Abstract

A method and apparatus for the intelligent management of multi-cell battery pack. A battery management system which may be mounted on board a vehicle facilitates battery management including monitoring the state of charge of the battery pack. Wireless communication equipment facilitate communication between the battery management system to a remote location. A battery charger controlled by the battery management system charges individual cells of the battery pack.

Claims

1. An intelligent battery management system for mounting on board mobile equipment, comprising:

central stationary remote user access;

a battery pack having a series of cells mounted on mobile equipment for helping propel the equipment along the ground;

mobile battery management system mounted on board mobile equipment for facilitating battery management including, monitoring the state of charge of the battery pack;

wireless communication equipment for facilitating communication between the mobile battery management system and the central stationary remote user access;

a battery charger controlled by the battery management system for charging individual cells of the battery pack;

at least one sensor for monitoring load current from the battery pack and for supplying current data to the battery management system;

a load controller for facilitating load current in response to the battery management system; and

wherein the wireless communication equipment communicates the condition of the battery pack and the management of it to the remote user access.

2. The system according to claim 1, further including the battery management system including converters for monitoring individual cells of the battery pack.

3. The system according to claim 2, further including a temperature sensor for monitoring the temperature of the cells, and a cell temperature measurement unit responsive to the temperature sensor for measuring the temperature, voltage or current of individual cells.

4. The system according to claim 3, further including an operator control for an operator of the mobile equipment for receiving messages from the battery management system regarding the state of parameters of the cells.

5. The system according to claim 4, further including a part of the battery management system for supplying data, and a local display/keypad unit for receiving the data.

6. The system according to claim 4, further including a portable computer part of the battery management system.

7. The system according to claim 4, wherein the wireless communication equipment includes a wireless communication module for downloading data collected and stored by the battery management system.

8. An intelligent battery management system, comprising:

a battery pack having a series of cells;

a battery management system for facilitating battery management including monitoring the state of charge of the battery pack;

wireless communication equipment for facilitating communication between the battery management system to a remote location; and

a battery charger controlled by the battery management system for charging individual cells of the battery pack.

9. The system according to claim 8, wherein the battery management system includes converters for monitoring individual cells of the battery pack.

10. The system according to claim 9, further including a temperature sensor for monitoring the temperature of the cells, and a cell temperature measurement unit responsive to the temperature sensor for measuring the temperature, voltage or current of individual cells.

11. The system according to claim 10, further including an operator control for use by an operator of the mobile equipment for receiving messages from the battery management system regarding the state of parameters of the cells.

12. The system according to claim 11, further including a part of the battery management system for supplying data, and a local display/keypad unit for receiving the data.

13. The system according to claim 11, further including a portable computer part of the battery management system.

14. The system according to claim 11, wherein the wireless communication equipment includes a wireless communication module for downloading data collected and stored by the battery management system.

15. A method of managing batteries employed on a number of vehicles, comprising:

facilitating wireless communication between mobile battery management systems and a central stationary remote user access;

using the remote user access to receive and send battery performance data.

16. A method according to claim 15, further including controlling, using the battery management system, either locally or remotely, a battery charger to prevent individual cells from exceeding a maximum voltage specification during charging.
