EPRI / DeJong Learning Curve Projection for Li Ion Battery
GM and EPRI have a major collaborative effort going http://gm-volt.com/2008/07/21/gm-launches-major-collaboration-with-epri-and-30-utility-companies-to-ready-the-grid-for-the-volt/, so these numbers have some credibility.
Attached is a spreadsheet of comparative maintenance costs. Tire and brake wear of E-REV is different from ICE.
The Electric Power Research Institute (http://my.epri.com/portal/server.pt?) did a recent analysis on the projected cost of Li ion batteries. Using this data and the DeJong learning curve gives the learning curve below. We note that the curve flattens out at volumes of 100,000 and greater, which corresponds to the Volt's third year production and beyond volumes. The Volt (16KWHr) battery cost for the third year and beyond is projected to level out at about $5000.
