Abstract: The disclosure relates to the technical field of traction batteries, and in particular to a battery pack and a vehicle comprising the battery pack. The invention aims at the problem of large heat loss in the existing traction battery in a low-temperature environment. To this end, the battery pack of the disclosure comprises: a frame internally formed with an installation site; a battery module mounted in the installation site and comprising a number of cells; and a side beam connected to an outer side wall of the frame and made of a first thermal insulation material. The above arrangement can reduce the heat transfer coefficient of natural convection between the side wall of the frame and the environment, and reduce the heat flux, thereby reducing the temperature loss of the cells.
