The invention provides a conveying and operating platform, a battery replacement station and a conveying and operating method. The conveying and operating platform comprises multiple sub-platforms andconveying mechanisms. The conveying mechanisms and the multiple sub-platforms are arranged in a related manner so that to-be-operated workpieces can be conveyed between at least two sub-platforms. The conveying and operating platform, the battery replacement station and the conveying and operating method have the beneficial effects that the workpieces, especially power batteries, can be efficiently conveyed and operated; and particularly, the workpieces can be synchronously conveyed between all the sub-platforms in parallel, and the stable lifting design capable of being easily achieved is achieved.
