MINI publishes result of "most in-depth EV trial so far"
An enormous amount of data was collected electronically by data-loggers in the car and the home charging points, and also from extensive driver research carried out by Oxford Brookes University.
Interestingly, the UK average daily distance driven for private cars overall is less than 25 miles. With information gathered by on-board data-loggers, the average single trip distance was recorded as 9.5 miles compared to the UK average of seven miles.
Four out of five people reported that 80 percent of their trips could be done exclusively in the MINI E, and this increased to 90% of users saying that with the addition of rear seats and a bigger boot, all their trips could have been done in the MINI E.
Given the daily driven distance of just under 30 miles, the drivers felt confident enough not to have to charge their MINI E every night. In fact, the average was 2.9 times a week according to information fed back via electricity smart meters, with special night-time tariffs successfully encouraging individual drivers to charge when it was cheapest, which coincided with a low demand period and a greater proportion of renewable energy in the grid mix.
Nine out of ten drivers told the researchers that charging actually suited their daily routine, with 81% agreeing with the statement ‘I prefer to plug in the car than go to a fuel station’. The running cost-savings were appreciated by users, with one participant telling researchers the thing she’d miss most was: ‘the money I will have to start paying for fuel again!’
Most charged at home, with 82 percent using their wall-mounted charging box 90 percent of the time. The lack of a comprehensive public charging infrastructure in the UK was noted, with four out of five participants (82%) saying they thought that it was “essential” that a network of charging points was established. However, almost three quarters (72%) said they were able to use their car perfectly adequately right now as they had access to private charging.
Asked about their driving experience, the trial participants were full of praise. Every single one enjoyed the quietness, with one user quoted as saying: ‘I like the silence – it’s very futuristic and it causes a reaction when people notice you pull away without making a sound.’ And they all agreed with the statement: ‘electric vehicles are fun to drive.’ The reason was partly down to the “fast pick-up and quick acceleration” of the 204hp MINI, again a statement that 100% of those taking part agreed with. One even went so far to say it was ‘absolutely the best car I have ever driven.’
Driving efficiently to extend the range was seen as part of the enjoyment rather than a chore. Understanding that use of the regenerative braking could increase the range by approximately 15%, three quarters of the users (74%) agreed with the statement that it was ‘a game for me to use the regenerative braking in a way that enables me to reach my destination without draining the battery.’
Asked by the Oxford Brookes University researchers for suggestions to deal with the potential danger from the low noise at low speeds, over half (56%) said that instead of an artificial noise, the driver should pay more attention. However just over a quarter (28%) said they’d like to have a warning noise below 12.5mph.
Almost all participants (96%) said they’d consider buying an electric car as a result of taking part, and around half (51%) revealed they would pay a third more for an EV. A third (30%) said they would consider taking the plunge within a year, while 55% said that they would wait for two or more years.
The trial found that one week was all that was needed for customers to adapt to the characteristics and peculiarities of driving an EV, such as charging, range, regenerative braking and low noise. However those company car drivers invited to use the MINI E as a pool car on a less frequent basis needed increased training and support during the initial period of vehicle use in order to consolidate their learning.
Fleet use was a big part of the trial with organisations in the UK and in Europe reporting positive feedback from both individual drivers and also fleet managers monitoring the MINI E’s use as a pool car. Those users who swapped out of their regular car reported that the MINI E was fine for 70 percent of journeys made during the working day, while the pool car success rate was even better with between 80-90 percent of regular trips achievable.
The speed of charging was an important consideration for fleet users, while managers also flagged up the need for a clear procedure for the efficient charging of pool vehicles. Companies that participated included Scottish and Southern Energy, Oxfordshire County Council, and Oxford City Council.
Suzanne Gray, general manager of BMW i said: ‘The feedback from the trial has been invaluable in helping our understanding of how people really respond to electric cars and other factors necessary to support electric car drivers. With this information we will be in a strong position to provide a well-rounded product and service proposition to customers of the BMW i3 and to work with other players in the electric vehicle market to make it a successful experience for a new generation of users.’
Kulveer Ranger, Mayor of London's environment director, said: 'Electric driving technology is coming on leaps and bounds, but people naturally still have questions and concerns. Research such as this by BMW Group into real life experiences is invaluable as it debunks some common myths and underscores why electric vehicles are perfect for urban driving. The trial has also demonstrated the importance attached to supporting infrastructure, which is why the Mayor of London has launched Source London to provide a network of charge points that will help to create optimal conditions for electric vehicle use in the UK’s capital.’For more of the latest industry news, click here.
