Travel Plan Rerouting for Unavailable EV Charging Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing travel plan generation systems fail to adapt when energy supply becomes unavailable at the scheduled charging facility during a vehicle's journey, leading to potential travel disruptions.
Innovation Solution
A travel plan generation device that dynamically identifies a second energy supply facility when the first facility becomes unavailable, generating an alternate route for the vehicle to pass through this facility instead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed charging facility is scheduled in the travel plan, then the travel plan can be generated in advance, but the system cannot adapt when energy supply becomes unavailable at the scheduled facility
Solution Approach 1:
The travel plan generation system dynamically adjusts the charging facility selection based on real-time supply availability information. The system transitions from a static pre-determined plan to a dynamic adaptive plan that can change the charging facility when supply becomes unavailable, resolving the contradiction between fixed scheduling and adaptability.
Solution Approach 2:
The system acquires supply availability information at predetermined timings and uses this feedback to determine whether to maintain or change the charging facility. This feedback mechanism enables the system to adapt to changing conditions while maintaining reliable energy supply.
2Reliability
If the system monitors supply availability at predetermined timings, then it can detect unavailable facilities, but this requires additional communication and processing
Solution Approach 1:
The system acquires supply availability information at predetermined timings before the vehicle arrives at the charging facility. This preliminary action allows the system to detect potential supply issues in advance and adjust the travel plan proactively, reducing the need for complex real-time monitoring during critical periods.

AI summary
A travel plan generation device includes a controller configured to: generate a travel plan in which a vehicle passes through a first supply facility for supplying energy of the vehicle; acquire first supply availability information indicating a vacancy state of a first supply facility after the vehicle starts traveling based on the generated travel plan; notify notification information indicating that there is no available charging station; determine whether or not supply of the energy is available at the first supply facility based on the first supply availability information of the first supply facility; and when determining that the supply of the energy is not available at the first supply facility, identify a second supply facility different from the first supply facility and generate the travel plan in which the vehicle passes through the second supply facility instead of the first supply facility.
