Asked why not Nickel Metal Hydride batteries in the Volt, at least to start, he says "NiMH just doesn't do it." Interestingly, Lutz says GM is being approached by NiMH manufacturers to use this proven battery chemistry in the Volt. And if Lithium proves problematic, he says GM will again consider NiMH. But hold on.
The current state of market readiness of plug-in hybrid and electric vehicles presents serious challenges, particularly in mass production, given issues including range; cost; a charging time still longer than a conventional gasoline refueling; a broad variation in battery pack life, and the lack of infrastructure.
Traditionally, maximizing fuel economy and minimizing GHG emissions are the main objectives of the control development. The vehicle model was a pre-transmission parallel HEV model, with the hybrid propulsion system consisting of a gasoline engine coupled to an automatic transmission through a gear set and a clutch.

Hybrid systems other than the input power-split design pioneered by Toyota 17 years ago are still in early stages of development, and present huge opportunities to reduce cost through better designs, learning, and economies of scale. —“Hybrid Vehicles: Technology Development and Cost Reduction”.
The result is an 80+ mile-per-gallon vehicle — with even greater fuel economy possible utilizing bio-fuels. Such a vehicle could reduce gasoline consumption for the average American by 50 percent to 70 percent and reduce automobile emissions well in excess of emissions that might result from the additional use of power plants.
Toyota’s goal was to reduce the cost, weight and volume of the pack from the NiMH system used earlier. A key goal for development of the Prius Plug-in was to deliver the optimal balance of performance, range, economy, packaging and affordable price. Changes include: Completely new battery design.

We want to help the (automotive) customer optimize the solution,we can work in the mode where we are providing the black box, we go one step further and we look at [the consumer] and their requirements whether it’s acceleration, fuel economy, etc. In general, the price of gasoline needs to be above US$3.50/gallon Earlier post.).
Scientist have confirmed that unlike gasoline cars, plug-ins will get cleaner as they get older -- because our power grid is getting cleaner. The comparison keeps being raised, though studies are conclusive: The "well-to-wheel" emissions of electric vehicles are lower than those from gasoline internal combustion vehicles.
Company says its focusing on gasoline and hydrogen. 2010 Prius designed to be manufactured with NiMH or Lithium batteries. USA Today ) 10/25/06 DaimlerChrysler is downright reluctant, even though it has built four test models, commercial-size vans that run on gasoline and electricity. No announced plans. Red Herring ).
Even so, most next gen EV manufacturers are focused on lithium ion (and to a lesser extent NiMH) as the core technology to power their cars. More often than not, the “recycling&# of NiMH or lithium-ion batteries involves shipping them off to places like China, where their fate is truly unknown.
BYD has also begun selling a plug-in electric car with a backup gasoline engine, a move putting it ahead of GM, Nissan, and Toyota. They generate fewer greenhouse gas emissions than cars that burn gasoline, and they have lower fuel costs, even when oil is cheap. tons of carbon dioxide. Business of Green B.T.W.
