A fuel cell-supercapacitor hybrid system for unmanned vehicles

Abstract

The invention discloses a fuel cell-supercapacitor hybrid power system for an unmanned vehicle, comprising a data acquisition module, a vehicle positioning module, a data calculation module, a data processing module, an energy management module, a fuel cell, a supercapacitor and a Drive motor; the data acquisition module is used to collect the real-time parameters and attribute parameters of the vehicle. The on-board positioning module is equipped with map software to output the parameters of the vehicle's driving path and the time required for driving; the data processing module is used to calculate the current power consumption and correct it. Power Point Lookup Table. The system calculates the vehicle's required power in advance by setting the vehicle's driving intention combined with the map software, which is conducive to the early intervention and allocation of the fuel cell and super capacitor by the energy management module, ensuring that the real-time output demand power of the vehicle is satisfied during the driving distance, and realizing fuel consumption The dynamic optimal distribution of batteries and supercapacitors makes the output power of both fuel cells and supercapacitors fall within their respective high-efficiency regions.

Description

technical field [0001] The invention relates to the technical field of a fuel cell-supercapacitor hybrid power system for vehicles, in particular to a fuel cell-supercapacitor hybrid power system for an unmanned vehicle. Background technique [0002] The matching development of fuel cell-related power systems has always been an important part of the development process of fuel cell vehicles. Due to the limitation of loading and unloading of the fuel cell system itself, it is necessary to select an appropriate matching power source. [0003] Existing fuel cell vehicles generally use a fuel cell-power cell hybrid power system, or a fuel cell-power cell-supercapacitor hybrid power system, both of which are used in manned fuel cell vehicles. However, the driverless car cannot obtain the driver's operation intention, and it is difficult to accurately obtain the required power of the vehicle, which leads to the problem that the vehicle cannot output the required power in real tim...
