Abstract

An electrical energy system including an electric utility having an electricity generating apparatus and distribution lines, a plurality of electric vehicles and electric power storage apparatus receiving electrical power from the electric utility and supplying electrical power to the plurality of electric vehicles and to the electric utility when required.

Claims

1. An electrical energy system comprising:

an electric utility having an electricity generating apparatus and distribution lines;

a plurality of electric vehicles;

each electric vehicle including a metal/air battery operated by a liquid-like slurry;

means for removing spent slurry form said vehicle battery;

means for re-charging said spent slurry received from said removing means externally said a vehicle; and

electric power storage means receiving electrical power from the electric utility and being connected to said re-charging means so as to supply electrical power to the plurality of electric vehicles and to the electric utility when required.

2. A system according to claim 1 and wherein said electric power storage means is operative to receive electrical power from the electrical utility at low power demand times and to provide electrical to the electrical utility at high power demand times.

3. A system according o claim 1 and wherein said electric power storage means includes surge switching means for enabling the electric power storage means to absorb undesired power surges from the electrical utility as needed.

4. A system according o claim 1 and wherein said electric power storage means is operative to provide electrical power to the electrical utility at high power demand items.

5. A system according to claim 1 and wherein said electric power storage means is operative to provide electrical power to the electrical utility as needed to serve as a spinning reserve.

6. A system according to claim 1 and wherein said electric power storage means also comprises lead-acid batteries.

7. A system according to claim 6, wherein said lead-acid batteries are employed for relatively more frequent charging and discharging, while the metallic batteries which are operated by the liquid-like slurry employed for less frequent charging and discharging.

8. A system according to claim 1 wherein said means for removing spent slurry from vehicles is part of an electric vehicle recharging depot along with means for supplying said slurry to a storage facility to await recharging at low power demand times and means for supplying recharged slurry to vehicle from the electric power storage means.

9. An electrical energy system for use with an electric utility having an electricity generating apparatus and distribution lines, said system comprising:

a plurality of electric vehicles;

each electric vehicle including a metal-air battery operated by a liquid-like slurry;

means for removing spent slurry from said vehicle battery;

means for re-charging said spent slurry received from said removing means external of a said vehicle;

means for storing said spent slurry being connected to said recharging means; and

electric power storage means receiving electrical power from the electric utility and being connected to said re-charging means so as to supply electrical power to the plurality of electric vehicles and to the electric utility when required.

10. A system according to claim 9 wand wherein said electric power storage means is operative to receive electrical power from the electrical utility at low power demand times and to provide electrical power to the electrical utility at high power demand times.

12. A system according to claim 9 and wherein said electric power storage means is operative to provide electrical power to the electrical utility at high power demand times.

13. A system according to claim 9 and wherein said electric power storage means is operative to provide electrical power to other electrical utility as needed to serve as a spinning reserve.

16. A system according to claim 9 wherein said means for removing spent slurry from vehicles is part of an electric vehicle recharging debt along with means for supplying it to a storage facility to await recharging at low power demand times and means for supplying recharged slurry to vehicles form the electric power storage means.

11. A system according to claim 90 and wherein said electric power storage means includes surge switching means for enabling the electric power storage means to absorb undesired power surges from the electrical utility as needed.

14. A system according to claim 90 and wherein said electric power storage means also comprises lead-acid batteries.

15. A system according to claim 14 and wherein said lead-acid batteries are employed or relatively more frequent charging and discharging, while the metal/air batteries which are operated by the liquid-like slurry are employed for less frequent charging and discharging.

17. An electrical energy system comprising:

an electric utility having-an electricity generating apparatus and distribution lines;

a plurally of electric vehicles;

electric power storage means receiving electrical power from the electric utility and supplying electrical power to the plurality of electric vehicles nd to the electric utility when required; and

wherein said electric power storage means includes surge switching means for enabling the electric power storage mans to absorb undesired power surges from the electrical utility as needed.
