Study: MINI E Meets Daily Needs for 90% of Trial Participants

Ever wonder if an electric car could really work in your daily driving routine? Take heart, a recently released study from UC Davis and BMW Group found that the MINI E met the daily driving needs of 90% of the trial participants. The study also found that 95% of participants drove fewer than 80 miles in a given day. In terms of commuting and even general errand running, this isn’t particularly surprising, but the results are noteworthy because of most people’s so-called “range anxiety.” Read the full summary after the jump.
[Official Release] The University of California, Davis and the BMW Group today released the largest publicly available study of electric-car users ever conducted – including over 120 families who drove the fully electric MINI E automobile more than 1 million miles in California, New York and New Jersey from June 2009 to June 2010. The report shows that the participants found the cars to be fun yet practical, easy to drive and recharge, and many said they would buy an electric car in the next five years, according to UC Davis researchers.
As battery electric vehicles (BEVs) enter the commercial marketplace for the first time, the results of this year-long study by the UC Davis Plug-in Hybrid & Electric Vehicle Research Center provide valuable insight into new ways that consumers value BEVs.
Through online and telephone surveys of the participating households, and diaries and in-person interviews with a subset of more than 40 households, the UC Davis MINI E research team examined user behavior, infrastructure use, costs, environmental benefits, and other aspects of electric driving.
Among the key findings of the study are the following:
By the end of the lease period, MINI E drivers overwhelmingly thought that the electricity for charging their BEV should come from renewable resources such as solar, wind and hydropower, and were strongly opposed to using coal to generate electricity for their vehicles.
The UC Davis study is part of a whole set of studies being conducted by the BMW Group on electric vehicles, which includes research in China, Germany and the U.K.
Compelling combination of “clean and funâ€
UC Davis Plug-in Hybrid & Electric Vehicle Research Center director Tom Turrentine said the study highlights three new and potentially significant ways that drivers value BEVs. First, the MINI E meets drivers’ desire for a vehicle that is both environmentally friendly and fun to drive. Drivers loved the vehicle’s quick acceleration and quiet operation.
“What we heard over and over again in our interviews is how fun it was to drive. That’s in part because it’s a MINI and in part because of the feel of electric drive,†Turrentine said.
Second, drivers find value in using electricity as a fuel and in mastering their individual energy use through efficient driving behaviors. “The combination of limited onboard energy and extreme efficiency make BEVs the premier appliance for people to experience energy use,†says Turrentine. Additionally, the drivers learned to appreciate the car’s powerful regenerative braking function, which returns energy to the battery and allowed them to drive using a single pedal for acceleration and braking.
Third, drivers like to develop their clean driving territory. “Drivers start talking about the MINI E as a special way to explore their region. They of course can go anywhere in their gas car, but they like to talk about where they can go in their MINI E,†Turrentine says.
“Range anxiety†not a big issue for experienced MINI E drivers
While range is often held up as a limitation of BEVs, the MINI E’s range of around 100 miles was acceptable to most drivers most of the time. “We found that households adapted their driving around the capabilities of the vehicle and even explored ways to maximize the use of the MINI E,†said Turrentine.
By studying the MINI E drivers’ usage patterns and need for range, researchers were able to determine that strategic placement of charging stations could allow drivers to reach most of their desired destinations using a BEV that has a range of 90 to 100 miles. Most charging occurred at home, at night, and 99% of respondents said home charging was easy to use.
BMW Group prepares 2nd phase of its EV strategy with BMW ActiveE
“The MINI E studies are extremely valuable for us as they show that electric cars are already today offering an attractive mobility solution to a broader spectrum of customers. While reducing the tail pipe emissions to zero, the MINI E provides the fun that users expect when driving our products. The results of the UC Davis study have a direct impact on the development of all BMW Group electric vehicles to come,†says Ulrich Kranz, head of project i, BMW Group. “BMW Group now is developing the next generation of full electric cars, with the BMW ActiveE test fleet coming into the market in 2011 and the series production BMW i3 following in 2013.â€
The all-electric BMW ActiveE will be available in select US markets beginning in late 2011, for a two-year lease at $499/month, with a $2,250 down payment. Details can be found at www.BMWUSA.com/ActiveE. Join the growing conversation about the future of mobility at www.BMWActivetheFuture.com.

<p>It should be noted that “…met the daily driving needs of 90% of the trial participants.” is not the same as “Respondents said the MINI E met 90% of their daily driving needs.”</p>
<p>Of course any alternative that can moderate fossil fuel dependence is laudable. Ultimately, advanced battery and charging technology will make the alternative considerably more convenient, practical, and cost effective  in terms of providing commuter transit. Conversely, many of us that are thrilled by the spectacle of motorsport may find it far less palatable to experience the near silent whir of electric motors, not to mention our olfactory senses deprived of the scent of trackside racing fuel. Even diesel fumes can be more stimulating than the aroma of an electrical short amidst a pollution-free biosphere!</p>

<p>I see how nuclear power could not even be mentioned in the charging power source list. A year ago it would have been right in the mix. By far the most interesting point of the article. Society is really trying to shift.</p>
<p>Heck, my gas powered MINI only meets about 80% of my driving needs. That’s why we have more than one car! Anyway, it’s not surprising that the respondents were enthusiastic, after all, they were a self selected group of people who liked the technology before they got the car. But it is a nice “existance proof” that electric cars can work for people in real world use situation.</p>
<p>It’s also interesting to note that the lease price on the 1 series electric is going to be lower too… Guess BMW really is learning something!</p>

<p>Actually the future is here, or rather, at MIT. With consumers used to the  convenience of refueling their vehicle at the gas station in a few minutes, one of the biggest disadvantages of electric vehicles is the time it takes to recharge their batteries. Now, by separating the energy storage and energy functions of the battery into separate physical structures, researchers at MIT have achieved a breakthrough that could allow EVs to be recharged in the same time it takes to refuel a conventional car. The new battery employs an architecture known as a “semi-solid flow cell” which sees the battery’s positive and negative electrodes made up of solid particles suspended in a liquid electrolyte AKA “Cambridge Crude.” </p>
<p>But how would we get to The Dragon in it?</p>
