150 MPG Toyota Prius with aftermarket lithium-polymer battery pack
When PHEV battery is depleted, vehicle resumes normal operation using factory battery. And even when using PHEV, stock battery's power level are showed…The five kilovolt battery pack will charge up from completely empty in about six hours with 110 volt and 3 hours with 220 volt electricity. Installation of the kit takes about four hours and a few more hours of testing and configuration. Other than the extra batteries and an added charging outlet, the Prius remains unchanged. Kit integrates with vehicle without removing factory battery, and installation also includes reinforced impact resistant construction.
The Hymotion kits are currently being tested, but will be available to Prius owners by the end of first quarter of 2008. Price is not yet set, but will be approximately $9.500 dollars (including the installation) ~6.000€. This kit is a great addition to all wishing to have an electric car, that behaves like one as well. Green, economic, and quiet! All in all, we liked the quality, construction and integration/installation of Hymotion's Prius PHEV kit! With specified operating temperature range from -20C to 45C, and proper charging temperature range from -10C to 35C this will be a great buy for many owners! If it only proves to be imune to problems (like great impact on range when temperature is below zero).

We are surely looking forward to a heated up market with Co's like Toyota and ZAP.

When will the batteries be available
$$9,500 Still sounds kind of high on the battery pak. Better do lots of driving to offset costs. Prius already gets good milage as it is. Lets say you drive 12,000 miles per year @40mpg. the Prius would consume 300gal. of gas@ 4.00 per gallon this would cost 1200 per year in fuel. If batteries lasts longer than 8 years, or warrantied, then it would be a good deal
payback calculations cease to matter much when one has to wait in line for rationed fuel as we did during the 70's energy crisis. Now that we are staring peak oil in the face, the probability of future occurances of rationing or very high fuel prices get higher every day.
Don't forget that the benefit to everyones mother. Mother nature that is
I'm not exactly green. I'd rather it make financial sense in my pocket book with a major plus being less carbon and stench in the atmosphere. Plus you can stick it to a very unstable area of the world whose major economies run on "liquid gold, texas tea"

Get the price of $9500 cut in half and I will be knocking on the door to get it installed in my Prius.
