CCSE to Study Repurposing EV Batteries for Household Energy Use
In brief: The California Center for Sustainable Energy (CCSE) is leading a joint research study to explore extending the useful lifespan of electric vehicle (EV) batteries by repurposing them into household energy storage uses.
The joint study includes CCSE, San Diego Gas & Electric, AeroVironment, Flux Power, and the Transportation Sustainability Research Center at UC Berkeley.
The idea is to explore using plug-in electric and all-electric vehicle's batteries, once they've completed their life span in vehicles, as potential storage devices for home energy use. This could potentially reduce city smog levels and drains on the power grid as batteries storing electricity during off-peak hours could be used during peak hours to reduce emissions.
One of the down sides to batteries in electric vehicles is their relatively limited life span. Once they drop below 80% or so in efficiency levels, they become a liability to the vehicle's operation. Current models require that the batteries be replaced, usually every 5-7 years. The high cost of batteries currently makes this a large problem for EV makers.
The CCSE study hopes to alleviate some of those problems by increasing the value of the discarded battery packs, thus making them less costly to replace.
And so ...
