Title: 'Second-life' EV batteries could drive low-cost storage sector, says BNEF report

'Second-life' EV batteries could drive low-cost storage sector, says BNEF report (http://www.pv-magazine.com/news/details/beitrag/second-life-ev-batteries-could-drive-low-cost-storage-sector--says-bnef-report_100025911/#axzz4IH9g7sM8)

Nothing new(ish) but an interesting article, particularly this bit, which threw me:

Quote
Of that 29 GWh figure, around one-third (10 GWh) will get a second life as stationary storage. New storage systems can cost as much as $1,000/kWh, but even by 2018, the cost of repurposing a used EV battery could be as little as $49/kWh. Add in the $400/kWh cost to convert to stationary and the industry could be looking at masses of affordable batteries entering the market at a price point below $500/kWh.

Is that $400/kWh figure correct, and what does it mean? It seems particularly high when Tesla are aiming for $100/kWh for new batts.

Mart.
