Title:
蓄電池管理装置および電池装置の管理方法
Document Type and Number:
Japanese Patent JP7470823
Kind Code:
B2
Abstract:
This storage battery management device that manages a battery assembly having a plurality of storage batteries connected in series is provided with a control unit, an activation switch, and a power supply activation circuit that turns the activation switch on when an external activation signal becomes an activation logic and maintains the switch in the on state as long as an activation maintenance signal is being input. The control unit has a line switch control unit, an activation maintenance control unit, and an OCV identification unit. The line switch control unit turns a line switch on when the external activation signal becomes an activation logic. The activation maintenance control unit initiates output of the activation maintenance signal to the power supply activation circuit when the external activation signal becomes an activation logic. The OCV identification unit acquires an amount of change in voltage of each storage battery at predetermined time intervals when the external activation signal becomes a stop logic, and when all of the amounts of change in voltage become equal to or less than a predetermined amount of change, records the voltages of the storage batteries as OCV, and stops output of the activation maintenance signal.
