Document Type and Number:
Japanese Patent JP2023151056
Kind Code:
A
Abstract:
To provide a relay abnormality determination device and a system capable of determining abnormality on multiple relays that are connected in series with a drive unit that turns on and off the multiple relays, and which are connected to each other in parallel.SOLUTION: A first relay 31 and a second relay 32 are connected to each other and are connected to a drive unit 40 in series. A relay abnormality determination device 60 in a relay abnormality determination system 1 is configured to determine an abnormality on the first relay 31 and the second relay 32 on the basis of decrease in a current flowing through the drive unit 40 via the first relay 31 and the second relay 32 when the first relay 31 and the second relay 32 are normal.SELECTED DRAWING: Figure 1
