Fuel cell-super capacitor hybrid power system for unmanned vehicle

Abstract

The invention discloses a fuel cell-super capacitor hybrid power system for an unmanned vehicle. The fuel cell-super capacitor hybrid power system comprises a data acquisition module, a vehicle-mounted positioning module, a data calculation module, a data processing module, an energy management module, a fuel cell, a super capacitor and a driving motor, the data acquisition module is used for acquiring vehicle real-time parameters and attribute parameters, and the vehicle-mounted positioning module carries map software and outputs vehicle driving path parameters and driving time parameters; and the data processing module is used for calculating the current consumed power and correcting the power point lookup table. According to the system, the vehicle driving intention is set, map software is combined, the vehicle demand power is calculated in advance, the energy management module can intervene and distribute the fuel cell and the super capacitor in advance, it is guaranteed that the real-time output demand power of the vehicle in the driving distance is met, and dynamic optimization distribution of the fuel cell and the super capacitor is achieved; and the output power of the fuel cell and the super capacitor is in respective high-efficiency regions.

Description

technical field [0001] The invention relates to the technical field of a fuel cell-supercapacitor hybrid power system for a vehicle, 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 a suitable matching power source. [0003] Existing fuel cell vehicles generally use a fuel cell-power battery hybrid system, or a fuel cell-power battery-supercapacitor hybrid system, both of which are used in manned fuel cell vehicles. However, unmanned vehicles cannot obtain the driver's operating intentions, and it is difficult to accurately obtain the required power of the vehicle, which in turn causes problems such as the vehicle's inability to output the required power in rea...
