The invention relates to the technical field of new energy vehicles, in particular to a battery box assembly which is used for containing a battery pack structure and comprises a cover plate and a composite shell, the cover plate is used for being installed on a vehicle frame, and the battery pack structure is connected to the lower end of the cover plate; the composite material shell is provided with a mounting cavity for accommodating the battery pack structure, and the lower end surface of the cover plate is in sealed connection with an opening of the composite material shell so as to seal the mounting cavity; the upper end of the cover plate is used for being installed on the frame, that is, the cover plate replaces an original bottom plate of the frame, and the overall weight of the vehicle is reduced. The weight of the battery pack structure and the weight of the composite material shell are both borne by the cover plate and are not supported by the composite material shell, the requirement for the strength of the composite material shell is lowered, the material and manufacturing cost is lowered, and the overall weight of the battery box assembly is lowered.
本发明涉及新能源汽车技术领域,具体提供了一种电池盒总成,该电池盒总成用于容纳电池包结构,包括盖板和复合材料壳体,所述盖板用于安装于车架上,所述电池包结构连接于所述盖板的下端;所述复合材料壳体上具有用于容纳所述电池包结构的安装腔,所述盖板的下端面与所述复合材料壳体的开口密封连接以密封所述安装腔;盖板的上端用于安装于车架上,也就是说盖板代替原来的车架的底板,有利于降低车辆整体的重量;电池包结构和复合材料壳体的重量均由盖板承载,不由复合材料壳体支撑,有利于降低对复合材料壳体的强度要求,材料和制造成本降低,也有利于降低电池盒总成的总体重量。
