Electric vehicles are an ‘attractive and viable means of urban transportation’-that’s the unanimous conclusion of participants in the UK’s largest ever public trial of electric vehicles.
As a 27 month study, involving some 110 vehicles and drivers, draws to a close this week, the Coventry and Birmingham Low Emission Demonstrators (CABLED) programme prepares to reveal the details of its findings.
Data from the West Midlands-based trial shows a clear trend in drivers travelling longer journeys over a time – indicating their increased confidence and reduced range anxiety as their familiarity with their vehicle’s capabilities and the location of charging infrastructure grows.
However, in analysing some 640,000 miles driven in the electric models, it was found that most journeys (75 per cent) lasted less than 20 minutes and only 2 per cent used more than 50 per cent of the battery’s charge – demonstrating that for the majority of drivers, who don’t need to cover longer distances, a return journey to be made without the need for recharging.

In relation to charging the electric cars, CABLED data showed that the average charge time was between 2-3 hours. This was an average energy transfer of 5kWh per day, costing around 30-80p (depending upon tariff) which is only slightly more energy than a washer dryer.
Cars involved in the trial included the Nissan LEAF, Mitsubishi i-MiEV, smart fortwo electric, Citroen C1 EV’ie and Tata Indica Vista EV- the last of which has been controversially cancelled for full market launch (see story).
The data also showed that drivers were motivated to recharge whenever convenient, with GPS trackers revealing that the vehicles were parked for over 97 per cent of the time (more than 23 hours each day) -ample opportunity for them to be plugged-in and recharged.
Andrew Everett, Head of Transport at the Technology Strategy Board, said: "While analysis of the eight trials that make up the Ultra Low Carbon Vehicle Demonstrator programme is on-going, CABLED’s examination of driver behaviour, vehicle use and performance shows that people are adapting to electric vehicles and find their use both viable and attractive. Such findings will help to inform and support both future R&D and decisions relating to infrastructure planning by policy makers."
The CABLED consortium is expected to publish a report containing its full findings next month.
