Abstract

An automatic battery control system for vehicles and the like, having a main battery used for motor starting and one or more auxiliary batteries, and wherein each of such batteries is connected to a diode or rectifier, and wherein the two or more diodes or rectifiers are connected to a common terminal which is connected to a generator, whereby the main and auxiliary batteries may be discharged independently of each other at their respective loads, and may be charged automatically from the common generator source, with the diodes or rectifiers preventing the batteries from discharging back through the common terminal.

Claims

1. An automatic battery control system for vehicles and the like, comprising:

a. a first electrical circuit having a first battery therein;

b. a second electrical circuit having a second battery therein;

c. a generator;

d. a first rectifier connected in said first electrical circuit for permitting flow of electrical current in only the one direction from said generator to said first battery and for blocking current flow in the opposite direction;

e. a second rectifier connected in said second electrical circuit for permitting flow of electrical current in only the one direction from said generator to said second battery and for blocking current flow in the opposite direction;

f. a common terminal connected to both said first rectifier and said second rectifier and to said generator for charging both of said batteries from the common generator as needed;

g. said first circuit having a terminal connected to said first rectifier at the side of the first rectifier opposite from said common terminal and to which said first battery is connected;

h. means in said first electrical circuit for connecting a first electrical load to said first battery for discharging same independently of said second battery;

i. said second circuit having a terminal connected to said second rectifier at the side of the second rectifier opposite from said common terminal and to which said second battery is connected;

j. means in said second electrical circuit for connecting a second electrical load to said second battery for discharging same independently of said first battery;

k. switch means including a relay connected to said first electrical circuit through a first switch rectifier and connected to said second electrical circuit through a second switch rectifier so that power may be drawn from either or both of said electrical circuits to operate the relay;

l. an additional electrical circuit connecting said first and second electrical circuits in parallel through said relay when in the closed position; and

m. said first and second switch rectifiers preventing said first battery and said second battery from discharging from one to the other.

2. An automatic battery control system for vehicles and the like, comprising:

a. a first electrical circuit having a first battery therein;

b. a second electrical circuit having a second battery therein;

c. a generator;

d. a first rectifier connected in said first electrical circuit for permitting flow of electrical current in only the one direction from said generator to said first battery and for blocking current flow in the opposite direction;

e. a second rectifier connected in said second electrical circuit for permitting flow of electrical current in only the one direction from said generator to said second battery and for blocking current flow in the opposite direction;

f. a common terminal connected to both saId first rectifier and said second rectifier and to said generator for charging both of said batteries from the common generator as needed;

g. said first circuit having a terminal connected to said first rectifier at the side of the first rectifier opposite from said common terminal and to which said first battery is connected;

h. means in said first electrical circuit for connecting a first electrical load to said first battery for discharging same independently of said second battery;

i. said second circuit having a terminal connected to said second rectifier at the side of the second rectifier opposite from said common terminal and to which said second battery is connected;

j. means in said second electrical circuit for connecting a second electrical load to said second battery for discharging same in dependently of said first battery;

k. said generator being connected to said common terminal for charging each of said batteries and furnishing current for each of said electrical loads through its respective rectifier;

l. a third electrical circuit connected to said first electrical circuit and having a third battery therein;

m. means for selectively connecting said first and second electrical circuit and generator in series for charging a third battery; and

n. means for isolating the third electrical circuit to prevent the third battery from discharging into said first and second electrical circuits and generator circuit.
