Document Type and Number:
Japanese Patent JP7168336
Kind Code:
B2
Abstract:
The present invention optimizes an SOC use range during operation of a secondary battery system. An assembled battery control unit 150 functions as a secondary battery control device for controlling an assembled battery that is a secondary battery. The assembled battery control unit 150 is provided with: an SOC estimation unit 152 for estimating the state of charge (SOC) of the assembled battery; a voltage drop calculation unit 153 for calculating a voltage drop based on an open-circuit voltage (OCV) and a closed circuit voltage (CCV) of the assembled battery; and a use SOC determination unit 154 for determining, on the basis of the relationship between the SOC estimated by the SOC estimation unit 152 and the voltage drop calculated by the voltage drop calculation unit 153, an SOC range to be used during charging/discharging of the assembled battery.
