Title:
PARALLEL BATTERY SYSTEM AND METHOD OF PREDICTING REMAINING CHARGE TIME THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/068569
Kind Code:
A1
Abstract:
The present invention relates to a parallel battery system and a method for predicting the remaining charging time thereof, in which, in prediction of a remaining time for charging multiple battery packs connected in parallel to a final target SOC, a BMS estimates SOCs of the respective multiple battery packs and assigns ordering numbers in ascending order of the SOCs, determines, from among the multiple battery packs, a connected pack group including n (n is a natural number) battery packs which are connected to a charging device due to a relay being closed and a use pack group including m (m is a natural number) battery packs which are not connected to the charging device due to the relay being open, predicts a first remaining charging time required for a battery pack having the largest ordering number from among the n battery packs to reach the final target SOC, calculates a second remaining charging time by adding m remaining charging times predicted for the respective m battery packs, and predicts a final remaining charging time by adding the first remaining charging time and the second remaining charging time.
