Believe it or not, EV battery life is still something of a Pandora's Box, even for automakers: they can tell you the battery pack's current and voltage, but not how it's really performing under pressure. Ford, GE and the University of Michigan are uniting to unlock that mystery through a new ARPA-E project. In its role, GE is developing a minuscule sensor array that will track the nuances of battery cells that existing technology misses; it will promptly hand the baton to researchers at the University of Michigan, who plan to both prove that GE's data is on the mark as well as develop tricks for predicting behavior. Ford handles the last mile, almost literally: it's planning to fit the GE sensor technology to one of its cars and test in a more realistic environment. Before you fantasize about knowing the lifespan of your Focus Electric's battery down to the minute, however, the new alliance is stressing that it's only just getting started -- there's another three years and $3.1 million to go before the project wraps up. If all goes according to plan, though, we'll have electric cars and plug-in hybrids that can not only tell when they've seen better days but can eke out extra miles through smarter battery designs.
