Power assembly for electric automobile

The invention provides a power assembly for an electric automobile, and belongs to the technical field of machinery. The power assembly solves the technical problems existing in the prior electric automobile that the position of the original engine room is greatly changed, and new parts need to be developed, so that the design and manufacturing costs are greatly increased and the like. The power assembly comprises a driving motor, a water pump and an air-conditioning compressor, wherein the driving motor is powered by a power battery. The power assembly is characterized in that: a transmission device is arranged between the water pump and the air-conditioning compressor and the driving motor. The driving motor drives the water pump and the air-conditioning compressor by the transmission device, so that the whole structure of the assembly is compact, and the model and accessories of the original oil-powered automobile are not changed, so that the driving habits of wide automobile users are adapted, and the re-development of the DC/DC converter, the electric water pump, the electric air-conditioning compressor and the like is avoided so as to greatly shorten the development period and save cost.
