The invention discloses an insulation detection auxiliary system of an electric automobile and the electric automobile. The insulation detection auxiliary system of the electric automobile comprises a plurality of connection interfaces, the plurality of connection interfaces are connected with the plurality of high-voltage electric appliance loops in a one-to-one correspondence mode, and the plurality of high-voltage electric appliances are connected with the plurality of high-voltage electric appliance loops in a one-to-one correspondence mode through a plurality of high-voltage plugs; and the maintenance interface is respectively connected with the plurality of connection interfaces, the maintenance interface can be selectively switched on and switched off, and when the maintenance interface is switched on, the high-voltage plug of each high-voltage electric appliance is sequentially switched off so as to detect a high-voltage electric appliance loop with an insulation fault. By adopting the method, the time for troubleshooting the insulation fault can be effectively saved, the position of the insulation fault can be preliminarily judged without an insulation meter, the method has the advantages of simplicity and convenience in troubleshooting, the short-distance driving function of the vehicle can be ensured after the insulation fault of the vehicle occurs, and the method has higher convenience.
