Abstract

A battery charging and pulsating system including a battery having a positive terminal and a negative terminal, a charger electrically connected to the positive and the negative terminals of the battery, the charger including a controller, a pulsator electrically connected to the positive and the negative terminals of the battery, the pulsator including a controller, and a voltage measuring circuit electrically connected to the positive and the negative terminals of the battery, the voltage measuring circuit being adapted to measure a voltage across the positive and the negative terminals of the battery, wherein the controller of the pulsator is adapted to activate the pulsator when the measured voltage is at least one of (1) at or below a predetermined threshold voltage and (2) at or above a predetermined gassing voltage.

Claims

1. A battery charging and pulsating system comprising:

a battery having a positive terminal and a negative terminal;

a charger electrically connected to said positive and said negative terminals of said battery, said charger including a controller;

a pulsator electrically connected to said positive and said negative terminals of said battery, said pulsator including a controller; and

a voltage measuring circuit electrically connected to said positive and said negative terminals of said battery, said voltage measuring circuit being adapted to measure a voltage across said positive and said negative terminals of said battery,

wherein said controller of said pulsator is adapted to activate said pulsator when said measured voltage is at least one of (1) at or below a predetermined threshold voltage and (2) at or above a predetermined gassing voltage.

2. The system of claim 1 wherein said battery is a lead-acid battery.

3. The system of claim 1 wherein said voltage measuring circuit is associated with said controller of said pulsator.

4. The system of claim 1 wherein said controller of said charger and said controller of said pulsator are one and the same.

5. The system of claim 1 wherein said charger and said pulsator as associated with a single charging and pulsating device.

6. The system of claim 1 wherein said predetermined threshold voltage is a voltage indicative of no charging current being supplied to said battery by said charger.

7. The system of claim 1 wherein said predetermined gassing voltage is a voltage corresponding to about 80 percent of a fully charged voltage of said battery.

8. The system of claim 1 further comprising a schedule of operation for operating said pulsator, wherein said pulsator is activated according to said schedule of operation.

9. The system of claim 8 wherein said schedule of operation is a varied schedule of operation having at least a first portion and a second portion, said second portion occurring at a time after said first portion, wherein said pulsator is operated less frequently during said first portion than during said second portion.

10. The system of claim 1 wherein said pulsator is adapted to supply a pulse to said battery, said pulse having a pulse strength, and wherein said controller of said pulsator is adapted to control said pulse strength.

11. The system of claim 1 wherein said controller of said pulsator is adapted to activate said pulsator after a delay period.

12. The system of claim 1 wherein said charger is deactivated when said controller of said charger determines that said battery is disconnected from said charger.
