US Patent:
8264200, Sep 11, 2012
Filed:
May 15, 2009
Appl. No.:
12/466871
Inventors:
Karthik Kadirvel - Melbourne FL, US
Umar Jameer Lyles - Palm Bay FL, US
Assignee:
Texas Instruments Incorporated - Dallas TX
International Classification:
H02J 7/00
US Classification:
320116
Abstract:
Various apparatuses and methods for detecting cell connection status of a multi-cell battery are disclosed herein. For example, some embodiments provide an apparatus for detecting cell connection status of a multi-cell battery. The apparatus includes a battery cell input for each cell, a cell connection status detector for each cell, and at least one comparator. Each of the cell connection status detectors is connected to a battery cell input and has a current-based status indicator output. The at least one comparator is connected to the current-based status indicator outputs. Each of the plurality of cell connection status detectors floats in a different supply voltage range. The at least one comparator is referenced to a lower voltage potential than at least one of the plurality of cell connection status detectors.

Systems And Methods For Analog To Digital Converter Charge Storage Device Measurement

View page
US Patent:
8378868, Feb 19, 2013
Filed:
Nov 4, 2010
Appl. No.:
12/939486
Inventors:
Umar Jameer Lyles - Palm Bay FL, US
Bertan Bakkaloglu - Scottsdale AZ, US
Assignee:
Texas Instruments Incorporated - Dallas TX
International Classification:
H03M 3/00
H02J 7/00
US Classification:
341143, 320134, 320136
Abstract:
Systems and methods for analog to digital conversion charge storage device measurement are presented. In multi-cell charge storage device monitoring systems, accurate measurement of cell voltages is used for protection of the multi-cell device. The disclosed cell referenced solution converts the cell voltage to a digital representation referenced at the cell voltage. The digital representation referenced to the cell voltage is then level shifted to a ground referenced signal suitable for digital post processing. This processing may be used for fault detection of over-voltage, under-voltage, open cell, and similar fault conditions and cell capacity measurements. An example embodiment implements a sigma delta modulator to perform the signal transformation from analog to digital. The disclosed systems and methods may be differential and stackable for multiple cells.

Voltage Monitoring Using Bitstream Signal Processing

View page
US Patent:
8436620, May 7, 2013
Filed:
Sep 2, 2010
Appl. No.:
12/874911
Inventors:
Gary Lee Stirk - West Melbourne FL, US
Brian Allen - Grant FL, US
Umar Jameer Lyles - Palm Bay FL, US
John Houldsworth - Reston VA, US
Bertan Bakkaloglu - Scottsdale AZ, US
Assignee:
Texas Instruments Incorporated - Dallas TX
International Classification:
G01N 27/416
US Classification:
324433, 324434, 324426
Abstract:
Systems and methods are provided for monitoring a voltage. A level shifter is configured to generate a current proportional to the voltage of the battery cell. A delta-sigma modulator is configured to convert the current into a first density modulated bitstream representing the voltage of the battery cell. A first reference source is configured to provide a second density modulated bitstream representing a first threshold voltage. A first comparator is configured to compare the first density modulated bitstream and the second density modulated bitstream.

Systems And Methods Of Battery Cell Anomaly Detection

View page
US Patent:
20100173183, Jul 8, 2010
Filed:
Jan 6, 2009
Appl. No.:
12/349039
Inventors:
Karthik Kadirvel - Gainesville FL, US
Umar Jameer Lyles - Palm Bay FL, US
Assignee:
Texas Instruments Incorporated - Dallas TX
International Classification:
G01N 27/416
H01M 6/02
H01M 8/04
H01M 10/48
US Classification:
429 90, 324434, 702 63
Abstract:
Systems and methods for cell anomaly detection are provided. The disclosed systems and methods of cell anomaly detection may use a single circuit to detect both cell-open and imbalance conditions. Disclosed embodiments may incorporate a continuous or a sampled time system (i.e. cell anomaly detection is performed when an enable signal is active). An example embodiment includes receiving voltages of a plurality of cells of a battery pack; converting the received voltages to currents; determining a maximum current of the currents; determining whether at least one of the currents is anomalous; and reporting the at least one anomalous current as indicative of a bad cell.

Systems And Methods Of Overvoltage And Undervoltage Detection

View page
US Patent:
20100225300, Sep 9, 2010
Filed:
Mar 6, 2009
Appl. No.:
12/399361
Inventors:
Umar Jameer Lyles - Palm Bay FL, US
Karthik Kadirvel - Melbourne FL, US
Assignee:
TEXAS INSTRUMENTS INCORPORATED - Dallas TX
International Classification:
G01R 19/00
US Classification:
324 7611
Abstract:
Systems and methods for overvoltage and undervoltage detection are provided. The disclosed systems and methods of overvoltage and undervoltage detection may be implemented with a fully differential circuit that includes a coarse comparator and a band gap based fine comparator. The coarse comparator may determine if the battery is closer to an OV condition or an UV condition. Based on the output of the coarse comparator, the trip point of the fine comparator is adjusted. The outputs of both comparators are pull-up circuits whose output is decoded to determine if an OV or a UV condition has occurred. The disclosed systems and methods of overvoltage and undervoltage detection accomplish valid circuit outputs even when the voltage across the battery reduces to zero volts. This may be achieved by using an active low signal for the UV condition and an active high signal for the OV condition. Thus, when the battery voltage goes to zero, the circuit evaluates to the correct output.

Current Based Overvoltage And Undervoltage Detector

View page
US Patent:
20110012605, Jan 20, 2011
Filed:
Dec 21, 2009
Appl. No.:
12/643766
Inventors:
Umar J. Lyles - Palm Bay FL, US
Karthik Kadirvel - Melbourne FL, US
Assignee:
Texas Instruments Incorporated - Dallas TX
International Classification:
G01N 27/416
G01R 19/00
US Classification:
324433, 327 62
Abstract:
With batteries or cells, particularly lithium ion cells, it is important to determine when one or more cells have entered a fault condition (i.e., overvoltage or undervoltage). Conventional circuits employ measuring circuits that use multiple bandgap circuits and high voltage components. These conventional circuits, however, consume a great deal of area because of the use of these multiple bandgap circuits and the high voltage components. Here, a circuit is provided that reduces the number of bandgap circuits and reduces the number of high voltage components, reducing the area consumed and reducing the overall cost of production compared to conventional circuits.
