It is understood that the average price of lithium-ion battery packs for electric vehicles in the first quarter of 2012 was US$689/kWh, a decrease of 14% from the price of approximately US$800/kWh in the same period of last year, compared to the price level of more than US$1,000 in 2009. About 30% lower.
The main reason for this phenomenon is that the investment on the supply side is strong and the consumer demand for electric vehicles has not been improved. The capacity of the electric vehicle battery pack exceeds the demand.
The battery is one of the most important factors that affect the cost of electric vehicles and the development of the electric vehicle industry. The sharp decline in prices is not good news for battery manufacturers, but it is very important for the long-term healthy development of the industry.
