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 low-temperature environment is better.
本申请提供一种电池包及汽车,涉及电池技术领域。其中,电池包包括框体、底板和电池组。框体设置于底板上,电池组也设置为底板上,且框体围设于底板。底板中的部分可采用拉挤成型复合材料件,使得底板具有较佳的结构强度,从而使得底板可更好地支撑电池组。框体也采用拉挤成型复合材料件,这样底板与框体还具有较佳的保温性能。底板和框体将电池组围设可在一定程度上避免电池组热量散热,从而使得本申请的电池包在低温环境下的性能更佳,进而使得应用本申请的电池包的汽车在低温环境下续航更佳。
