Building on the success of
the "Australian Concept Car" project in 1988, Axcess Australia Projects
Limited, a not-for-profit company established to manage collaborative
projects, has created a car that represents the future in automotive
technology, a hybrid-electric car.
The automotive industry sector and Australia’s national research agency
CSIRO, cooperated in building an exemplary concept car as a means of
creating a high impact and technically credible statement of Australian
industrial capabilities.
The project is an outstanding example of industry cooperation with
Government in cohesively building a case for Australian technological
excellence and competitiveness in one of the world’s most globally
structured industries.
Funds of approximately $12 million from a range of Government and CSIRO
sources combined with an equivalent industry participation to undertake the
creation of the car and to pursue a far ranging, innovative and aggressive
international marketing program lasting 15 months.
More than 80 companies supplied 104 component systems to the car. Another 20
companies supported the project with services such as emission and
engineering testing. All have endorsed the program of marketing activities,
and many have or will accompany the car as it travels overseas on its
mission of promoting component exports.
The marketing plan covers 14 countries, calling at all of the world’s major
carmakers and some of the largest component system integrators. The car has
been displayed at the design headquarters of Korean and Japanese carmakers.
It was shown at Automechanika Frankfurt, the world’s largest show of its
kind and will be exhibited in South-East Asia and finally in the United
States in early 2001. It will also be displayed at high-exposure venues in
Australia.
Awareness of Greenhouse gas emission issues is growing in Australia and
around the world. There is a need to demonstrate that Australia has the
technology and the manufacturing expertise to produce low-emission cars. A
major project goal was to demonstrate to Government that Australia need not
rely on overseas sources for technologies that ameliorate emissions and that
the technologies displayed in the aXcessaustralia project are very
exportable to the global market.
Australian Industry has readily recognised that it needs to be familiar with
emerging technologies. So far the project has completed 24 seminars to
disseminate technological information. The seminars have also been used to
explore the implications for marketing in a rapidly changing global
industry.
Companies worked together in "system groups" to agree on the best technology
and sharing of information that would create the best impact for the common
good. Australia needs this collaborative approach if it is to compete with
the international giants of the industry. A key feature of the project’s
message is that the technologies selected are “production-ready” and
affordable. It was a prime requirement for the project is that the
technologies must be “affordable” – offer high value at competitive prices.
Hybrid-electric cars are already in mass production in Japan and France. For
this project to be credible, the car must be technologically sound and at
demonstrably lower cost than overseas equivalents. This challenge is met
with the unique CSIRO combination of supercapacitors and batteries to
provide a “Surge Power Unit” that is lighter and lower cost than overseas
power packs. Components for the car provided by industry also demonstrate
cost effectiveness because this is vital in penetrating new markets.
The most fundamental underlying aspect of the program however, has been to
present the Australian automotive industry as one displaying engineering
excellence, R&D development capability, cost competitiveness and readiness
to do business.
Many additional benefits have resulted or are promised from the project,
including:
* A marked strengthening of the respect and cooperative relationship between
the car companies operating in Australia and their suppliers.
* A breakthrough in understanding the benefits of collaboration between
Government and industry, and between industry members in pursuing
international business.
* An increased respect for CSIRO as a leading technology provider to
manufacturing industry.
* A reawakening of public belief in the technical competence of its domestic
industry.
* A possible blueprint for how other industry sectors in Australia may
proceed to win new business in an increasingly global market.
None of these benefits and successes could be achieved without the
establishment of a credible and competent engineering base, the
aXcessaustralia Low Emission vehicle itself.
The project builds on the success of the first aXcessaustralia project in
1998, from which more than $700 million of new export business was
generated. An equivalent amount or more is confidently expected from the new
project.
"aXcessaustralia" is a Registered brand name. Design details and engineering
specifications are proprietary to aXcess Australia Projects Limited.
The product is an integration of components designed to promote component
exports. The participating companies individually pursue export contracts
for their components or negotiate licensing arrangements with overseas
companies.
One of the aims of the project is to display to local carmakers that the
component suppliers in Australia are capable of meeting any import
competition. At this time of a weakening Australian dollar, it is important
to maximise competitive local content in locally made cars.
Car importers also recognise that retail price rises caused by a weaker
Australian currency can be partly offset by buying more components in
Australia, for fitment to their cars after arrival or for export to the
overseas assembly operations.
2.10. Product life cycle and environmental considerations
The product offers reduced fuel consumption of more than 50% in city-drive
conditions and 90% reduction of the emissions that cause urban air
pollution.
Because the car itself will not be mass-produced, and will eventually reside
in a museum, environmental considerations for its disposal are not an issue.
However, the components comprising the car were all designed to recognise
the growing demand by carmakers for componentry that can be readily recycled
or re-used.
The external form of the product is relevant inasmuch as it must be
eye-catching to experienced car designers and engineers. The interior of the
car has to be appealing, yet practical and ergonomically attractive because
it is subjected to scrutiny by overseas car designers. The product satisfies
all of these criteria and has been widely praised in specialist magazines.
Aesthetic features are important to the product because of a common
perception that low-emission cars are often small and awkward. The product
has to be appealing to car specialists and also to members of the public
when it is displayed publicly.
The car conforms to all relevant Australian Design Rules for cars and
electrical safety standards.
Packaging a unique powertrain into a conventional car frame was a major
challenge. Initially, it was planned to incorporate the component products
from around 30 companies, but as the project progressed, many more companies
wanted to have their products included. Finally, products from 81 companies
were incorporated into the car.
Technologically, the project is a major challenge. Storing sufficient energy
to complete one U.S. city drive cycle is a major challenge in itself. At the
same time, generating sufficient power for the car to perform equivalently
to a conventional car in terms of acceleration and top speed is a further
challenge. These challenges were all overcome with cooperation between
project managers, constructor and component manufacturers.
The aXcessaustralia Low Emission Vehicle is a hybrid-electric car, an
electric car with the electricity being generated on-board. The car uses
less that half of the fuel of an equivalent conventional car by storing
energy required for acceleration so that the petrol engine needs to operate
less than half of the time. As well, a smaller engine can be used. By
reducing fuel consumption 50%, emissions of “greenhouse gases” (Carbon
dioxide) are reduced 50%.
When the engine operates, it operates for best emissions rather than maximum
power and therefore reduces by more than 90% the emissions that cause urban
air pollution compared with a conventional car.
Hybrid-electric cars are already in production overseas, but they use
high-cost technologies such as exotic batteries (similar to those used in
mobile telephones). The aXcessaustralia Low Emission Vehicle shows that
hybrid-electric cars could be produced for a reasonable price premium that
could be recovered from fuel cost savings in less than two years.
The aXcessaustralia Low Emission Vehicle is a series hybrid-electric car
that uses a novel, Australian, compact internal combustion engine to
generate electricity. The electrical energy is stored in a unique surge
power unit comprising advanced lead-acid batteries and supercapacitors. The
energy management system is unique, maintaining individual voltages of
generator, battery and supercapacitor systems and delivers power to a
three-section, water-cooled, switched-reluctance drive motor. The power
management system enables the car to be driven in normal mode (where the
engine operates according to the position of the accelerator pedal and state
of charge of the storage system), or electric-only mode. The car meets the
most stringent U.S. regulations for emissions. It can operate for one
complete city-drive cycle in electric-only mode. In normal mode in the city
drive cycle its fuel consumption is less than 5 litres per hundred
kilometres.
The car incorporates many novel features in the componentry provided by the
participating companies. For example, the car has three navigation systems
because three Australian companies offer novel navigation systems that have
excellent export potential.
The car has all safety systems considered normal in modern cars, such as
latest seat-belt design and air bags. One of the navigation systems includes
a system that automatically contacts emergency services in the event of an
accident or breakdown. When reversing, a "park pilot" system provides
audible warning if an obstacle is dangerously close.
A unique safety system uses sensors in the seat and steering wheel that
measures body movement and grip. If the driver’s movements indicate
drowsiness, an alert alarm sounds and the driver has to re-set the control
which is built into the sun-visor.
The car’s body is made mostly from a light-gauge, high-strength BHP steel
known as "low-bake" steel. Many of the car’s components are made from
aluminium or magnesium for reduced mass, including a light-metal frame on
which the engine and generator are mounted for safety and ease of service.
