Southern California Edison Demonstrates Li Ion Battery with 180,000 Mile Lifespan
Battery provider Southern California Edison (SCE) has demonstrated a lithium ion battery with a lifespan of more than 180,000 miles, a major milestone in advanced battery performance that opens the door to a new generation of electric cars.
Since the average U.S. family car travels less than 15,000 miles each year, the battery could easily provide more than ten years service before it needs replacing. When you factor in the relatively low servicing costs of electric cars, this means that there is now a compelling case for such technology to power future plug-in vehicles.
The announcement follows a series of tests at the company’s Electric Vehicle Technical Center in Pomona, California. Over two and half years, SCE continuously ran a Johnson Controls-Saft battery subpack that is around one sixth of the size used in a plug-in hybrid electric vehicle. Based on the remarkable results, the U.S. Department of Energy have provided SCE with a full-sized battery pack and instructed the company to consider its viability for large scale application in passenger EVs.
Based on the results of this round of tests, it seems likely that one of the last remaining barriers to the wide-scale adoption of electric cars has been crossed, with room to spare.
