The invention discloses a high-voltage safety protection structure of a battery pack, the battery pack and a vehicle, and belongs to the technical field of new energy vehicles. Comprising a battery pack shell for bearing a battery cell, supporting pieces which are oppositely arranged are arranged in the battery pack shell, an electric device mounting space is formed between the supporting pieces, and a battery cell mounting space is formed between the battery pack shell and the supporting pieces; the height of the supporting piece is higher than that of the upper surface of the battery cell, and the supporting piece is located under the lap joint of the middle channel and the seat rear cross beam so as to bear downward extrusion force generated by the lap joint under the side column collision working condition. The self-protection of the battery pack can be increased in the side column collision working condition without modifying a vehicle body, the contact between the battery pack module or the upper surface of a core body and peripheral parts is reduced, and the high-voltage safety of the battery pack is ensured; the problems that an existing protection means is high in transformation cost and transformation difficulty are solved.
本发明公开了一种电池包高压电安全防护结构、电池包及车辆,属于新能源汽车技术领域。包括用于承载电芯的电池包壳体;所述电池包壳体内部设置有相对设置的支撑件,所述支撑件之间具有电器件的安装空间,所述电池包壳体与所述支撑件之间具有电芯的安装空间;所述支撑件的高度高于所述电芯的上表面,且所述支撑件位于所述中通道与所述座椅后横梁搭接处的正下方,以承接侧面柱碰工况下搭接处向下产生的挤压力。无需对车身进行改造即可在侧面柱碰工况中增加电池包的自我防护,降低电池包模组或芯体上表面与周边件的接触,保证电池包高压电安全;解决现有防护手段改造成本高、改造难度大的问题。
