British Government Gives The Go Ahead for MINI E
Trial.
The British government body that exists to promote business
innovation in technology announced yesterday that a consortium led
by BMW Group will be supported by a proportion of a £25m fund,
enabling the MINI E to be introduced and tested on British roads by
a mixture of private, corporate and public sector drivers before
the end of 2009.
BMW Group’s successful application to the UK Government’s
Technology Strategy Board followed an invitation for proposals
outlining innovative, industry-led collaborative research projects
involving ultra-low carbon vehicles. The objective of the
Technology Strategy Board is to encourage manufacturers to develop
ultra-low carbon vehicles that customers want to buy and bring them
to market as rapidly as possible.
MINI E models will be on UK roads for a twelve-month field trial
that will evaluate the technical and social aspects of living with
an all-electric vehicle in a real world environment. This year-long
project will play an important part in informing future strategic
and technological decisions.
BMW Group is bringing together an energy infrastructure provider
and an academic partner, with the support of a regional development
agency and local authorities, to make the MINI E research project a
reality in the UK.
The MINI E UK Research Consortium, of which BMW Group is the lead
partner, comprises several organisations which are based around
Oxford and the South-East of England. All will play important roles
in the collaborative field trial. In addition to the BMW Group, the
consortium includes an electric energy and infrastructure provider
(Scottish and Southern Energy), an academic partner (Oxford Brookes
University’s Sustainable Vehicle Engineering Centre) and the South
East England Development Agency (SEEDA) as well as Oxford City
Council and Oxfordshire County Council.
Scottish and Southern Energy, the UK’s leading generator of energy
from renewable sources, will be responsible for providing the
infrastructure in and around Oxford and other locations in the
South-East of England by installing the private and public charging
points that will be required to recharge the batteries in the MINI
E test vehicles.
Oxford Brookes University, under the direction of Professor Allan
Hutchinson who leads its Sustainable Vehicle Engineering Centre,
will be responsible for undertaking scientific data analysis as
well as conducting customer surveys to capture the subjective
feedback from users of the MINI E test vehicles.
At the end of the trial, a comprehensive report documenting the
main findings of the MINI E research project will be published.
This will help inform those bodies seeking to create the political,
technical and commercial framework necessary to enable sustainable
mobility in a low carbon future to become reality.
Electric mobility is just one of the low carbon technology options
being investigated by BMW Group. The company aims to begin series
production of all-electric vehicles before the middle of the next
decade as part of the company’s Strategy Number ONE.
The passion to provide sustainable individual mobility for its
customers is at the heart of BMW’s long-term strategy and has been
for many years. Since 1995, the average CO2 emissions from its cars
has reduced by 25 per cent through a variety of technological
innovations, most recently encompassed by the Efficient Dynamics
programme.
The company and its products have won many awards for this work,
including World Green Car of the Year in 2008 for the BMW 118d. The
development of all-electric vehicles is a vital element of the
future plans for the company.
Andy Hearn, General Manager at MINI UK, said: “It makes perfect
sense for us to undertake a research project in MINI’s home country
and I’m delighted that the Technology Strategy Board will be
supporting our investment and the collaborative activities of our
consortium members.”
“The research results we obtain will help inform those bodies
seeking to create the political, technical and commercial framework
necessary to enable sustainable mobility in a low carbon future to
become reality. They will also give our own engineers a clearer
picture of customers’ requirements and aspirations as they develop
an electric vehicle for series production.”
With 12-month research projects already underway in North America
and Germany, BMW Group will be trialling the MINI E in its three
largest markets by bringing the vehicle to the UK for similar test
purposes.
The MINI E’s electric drive train produces a peak torque of 220 Nm,
and power is delivered to the front wheels via a single-stage
helical gearbox. This unique engine and transmission arrangement
powers the MINI E seamlessly to 62 mph in 8.5 seconds and on to an
electronically-limited top speed of 95 mph. Based on the current
MINI Hatch, the car is available as a two-seater. With 204 hp at
the driver’s disposal, performance is close to that of the MINI
John Cooper Works.
The space normally inhabited by rear passengers is reserved for a
lithium-ion battery. The heavy-duty battery delivers its power to
an electric motor which is mounted transversely under the MINI E’s
bonnet. This power unit is able to unleash its full thrust from a
dead standstill and is complemented by its dynamic deceleration
potential, which is directly coupled to the accelerator
pedal.
The MINI E’s lithium-ion battery can be plugged into all standard
power outlets. Its charge time is strongly dependent on the voltage
and amperage of the electricity flowing through the grid. As with
existing research projects in the USA and Berlin, users will be
able to recharge a battery that has been completely drained within
a very short period of time using a wallbox that will be supplied
as standard with every MINI E. With 240V/32A, charging time for the
car will be around four hours. There is also an intention to
establish a network of public charging stations.
The wallbox will be installed in the customer’s garage, enable
higher amperage and thus ensure extremely short charging times.
Wallboxes fully recharge batteries in just four-and-a-half hours.
Only lockable garages or similar buildings will qualify as suitable
power stations for the MINI E.
Besides the benefit of zero-emissions driving, the MINI E offers
significant economic advantages over a vehicle powered by a
conventional internal combustion engine. Fully re-charging the
battery using off-peak electricity at current prices will cost
around £1.50. Using higher-rate daytime electricity, the cost will
still be less than £4.00.
The MINI E’s 1,465 kilograms is evenly distributed across the car.
Modifications to the suspension system and the car’s Dynamic
Stability Control (DSC), adapted to the car’s specific wheel loads,
ensure safe and dynamic handling typical of MINI.
Production of all cars for the UK trial is underway at the
company’s Oxford and Munich sites. MINI’s Plant Oxford will be
responsible for manufacturing the entire vehicle on the standard
production line, with the exception of the drive components and the
lithium-ion battery. The vehicles will then be transferred to a
specially equipped manufacturing facility situated on BMW plant
premises in Munich where the electric motor, battery units,
performance electronics and transmission will be integrated.
We still have a long way to go before the MINI E is truly ready for
mass production. There are issues such as limited driving ranges,
battery technology costs, relatively lengthy charging times and the
lack of public and private infrastructure of charging stations
which are limiting factors. In addition, the production of “green”
electricity needs to be secured on a larger scale. So for now, the
MINI E will continue its Field Trial, with a selection of eager
applicants testing the car in everyday life. Whilst unable to
participate in the Field Trial, one of our Marketing Executives
recently went over to BMW USA, she ‘just happened’ to see the MINI
E there!
