Title:
BATTERY MODULE, BATTERY PACK, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/052006
Kind Code:
A1
Abstract:
The present application provides a battery module, a battery pack, and a vehicle. The battery module comprises a battery, a first end plate, and a second end plate. A first protruding portion of the first end plate is provided with a first installation hole. A second protruding portion of the second end plate is provided with a second installation hole. A lower surface area of the first protruding portion is S1, a distance from a center axis line of the first installation hole to a center line of the battery module is d1, a lower surface area of the second protruding portion is S2, a distance from a center axis line of the second installation hole to the center line of the battery module is d2, d1 > d2, and S1 < S2. Since d1 > d2, the invention achieves fitted assembly of battery modules, and ensures the equilibrium of forces between different fastening points by enabling a force F1 applied at a fastening point corresponding to the first installation hole to be less than a force F2 applied at a fastening point corresponding to the second installation hole. Since F1 < F2 and S1 < S2, a difference between P1 and P2 is reduced, thereby preventing over-engineering of the structural strength of the first protruding portion or the second protruding portion, increasing the energy density of the battery pack accordingly, and ensuring fastening reliability between the battery module and an enclosure.
