Charging gun emergency release device and electric vehicle charging test system

The invention provides a charging gun emergency release device and an electric vehicle charging test system, and relates to the field of electric vehicle test. The charging plug unlocking wrench is arranged to achieve buckle unlocking, and when unlocking needs to be carried out, the cylinder head of the air cylinder is pressed downwards, and the wrench lock head is lifted up to leave the buckle groove; separation control is achieved by arranging the charging gun separation device, when separation needs to be carried out, a cylinder body of a double-shaft air cylinder is controlled to work to push a shaft head of the double-shaft air cylinder, thrust is transmitted to a push plate to generate counter-acting force, and the device is separated from a charging port of the electric vehicle; in addition, when separation is not needed, popping-up energy charging is carried out firstly to prepare for stress accumulation, and when emergency separation is carried out, the charging plug can be directly unlocked and popp
