Asymmetric battery pulsation system

1. A battery pulsation system comprising:

a battery string including a plurality of cells, said battery string defining a positive end and a negative end;

a first source of pulsation energy connected to a first cell of said plurality of cells to supply a first pulsation energy thereto, said first cell includes a first positive terminal and a first negative terminal and is generally adjacent to said positive end of said battery string, wherein said first source of pulsation energy applies a greater portion of said first pulsation energy to said first negative terminal than said first positive terminal; and

a second source of pulsation energy connected to a second cell of said plurality of cells to supply a second pulsation energy thereto, said second cell includes a second positive terminal and a second negative terminal and is generally adjacent to said negative end of said battery string, wherein said second source of pulsation energy applies a greater portion of said second pulsation energy to said second positive terminal than said second negative terminal.

2. The system of claim 1 further comprising a load connected to said battery string.

3. The system of claim 1 wherein said plurality of cells are lead-acid battery cells.

4. The system of claim 1 further comprising a primary power supply, said primary power supply being connected to said battery string to supply charging energy thereto.

5. The system of claim 4 wherein said primary power supply and said battery string are connected to a load.

6. The system of claim 1 wherein said first cell is a positive end cell of said battery string.

7. The system of claim 1 wherein said second cell is a negative end cell of said battery string.

8. The system of claim 1 wherein said first cell is at least one cell removed from a positive end cell of said battery string.

9. The system of claim 1 wherein said second cell is at least one cell removed from a negative end cell of said battery string.

10. The system of claim 1 wherein said first source of pulsation energy applies at least about 60 percent of said first pulsation energy to said first negative terminal and said second source of pulsation energy applies at least about 60 percent of said second pulsation energy to said second positive terminal.

11. The system of claim 1 wherein said first source of pulsation energy applies at least about 80 percent of said first pulsation energy to said first negative terminal and said second source of pulsation energy applies at least about 80 percent of said second pulsation energy to said second positive terminal.

12. The system of claim 1 wherein said first source of pulsation energy applies about 100 percent of said first pulsation energy to said first negative terminal and said second source of pulsation energy applies about 100 percent of said second pulsation energy to said second positive terminal.

13. The system of claim 1 wherein said first source of pulsation energy operates independently of said second source of pulsation energy.

14. The system of claim 1 wherein said first source of pulsation energy is synchronized with said second source of pulsation energy.

15. The system of claim 1 wherein said first source of pulsation energy is configured to supply said first pulsation energy at the same time that said second source of pulsation energy supplies said second pulsation energy.

16. The system of claim 1 wherein said first source of pulsation energy is a first pulsation device and said second source of pulsation energy is a second pulsation device.

17. The system of claim 1 wherein said first source of pulsation energy and said second source of pulsation energy are part of a single pulsation device.

18. A battery pulsation system comprising:

a battery string including a plurality of cells, said plurality of cells including a positive end cell and a negative end cell;

a first pulsation device connected to said positive end cell to supply a first pulsation energy thereto, said positive end cell includes a first positive terminal and a first negative terminal, wherein said first pulsation device applies at least about 60 percent of said first pulsation energy to said first negative terminal; and

a second pulsation device connected to said negative end cell to supply a second pulsation energy thereto, said negative end cell includes a second positive terminal and a second negative terminal, wherein said second pulsation device applies at least about 60 percent of said second pulsation energy to said second positive terminal.

19. The system of claim 18 wherein said first pulsation device applies about 100 percent of said first pulsation energy to said first negative terminal and said second pulsation device applies about 100 percent of said second pulsation energy to said second positive terminal.

20. The system of claim 18 wherein said first pulsation device is synchronized with said second pulsation device.

21. A battery pulsation system comprising:

a battery string including a plurality of cells, said plurality of cells including a positive end cell and a negative end cell;

a first pulsation device connected to a first cell of said plurality of cells to supply a first pulsation energy thereto, said first cell being at least one cell removed from said positive end cell, said first cell includes a first positive terminal and a first negative, wherein said first pulsation device applies at least about 60 percent of said first pulsation energy to said first negative terminal; and

a second pulsation device connected to a second cell of said plurality of cells to supply a second pulsation energy thereto, said second cell being at least one cell removed from said negative end cell, said second cell includes a second positive terminal and a second negative terminal, wherein said second pulsation device applies at least about 60 percent of said second pulsation energy to said second positive terminal.

22. The system of claim 21 wherein said first pulsation device is synchronized with said second pulsation device.
