System And Method For Assessing A Capacity Of A Backup Battery And Power Plant Incorporating The Same

View page
US Patent:
63044714, Oct 16, 2001
Filed:
Jun 3, 1999
Appl. No.:
9/324753
Inventors:
Subhas Chandra Chalasani - Plano TX
Vijayan Joseph Thottuvelil - Plano TX
International Classification:
H02M 542
H02J 700
G01N 27416
US Classification:
363 84
Abstract:
For use with a power plant having a rectifier and a backup battery coupled to a variable load, a system for, and method of, assessing a capacity of the backup battery. In one embodiment, the system includes: (1) a controller, coupled to the rectifier, that controls an output current of the rectifier to maintain a discharge current of the backup battery at a substantially constant level and (2) a voltage sensor, coupled to the backup battery, that measures a voltage of the backup battery.

Mode Selection Circuit For A Battery And Method Of Operation Thereof

View page
US Patent:
6037747, Mar 14, 2000
Filed:
Oct 15, 1997
Appl. No.:
8/950642
Inventors:
Subhas Chandra Chalasani - Plano TX
Mark Elliot Jacobs - Dallas TX
Vijayan Joseph Thottuvelil - Plano TX
Assignee:
Lucent Technologies Inc. - Murray Hill NJ
International Classification:
H01M 1044
H01M 1046
US Classification:
320125
Abstract:
For use with a reserve battery couplable to a charging circuit capable of providing a charging current to the reserve battery, a mode selection circuit and a method of operation thereof. The mode selection circuit includes, in one embodiment, (1) a signal generator that generates a signal based on a temperature of the reserve battery and (2) a mode-changing circuit, coupled to the signal generator, that accepts the signal and selects an alternative one of: (a) a non-charge mode in which the charging current is substantially interrupted when the temperature is greater than a reference temperature and (b) a charge mode in which the charging current is provided to the reserve battery when the temperature is less than the reference temperature.

Recharging Circuit And Method For Recharging A Battery Having A Reference Electrode

View page
US Patent:
61372668, Oct 24, 2000
Filed:
Jun 2, 1999
Appl. No.:
9/324815
Inventors:
Subhas Chandra Chalasani - Plano TX
Vijayan Joseph Thottuvelil - Plano TX
Assignee:
Lucent Technologies, Inc. - Murray Hill NJ
International Classification:
H02J 700
H02J 704
US Classification:
320133
Abstract:
A battery recharging circuit for a valve regulated lead-acid battery having a plurality of cells, each cell including a positive electrode, a negative electrode, a DC voltage source for generating a voltage applied to the positive and negative battery electrodes, and a reference electrode includes a regenerating voltage source for selectively applying a regenerating voltage between the reference electrode and one of the battery electrodes for regenerating the reference electrode, and a reference voltage source for generating a reference voltage. The circuit further includes circuitry for measuring the voltage level between the reference electrode and a battery electrode after removal of the regenerating voltage from the reference electrode. Circuitry compares the measured voltage level to the reference voltage to generate an error correction signal. The voltage generated by the DC voltage source is adjusted based upon the error correction signal, such that the voltage of the DC voltage source applied to the battery electrodes adjusts the voltage level between the reference electrode and one of the battery electrodes to be substantially equal to the reference voltage.

Battery Container

View page
US Patent:
61874744, Feb 13, 2001
Filed:
Feb 3, 1999
Appl. No.:
9/244555
Inventors:
Subhas C. Chalasani - Plano TX
Mathew Joseph - Mesquite TX
Roy Kuipers - Rockwall TX
Assignee:
Lucent Technologies Inc. - Murray Hill NJ
International Classification:
H01M 210
US Classification:
429187
Abstract:
The present invention provides, in one embodiment, a battery container. In this particular embodiment, the container comprises a housing having side walls and a spacing ridge formed in and extending outwardly from the side walls. The spacing ridge forms a groove on an interior surface of the walls and has a slot formed in the spacing ridge at first and second opposing ends of the housing. In an alternate embodiment, the spacing ridge has a plurality of slots formed on opposing ends of the container. Typically, two adjacent slots are formed on each end such that opposing ends of the handle may engage the retaining pin through the slots. The container further comprises a handle and a retaining pin configured to be received within the interior groove adjacent the slot. The handle is cooperatively engageable with the retaining pin to provide a lifting point for the container when the retaining pin is received in the interior groove. The handle and the retaining pin work cooperatively together to provide a handle that can easily be removed from the container, if so desired.
