An integrated battery-to-vehicle-body structure and an electric vehicle are provided. The integrated battery-to-vehicle-body structure includes a vehicle body frame and a battery pack. The vehicle body frame has two rockers that are disposed in parallel and an accommodation space that is located between the two rockers. The battery pack includes an enclosure and a battery cell component and a crossbeam that are disposed inside the enclosure. The crossbeam is connected to the enclosure. After the electric vehicle is assembled as a whole, the enclosure is installed on the rockers, a top part of the enclosure can serve as a vehicle body floor, to simplify a vehicle body structure and reduce a weight of the electric vehicle. In addition, the battery pack being located in the accommodation space, without changing an overall vehicle size, can allow an increased volume of the battery pack, thereby increasing a capacity of the battery pack and improving overall range performance. When a rocker is deformed due to exerted force, the crossbeam presses against and supports the rocker, to prevent the rocker from crushing the battery cell component due to excessive deformation, thereby improving torsional stiffness and bearable longitudinal load of the integrated battery-to-vehicle-body structure and improving security of the electric vehicle.
