Electric car battery price could drop 65% by 2020

A report commissioned by the Committee on Climate Change (CCC) plotting the likely progress of battery technology and cost over the next couple of decades predicts a dramatic drop in price, adding to evidence that electric cars will soon become much more affordable.

The report’s most conservative estimate for a Nissan LEAF-sized pure-electric car would see the cost of a battery pack falling to just over half the current cost by 2020. The most optimistic scenario would see the cost falling to significantly less than half the current level.

The CCC’s interest in electric vehicles stems from its remit to advise the UK government on climate change issues and the setting of carbon reduction targets. It reckons that greenhouse gas emissions need to be reduced by at least 80% of 1990 levels by 2050. And it further believes that this can only be achieved by the ‘electrification of drivetrains’.

Looking even further out, the report’s authors reckon that by 2030, the average battery pack cost could fall to less than one third current levels, with range rising to 155 miles – a LEAF currently has a quoted range of just over 100 miles. Battery pack weight would also dramatically reduce by 2030 from a current average of 300kgs to just 180kgs.
