rich, all I know is the Toshiba battery can take a charge in 5-minutes at an extremely high rate of transfer due to the new nanotube technology used to design the lithium ion battery.
From what I've read, it can go about 135-miles on a single charge, and that's typical driving. Performance will be whatever the builder of the car wants to make it.
The technology to make a hybrid car (gasoline/battery) is already over a decade old, so this is not rocket science. It's a big leap in battery technology that enables the gasoline/electric battery hybrid car to run pretty much exclusively on battery.
As far as the amperage needed, I'm not sure. It runs on regular 110-volt household current, so it can't be too much. It should be a similar draw to running a high power hair dryer.
