Conduction charging test system for electric vehicle

The invention provides a conduction charging test system for an electric vehicle. The system comprises a vehicle control simulation device, a battery simulation device and a controller. The vehicle control simulation device is used for being connected with a to-be-tested charging device to respectively output a signal set of each contact, wherein the signal set of the contact comprises a voltage and/or current information set. The vehicle control simulation device comprises a vehicle simulation circuit and a variable resistor is arranged between a detection point and a protective earthing point of the vehicle simulation circuit. The battery simulation device is connected with the vehicle control simulation device and outputs a simulation battery state signal. The controller is respectively connected with the vehicle control simulation device and the battery simulation device and is used for receiving the signal set of each contact and the simulation battery state signal and then analyzing the signal set of th
