A new system of battery for hybrid electric cars
An electric car equipped with a new type of battery called UltraBattery developed by the CSIRO has traveled the distance record of 161,000 km.
The UltraBattery combines a super-capacitor and a conventional lead-acid battery in a single module. This system would last longer, be cheaper and more powerful than the technologies currently used to power electric hybrid vehicles. Tests have shown that UltraBattery lasts at least four times longer, is one and a half times more powerful and would be about 70% cheaper than other batteries.
The system is capable of delivering and absorbs large current densities rapidly during acceleration and braking. The pull of the vehicle is provided by lead-acid battery and accelerated benefits from the input power of the super-capacitor. The energy that is usually lost in braking the vehicle is returned to recharge the super-capacitor.
It is more powerful than current technologies used in hybrid electric vehicles (HEVs). “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.
The Ultrabattery, manufactured in Japan by the company Furukawa Battery Company, was tested during the last 12 months on the trail of test centre car Millbrook in the UK.
Along with research activities in the field of hybrid electric vehicles, the CSIRO is currently developing new energy storage systems for electrical installations using solar and wind power.
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 commercialize battery-based storage solutions for these energy sources
