LONDON: Electric Nation, which is the largest smart charging trial in the world, has completed the process of collecting charging information from almost 700 trial participants over a period of 18 months, with data from more than 140,000 charging transactions.
The Electric Nation trial took place in the WPD network areas in the Midlands, South West and South Wales.
The trial recruited 673 plug-in EV drivers who represented a cross-section of plug-in vehicle types, with over 40 different makes and models of EVs taking part, including plug-in hybrids and fully electric vehicles, and a selection of battery sizes.
Initial findings show that on average, vehicles are plugged in for over 12 hours, but they are rarely charging for the full time.
Other conclusions from the project suggest that the average charging event starts with the battery already more than 50% full and EV owners only charge their EVs three times a week.
Analysis suggests that there is likely to be sufficient flexibility to manage charging away from peak electricity demand periods.
