Everything we know about hybrids and plug-ins today is wrong
One major barrier to electrification overcome? Toyota will lose its hybrid crown, and lithium-ion might be just fine for the battery revolution In general, most believe that in order to truly replace gasoline cars, battery packs will eventually have to move beyond lithium-ion technologies, into lithium-air and numerous other technological possibilities, for example. According to Envia Systems, however, their new cathode materials could put electric cars on par with conventional gas guzzlers now. And on a different electrified note, a new study suggests that Toyota’s days as the hybrid king could be numbered. According to the International Council on Clean Transportation (ICCT) by around 2020 the manufacturing costs of hybrid vehicles will decline to about $1200 more than similarly sized conventional vehicles, leading to 70 percent hybrid penetration by 2030. However, it won’t be planetary geared, powersplit hybrids such as Toyota’s that will dominate this new hybrid future. Instead, P2 hybrids — single motor and 2 clutches used between engine and transmission — will ultimately enable the 70 percent marketshare. Of course, maybe hybrid cars won’t be needed if Envia’s battery claims prove conclusive — although with up to 60 percent of Americans without off-street parking, hybrids will probably still be needed for a long time. Still, Envia could shake up this hybrid forecast. With 400 kWh versus a little more than a 100 today and costs as low as $125 per kWh versus between $300 – $500 today, Envia’s batteries offer some pretty serious potential. Even if this breakthrough results in just twice the range as today, at half the cost, that would still be a significant breakthrough. A best case scenario, on the other hand, could be a real game changer. Thus far Envia’s battery packs appear to need further cycling tests to demonstrate that they have the longevity needed to live up to this claim. Likewise, charging times are still in issue, but if all proceeds smoothly, Envia believes mass production could begin as early as 2015. Any way or another, this is a story that should only get more interesting. Sources: Envia , MotorTrend , & GreenCarCongress
