Geographic position information based energy management method and system of fuel cell vehicle

Abstract

The invention relates to a geographic position information based energy management method and system of a fuel cell vehicle. The method comprises the following steps: acquiring state information of each part of a power system of the fuel cell vehicle and the vehicle location data through a vehicle controller; sending the data to a cloud server; calculating and generating a multi-dimensional energymanagement strategy MAP through the cloud server based on the data; and adjusting the output power of fuel cells in the fuel cell vehicle through the vehicle controller based on the multi-dimensionalenergy management strategy map. Therefore, the calculation capacity of the vehicle controller is saved, and the cost is decreased; in addition, the cloud storage of the vehicle running data is achieved; the vehicle control strategy can be automatically upgraded; the output power of the fuel cells can be automatically adjusted in the actual running process of the fuel cell vehicle; the cell resource of the fuel cell vehicle is reasonably distributed; and the running strategy is optimized.

Description

technical field [0001] This application relates to the field of fuel cell research, in particular to a fuel cell vehicle energy management method and system based on geographic location information. Background technique [0002] With the sharp increase in global environmental pressure, new exhaust emission regulations and vehicle fuel consumption regulations are continuously introduced. New energy vehicles are increasingly favored by people because of their advantages such as low pollution and low emissions. Fuel cell vehicles are a type of new energy vehicles. The energy of the fuel cell vehicle battery is generated through the chemical action of hydrogen and oxygen, rather than directly converted into electricity through the combustion of energy gas. The chemical reaction process of the fuel cell does not produce harmful products, and the product is only water, which does not pollute the environment, making fuel cell vehicles have great market advantages. In addition, t...
