Document Type and Number:
WIPO Patent Application WO/2023/120713
Kind Code:
A1
Abstract:
This switch control device is for controlling the operation of a switch device for switching states of electrical connection between a power storage unit of a power storage device and a power terminal of the power storage device. The switch control device comprises: a first determination unit that determines whether the voltage of the power storage unit has reached a preset first threshold; a first signal output unit that outputs a first signal for providing an advance notice that the power storage unit and the power terminal will be electrically disconnected, when the voltage of the power storage unit is determined to have reached the first threshold; and a second signal output unit that outputs to the switching device a second signal for electrically disconnecting the power storage unit and the power terminal, when a disconnection permission condition, which is the condition for permitting the power storage unit and the power terminal to be electrically disconnected, is satisfied after the first signal output unit outputs the first signal.
