Title:
PARALLEL CHARGING CONTROL METHOD FOR MULTIPLE BATTERY PACKS, AND ENERGY STORAGE DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/050964
Kind Code:
A1
Abstract:
A parallel charging control method for multiple battery packs, comprising: respectively calculating charging current differences between required charging currents of battery packs and actual charging currents of the battery packs, and determining the battery pack having the smallest charging current difference as a reference battery pack; according to the required charging current of the reference battery pack and the actual charging currents of the battery packs, calculating target charging currents of the battery packs during a parallel charging steady state; determining a target parallel charging current according to the target charging currents of the battery packs; and generating a target charging instruction according to the target parallel charging current, and sending the target charging instruction to a power supply.
