Vehicle structure arrangement of minisize fuel battery cargo van

Abstract

The invention relates to a vehicle structure arrangement of a minisize fuel battery cargo van. Secondary development is performed on a 2.5T fuel type minisize truck. A 10kW fuel battery stack 3, a fuel battery controller, a hydrogen supply system, a hydrogen leakage alarming system 4, a hydrogen adding system 5, a hydrogen storing tank 8, a fuel battery cargo van special instrument, a central cooling system 1, a lithium battery and lithium battery management system 10, an electric drive axle system 13, a motor controller 12 matched with a fuel battery, and a vehicle controller 9 matched with the fuel battery are loaded on a cargo van frame 2, wherein the 10kW fuel battery stack 3 is arranged at the lower part of a cargo box 15; the central cooling system 1 is arranged at the front end of the cargo van frame 2; the vehicle controller 9 is arranged under a co-driver seat; the lithium battery and lithium battery management system 10 is arranged in a high-voltage box; and a high-voltage distributing box 11 and the motor controller 12 are arranged behind the lithium battery. According to the vehicle structure arrangement disclosed by the invention, a minisize cargo van of which the total weight is 2.2 T can achieve a loading capacity of 600 KG, is low in noise, and can realize non-pollution discharging; and the battery range between two loading processes is greater than 250Km, and time for loading fuel is 3-5 minutes.

Description

technical field [0001] The invention belongs to the technical field of complete vehicle arrangement of fuel cell electric vehicles, and in particular relates to a complete vehicle structural arrangement of a miniature fuel cell logistics vehicle. Background technique [0002] Fuel cell electric vehicles belong to the third generation of environmentally friendly vehicles. Fuel cells are used as power sources, which directly convert the chemical energy of fuel into electrical energy, and drive the motor through electrical energy to make the vehicle run. [0003] Fuel cell electric vehicles overcome the shortcomings of short driving range and long charging time of pure electric vehicles powered by lithium batteries. Compared with traditional internal combustion engine vehicles, fuel cells do not go through the heat engine process and are not limited by the Carnot cycle. They have the incomparable advantages of internal combustion engine vehicles such as high energy conversion e...

Problems solved by technology

[0005] Disadvantages of traditional fuel mini logistics vehicles: high emissions and high noise

[0006] Disadvantages of pure electric micro-logistics vehicles: Lithium batteries are heavy, and the installation of lithium batteries on micro-logistics vehicles is limited to ensure the load capacity, resulting in insufficient mileage

In order to ensure the loading quality of pure electric mini logistics vehicles, there are strict restrictions on the quality of the whole vehicle, which leads to a very strict upper limit on the total weight of the battery loaded on the vehicle.

The assembly volume of lithium batteries is limited, resulting in insufficient maximum mileage of pure electric mini logistics vehicles
