The invention provides an integrated structure of a battery system and an automobile chassis, which comprises a bottom plate frame, a cold pipe joint module and a cold plate, the chassis frame is used as a box body frame beam of the battery system, and the lower end of the box body frame beam is open; a notch is formed in the lower end of a front-end cross beam or a rear-end cross beam of the chassis frame, and the cold pipe connector module is connected to the notch in a sealed mode after being pre-connected with the cold plate. The technical problem that in a traditional scheme, a cooling pipe connector is arranged on the side face of a box body, and enough operation space must be reserved in the battery pack in the side direction during design is mainly solved. The cold pipe joint module and the cold plate are pre-integrated into a whole, so that an operation space does not need to be reserved for connection of the cold pipe and the cold pipe joint in the battery pack, the internal space of a battery system can be saved, multiple battery cells can be arranged, the battery system is compactly arranged, and the energy density of the battery system is improved.

    本发明提供了一种电池系统与汽车底盘的集成结构,包括底板框架、冷管接头模块和冷板,所述底盘框架作为所述电池系统的箱体框梁,该箱体框梁的下端开口;所述底盘框架的前端横梁或后端横梁的下端设有缺口,所述冷管接头模块与所述冷板预连接后密封连接在该缺口上。本发明主要规避了传统方案中冷管接头布置于箱体侧面,设计时电池包内必须侧向预留足够的操作空间的技术问题。本发明将冷管接头模块与冷板预集成为一个整体,那么电池包内就不需要为冷管与冷管接头连接预留操作空间,能够节省电池系统内部空间,用来多布置电芯,电池系统布置紧凑,以提升电池系统能量密度。
