Title:
BATTERY UNIT AND POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/210123
Kind Code:
A1
Abstract:
A battery unit 22a includes: a first connection terminal 41; a second connection terminal 48 configured so as to be connectable to a storage battery 42; a power conversion circuit 43 connected between the first connection terminal 41 and the second connection terminal 48; and a control circuit 44 that controls the power conversion circuit 43 and is configured so as to be able to measure the terminal voltage value V41 of the first connection terminal 41 and the current Ia flowing from the power conversion circuit 43 to the second connection terminal 48. The control circuit 44 compares the terminal voltage value V41 with a first threshold value in a state in which the current Ia flows from the power conversion circuit 43 to the second connection terminal 48 and, when the terminal voltage value V41 passes across the first threshold value, controls the power conversion circuit 43 so as to decrease the current Ia flowing from the power conversion circuit 43 to the second connection terminal 48 until the terminal voltage value V41 passes across the first threshold value again.
