The embodiment of the invention provides a battery pack box body, a battery cell integrated vehicle body and an electric vehicle. The battery pack box body comprises a shell, an upper cover and a reinforcing structure, the shell comprises a bottom shell and an enclosure frame, and the enclosure frame is fixed on the bottom shell and protrudes out of the bottom shell to form a space for accommodating the battery cell; the reinforcing structure comprises at least one longitudinal beam and a plurality of cross beam supports. Each longitudinal beam is fixed to the enclosure frame in the length direction of the electric automobile. Any cross beam bracket is fixed between one longitudinal beam and the enclosure frame or between any two adjacent longitudinal beams in the width direction of the electric vehicle; the beam support is arched and protrudes in the direction away from the bottom shell. The upper cover is fixed to the top, away from the bottom shell, of the enclosure frame in a sealed mode, fixedly connected with the cross beam support and used for forming at least one part of a floor of the frame. The battery pack box body can be integrated with a frame, and the top of the battery pack box body can form at least one part of a frame bottom plate and provide enough treading rigidity, so that the strength requirement of the frame is met.
