 1990 levels. The King Review was commissioned to investigate ways in which the UK could cut carbon emissions from cars and small vans to meet this target A higher estimate of between 4.6 and 12.8 million pure battery electric vehicles and between 2.5 and 14.8 million plug-in hybrid electric vehicles on UK roads by 2030 was forecast by National Grid (2011b)
