The invention discloses a battery pack protection structure and a battery pack, and belongs to the technical field of batteries. The battery pack protection structure comprises a supporting structurewhich is connected to the inner side of a battery shell, wherein a first air hole is formed at the position, corresponding to an explosion-proof valve or a waterproof breathable film on the battery shell and the supporting structure; a humidity adjusting plate and a pressing structure, wherein the pressing structure is used for pressing the humidity adjusting plate on the supporting structure, second air holes are formed in the pressing structure, and the humidity adjusting plate is configured to absorb the water vapor in air entering the battery pack when the relative humidity of the workingenvironment where the battery pack is located is larger than or equal to the preset humidity. According to the battery pack protection structure provided by the embodiment of the invention, by arranging the humidity adjusting plate, the condensed water generated by the condensation of the water vapor in the battery pack is avoided, so that the situation of the short circuit of the high-voltage andlow-voltage circuits in the battery pack caused by the condensed water is avoided, and the safety performance of the battery pack is improved.

    本发明公开了一种电池包防护结构及电池包,属于电池技术领域,包括支撑结构,连接于电池壳体内侧,且支撑结构与电池壳体上的防爆阀或防水透气膜对应的位置开设有第一透气孔;调湿板和压紧结构,压紧结构用于将调湿板压紧于支撑结构,压紧结构上开设有第二透气孔,调湿板被配置为能够在电池包所处的工作环境的相对湿度大于等于预设湿度时,吸收进入到电池包内的空气中的水蒸气。本实施例提供的电池包防护结构,通过设置调湿板,避免水蒸气在电池包内冷凝而产生冷凝水,从而避免冷凝水导致电池包内高低压线路短路情况的出现,提高电池包的安全性能。
