Abstract: One or more embodiments provide a switch diagnosis device including: a switch in a current path at a high voltage side; a voltage-sensing circuit configured to generate a voltage signal by sensing a voltage across the switch at the high voltage side; a current-sensing circuit configured to generate a current signal by detecting a current flowing through the current path; a controller configured to: receive the voltage signal and the current signal, calculate contact resistance of the switch based on the received voltage signal and the received current signal, and diagnose a deterioration state of the switch based on the calculated contact resistance; and a first isolated communication circuit configured to transfer the voltage signal outputted from the voltage-sensing circuit to the controller at a low voltage side that is galvanically isolated from the high voltage side.
