UltraBattery sets new standard for HEVs
The odometer of a low emission hybrid electric test vehicle today
reached 100,000 miles as the car circled a track in the UK using the
power of an advanced CSIRO battery system.
The UltraBattery combines a supercapacitor and a lead acid battery in a
single unit, creating a hybrid car battery that lasts longer, costs less
and is more powerful than current technologies used in hybrid electric
"The UltraBattery is a leap forward for low emission transport and
uptake of HEVs," said David Lamb, who leads low emissions transport
research with the Energy Transformed National Research Flagship.
"Previous tests show the UltraBattery has a life cycle that is at least
four times longer and produces 50 per cent more power than conventional
battery systems. It's also about 70 per cent cheaper than the batteries
currently used in HEVs," he said.
By marrying a conventional fuel-powered engine with a battery to drive
an electric motor, HEVs achieve the dual environmental benefit of
reducing both greenhouse gas emissions and fossil fuel consumption.
The UltraBattery also has the ability to provide and absorb charge
rapidly during vehicle acceleration and braking, making it particularly
suitable for HEVs, which rely on the electric motor to meet peak power
needs during acceleration and can recapture energy normally wasted
through braking to recharge the battery.
Over the past 12 months, a team of drivers has put the UltraBattery to
the test at the Millbrook Proving Ground in the United Kingdom, one of
Europe's leading locations for the development and demonstration of land
"Passing the 100,000 miles mark is strong evidence of the UltraBattery's
capabilities," Mr Lamb said.
"CSIRO's ongoing research will further improve the technology's
capabilities, making it lighter, more efficient and capable of setting
new performance standards for HEVs."
The UltraBattery test program for HEV applications is the result of an
international collaboration. The battery system was developed by CSIRO
in Australia, built by the Furukawa Battery Company of Japan and tested
in the United Kingdom through the American-based Advanced Lead-Acid
UltraBattery technology also has applications for renewable energy
storage from wind and solar. CSIRO is part of a technology start-up that
will develop and commercialise battery-based storage solutions for these

CSIRO initiated the National Research Flagships to provide science-based
solutions in response to Australia's major research challenges and
opportunities. The nine Flagships form multidisciplinary teams with
industry and the research community to deliver impact and benefits for
