Title:
BATTERY SYSTEM FOR SEQUENTIAL CHARGING OF BATTERIES AND CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/010254
Kind Code:
A1
Abstract:
A battery system according to an embodiment of the present invention may comprise: multiple battery packs; and a battery control device for collecting voltage values of the respective multiple battery packs, and controlling charging of the multiple battery packs on the basis of the collected voltage values. The battery control device may determine a charging group by selecting one or more battery packs having a voltage value within a predefined threshold range, and perform control such that the battery packs included in the charging group are charged together to a predefined target voltage. Here, when charging to the target voltage is completed, the battery control device may update the charging group by selecting battery packs having the voltage value of the charging group and the voltage value within the predefined threshold range from among battery packs that have not been charged.
