EV Battery Second Life

Why Used Electric Car Batteries Could Be Crucial To A Clean Energy Future

Joe Romm, May 9, 2016 (ClimateProgress)

“Battery costs are plummeting to levels that make EVs a truly disruptive technology…[and] electric vehicle (EV) sales are exploding world-wide…[Major EV makers] are now exploring how much value their EV battery has for use in the electricity storage market after that battery can no longer meet the strict requirements for powering its car. This potential second life for EV batteries is a clean energy game changer for two reasons…[U]sed EV batteries hold the promise of much cheaper electricity storage for renewables than is available today…[and that would allowEV makers to charge less for their cars and enable] deep and rapid penetration of renewables in the 2020s…[W]ith hundreds of thousands of EVs already sold in the U.S., at least one company that purchases used EV batteries has indicated the price is an astounding $100 per kiloWatt-hour, far cheaper than anything on the market today…[Where second-life battery prices end up depends on how fast the electric vehicle market scales up and how quickly prices for new batteries drop but when] the trickle turns into a flood, the business of electricity storage and demand response — both of which enable far deeper penetration of renewable power — will never be the same.” click here for more
