Title:
CONTROL DEVICE FOR IN-VEHICLE POWER SOURCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/125193
Kind Code:
A1
Abstract:
A control device (21) for an onboard power source device is applied to an onboard power source device comprising: a storage battery (11) connected to an electric apparatus (14); a switch (SW1) provided to an electric route (L1) joining the storage battery and the electric apparatus; and a first voltage sensor (25) and second voltage sensor (26) that detect a voltage that is on the storage-battery side, among the two ends of the switch. When the voltage that is on the storage-battery side, among the two ends of the switch, is a prescribed overvoltage, turning the switch on is prohibited. The control device comprises a voltage acquisition unit that acquires a first voltage detected by the first voltage sensor and a second voltage detected by the second voltage sensor, and a switch control unit that allows the switch to be turned on when one of the first voltage and the second voltage is a normal value and the other is an overvoltage value.
