Title:
STORAGE BATTERY SYSTEM, DETERIORATION DETERMINATION DEVICE, AND DETERIORATION DETERMINATION METHOD
Document Type and Number:
Japanese Patent JP2022069223
Kind Code:
A
Abstract:
To provide a storage battery system capable of accurately determining deterioration of a storage battery.SOLUTION: An approximate expression derivation unit (12) derives, on the basis of internal resistance values in time series calculated by an internal resistance value calculation unit (11), an approximate expression for approximating an internal resistance value of a storage battery (2). An approximate expression calculation unit (13) uses the approximate expression derived by the approximate expression derivation unit (12) to calculate the internal resistance value of the storage battery (2). A deterioration determination unit (17) determines deterioration of the storage battery (2) by comparing the internal resistance value of the storage battery (2) calculated by the approximate expression calculation unit (13) with a determination value.SELECTED DRAWING: Figure 1
