The invention relates to a battery tray, a battery pack and electric equipment, and the battery tray comprises a tray body which comprises a bottom plate and a plurality of surrounding plates, and the bottom plate and the plurality of surrounding plates jointly form a storage space; the partition assembly comprises longitudinal beams extending in the first direction, cross beams extending in the second direction and blocking pieces, at least one of the longitudinal beams and the cross beams is at least two, and the longitudinal beams and the cross beams are arranged in a crossed mode and are connected with the tray body in a sealed mode; blocking pieces are correspondingly arranged at the intersections of the longitudinal beams and the cross beams, the blocking pieces abut against the longitudinal beams and the cross beams, and the containing space is divided into a plurality of subspaces by the blocking pieces, the longitudinal beams and the cross beams together. The longitudinal beams are provided with first airflow channels, the first airflow channels communicate with the corresponding subspaces, and the blocking pieces are used for blocking the multiple subspaces located on the two sides of the longitudinal beams and the two sides of the cross beams. According to the technical scheme, the battery tray can effectively inhibit gas generated by thermal runaway of a certain battery cell group from inducing thermal diffusion among different battery cell groups.

    本公开涉及一种电池托盘、电池包和用电设备,该电池托盘包括:托盘本体,包括底板和多个围板,底板与多个围板共同形成收纳空间;分隔组件,包括沿第一方向延伸的纵梁和沿第二方向延伸的横梁以及阻隔件,纵梁与横梁中至少一者为至少两个,纵梁和横梁相交布置并且分别与托盘本体密封连接;纵梁与横梁的交汇处对应布置有阻隔件,阻隔件与纵梁和横梁抵接,并且阻隔件、纵梁与横梁共同将收纳空间分隔为多个子空间;纵梁设置有第一气流通道,第一气流通道与对应的子空间连通,阻隔件用于阻隔位于纵梁的两侧和横梁的两侧的多个子空间。通过上述技术方案,电池托盘能够有效抑制因某一电芯组发生热失控而产生的气体诱发不同电芯组之间的热扩散。
