Battery pack of automatically setting master and slave pack, multi-battery pack system including the same and method for controlling the same
First Claim
1. A battery pack constructing a multi-battery pack system, the battery pack comprising:
- a communication line for providing a pathway for communication of the battery pack with other battery packs; and
a controller for checking if the communication line is maintained at a first level for a first desired amount of time when an activation signal or a message of setting a master battery pack is received, outputting signals of a second level to the communication line for a second desired amount of time when the communication line is maintained at the first level for the first desired amount of time, and setting the battery pack as the master battery pack.

Abstract
Disclosed are a multi-battery pack system, a method for controlling battery packs, and a battery pack, in which plural battery packs provided in the multi-battery pack system can be set as a master battery pack and slave battery packs by themselves. The method for controlling the battery packs constructing the multi-battery pack system includes: a first step of checking if a communication line is maintained at a first level for a first desired amount of time when an activation signal or a message of setting a master battery pack is received; and a second step of outputting signals of a second level to the communication line for a second desired amount of time when the communication line is maintained at the first level for the first desired amount of time, and setting a battery pack as a master battery pack.
