Battery, chassis and vehicle

The utility model is applicable to the technical field of power batteries, and provides a battery, a chassis and a vehicle. The box body comprises a lower box body and an upper box body covering the lower box body, and the upper box body and the lower box body define an accommodating cavity for accommodating the battery monomers; in the height direction of the box body, at least part of the energy absorption assembly is arranged on the side, away from the containing cavity, of the lower box body; according to the battery provided by the embodiment of the invention, the first energy absorption structure is arranged on the peripheral side of the lower box body, the energy absorption assembly is arranged on the bottom surface of the lower box body, and the energy absorption assembly is connected with the first energy absorption structure, so that collision energy borne by the battery is absorbed through the first energy absorption structure and the energy absorption assembly, and the effect of protecting the battery is achieved; the energy absorption assembly located at the bottom of the box body can also play a role in protecting the bottom of the box body, so that possible damage to the battery due to the fact that sundries such as splashed broken stones and road protrusions directly collide with the battery in the running process of the vehicle is reduced.
