The invention relates to a fuel cell power system hierarchical coordination control method and system. The fuel cell power system hierarchical coordination control method comprises the following stepsthat on one hand, the required power of the whole vehicle after the preset time period and the component state information under the current time node are acquired; in order to meet the required power of the whole vehicle, the fuel cell system needs to adjust parameters, so that the fuel cell system can dynamically follow the required power of the whole vehicle, the internal state of the fuel cell system is uniform, and the air compressor does not generate an air shortage phenomenon; and on the other hand, charging and discharging actions which should be adopted by the power battery are determined according to the whole vehicle required power and the component state information, so that the state-of-charge value of the power battery is kept in a reasonable interval, the charging and discharging times of the power battery are reduced as much as possible, the whole vehicle required power is achieved under the condition that the electric energy transduction efficiency of the power battery is not influenced, and extra power consumption is not increased.
Description
technical field [0001] The present application relates to the technical field of fuel cell vehicles, in particular to a method and system for layered coordinated control of a fuel cell power system. Background technique [0002] With the rapid development of human society, the demand for energy is expanding day by day, and the environmental pollution is becoming more and more serious. Compared with traditional internal combustion engines, fuel cells have the characteristics of high efficiency, low noise, and no pollution. They have attracted more and more attention from governments and car companies in various countries, and research on fuel cell vehicles has become more and more frequent. A fuel cell vehicle is driven by a fuel cell power system. In a fuel cell power system, there are generally two power sources, namely a fuel cell and a power battery. The power battery is the accumulator. The fuel cell is connected to the DC / DC converter, the DC / DC converter is connecte...
