An battery data management method according to an embodiment disclosed herein includes transmitting, by a terminal, battery-related information of a battery to an authentication server to obtain a public key and a first message, encrypting by the terminal, a first message with the public key, and transmitting, by the terminal, the encrypted first message to a processor, decrypting, by the processor, the encrypted first message using a previously stored first key to obtain the first message, generating, by the processor, a second message based on random number information, encrypting, by the processor, the second message with the first key, and transmitting, by the processor, the encrypted second message to the terminal, decrypting, by the terminal, the second message with the public key to obtain the second message and transmitting, by the terminal, the first message and the second message to the authentication server.

Battery data management system and operating method thereof

The present disclosure provides a battery management system including a reception unit configured to receive a start signal and a completion signal of job from another battery management system, a transmission unit configured to transmit the start signal and the completion signal of job by broadcast, a storage unit configured to store a time table including a job code of a plurality of jobs to be executed, a priority of corresponding job, and an execution time and period of corresponding job, a synchronization unit configured to execute synchronization of a job execution time using the received start signal or the received completion signal of job and the time table, and a job execution unit configured to execute a job using the time table stored in the storage unit and a time calculated by the synchronization unit.

Battery management system

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

A battery management system in which each of a plurality of battery management systems performs an individual task and transmits results of the tasks to a master battery management system wirelessly, the battery management system including: a task information storage unit including a list of tasks performed by each of the plurality of battery management systems, the performance time, performance cycle, and work priority of each task included in the list of tasks, and the communication priority among the plurality of battery management systems, a schedule determination unit configured to determine a work schedule on the basis of data stored in the task information storage unit, and a priority changing unit configured to adjust the work priority of a task based on the work schedule determined by the schedule determination unit, wherein the schedule determination unit is further configured to adjust the work schedule according to the adjusted work priority.
