Abstract

The battery analyzer/conditioner system includes a battery analyzer/conditioner having an input port and an output port. The battery analyzer/conditioner operates to analyze, condition and test a group of rechargeable batteries. A cable is coupled between the input port and a remote control unit to transmit signals between the battery analyzer/conditioner and the remote control unit to enable the remote control unit to control the operation of the battery analyzer/conditioner. Another battery analyzer/conditioner also having an input port and an output port communicates with the battery analyzer/conditioner via a cable coupled between the output port of the battery analyzer/conditioner and the input port of the second battery analyzer/conditioner, wherein the first and second battery analyzer/conditioners are connected in a daisy chain network to permit the remote control unit to communicate selectively with any one of the battery analyzer/conditioner units.

Claims

1. A battery management system for use with rechargeable batteries, comprising:

power systems management means for enabling a group of the batteries to be managed for determining the performance characteristics of the batteries in said group, and for enabling the batteries in said group to be diagnosed, repaired, and manufactured;

wherein said management means stores selectable management parameters for each one of the batteries in said group, and further controls the diagnosing, repairing, and manufacturing of each one of the batteries in said group according to said parameters to facilitate the management of the batteries;

wherein said management means generates source command signals for enabling each one of the batteries in said group to be diagnosed, repaired, and manufactured, and further generates source information signals indicative of the charge state of each one of the batteries in said group and indicative of said parameters;

buss means coupled to said management means for facilitating the remote control of said management means; and

control unit means coupled to said buss means for generating remote command signals to cause said management means to generate said source command signals in response to said remote command signals for controlling remotely the operation of said management means, and for generating remote information signals indicative of the state of the batteries in response to said source information signals.

2. A battery management system according to claim 1, wherein said management means further generates remote selection signals to facilitate the selection of said parameters.

3. A battery management system according to claim 2, wherein said control unit means includes a port means for coupling said buss means to said control unit means to enable it to transmit said remote command signals and to receive said source information signals.

4. A battery management system according to claim 3, wherein said management means further includes an input port means for coupling said buss means to said management means to enable it to transmit said source information signals and to receive said remote command signals.

5. A battery management system according to claim 4, further including another power systems management means for analyzing and conditioning another group of the batteries, said another management means for storing additional selectable management parameters for each one of the batteries in said another group;

wherein said another management means generates another source command signal for enabling each one of the batteries in said another group to be analyzed and conditioned, and said another management means further generates another source information signal indicative of the charge state of each one of the batteries in said another group and indicative of said additional parameters; and

another buss means for coupling said another management means to the first-mentioned management means for controlling remotely the operation of the first mentioned and said another management means.

6. A battery management system according to claim 5, wherein said another management means further includes another input port means for facilitating the communication of said remote command signal and said another source information signal;

the first-mentioned management means further includes an output port means for enabling said another management means to communicate with the first mentioned management means.

7. A battery management system according to claim 6, wherein the first mentioned management means further includes a printer port means for exporting said source information signal and said another source information signal to enable said signals to be reproduced in a printed form.

8. A system according to claim 1, wherein said power systems management means includes a battery management unit.

9. A battery management system for use with rechargeable batteries, comprising:

a plurality of power systems management units each having a control input port and a control output port, each one of said management units for analyzing and conditioning a plurality of rechargeable batteries;

network cable means interconnecting in communication the control input of one management unit with control output of another management unit to provide a daisy chain network;

remote control means for sending control commands to individual ones of the management units to cause them to analyze/condition individual ones of the batteries connected thereto; and

remote control cable means interconnecting an output port of said remote control means to the input port of an initial one of said management units to facilitate the sending of information from said remote control means to individual ones of said management units.

10. A system according to claim 9, wherein said remote control means further includes a display so that information from individual ones of the management units regarding individual batteries can be displayed.

11. A system according to claim 9, wherein said cable means includes a plurality of lines for providing two-way communication.

12. A system according to claim 11, wherein said lines comprise nine individual lines.

13. A system according to claim 9, wherein an adjacent one of said management units includes means for supplying activating power to said remote control means via said cable means for powering it.

14. A system according to claim 9, wherein each one of the management units includes a computer processing unit.

15. A system according to claim 9, wherein said remote control means includes a computer processing unit.

16. A system according to claim 9, wherein each one of said management units includes bar code reader means for providing additional information for the system.

17. A system according to claim 9, wherein said remote control means sends protocol messages to each one of the management units via said cable means, and said individual management units communicating via said cable means with said remote control means with their protocol messages.

18. A system according to claim 9, further including supplying unit activating power from an adjacent one of the management units via said remote control cable means to said remote control means for powering it.

19. A system according to claim 9, wherein said power systems management units include a battery management unit.

20. A method of using a battery management system for rechargeable batteries, comprising:

using a plurality of power systems management units each having a control input and a control output, each one of said management units for analyzing and conditioning a plurality of rechargeable batteries;

interconnecting in communication the control input of one management unit with control output of another management unit with cable means to provide a daisy chain network;

sending control commands from a remote control means to individual ones of the management units to cause them to analyze/condition individual ones of the batteries connected thereto; and

interconnecting an output of said remote control means to the input of an initial one of said management units to facilitate the sending of information from said remote control means to individual ones of said management units.

21. A method according to claim 20, further including displaying at said remote control means information from individual ones of the management units regarding individual batteries can be displayed.

22. A system according to claim 20, further including providing two-way communication over said cable means.
