Plug In America |

Are the batteries ready?

Yes. According to an Electric Power Research Institute report, battery durability testing sponsored jointly by EPRI and Southern California Edison demonstrate that current lithium-ion batteries are likely to retain sufficient capacity for more than 3,000 dynamic deep-discharge cycles (about 10-12 years of typical driving.) Major automakers are offering 8-year, 100,000-mile warranties on the batteries of today's plug-in vehicles. Put lots of batteries in a car -- as in the Tesla Roadster -- and you can drive 250 miles on a charge. As with any new technology, the cost of EV batteries will become even more affordable once they're in mass production. Research continues to explore multiple newer battery chemistries that promise an exciting future for plug-in vehicles.
