The invention discloses an electric automobile charging pile detection device, which comprises a charging interface used for connecting a charging gun, a storage battery voltage simulation unit, a load interface used for connecting a load and a control unit, and is characterized in that the charging interface comprises a main circuit interface and a communication interface; before charging is started, the control unit controls the storage battery voltage simulation unit to be connected to the main circuit interface and enables the storage battery voltage simulation unit to generate set output voltage at the main circuit interface so as to simulate actual voltage of a storage battery, and the control unit transmits rated voltage of the storage battery to the communication interface; and during charging, the simulated storage battery unit is separated from the main circuit interface, and the load interface is enabled to be connected to the main circuit interface. The electric automobile charging pile detection device can provide various signals of a charging pile required to be detected so as to judge whether the charging pile is normal or not in function, the circuit structure is simple, and a technology of detecting the charging pile by using an entity automobile or actual storage battery system in the prior art is replaced.
