According to the battery module 100 for a vehicle of the embodiment of the present invention, the proportional relationship between the thickness of the chamber and the height of the case 21 satisfies 0.05 < T1/T2 < 0.5, so that a plurality of pole groups 23 may be arranged in one case 21 even though a plurality of pole groups 23 may be assembled into the case 21 having multiple chambers, the number of cases 21 is reduced, and the gaps between adjacent pole groups 23 are made smaller, so that the space occupation of the components of the battery module 100 except for the case 21 is smaller, so that there are more pole groups 23 in the battery module 100, and the energy density of the battery module 100 is improved.
The thickness of the chamber is the distance between two side walls of the same chamber, which are opposite in the front-rear direction of the battery module 100, and the direction in which the height of the case 21 is located coincides with the direction in which the height of the vehicle is located.
