Rapidly falling costs of battery packs for electric vehicles

In order to properly assess the prospects of a commercially competitive battery electric vehicle (BEV), one must have accurate information on the current and predicted cost of the battery pack.
The literature shows that costs are falling, but there is a lot of uncertainty about the past, present and future costs that dominate Li-
Ion Technology 1, 2, 3.
This paper presents an original systematic review that analyzes more than 80 different estimates and Reports 2007-2014 to systematically track Li-
Ion battery pack from BEV manufacturer.
We showed the industry.
From 2007 to 14%, extensive cost estimates fell by about 2014 per year, from over $1,000 per kilowatt hour to around $410 per kilowatt hour, and the cost of battery packs used in the market-
Leading BEV manufacturers are even lower, $300 per kilowatt hour, down 8% per year.
Learning rate, cost reduction after cumulative doubling of production, consistent with earlier research on vehicle battery technology, found between 6 and 9%.
We revealed that Lee-
Ion battery packs continue to decline, and the cost of market leaders is much lower than previously reported.
This has a significant impact on the assumptions used to model future energy and transport systems and allows for low
Carbon transport.
