The invention relates to the technical field of battery replacement, in particular to a vacuum battery replacing device and an electric automobile. The vacuum battery replacing device comprises a vacuum assembly and an air interchanger. The vacuum assembly comprises an upper shell, a lower shell, a pressure sensing device, an air connecting device and a sealing piece; the upper shell is arranged at the top of the lower shell; the lower shell is provided with a vacuum cavity, the vacuum cavity is used for forming a vacuum state inside, the pressure sensing device is communicated with the vacuumcavity through the upper shell, the air connecting device is communicated with the vacuum cavity through the upper shell, and the sealing piece is used for sealing the upper shell and the lower shell. And the air interchanger is used for exhausting or inflating the vacuum cavity. A positioning device ensures the reliability of battery fixing in the vehicle driving process, a battery pack is replaced in a vacuum mode, the replacement time of the battery pack is effectively shortened, the operation is simple, and the cost is reduced.
