Abstract

The invention discloses an electric pile injection system of a new energy automobile. The electric pile injection system comprises a high-pressure hydrogen source and an electric pile, and hydrogen of the high-pressure hydrogen source enters the electric pile to generate a chemical reaction. The electric pile injection system is characterized by further comprising a backflow device and a voltage stabilizer; the backflow device comprises a back voltage device, a water-gas separation device and an ejector, a first inlet of the ejector is connected with the high-pressure hydrogen source, a second inlet of the ejector is connected with the water-gas separation device, and an ejection outlet of the ejector is connected with the high-pressure hydrogen source through the voltage stabilizer; and the residual hydrogen in the electric pile is ejected back into the electric pile through the back voltage device and the water-gas separation device. An expansion tank is arranged on the front side of the electric pile, and when the system increases front air pressure or ensures the adsorption air pressure, normal work of the airflow ejector is not influenced under the severe working condition.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, and more specifically relates to a stack injection system for new energy vehicles. Background technique [0002] As the concept of green and environmentally friendly life is gradually becoming popular, more and more people are choosing new energy vehicles, especially hydrogen engine vehicles. Since the fuel used by hydrogen engines is gaseous hydrogen, the emissions are pure water, which has infinite Pollution, zero emission, rich reserves and other advantages, hydrogen engine vehicles are a means of transportation that truly achieves zero emissions. For example, the Chinese invention patent CN202011502442.8 discloses a fuel cell anode hydrogen circulation system and its control method. The fuel cell anode hydrogen circulation system with a pressure device of the invention includes a hydrogen tank, an ejector, a fuel cell and a buffer tank , the hydrogen tank, ejector, fuel cell and ...
