The present invention provides a high-voltage detection circuit, detector, battery device and vehicle, the high-voltage detection circuit includes: a controller including a first signal input port, a second signal input port, and a signal output port; a current detection sub-circuit for sampling a current signal of internal side of a main negative switch and for transmitting the current signal to the first signal input port; a switch detection sub-circuit, a first end of the switch detection sub-circuit being configured to sample a first electric signal of external side of a to-be-detected switch, and a second end of the switch detection sub-circuit being configured to transmit the first electric signal to the second signal input port; and a switch driving sub-circuit, configured for sampling a switch control signal via the signal output port and generating a switch driving signal according to the switch control signal. With the technical solutions of the present invention, at least the transmission distance of the first electric signal of the external side of the to-be-detected switch and the switch control signal can be shortened, and energy loss during the transmission of the first electric signal of the external side of the to-be-detected switch and the switch control signal can be decreased, so that the detection result of the switch detection sub-circuit and the control of the switch driving sub-circuit with respect to the to-be-controlled switch are more accurate.
