Putting old hybrid car batteries to good use

When people talk about how long the batteries in hybrid and electric vehicles last, keep in mind that the battery is still usable at the end of its ‘life’, it just has decreased capacity (around 80% of its original capacity seems to be a common number there).  It’d be a shame to recycle a battery with so much energy storage potential…which is why it’s nice to see things like this system from GM, designed to use the cast-aside batteries from their Volts (once they get to that age, that is…it’s still a very new car).  One of the systems shown here provides enough energy storage to power three to five average homes, so a more likely use would be in an off-grid system in a larger building, for example.  It’s an imperfect solution, but this is an emerging market and it’s nice to see that hybrid batteries have a good chance of finding life beyond the pavement.
