The electric vehicle pioneer behind the Fisker Automotive Karma plug-in hybrid (PHEV), Henrik Fisker, is continuing to tease the upcoming unveiling of a new prototype, which is expected to be ready for show sometime this summer.
Importantly, it was also reiterated that the EMotion EV will possess a range of at least 400 miles per full charge. That means that the model (err, prototype) will possess the most substantial range out there amongst EVs — if it’s released anytime soon, that is. (Other companies could of course create prototypes that possess a range over 400 miles, but Fisker does claim that the production EMotion will possess such a range as well.)
The EMotion “will employ graphene-based ultracapacitors,” Steve Hanley at Gas2 reports. “The technology breakthrough comes courtesy of Nanotech Energy, a UCLA research group that specializes in perfecting graphene energy storage devices.”
“Graphene shows a higher electron mobility, meaning that electrons can move faster through it. This will charge a battery much faster,” says Lucia Gauchia, an assistant professor of mechanical engineering and energy storage systems at Michigan Technological University. “Graphene is also lighter and it can present a higher active surface, so that more charge can be stored.”
