System and method for applying pulsation energy to online battery backup systems
First Claim
1. A method for applying pulsation energy to an online battery backup system including a battery string having an array of battery units, said method comprising the steps of:
- sampling at least one voltage sampling circuit to monitor a float voltage drop across terminals of battery units within said array of battery units;
selecting at least one battery unit, but not all of said battery units, from said array, said at least one battery unit having a float voltage drop greater than a float voltage drop of all remaining battery units sampled of said plurality of battery units; and
supplying pulsation energy to said selected at least one battery unit, but not said remaining battery units, sufficient to effect reconditioning to said selected at least one battery unit.

Abstract
A method of applying pulsation energy to an online battery backup system including the steps of (1) sampling at least one voltage sampling circuit to monitor a float voltage drop across the terminals of each battery unit within a plurality of battery units; (2) selecting from among the plurality of battery units the unit having the greatest float voltage drop; (3) operating a pulse generation circuit to apply pulsation energy across the terminals of only the selected battery unit; and (4) ceasing to operate the pulse generation circuit in response to a predetermined trigger. A generally corresponding method may be performed on each battery cell within the plurality of battery units. Also, battery pulsation systems for an online battery backup system including means for applying pulsation energy across the terminals of only a selected battery unit or a selected battery cell.

7. A battery pulsation system for an online battery backup system having a battery string composed of a plurality of connected battery units, with each unit including a pair of positive and negative terminals, the pulsation system comprising:
-
a plurality of switch devices, each of said switch devices being connected to a different one of said pair of positive and negative terminals of said plurality of battery units; a pulse generation circuit operatively connected to said plurality of switch devices; a voltage sampling circuit; and a controller operatively connected to said pulse generation circuit, said plurality of switch devices, and said voltage sampling circuit; wherein said plurality of switch devices is configured so that a circuit can be formed selectively by said controller between said pulse generation circuit and across any one of said pairs of terminals within said plurality of battery units and not remaining ones of said pairs of terminals; and said controller being programmed to sample said voltage sampling circuit to monitor a float voltage drop across said terminals of said battery units within said plurality of battery units;
select at least one of said battery units, but not all of said battery units, from said plurality of battery units, said at least one of said battery units having a float voltage drop greater than a float voltage drop of all remaining battery units sampled of said plurality of battery units; and
actuate said pulse generation circuit to supply pulsation energy to said selected at least one of said battery units, but not said remaining battery units, sufficient to effect reconditioning to said selected at least one battery unit. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A battery pulsation system for an online battery backup system having a battery string composed of a plurality of battery units, each of said battery units including a pair of positive and negative terminals, the pulsation system comprising:
-
at least one pulse generation circuit and at least one voltage sampling circuit, the circuits each being selectively connectable to one of the plurality of battery units across a first pair of said positive and negative terminals; and a controller operatively connected to said at least one pulse generation circuit and said at least one voltage sampling circuit; said controller being programmed to sample said at least one voltage sampling circuit, obtain float voltage drops across each of said pairs of positive and negative terminals in said plurality of battery units, select one of said battery units for pulsation, but exclude from said selection end ones of said battery units of said battery string, and operate said at least one pulse generation circuit to apply pulsation energy across said selected one of said first pair of positive and negative terminals of said selected one of said battery units. - View Dependent Claims (16, 17, 18, 19, 20, 21)
