Title:
SHUT-OFF DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/013842
Kind Code:
A1
Abstract:
Provided is a shut-off device for a vehicle, the device being capable of operating so as to further draw out the durability performance of a switch. The shut-off device (1) comprises a first switch (33A) that switches an electrical power path (11), which is a route for transmitting electrical power based on a power supply unit (10), between a conductive state and a shut-off state. The shut-off device (1) comprises a control unit (15) that executes a degradation determination process for comparing a resistance value (R) of the first switch (33A) with a resistance threshold value (Th1). When the resistance value (R) is greater than or equal to the resistance threshold value (Th1), the control unit (15) determines that the first switch (33A) is in a degraded state, and sends a notification of the degraded state to the outside.
