The invention relates to a switching circuit and a vehicle. The switching circuit comprises a current detection module, a control module and a switching module, the first end of the switch module is electrically connected with the power input end; the second end of the switch module is electrically connected with the first end of the current detection module; the third end of the switch module is electrically connected with the output end of the control module; the second end of the current detection module is electrically connected with the power supply output end, and the output end of the current detection module is electrically connected with the control enabling end of the control module; the current detection module comprises a detection resistor; the current detection module outputs a first effective enable signal to the control enable end of the control module when the current of the power supply input end meets a first fault condition; the control enabling end of the control module is connected with a first effective enabling signal, the output end of the control module controls the switch module to be disconnected, and the power input end and the power output end are disconnected. According to the technical scheme, the precision and accuracy of current detection are improved, and the safety of the vehicle is improved.
