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.
Claims20
A power supply for a vehicle, comprising:
- a) a plurality of first batteries;
- b) a plurality of second batteries being connected in parallel with said plurality of first batteries, said plurality of first batteries and said plurality of second batteries being configured to provide and receive a source of power from an electric machine.
A power supply for a hybrid vehicle, comprising:
- a) an electrical storage medium having a first plurality of batteries being connected in parallel with a second plurality of batteries, said electrical storage medium providing power for an electric motor drivably connected to at least one ground-engaging drive wheel of said vehicle, said electric motor selectively having a function of rotating said drive wheel, said electrical storage medium selectively powering said electric motor;
- b) a liquid-fueled engine drivably connected to at least one ground-engaging wheel, said liquid fueled engine selectively having a function of rotating said drive wheel;
- and
- c) a generator coupled for selectively recharging said electrical storage medium.
A method for providing and storing power and a hybrid vehicle, comprising:
- connecting a first set of batteries to a second set of batteries, said first set of batteries having a similar open circuit voltage as said second set of batteries, said first set of batteries being connected in parallel with said second set of batteries;
- drawing power from either said first set of batteries or said second set of batteries;
- and
- storing power in either said first set of batteries or said second set of batteries.
A power supply for a vehicle, comprising:
- a) a plurality of first batteries;
- b) a plurality of second batteries being connected in parallel with said plurality of first batteries to form an electric storage medium, said plurality of first batteries and said plurality of second batteries being configured to provide and receive a source of power from an electric machine, said electric machine providing either a driving force or a stopping force to at least one ground engaging drive wheel of said vehicle.
