Electric vehicle
By designing a tapered structure and inclined section for the battery pack, the front and rear wheels are guided to move outward in the vehicle width direction during a collision, thus solving the load problem of the battery pack during a vehicle collision and achieving load reduction and connector protection.

AI Technical Summary
Technical Problem
During a vehicle collision, the battery pack is susceptible to impact loads from the front and rear wheels, and existing technologies struggle to effectively reduce these loads.
Method used
The battery pack is designed with a first and a second cone that are tilted toward the center of the vehicle along its length, forming a first and a second tilted section. This is to guide the front and rear wheels to move outward in the width direction during a collision, reducing the impact on the battery pack.
Benefits of technology
It effectively reduces the load on the battery pack during frontal and rearward collisions, increases battery capacity, and reduces the impact risk to the connectors.

Abstract
Provided is an electric vehicle capable of reducing a load acting on a battery pack in the case where a front wheel or a rear wheel comes into abutment with the battery pack. An electric vehicle (100) is provided with a battery pack (10), a front wheel (41), and a rear wheel (42). The battery pack (10) is provided with two first inclined portions (15, 16) inclined in such a manner that they are located on the outer side in the vehicle width direction as they go toward the rear in the vehicle length direction. The battery pack (10) is provided with two second inclined portions (17, 18) inclined in such a manner that they are located on the outer side in the vehicle width direction as they go toward the front in the vehicle length direction. The first inclined portions (15, 16) are provided at positions that come into abutment with the first inclined portions (15, 16) in the case where the front wheel (41) moves toward the rear in the vehicle length direction. The second inclined portions (17, 18) are provided at positions that come into abutment with the second inclined portions (17, 18) in the case where the rear wheel (42) moves toward the front in the vehicle length direction.
