The invention provides a battery pack and an automobile, and relates to the technical field of batteries. The battery pack comprises a frame body, a bottom plate and a battery pack, the frame body is arranged on the bottom plate, the battery pack is also arranged on the bottom plate, and the frame body is arranged on the bottom plate in a surrounding mode. Part of the bottom plate can be made of pultrusion composite material pieces, so that the bottom plate has better structural strength, and the battery pack can be better supported by the bottom plate. And the frame body also adopts a pultrusion composite material piece, so that the bottom plate and the frame body also have better thermal insulation performance. The battery pack is surrounded by the bottom plate and the frame body, so that heat dissipation of the battery pack can be avoided to a certain extent, the performance of the battery pack in a low-temperature environment is better, and the endurance of an automobile applying the battery pack in the l
