The two biggest Li-on battery manufacturers are predicting a halving of battery costs in the next 6-7 years when interviewed by the Wall Street Journal.

Although Brian Kesseler of Johnson Controls’ has taken the opportunity to point out that unless there is more standardization from the OEM vehicle manufacturers, the costs wont be as dramatic for the final vehicle costs, as the cells are just one part of the battery packs and the total vehicle costs.

Obviously something they are finding frustrating froim a manufacturing point of view, but none the less the cells are a big and expensive part, so if their forecasts are accurate then it bodes very well for the EV industry.

“We have an internal target to go down by at least a factor of two by 2020″…   …”I am very positive in terms of the slope that I see” – Prabhakar Patil, CEO, LG Chem Power

“Cell costs may indeed fall by half, but overall costs of battery packs, which include the control systems that surround the energy source, are unlikely to decline that quickly without standardization across auto makers” Brian Kesseler, President, Johnson Controls’ Power Solutions.
