Power generation device of new-energy vehicle and method thereof

Abstract

The invention discloses a power generation device of a new-energy vehicle. The power generation device of the new-energy vehicle comprises a cylindrical inner shell. An inner cavity of the inner shellis a tail gas energy-converting cavity. A rotating impeller is coaxially arranged in the tail gas energy-converting cavity. The rotating impeller is of a ring body cylindrical structure coaxial withthe tail gas energy-converting cavity. A smoke heat exchange channel is formed between the rotating impeller and the inner wall of the inner shell. The rotating impeller sequentially comprises a leftring body, a middle ring body and a right ring body in the axial direction, wherein the left ring body, the middle ring body and the right ring body are connected in an integrated manner. The power generation device of the new-energy vehicle is simple in structure, in the process that air sequentially passes through a left ring cavity, a middle ring cavity and a right ring cavity, a large amount of heat released by high-temperature tail gas in the inner shell is absorbed by the air flowing in the left ring cavity, the middle ring cavity and the right ring cavity, and then the effect of preheating the air which is about to enter an intake valve of an engine is achieved.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, in particular to a power generation device and a method for the new energy vehicles. Background technique [0002] Compared with traditional internal combustion locomotives, electric new energy vehicles have the advantages of good acceleration performance, quietness and smoothness, and no pollution emissions; however, the power battery on new energy vehicles is limited, so electric new energy vehicles have poor endurance compared with traditional internal combustion locomotives; and Portable internal combustion engine generators can be used as a backup power source for electric new energy vehicles when the battery is exhausted; the exhaust of existing internal combustion engine generators actually contains a large amount of impact kinetic energy and heat energy, and if it is discharged directly, it will cause energy loss.
