The invention discloses a battery box and an electric vehicle. The battery box comprises a box shell, a longitudinal supporting beam, a plurality of supporting plates, a plurality of battery modules, a condensation pipeline assembly and a cover body, a cavity and an opening communicated with the cavity are formed in the box shell. The longitudinal supporting beam is arranged in the cavity and located on one side of the opening, and the two ends of the longitudinal supporting beam are connected to the inner wall of the box shell respectively. All the supporting plates are arranged in the cavity. The condensation pipeline assembly is arranged in the cavity, and the battery modules are connected in series by the condensation pipeline assembly. The cover body is connected to the box shell and used for closing or opening the opening. And a plurality of different parts of the cable and the condensation pipeline assembly are limited on the supporting plate. According to the battery box disclosed by the invention, the longitudinal supporting beam is arranged on the inner wall of the box shell on one side of the opening, and the two ends of the longitudinal supporting beam are respectively supported on the inner wall of the box shell, so that a supporting effect on the box shell is achieved, the box shell is prevented from being bent and deformed due to too large weight of the battery module, and the structural stability of the battery box is improved.

本申请公开一种电池箱及电动车辆，电池箱包括：箱壳、纵向支撑梁、多个支撑板、多个电池模组、冷凝管道组件和盖体。箱壳内具有空腔和连通空腔的开口。纵向支撑梁设置于空腔，且纵向支撑梁位于开口一侧，纵向支撑梁两端分别连接于箱壳的内壁。各支撑板均设置于空腔内。冷凝管道组件设置于空腔内，且冷凝管道组件将各电池模组串连。盖体连接于箱壳，盖体用于封闭或打开开口。其中，线缆和冷凝管道组件均多个不同部位限位于支撑板。本申请的电池箱在开口一侧所述箱壳的内壁上设置了纵向支撑梁，纵向支撑梁的两端分别支撑于所述箱壳的内壁，对箱壳起到了支撑的作用，防止了电池模组的重量太大使箱壳弯曲变形，提升了电池箱的结构稳定性。
