Title:
管理装置、及び蓄電システム
Document Type and Number:
Japanese Patent JP6876994
Kind Code:
B2
Abstract:
A voltage detection unit detects voltage between both ends of a power storage unit. A current detection unit detects current flowing through the power storage unit. A control unit estimates a state of charge (SOC) of the power storage unit using an open circuit voltage (OCV) method based on the voltage detected by the voltage detection unit and estimates the SOC of the power storage unit using a current integration method based on the current detected by the current detection unit. The control unit compares the SOC estimated using the OCV method with the SOC estimated using the current integration method to determine whether micro short circuit occurs in the power storage unit.
