Abstract

A battery pack includes a battery module including a battery cell and configured to perform a first identification function for enabling a device outside the battery module to recognize characteristics of the battery cell, and a battery management system for controlling operations of the battery cell and configured to perform a second identification function for enabling a device outside the battery management system to recognize a type of the battery management system.

Claims

1. A battery pack comprising:

a battery module comprising a battery cell and configured to perform a first identification function for enabling a device outside the battery module to recognize characteristics of the battery cell; and

a battery management system for controlling operations of the battery cell and configured to perform a second identification function for enabling a device outside the battery management system to recognize a type of the battery management system, the battery management system being coupled between the battery module and the device outside the battery management system and being detachable from the battery module.

2. The battery pack of claim 1, wherein the battery management system is configured to recognize the characteristics of the battery cell by using the first identification function of the battery module.

3. The battery pack of claim 1, wherein the battery module further comprises an identifying unit configured to perform the first identification function.

4. The battery pack of claim 3, wherein the identifying unit is a memory for recording a state of the battery cell.

5. The battery pack of claim 4, wherein the battery management system is configured to reset data about a previous battery module when the battery module is installed.

6. The battery pack of claim 4, wherein the battery management system is configured to update the state of the battery cell recorded by the memory.

7. The battery pack of claim 1, wherein whether battery cells are connectable to the battery management system is determined according to their characteristics and according to the type of the battery management system.

8. The battery pack of claim 1, wherein the device outside the battery module is electrically coupled to the battery pack.

9. A battery management system for controlling operations of a battery module comprising a battery cell, wherein the battery management system is configured to perform an identification function for enabling an external device to which the battery management system is coupled to recognize a type of the battery management system, wherein the battery management system is configured to be coupled between the battery module and the external device and is configured to be detachable from the battery module.

10. The battery management system of claim 9, further comprising an identifying unit for performing the identification function and for communicating with the external device.

11. The battery management system of claim 9, wherein whether the battery module is connectable to the battery management system is determined according to its characteristics.

12. The battery management system of claim 11, further comprising a recognizing unit for recognizing the characteristics of the battery module.

13. A battery system comprising:

a battery module comprising a battery cell;

a battery management system for controlling operations of the battery cell; and

a host for identifying a type of the battery management system by being coupled to the battery management system, the battery management system being coupled between the host and the battery module and being detachable from the battery module.

14. The battery system of claim 13, wherein whether the battery management system is connectable to the host is determined according to the type of the battery management system and according to a type of the host.

15. The battery system of claim 13, wherein the host is configured to identify a type of the battery module by being coupled to the battery module.

16. The battery system of claim 15, wherein the battery management system is configured to control operations of the battery module when the host identifies the battery module as satisfying a condition.

17. The battery system of claim 13, wherein the battery module further comprises a memory for recording a state of the battery cell.

18. The battery system of claim 13, wherein the battery management system is configured to identify a type of the battery module.
