Solution Overview
Problem
Fuel cell vehicles face difficulties in finding available hydrogen charging stations with sufficient hydrogen, leading to inconvenience and potential travel disruptions due to insufficient hydrogen storage, as existing systems lack real-time information sharing for optimal charging.
Innovation Solution
A guide system and method that estimates the remaining hydrogen chargeable amount and charging time at specific stations, transmitting this information via an Internet network to connected fuel cell vehicles, using infrared communication between vehicles and chargers, and a server to index and record charging data, allowing vehicles to calculate and display optimal charging stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a driver visits the closest hydrogen charging station, then the traveling distance is minimized, but the hydrogen charging may fail due to insufficient hydrogen storage at the station
Solution Approach 1:
The system performs preliminary actions by having vehicles transmit charging completion information to the server in advance. The server then proactively notifies other vehicles of available hydrogen storage at charging stations before they arrive, allowing drivers to plan their routing ahead of time and avoid stations with insufficient hydrogen supply.
Solution Approach 2:
The system implements feedback mechanisms where vehicles report their charging status and hydrogen consumption to the server. The server continuously updates the hydrogen storage status of charging stations based on this feedback and communicates real-time availability information back to vehicles, enabling dynamic routing decisions.
2Reliability
If a driver moves to a remote hydrogen charging station with sufficient hydrogen, then the hydrogen charging availability is improved, but the traveling distance increases and causes traffic congestion
Solution Approach 1:
The server receives real-time feedback from charging stations about hydrogen storage levels and dynamically adjusts routing recommendations. When multiple vehicles are directed to the same remote station, the server monitors the hydrogen consumption rate and can redirect subsequent vehicles to alternative stations, preventing traffic congestion while ensuring charging availability.
Solution Approach 2:
The system dynamically adjusts charging station recommendations based on real-time conditions. As vehicles charge and hydrogen levels change, the server updates the available station list and re-routes vehicles accordingly, creating a flexible system that adapts to changing conditions rather than using fixed routing.
3Productivity
If real-time hydrogen charging information is shared among vehicles, then the hydrogen charging smoothness is improved, but the system complexity increases
Solution Approach 1:
The server acts as an intermediary that centralizes the collection, processing, and distribution of hydrogen charging information. Vehicles communicate with the server through standardized protocols, and the server manages the complexity of real-time data processing, matching algorithms, and information distribution, thereby simplifying the overall system architecture while enabling efficient information sharing.

AI summary
The present disclosure provides a system and a method for guiding hydrogen charging, which may estimate a remaining hydrogen chargeable amount (remaining hydrogen storage amount), a charging time, and the like of a hydrogen charging station, and provide the estimated information to another vehicle to be charged through an Internet network when a driver charges hydrogen in a hydrogen tank of his/her fuel cell vehicle at the hydrogen charging station, such that the driver of the vehicle to be charged may recognize a maximum chargeable amount and a required charging time for a hydrogen tank of a vehicle to be charged for each hydrogen charging station, thereby allowing the fuel cell vehicles to visit the hydrogen charging station and smoothly charge hydrogen.
