New Life For Electric Car Batteries - Renewable Energy Storage
The mass uptake of electric cars looks to be finally about to occur; but what to
do with old batteries from the vehicles once they have reached the end of their
In electric car applications, batteries are usually determined to have ended
their serviceable life once they can no longer hold 80% of their original charge
once fully charged. Recycling the lithium batteries is possible, but poses
challenges and is quite energy intensive in itself.
With 80% charge still available and likely appreciable life left in the
batteries for less demanding applications, electric car companies are looking at
the second of the environmental 3 R's (Reduce, Re-use, Recycle) and considering
Chevrolet/General Motors in the USA has announced it is exploring the
possibility of re-using the batteries from its Chevrolet Volt electric
vehicle in applications such as storing electricity from wind and solar
as an alternative to traditional deep
General Motors and ABB Group are collaborating to also determine how the
Voltís 16-kWh lithium-ion batteries can be used to provide stationary electric
grid storage systems within smart grid infrastructure and backup power supplies
The Chevrolet Volt battery has an eight-year/100,000-mile warranty, the longest
in the industry says GM.
"Chevrolet and GM are committed to assuring that our vehicles minimize
their impact on the environment," says Micky Bly, GM Executive Director of
Electrical Systems, Hybrids, Electric Vehicles and Batteries. "Our focus on
finding additional applications for the Voltís batteries after their vehicle
use extends our commitment to unprecedented levels."
The Chevrolet Volt will be sold in Australia under the Holden brand in 2012.
