Abstract
The present disclosure provides a retention circuit diagnostic system. The retention circuit diagnostic system includes a first retention circuit configured to output a retention signal for controlling a contactor, and a controller configured to transmit a first signal related to a state control of the contactor, and to transmit a second signal for activating the first retention circuit, and configured to diagnose the first retention circuit based on the retention signal.
Claims20
A retention circuit diagnostic system comprising:
- a first retention circuit configured to output a retention signal for controlling a contactor;
- and
- a controller configured to transmit a first signal related to a state control of the contactor, and to transmit a second signal for activating the first retention circuit, and configured to diagnose the first retention circuit based on the retention signal.
A retention circuit diagnostic system comprising:
- a first retention circuit configured to output a first retention signal for controlling a first contactor;
- a second retention circuit configured to output a second retention signal for controlling a second contactor;
- and
- a controller configured to generate a test signal for testing each of the first retention circuit and the second retention circuit, and configured to diagnose at least one of the first retention circuit or the second retention circuit based on at least one of the first retention signal or the second retention signal.
A diagnosis method of a retention circuit, the diagnosis method comprising:
- transmitting a first signal related to a state control of a contactor, and a second signal for activating the retention circuit, to the retention circuit;
- obtaining a retention signal output from the retention circuit;
- and
- diagnosing whether the retention circuit performs a normal operation based on the retention signal.
