Abstract

Wireless battery control system and method and a battery pack are provided. The system comprises: a master; and a plurality of slaves positioned sequentially such that the distances from the master are different from one another. The master wirelessly transmits a ready signal when entering into an ID allocation mode. Each of the slaves wirelessly transmits the RSSI of the ready signal to the master when the ready signal is wirelessly received from the master or another slave during operation in standby mode. The master wirelessly transmits an ID associated with an operation count to a slave which has wirelessly transmitted the maximum RSSI among the RSSIs of the ready signal, and increases the operation count by 1.

Description

technical field [0001] The present disclosure relates to a wireless battery control system, method, and battery pack, and more particularly, to a wireless battery for sequentially assigning an ID associated with the location of each slave management module to multiple slave management modules Control system, method and battery pack. [0002] This application claims priority to Korean Patent Application No. 10-2018-0021224 filed in Korea on February 22, 2018 and Korean Patent Application No. 10-2019-0016885 filed in Korea on February 13, 2019, which The disclosure is hereby incorporated by reference. Background technique [0003] Recently, the demand for portable electronic products such as notebook computers, video cameras, and mobile phones has increased dramatically, and with the widespread development of electric vehicles, energy storage batteries, robots, and satellites, a lot of research is being done on high-performance batteries that can be repeatedly recharged.
