The invention relates to the field of electric vehicle charging and battery replacing, in particular to an electric vehicle battery replacing device and a battery replacing station. The electric vehicle battery replacing device comprises a battery bin, a battery box and a pulley block, the battery bin is arranged at the bottom of an electric vehicle, the pulley block is installed on the side face of the battery bin, and the battery box is hung below the pulley block; a pulley rope is tightened through transmission of the pulley block, and when the battery box ascends in place to be attached to the battery bin, the battery box and the battery bin are tensioned and locked together through tensioning force of the pulley rope. The device has the beneficial effects that when the battery box is moved to the bottom of the vehicle, the battery box does not need to be accurately aligned with the battery bin, the pulley rope can be pulled obliquely to lift the battery box, and when the pulley rope is tightened to enable the battery box to be in a suspended state, the battery box can be automatically straightened and aligned with the battery bin above, the battery replacement process is simplified, and the battery replacement equipment investment of a battery replacement station is reduced.

    本发明涉及电动车充换电领域,特别涉及一种电动汽车换电装置及换电站。电动汽车换电装置包括电池仓、电池箱、滑轮组,所述电池仓位于电动汽车底部,所述滑轮组安装于电池仓侧面,由滑轮组下方吊挂电池箱;通过滑轮组的传动收紧滑轮绳,当电池箱上升到位与电池仓贴合时,靠滑轮绳的张紧力使电池箱与电池仓拉紧并锁止在一起。有益效果是:电池箱移入车底时,无须电池箱与电池仓相互精确对准,滑轮绳可斜拉起吊电池箱,当收紧滑轮绳使电池箱处在悬吊状态时,重力作用会使电池箱自动摆正并对准上方的电池仓,简化了换电过程,减少了换电站的换电设备投资。
