2. The vehicle of claim 1 , wherein said data inputs include data relating to the relative cost of energy from consumable fuel and an expected cost of energy from said external power source at said predetermined future time.

3. The vehicle of claim 1 , further comprising:

a communication system to permit transmission of said input data from said external power source to said vehicle, while said vehicle is disconnected from said external power source.

4. The vehicle of claim 1 , wherein said data include predictive needs of said vehicle during a driving interval following said predetermined future time.

5. The vehicle of claim 1 , wherein said input data include current and predictive payment from said external power source for use of said battery when coupled to said external power source.

6. A system for optimizing a vehicle's energy consumption, comprising:

a computer coupled to a vehicle, the computer receiving data and instructions as inputs and providing outputs, wherein:

the vehicle has a battery-powered electric motor and a consumable fuel powered means, a battery powering said electric motor being rechargeable from an external power source and from said consumable fuel powered means, both of said receiving and providing occurring while said vehicle is disconnected from said external power source;

said data describing a condition of said external power source at a predetermined future time when said vehicle is expected to be coupled to said electric power source,

said instructions enabling said computer to determine an optimal state of electric charge of said battery at said predetermined future time, based on said condition, and

said outputs include signals controlling whether said battery is charged and/or discharged to reach said optimal state of electric charge at said predetermined future time.

7. The system of claim 6 , further comprising:

vehicle power system components controlled by said computer, wherein said computer controls said vehicle power system components to control recharging of said battery such that said battery is charged at said predetermined future time in a case when said condition of said electric power source is one where additional power producing capacity is needed.

8. The system of claim 6 , further comprising:

vehicle power system components controlled by said computer, wherein said computer controls said vehicle power system components to control recharging of said battery such that said battery is discharged at said predetermined future time in a case where said condition of said electric power source is one where additional power storage is needed.

9. The system of claim 6 , wherein said data include current and predictive needs of said electric power source.

10. The system of claim 6 , wherein said data include current and predictive cost of energy available from said electric power source.

11. The system of claim 6 , wherein said instructions are automated instructions.
