The invention discloses a battery pack and a vehicle with the same. The battery pack comprises a shell, a battery pack and a battery pack, the battery pack is arranged in the shell, the battery pack comprises a plurality of battery cells, and the plurality of battery cells are arranged in the thickness direction of the battery cells; the temperature control anti-collision assemblies are arranged in the shell and comprise air bags, the number of the temperature control anti-collision assemblies is multiple, the air bags are arranged on the two sides of each battery cell in the thickness direction, and the battery cells are attached to the air bags; and the air channel conveying assembly is arranged in the shell and communicates with the air bag. According to the battery pack disclosed by the invention, the air bags are arranged on the two sides of each battery cell in the thickness direction, so that on one hand, the battery cells can be fixed to play a role in shock absorption and collision prevention, and on the other hand, certain pressure can be generated on the surfaces of the battery cells adjacent to the air bags to avoid incomplete charging and discharging. Moreover, by controlling the temperature of the air filled into the air bag, the influence of too low or too high temperature on the performance of the battery pack can be avoided, and the cycle life and the endurance mileage of the battery pack are guaranteed.

    本发明公开了一种电池包和具有其的车辆,电池包包括:壳体;电池组,电池组设于壳体内,电池组包括多个电芯,多个电芯在电芯的厚度方向上排布;温控防撞组件,温控防撞组件设于壳体内且包括气囊,温控防撞组件为多个,每个电芯厚度方向的两侧均设有气囊,电芯与气囊贴合;气路输送组件,气路输送组件设于壳体内且与气囊连通。根据本发明的电池包,通过在每个电芯厚度方向的两侧设有气囊,一方面可以对电芯进行固定,起到减震防撞的作用,另一方面能够对与气囊相邻的电芯的表面产生一定的压力,避免充放电不完全的情况。并且,通过控制充入气囊内的空气的温度,能够避免因温度过低或过高对电池包的性能造成影响,保障电池包的循环寿命及续航里程。
