Problems solved by technology

High-pressure gaseous hydrogen storage is widely used, easy to operate, low in cost, and fast in charging and discharging hydrogen, but it requires heavy pressure-resistant containers, consumes a lot of hydrogen compression work, and has unsafe factors such as hydrogen leakage and container explosion.
Cryogenic liquid hydrogen storage has a wide range of applications in hydrogen refueling stations around the world, but its application in vehicle-mounted systems is immature and has potential safety hazards
In addition, limited by technology, the cost of domestic liquid hydrogen application is very high

Abstract

The invention provides a power system of a battery-assisted bicycle. The power system of the battery-assisted bicycle comprises a hydrogen storage tank, a fuel cell stack, a control device, a drivingdevice and a bicycle frame, the bicycle frame comprises a front oblique beam, a connecting pedal and a main vertical pipe, the two ends of the connecting pedal are connected with the lower end of thefront oblique beam and the lower end of the main vertical pipe respectively, and the front oblique beam and the main vertical pipe are hollow. An exhaust channel communicating with the inner space ofthe front oblique beam and the inner space of the main vertical pipe is arranged in the connecting pedal, and an exhaust outlet is formed in the top of the main vertical pipe. The fuel cell stack is arranged in the front oblique beam, the hydrogen storage tank is arranged in the main vertical pipe, and hot air exhausted by the fuel cell stack enters the main vertical pipe through the exhaust channel, flows through the outer surface of the hydrogen storage tank and then is exhausted from the exhaust outlet. Waste heat generated during operation of the fuel cell stack is utilized to realize thermal compensation.

Description

technical field [0001] The present invention relates to the technical field of electric bicycles, hydrogen storage technology and fuel cell technology, in particular, the present invention relates to a power system of a battery-assisted bicycle. Background technique [0002] Hydrogen energy is considered to be an ideal clean energy, which has the advantages of light weight, abundant reserves, and environmental friendliness. The main industrial chain of hydrogen energy includes upstream hydrogen production, midstream hydrogen transportation and storage, downstream hydrogen refueling stations, hydrogen fuel cells and applications. Midstream hydrogen storage includes high-pressure gaseous hydrogen storage, low-temperature liquid hydrogen storage and solid-state hydrogen storage. High-pressure gaseous hydrogen storage is widely used, easy to operate, low in cost, and fast in charging and discharging hydrogen, but it requires heavy pressure-resistant containers, consumes a lot o...
