BMW released some of the findings of a study conducted with University of California – Davis yesterday about how participants in the Mini E test program adapted to their small electric vehicles ( EVs). The BMW message was totally upbeat – the headline was "Mini E Drivers Delighted with Electric Vehicle Experience" – but the reality isn't quite as positive as BMW made it sound. Read more on that here.
At the Washington Auto Show, though, the message was pretty much all good, all the time. One of the biggest complaints about EVs is their limited range. BMW found, though, that the Mini E's range (officially given as 100 miles, but it varies in the real world between 70 and 100) were "sufficient for most trips." The drivers got used to planning their drives with the limit in mind, said Rich Steinberg, manager of electric vehicle operations and strategy for BMW of North America. Part of getting used to the Mini E, Steinberg said, was becasue the drivers have fun in their EVs (i.e., what some people call the EV grin). In fact, the cars worked so well that, once they had the Mini E, the participating households said they used it for 90 to 100 percent of vehicle trips. In fact, all respondents said that they didn't use their other vehicles as often one the Mini E was available to them (see, again: EV grin). Read on past the jump for more.

So, who are the respondents? Of the 450 Mini E drivers in the world, UC – Davis got detailed with 57 self-selected participants. BMW also interviewed some German Mini E drivers and found there were differences between how they recharged their vehicles and how the Americans did. Steinberg said that most American drivers plugged in the car as soon as they got home, no matter how far they drove. Most Germans, on the other hand, only recharged when they actually needed to, when the car was low on energy. In either case, Steinberg said charging is not a big issue with these early adopters, "even without an extensive network of public charging stations."
Of course, the remaining key issue with the Mini E is that there's no room for a lot of cargo or more than two people. The company's ActiveE, which was displayed prominently on the stand, eliminates these problems. As reported, a field trial program for the ActiveE similar to the Mini E leases will start in 2011. BMW will use data from both of these programs to build their Project i Mega-City Vehicle, coming who knows when.
MINI E Drivers Delighted with Electric Vehicle Experience
* Press Release
UCDavis study shows participants enjoy driving MINI E. Feedback sets stage for next phase of BMW Group Mega-City Vehicle initiative
Woodcliff Lake, NJ – January 26, 2010 12:55pm EST... The BMW Group today announced at the Washington Auto Show the first results from a comprehensive study conducted in cooperation with the University of California (UC Davis) and consumers leasing MINI E electic vehicles as part of a year-long program to acquire real world use patterns. The MINI E program is the first large population field test of current generation electric vehicles and therefore sheds a realistic light on both the opportunities and challenges from this innovative new form of mobility.
The UC Davis study results of 57 drivers, combined with updates continually provided from the log books of all 450 users show the following:
* The range of about 100 miles is sufficient for most daily needs
* Charging at home provides enough energy for most daily driving
* Demand for additional charging is centered on the place of work, or where sufficient time is spent during the day (shopping centers, stadiums, etc.)
* Driving the MINI E is a delightful experience and there is no sacrifice of "real car" values
* Unmet demands focus on having enough space for four passengers and more cargo to stimulate even more use of an electric vehicle
"There's been a lot of conjecture about electric vehicle user demands and being the first to the market with obtaining 'real world use' patterns, we're now able to shed some accurate light on this subject," said Rich Steinberg, Manager – EV Operations and Strategy for BMW of North America. "What they shared with us is that, for the most part, the MINI E suits their daily driving needs and that they really enjoy driving it. This makes us optimistic that electric vehicles have a role in the future of mobility in America by being a part of the overall vehicle mix."
More than 1,800 people and organizations applied to be part of this ground-breaking field trial of 450 MINI Es now on the road in the US. From that, 450 were selected based on specific criteria that included the amount and type of use in which they would engage, home suitability to installation of a fast charging system and desire to be engaged in a field trial that requires continual feedback.
MINI E drivers provide ongoing feedback that has already proven invaluable to the development work being done by the BMW Group's Project i on what is called a Mega-City Vehicle – the company's innovative program to develop a volume transportation solution to the demands of the world's biggest cities in the 21st century. This vehicle is scheduled to be introduced just before the mid-point of this decade.
The self-selected group of 57 that agreed to participate in the UC Davis survey is part of a more extensive research project. Feedback from this program shows that the range of the MINI E enables drivers to use it for most daily driving needs. Reported range under normal circumstances varies between 70 – 100 miles with 45 percent reporting a typical range of 100 miles. MINI E drivers reported an average trip length of approximately 30 miles. Other studies have found that driver's in the US average about 40 miles per day1. This makes the range of the MINI E suitable for most daily driving needs.
Many households in the study have replaced the primary vehicle of one driver with the MINI E. One-third of the participants have reported driving the MINI E even more than the household vehicle it replaced. The lack of a back seat and a usable trunk, rather than range, is most often the reason the MINI E is not chosen for a particular outing.
Drivers have also reported that driving the MINI E is fun. Most adapted quickly to the characteristics of the Brake Energy Regeneration function and like the feeling of control it gives them in being able to proactively extend the range of their MINI E by how they drive. Brake Energy Regeneration captures energy ordinarily lost on deceleration and coverts it into electrical energy to recharge the batteries. All drivers in the US study said they enjoy using one pedal to accelerate and decelerate. Many reported that once they became acustomed to the BER function, they enjoyed driving their conventional vehicles less.
The study found that keeping the MINI E charged did not pose a problem. Recharging in the US requires four – five hours and, while it wasn't always necessary based on their driving needs, about half of the drivers in the study report recharging daily as a matter of routine. Additional recharging away from their home charging station by-and-large proved unnecessary.
This first field-trial has provided Project i with invaluable insight as it prepares for its second field trial with the BMW ActiveE. The electric drivetrain developed for the BMW ActiveE will be used in the BMW Group's first Mega-City Vehicle. The newly developed and more compact lithium-ion battery pack in the BMW ActiveE vehicle features liquid heating and cooling in order to provide a more consistent and predicatable driving range. Smartphone apps will enable the user to remotely check the available range of the BMW ActiveE's battery. The apps will also enable the driver to begin heating or cooling the interior of the BMW ActiveE and thus the battery while still connected to the grid. This will allow the battery to function at its optimal operating temperature without affecting the range of the car.
The field trial for the BMW ActiveE will begin in 2011. As announced at the North American International Auto Show earlier this month, lease extensions will be offered to a number of MINI E drivers who wish to continue their electric driving experience until the BMW ActiveE becomes available.
