Abstract

A pseudo double circuit battery and associated circuit for incorporating the battery into conventional vehicle starting and charging systems. The battery is made up of a series of conventional cells and includes at least one cell which has an additional positive or negative terminal to form an auxiliary circuit terminal. During a starting or cranking phase of operation, the main circuit of the battery is isolated from the auxiliary circuit and is connected to energize the heavy load circuits of the automobile. The auxiliary terminal is connected so as to provide stable power to light load circuits, for example the ignition circuit. During running of the automobile the main and auxiliary terminals are connected.

Claims

1. A battery comprising:

a casing;

a plurality of conventional battery cells placed within said casing, each of said cells including positive and negative plates and associated positive and negative terminals for said respective positive and negative plates, said plates of said cells being electrically connected in series between their respective positive and negative terminals, and including a main positive terminal and main negative terminal electrically connected from said series connection of said cells; and

,

at least one of said plurality of said cells forming a modified cell and including an additional auxiliary terminal connected to a separated plate within said cell.

2. A battery as in claim 1, wherein:

said modified cell is a last one of said series connection of cells in said battery.

3. A battery as in claim 1, wherein:

said separated plate comprises a separated one of said plates included within the number of plates n existing in said conventional cells of said battery so that said modified cell includes a separated plate and n-1 other plates comprising the remainder of said plates within said modified cell.

4. A battery as in claim 1, wherein:

said separated plate comprises an additional plate included within said modified cell, so that the number of plates in a conventional cell of said battery is n and the number of plates in said modified cell includes said separated plate and n other plates comprising the remainder of said plates in said modified cell.

5. A battery as in claim 1, wherein:

said separated plate comprises a positive plate.

6. A battery as in claim 1, wherein:

said separated plate comprises a negative plate.

7. A battery as in claim 1, wherein:

said number of cells within said battery is more than 2.

15. A battery as in claim 1, further comprising:

an acid bath in each of said cells; and

,

baffle means included in said modified cell for inhibiting mixing of said acid bath in said modified cell, said baffle being positioned between said a volume of said modified cell including said separated plate and one of another of said plates within said modified cell and a remaining volume of said modified cell.

8. A circuit and battery for supplying a main and auxiliary potential to separate load demands, comprising:

a battery having a casing and a plurality of conventional battery cells placed within said casing, each of said cells including positive and negative plates and associated positive and negative terminals for said plates, said plates of said cells being electrically connected in series between their respective positive and negative terminals, and including a main positive terminal and a main negative terminal electrically connected from said series connection of said cells, and at least one of said plurality of cells forming a modified cell and including an additional auxiliary terminal connected to a separated plate within said cell; and

,

a switch means, connected to one of said main positive or negative terminals and connected to said auxiliary terminal, for selectively combining or separating the electrical potential of said terminals connected to said switch and supplying the combined electrical potential to a load in a first position of said switch, and supplying the respective separate potentials of said main and auxiliary terminals to main and auxiliary loads in a second position of said switch.

9. A circuit and battery as in claim 8, wherein:

said modified cell is a last one of said series connection of cells in said battery.
