The cost of electric vehicle battery packs is falling
so rapidly they are probably already cheaper than expected for
2020, according to a new study in Nature Climate Change.
Electric vehicles remain more expensive than
combustion-engine equivalents, largely because of battery costs. In
2013 the International Energy Agency (IEA) estimated cost-parity
could be reached in 2020, with battery costs reaching $300 per
kilowatt hour of capacity.
But market-leading firms were probably already
producing cheaper batteries last year, says today's new research.
It says its figures are "two to four times lower than many recent
peer-reviewed papers have suggested".
