A recent patent by the State Grid Zhejiang Jiashan Power Supply, filed on October 10, 2024, outlines a control system and method for a hydrogen-powered vehicle-mounted mobile generator.
The control system described in the patent comprises several key components working collaboratively to ensure efficient energy management. Central to this system is the vehicle controller, which interfaces with a hydrogen storage system. The storage system is pivotal for maintaining an adequate supply of hydrogen, which is then utilized by a hydrogen fuel battery pack.
Critical to the operational efficiency of this system are the DC/DC converters. The first converter connects to the vehicle controller, while the second DC/DC converter plays a dual role. It links both the hydrogen fuel battery pack to a power conditioning system (PCS) and to a buffer lithium battery system. This setup ensures the seamless conversion and management of energy across the different components.
A prominent feature of this patent is the inclusion of a centralized monitoring system. This system is tasked with overseeing the charging and discharging cycles of the buffer lithium battery. Through intelligent control, the system can adapt the power generation of the hydrogen storage and fuel battery system to manage peak load effectively. This results in a more efficient and flexible power usage model.
The PCS is further connected to an off-grid switching device, highlighting the system’s capability to operate independently of the main power grid. This feature is particularly valuable in scenarios where grid power is unavailable or unreliable, offering a stable power supply when and where it is needed.
