The invention discloses a quick-plug connecting device, an electric vehicle and a battery rack, the quick-plug connecting device is used for being connected with a battery pack so as to convey a cooling liquid into a liquid cooling pipeline in the battery pack, and the quick-plug connecting device comprises a fixing plate, a connecting plate and a connecting rod, the floating mechanism is elastically connected to the fixed plate; and the liquid cooling connector is connected to the floating mechanism and used for being connected with the liquid cooling pipeline in an inserted mode. The liquid cooling connector is connected to the floating mechanism, the floating mechanism is elastically connected to the fixed plate, and the liquid cooling connector is in floating connection through the floating mechanism, so that a liquid cooling pipeline of the battery pack and the liquid cooling connector can be butted even if a certain deviation exists between the liquid cooling pipeline and the liquid cooling connector; according to the quick-plug connecting device, the success rate of plug-in connection between the liquid cooling connector and the liquid cooling pipeline in the battery pack is improved, meanwhile, no leakage phenomenon exists in the plug-in connection process, connection looseness of the liquid cooling connector is effectively avoided, the stability of the quick-plug connecting device is greatly improved, and the service life of the quick-plug connecting device is prolonged.
