The invention discloses a battery pack, a vehicle chassis and a vehicle, and belongs to the technical field of new energy, and the battery pack comprises a frame body (100) and a battery cell assembly (200) arranged in the frame body (100); the battery cell assembly (200) comprises a plurality of battery cells (210) and a restraining assembly (220) for restraining the plurality of battery cells (210) into groups, the restraining assembly (220) is connected with the frame body (100), and the restraining assembly (220) can transmit the gravity of the battery cells (210) to the frame body (100). According to the battery pack, the gravity of the battery cell (210) is transmitted to the frame body (100) by utilizing the constraint assembly (220), the weight of the battery cell (210) is borne by utilizing the frame body (100), and the bottom plate (400) does not play a supporting role or only plays a weak supporting role, so that the strength requirement on the bottom plate (400) is greatly reduced, the thickness of the bottom plate (400) can be greatly reduced, and the longitudinal size of the battery pack is further reduced.

    本申请公开了一种电池包、车辆底盘及车辆,属于新能源技术领域,其中,电池包包括:框体(100)与设于框体(100)中的电芯组件(200);电芯组件(200)包括多个电芯(210)以及将多个电芯(210)约束成组的约束组件(220),约束组件(220)与框体(100)连接,约束组件(220)能够将电芯(210)的重力传递至框体(100)。该电池包通过利用约束组件(220)将电芯(210)的重力传递至框体(100),利用框体(100)承载电芯(210)的重量,而底板(400)不起支撑作用或仅起到弱支撑作用,此时,对底板(400)的强度要求大大降低,因此底板(400)的厚度可大幅降低,进而缩小了电池包纵向的尺寸。
