The invention relates to the technical field of energy storage devices, in particular to a battery module and an electric vehicle. The battery module comprises a plurality of battery cells, a coolingdevice, a first busbar, a second busbar and a heat-conducting insulating part. Each of the battery cells is provided with a first surface and a second surface which are opposite to each other, and positive electrodes and negative electrodes of the battery cells are arranged on the sides of the first surfaces; the cooling device is arranged on the side where the second surfaces are located; the first busbar and the second busbar are arranged on the side where the first surfaces are located, and the positive electrodes and the negative electrodes of the multiple battery cells are connected withthe first busbar and the second busbar correspondingly. The heat-conducting insulating part comprises an upper part, a side part and a bottom part, the upper part and at least one of the first busbarand the second busbar are arranged in a laminated mode, the upper part is connected with the bottom part through the side part, and the bottom part and the cooling device are arranged in a laminated mode. The service life of the battery module provided by the invention is relatively long.
