The invention provides a battery pack protection device and an electric vehicle with the battery pack protection device. The battery pack protection device comprises an installation base and an energy absorption connecting assembly. The installation base is fixedly arranged on an installation frame for installing a battery pack, and the energy absorption connecting assembly is mounted on the installation base and comprises an energy absorption mechanism and a connecting mechanism; the connecting mechanism is used for connecting the energy absorption mechanism and a positioning body; and the connecting mechanism is affected by the external force effect to move relative to the energy absorption mechanism so as to absorb energy generated by the external force effect. According to the battery pack protection device and the electric vehicle with the battery pack protection device, the battery pack is effectively protected, and the safety performance of the battery pack in the collision process of the electric vehicle is improved.
