Title:
VEHICLE CONTROL SYSTEM FOR HYDROGEN-ENERGY BICYCLE, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/067460
Kind Code:
A1
Abstract:
Disclosed are a vehicle control system for a hydrogen-energy bicycle and a control method. The control method comprises: providing a lithium battery pack, which supplies power to a central control system and a hydrogen fuel cell management system when a hydrogen-energy bicycle is started, and only supplies power to the central control system and an instrument after the hydrogen-energy bicycle is started; providing the hydrogen fuel cell management system, involving: making the hydrogen fuel cell management system not include control over the charging of the lithium battery pack; and providing a fuel cell stack, involving: dividing an output of the fuel cell stack into two paths, wherein one path passes through a DC-DC boost circuit and is then connected to an electric-motor controller, and the other path passes through a DC-DC buck circuit and is then connected to the hydrogen fuel cell management system. By means of the control method, after being started, a lithium battery pack does not supply power to a hydrogen fuel cell management system any more, such that the electric quantity of a lithium battery is saved on, and the standby power consumption of the lithium battery can be reduced when a system is shut down, thereby realizing long-time standby; moreover, the aim of facilitating the usage of a user by means of providing a hydrogen-energy bicycle, the traveling power of which is provided by hydrogen energy, is achieved.
