Title:
BATTERY MANAGEMENT DEVICE AND METHOD FOR ESTIMATING BATTERY INTERNAL TEMPERATURE
Document Type and Number:
WIPO Patent Application WO/2024/019465
Kind Code:
A1
Abstract:
Embodiments of the present specification relate to a method and a device for estimating an internal temperature of a battery by using impedance of a specific frequency band. A battery management device according to an embodiment of the present specification may comprise: an impedance measurement unit that measures impedance of a battery for each frequency band; and a controller that controls the impedance measurement unit to apply a signal of a configured frequency band to the battery, receives a configured impedance corresponding to the configured frequency band from the impedance measurement unit, and inputs the configured impedance to a learning model so as to estimate an internal temperature of the battery, wherein the configured frequency band is determined by a correlation between the impedance for each frequency band and a state of charge (SOC).
