I don't want much more range than 40 miles. My lead Acid converison that will have a range of 45 miles is costing $3000 I wish they would sell the 40 mile range battery pack so I wouldn’t have to buy a $35,000 volt.

Where is the "big square" pack mentioned? mykallb

“Uhhhh the “big square” pack is not going to fit the Volt specifications as I understand them.”

Where is the “big square” pack mentioned?

This is based on the assertion that the new cell has an energy density about 20% higher than the round cell. (108 x 120 = 130) So the weight of the cells necessary for 16 KWH is about 130 Kg or 290 lbs. Naturally the battery cooling and managment equipment would add to the weight, but a battery pack of about 400 lbs seems feasible. The "T" battery storage compartment shown on the concept vehicle drawings runs from the back of the engine compartment to the rear where it "t's" near the real axle.

Nowhere in the original article are any size or weight figures given for the pack that is shown. This quote is from the original article: “Exact specifications of the cell have not been released.” And as I understand it, the final design of the actual vehicle is far from being at the “design freeze” stage. =========== Jim, Where do you get this information? On this very site Frank Weber stated just the opposite. He stated roughly that the Volt was near the design freeze stage. That's a far cry from your "understanding". Jim I Says:

Jim,

Where do you get this information? On this very site Frank Weber stated just the opposite. He stated roughly that the Volt was near the design freeze stage. That’s a far cry from your “understanding”.

And as I understand it, the final design of the actual vehicle is far from being at the "design freeze" stage. So how is it that you have come up with a weight of the full pack, and been able to determine that the size of the pack will not fit into the Volt? Unless you have access to information that does not seem to be available, or have actually held this new pack in your hands, I think your conclusions are a bit premature. IMHO, if the packs from A123 or LG did not come close to meeting the GM defined specs, I doubt seriously that they would be issuing press releases about the delivery of them to GM. mykallb #29:
