Description

Technical Field

[0001] This invention relates to the field of hydrogen fuel cell vehicle training technology, and in particular to a hydrogen fuel cell vehicle power system installation training platform. Background Technology

[0002] Hydrogen fuel cell vehicles are automobiles that use hydrogen as their primary energy source for propulsion. While conventional internal combustion engines typically use diesel or gasoline, hydrogen vehicles use gaseous hydrogen. Fuel cells and electric motors replace conventional engines. The principle of a hydrogen fuel cell is that hydrogen is fed into the fuel cell, where electrons from hydrogen atoms are blocked by a proton exchange membrane and conducted from the negative electrode to the positive electrode through an external circuit, generating electricity to drive the electric motor. Protons, however, can pass through the proton exchange membrane and combine with oxygen to form pure water mist, which is then released. This process is clean and hygienic, as the product of hydrogen combustion is water, which does not pollute the environment. Furthermore, hydrogen has a higher calorific value than gasoline when burned.

[0003] Based on the arrangement of the fuel cell power unit and its connection to the drive motor, FCV power system configurations can be divided into two categories: direct hybrid and indirect hybrid. For example... Figure 1 As shown, in a fuel cell vehicle with a direct hybrid power configuration, the proton exchange membrane fuel cell system directly connects to the motor controller and uses a power battery / supercapacitor as its auxiliary energy supply device. The power battery / supercapacitor is connected to the motor controller via a bidirectional DC / DC converter; as shown... Figure 2 As shown, in a fuel cell vehicle with an indirect hybrid power configuration, the proton exchange membrane fuel cell system matches the input voltage through a battery controller and a unidirectional DC / DC converter, and controls the power output in this way. Similarly, the power battery / supercapacitor is used as an auxiliary energy supply device, and then it is directly connected to the positive terminal of the DC bus of the motor controller.

[0004] Currently, training institutions and universities provide limited training on hydrogen fuel cell vehicle power systems, which mainly consists of theoretical lectures and explanations of principles. The training effectiveness is poor, and targeted teaching systems are in very short supply.

[0005] A search revealed that Chinese patent application number "202123254828.4" discloses a training platform for installing a hydrogen fuel cell vehicle power system. The platform includes a training base and a hydrogen fuel cell vehicle body. A tension plate is installed at one end of the training base, and a tension sensor is installed inside the tension plate. A tension rope is installed on one side of the tension sensor. The hydrogen fuel cell vehicle body is placed on the upper side of the training base. A front protective shell and a rear protective shell are respectively installed at both ends of the upper side of the hydrogen fuel cell vehicle body. A lifting and adjusting mechanism is provided on the lower side of the hydrogen fuel cell vehicle body. A collision protection plate is installed on the upper side of one end of the training base, and a collision protection mechanism is installed on one side of the collision protection plate. This invention, with its training base, tension sensor, and hydrogen fuel cell vehicle body, facilitates power tensile testing of hydrogen fuel cell vehicles. It has a simple structure, is easy to operate, and the collision protection plate and mechanism installed on the upper side of one end of the training base provide collision protection for one end of the hydrogen fuel cell vehicle body, improving safety during tensile testing.

[0006] However, the aforementioned hydrogen fuel cell vehicle power system installation training platform cannot present the components and interrelationships of the power system to the trainees, resulting in superficial learning and an inability to combine theory with practical components, leading to poor learning outcomes.

[0007] In conclusion, there is an urgent need for a hydrogen fuel cell vehicle power system installation training platform to solve the above problems. Summary of the Invention
