Abstract
A detection device, and a method for inspecting a relay, and a charging pile are provided. The detection device includes a detection module and an isolation output module. The detection module includes a first signal input terminal for connecting to an output side of a relay and a second signal input terminal for connecting to a neutral wire. A signal output terminal of the detection module is configured to connect to a control end of the isolation output module. The detection module is configured to output a control signal based on an on-off state of the relay. A signal output terminal of the isolation output module is configured to connect to a fault identification device. The isolation output module is configured to output a to detection signal with a duty cycle corresponding to the control signal, to inform the fault identification device to detect whether the relay is stuck.
