Energy management method for three-energy-source new energy automobile and electronic equipment

Abstract

The invention provides an energy management method for a three-energy-source new energy automobile and electronic equipment. The method comprises the following steps: acquiring the feedback power of the whole automobile and the power of a motor, controlling the output power of a fuel cell; when the feedback power of the whole automobile reaches a certain value, outputting idle speed power by the fuel cell; when the whole vehicle feedback power is lower than a certain value, acquiring the SOC value of the power battery; determining a first fuel battery power corresponding to the SOC value of the power battery according to the SOC value of the power battery; when the opening degree of an accelerator pedal is within the threshold range, outputting a second fuel battery power corresponding to the opening degree of the accelerator pedal; determining a maximum value between the first fuel cell power and the second fuel cell power as a fuel cell output power; and controlling the output power of a super capacitor, wherein the difference between the motor power and the output power of the fuel cell and the output power of the super capacitor is the power of the power cell. By reasonably adjusting the energy flow and power among the three energy sources, the output power smoothness of the hydrogen fuel cell is improved, and the service life of the hydrogen fuel cell is effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of battery energy control of new energy vehicles, and in particular relates to an energy management method and electronic equipment for new energy vehicles with three energy sources. Background technique [0002] With the formulation of the national goal of "carbon peaking and carbon neutrality", the research on the application of new energy in various industries is becoming more and more extensive and in-depth. As an important energy consumption carrier, automobiles are no exception. At present, the new energy sources used in automobiles mainly include power batteries, hydrogen fuel cells, and supercapacitors. Due to the slow dynamic response, the inability to recycle energy, and the low energy density of supercapacitors, it is difficult for a single energy source to meet the power and economy requirements of automobiles. Therefore, the combined use of the above-mentioned new energy sources has become an in...

At present, the new energy sources used in automobiles mainly include power batteries, hydrogen fuel cells, and supercapacitors. Due to slow dynamic response, inability to recover energy, and low energy density of supercapacitors, it is difficult for a single energy source to meet the power and economy requirements of automobiles, so the combined use of the above-mentioned new energy sources has become an inevitable choice.
