According to the integrated battery assembly, a lower box body assembly and a vehicle body chassis are integrated, and a containing cavity is formed in the lower box side wall of the lower box body assembly in a surrounding mode; the battery module is arranged in the accommodating cavity of the lower box body assembly; the integrated controller is arranged in the accommodating cavity of the lower box body assembly; the battery management system collects data signals of the battery module in a wireless communication mode, exchanges data with the integrated controller in the wireless communication mode, and is arranged above the battery module; the battery upper box body is arranged at the upper part of the battery module and lower box body assembly; a gap area between the lower box body assembly and the upper box body assembly is filled with cooling liquid, and the upper box body is fixedly connected with the lower box body assembly through a sealing face. The integration level of the electric vehicle is obviously improved; the battery cooling effect is obviously improved, and the battery safety performance is obviously improved; the number of battery parts is obviously reduced, the weight is reduced, and the energy consumption is reduced.
