A provisioning device includes a communication module capable of communicating with a plurality of battery management systems included in the battery pack; and a processor, wherein the processor causes the communication module to wirelessly transmit a provisioning signal for switching at least one battery management system of the plurality of battery management systems to a provisioning mode, receives state information of the battery and the battery management system from the plurality of battery management systems through the communication module, and assigns an ID of a network of the battery pack and an ID of each of the battery management system based on the state information of the battery management system received through the communication module.

Provisioning device and method for battery state diagnosis and ID assignment

A battery module, an upper-level battery management system (BMS), and an automatic identification (ID) assignment system of a battery module are provided. A battery module, configured to wirelessly communicate with an upper-level battery management system (BMS) and be inserted into at least one battery module mounting part formed in a battery rack, includes: a pressure detection unit provided on a predetermined surface part of the battery module, the pressure detection unit being configured to: detect a pressure applied to the predetermined surface part, and output a pressure value, a wireless communication unit configured to transmit a pressure detection signal including the pressure value to the upper-level BMS through wireless communication, and a control unit configured to set and register a received identification (ID) information as its own ID when the ID information automatically assigned from the upper-level BMS is received.

Automatic ID assignment system and method for battery module

A system for detecting a defective battery using wireless communications. The system includes first sensors and a first master device. The first sensors are matched on a 1:1 basis with first battery modules to monitor the first battery modules. The first master device communicates with the first sensors. The respective first sensors each include a first monitoring circuit which collects a primary data on a 1:1-matched first battery module in a monitoring mode, and a first communicating circuit which outputs the primary data to the first master device in a communicating mode. The first monitoring circuit is turned off in the communicating mode. The first communicating circuit is turned off in the monitoring mode.

System and method for detecting a defective battery using wireless communications

Discussed is a system for managing a battery, the system including a wireless communication unit that communicates with a first upper-level battery management system performing communication using a first communication channel, a communication abnormality detection unit that detects a communication abnormality of the first upper-level battery management system, and a channel change unit that changes the communication channel of the wireless communication unit to a second communication channel different from the first communication channel when the communication abnormality of the first upper-level battery management system is detected by the communication abnormality detection unit.

System and method for managing battery

Disclosed is a master battery management system (BMS) including: a transmission unit for transmitting a cell balancing start command signal and a temperature measurement command signal to a plurality of slave BMSs; a wired communication unit for transmitting a FAN ON signal to a plurality of fans after the transmission unit wirelessly transmits the cell balancing start command signal; a reception unit for receiving an association signal from an associated slave BMS having a difference in temperature of a printed circuit board (PCB) board of a corresponding slave BMS and a temperature of a PCB substrate of a corresponding slave BMS that is greater than a preset value; and a control unit for determining that the associated slave BMS is disposed in the same rack, and changing an ID and communication channel of the associated slave BMS to a specific value.

System for automatically assigning ID to slave BMS

A battery system includes a battery pack having a metal housing capable of accommodating a plurality of battery modules, a plurality of slave battery management systems configured to manage the plurality of battery modules, and a master battery management system installed outside the metal housing to wirelessly communicate with a first battery management system among the plurality of slave battery management systems, wherein the first slave battery management system which communicates with the master battery management system is installed at a boundary of the metal housing so as not to be shielded with the metal housing.

Slave battery management system at a boundary of metal housing and battery system including the same

A cell management controller including a first antenna capable of communicating with an external device using a first frequency, a second antenna capable of receiving a signal of a second frequency from the external device, a voltage generation unit configured to generate a voltage based on the signal of the second frequency received at the second antenna; a driving unit configured to receive a signal based on a voltage generated by the voltage generation unit as an enable signal, and a cell parameter measurement unit configured to measure a parameter indicating a state of a battery cell based on a control signal from the driving unit, wherein the driving unit transitions from a standby state to a wake-up state based on the enable signal.
