Abstract
A vehicle having an electric hybrid power system is provided. A battery pack stores electricity to power the electric motor. The battery pack includes a first plurality of batteries connected in parallel with a second plurality of batteries. The first plurality of batteries are Nickel Metal Hydride (NiMH), and the second plurality of batteries provide high power output at lower temperatures. In addition, the second plurality of batteries may also have a low energy density.
