EV Group Route Guidance via Shared Charging Stops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems fail to provide effective route guidance for a group of electric vehicles to a destination while considering the remaining battery capacity of each vehicle, leading to potential dispersion and electricity shortages.
Innovation Solution
A navigation system that calculates the travelable distance of each electric vehicle based on its battery capacity and user-specific data, determines if the vehicle with the shortest travelable distance can reach the destination, and provides route guidance through charging stations for power replenishment, allowing the group to arrive collectively without dispersing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a navigation system guides a group of electric vehicles to a destination without considering individual battery capacities, then the route planning is simple, but the vehicles may disperse and some may run out of electricity
Solution Approach 1:
The system segments the group route planning into individual vehicle assessments by calculating travelable distances for each vehicle based on its specific battery capacity, weight data, and electricity consumption records, then integrates these individual plans into a coordinated group route that maintains cohesion while accounting for individual energy constraints
Solution Approach 2:
The system performs preliminary calculations of travelable distances for each vehicle before finalizing the group route, using stored weight data and electricity consumption records to predict energy usage and determine which vehicles require charging stops, allowing proactive route planning that prevents vehicle dispersion
2Measurement precision
If the system calculates travelable distance for each vehicle based on detailed user data, then the route accuracy improves, but the calculation complexity increases
Solution Approach 1:
The system pre-stores weight data for each user and historical electricity consumption records in advance, so that when route planning is needed, the calculation can directly reference these stored values rather than collecting and processing raw data in real-time, improving measurement precision while managing calculation complexity
Solution Approach 2:
The system creates a virtual model of each vehicle's energy characteristics by storing and referencing historical electricity consumption records, allowing accurate travelable distance calculations without requiring complex real-time measurements, as the system uses these stored profiles to predict energy usage patterns
3Reliability
If the system guides vehicles to charging stations individually, then each vehicle can maintain power, but the group disperses and loses coordination
Solution Approach 1:
The system merges individual vehicle charging needs into a coordinated group charging plan by identifying common charging stations that can serve multiple vehicles, scheduling charging stops so that vehicles remain together as a group while still receiving the power they need, thus maintaining both power supply reliability and group formation stability
Solution Approach 2:
The navigation system acts as an intermediary that coordinates between individual vehicle energy requirements and group cohesion goals, using calculated travelable distances to determine optimal charging stops that allow vehicles to refuel without breaking group coordination, effectively mediating between individual and collective needs
