Document Type and Number:
WIPO Patent Application WO/2024/101682
Kind Code:
A1
Abstract:
The present invention relates to a battery system and a parallel packs control method using same. The battery system comprises: a plurality of battery packs connected in parallel; a plurality of switches connected in series to one of both ends of each of the plurality of battery packs; a battery monitoring integrated circuit (BMIC) that obtains state information including a plurality of pack voltages for the plurality of battery packs; a main control unit (MCU) that generates a plurality of candidate groups including at least one battery pack from among the plurality of battery packs on the basis of the plurality of pack voltages, estimates the capacity of each of the plurality of battery packs on the basis of the state information, determines a final connection group to perform a power operation from among the plurality of candidate groups on the basis of the capacity of each of the plurality of battery packs, and transmits a pack control signal to the BMIC so as to turn on a switch connected to a battery pack belonging to the final connection group from among the plurality of switches.
