The invention relates to the technical field of vehicle charging, particularly provides an automatic switching circuit, a vehicle-to-vehicle charging control method, a control device and a storage medium, and aims to solve the problems of how to realize normal starting, fault protection and log recording of a vehicle-to-vehicle charging control panel and avoid continuous discharging. In order to achieve the purpose, competitive power supply of an external direct-current converter power supply and an external power supply battery is achieved through a competitive power supply module, a voltage detection module detects the voltage of the external direct-current converter power supply, and the access condition of the external power supply battery is controlled according to the detection result; the control module controls the automatic switching circuit according to the access condition of the external power supply battery, and the signal isolation module isolates the control module from other modules of the automatic switching circuit, so that automatic switching control of the external DC converter power supply and the external power supply battery can be realized. The power supply condition of an external DC converter power supply can be monitored in real time, and automatic switching of an external power supply battery under the abnormal power failure condition is realized.
