• eMotorWerks JuiceBox wall mount charging Tesla Model X

    At first glance, a new business agreement between home charger manufacturer eMotorWerks and utility software provider LO3 Energy sounds strictly like the stuff of dull business contract lawyers. Dig a little deeper, though, and it could be the kernel of the next generation electrical system, long discussed, but never-quite-practical vehicle-to-grid infrastructure. As many electric-car drivers know, eMotorWerks builds networked JuiceBox home chargers, some faster than most others, that allow users to program them via the internet to start and stop charging as energy rates fluctuate. The boxes...

    One of the earliest electric-car prototype test fleets of the modern day was made up of several hundred MINI E two-seaters, which hit U.S. roads on two-year leases from 2008 through 2010. MINI E drivers who loved driving electric--which is to say, many of them--were offered replacement BMW ActiveE...

  • 2012 Mitsubishi i

    Vehicle-to-grid (V2G) isn’t a new concept, and is the name given to technology which gives plug-in vehicles the ability to feed power stored in their battery packs back to the utility company at points of peak electrical demand. But we’ve yet to see the technology being implemented in mainstream electric cars - at least, not yet. Now Japanese automaker Mitsubishi has announced that it plans to offer a device that will enable owners of its ‘i’ electric car to power domestic appliances or light a whole house from its 16 kilowatt-hour battery pack in the event of a power...
