Lithium-ion battery pack prices, which were above $1,100 per kilowatt-hour in 2010, have fallen 89% in real terms to $137/kWh in 2020. By 2023, average prices will be close to $100/kWh, according to the latest forecast from research company BloombergNEF (BNEF).
For the first time, battery pack prices of less than $100/kWh have been reported. These were for batteries in e-buses in China. While these were the lowest reported price, the volume-weighted average price for e-buses in China was slightly higher, $105/kWh.
Battery electric vehicle (BEV) pack prices are $126/kWh on a volume-weighted average basis. At the cell level, average BEV prices were just $100/kWh. This indicates that on average, the battery pack portion of the total price accounts for 21%.
