Title:
STORAGE BATTERY, BATTERY UNIT, AND BATTERY MONITORING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/047925
Kind Code:
A1
Abstract:
A storage battery 10 comprises: a positive electrode layer; a negative electrode layer; and a separator that is disposed between the positive electrode layer and the negative electrode layer. The separator is provided in a form containing a substance that has a dielectric constant which changes according to the temperature. A battery unit 30 comprises: a calculation unit 31 that applies AC signals to a positive electrode terminal 14 and a negative electrode terminal 15 of the storage battery 10, and calculates a dielectric constant or a capacitor capacity on the basis of the response signals; and a temperature monitoring unit 32 that monitors the internal temperature of the storage battery 10 on the basis of the dielectric constant or the capacitor capacity which has been calculated by the calculation unit 31.
