Abstract
Disclosed is a method for setting sequential ID to a multi-slave BMS in a battery pack, the battery pack including N (N: natural number of 2 or more) slave BMSs having sequential physical locations to control a battery module containing at least one battery and a main BMS to control the N slave BMSs.
Claims17
A method for setting sequential identification (ID) to a multi-slave battery management system (BMS) in a battery pack, the battery pack including N (N:
- natural number of 2 or more) slave BMSs having sequential physical locations to control a battery module containing at least one battery and a main BMS to control the N slave BMSs, the method comprising:
- the main BMS transmitting a trigger signal to a first slave BMS to initialize ID setting;
- the first slave BMS receiving the trigger signal and transmitting ID information of the first slave BMS to the main BMS and the trigger signal to a next slave BMS;
- sequentially performing a process of receiving the trigger signal and transmitting slave BMS ID information to the main BMS and the trigger signal to a next slave BMS throughout the second slave BMS to the N−1th slave BMS;
- and
- the Nth slave BMS receiving the trigger signal and transmitting ID information of the Nth slave BMS to the main BMS.

- a first slave BMS to receive the trigger signal and transmit ID information of the first slave BMS to the main BMS and the trigger signal to a next slave BMS;
- at least one slave BMS to receive the trigger signal and sequentially performing the transmission of ID information of each slave BMS to the main BMS and the trigger signal to a next slave BMS;
- and
- an Nth slave BMS to receive the trigger signal and transmit ID information of the Nth slave BMS to the main BMS.
