Problems solved by technology
For example, in the process of going uphill, due to the high power required by the motor of the moped, the output current of the hydrogen fuel cell will also change dynamically, which may easily cause damage and overload of the hydrogen fuel cell stack.
[0004] As a result, hydrogen fuel cell stacks are often paired with lithium batteries to form a hydrogen energy moped. However, the existing hydrogen energy mopeds still rely mainly on the electric energy of the lithium battery, which has not fully utilized hydrogen energy.

The invention provides a hydrogen fuel cell stack power supply method and system, a hydrogen energy moped and its transmission method and system. The power supply method includes: controlling the chip to detect the working status of the hydrogen fuel cell stack and lithium battery pack; When the battery stack and the lithium battery pack are not faulty, obtain the output voltage of the lithium battery pack; when the output voltage is lower than the charging threshold, the hydrogen fuel cell stack supplies power to the lithium battery pack; when the output voltage is higher than the charging stop threshold, Disconnect the power supply circuit from the hydrogen fuel cell stack to the lithium battery pack; when the output voltage is greater than or equal to the charging threshold and less than or equal to the charging stop threshold, maintain the power supply circuit from the hydrogen fuel cell stack to the lithium battery pack; when the output voltage is higher than When the charging threshold is stopped, the power supply circuit from the hydrogen fuel cell stack to the lithium battery pack is disconnected. After adopting the above technical solution, under the protection of the hydrogen fuel cell stack, the hydrogen energy is used as much as possible as the power assisting electric energy of the moped.
Description
technical field [0001] The invention relates to the field of energy management, in particular to a hydrogen fuel cell stack power supply method and system, a hydrogen energy moped and its transmission method and system. Background technique [0002] A hydrogen fuel cell is a device that uses hydrogen as a fuel to generate electricity through a chemical reaction with oxygen, and its by-product is only water. Therefore, hydrogen fuel cells have been rapidly developed in the field of transportation equipment. The source of electric energy for motor vehicles and non-motor vehicles. Therefore, bicycles powered by hydrogen fuel cells have become an ideal green travel vehicle. [0003] Since the hydrogen fuel cell is based on the diffusion of hydrogen and oxygen in the electrolyte, its dynamic response speed is related to its diffusion speed. Therefore, it is not suitable for applications with high frequency and large dynamic load changes. During the use of mopeds, electric power...
