EV Navigation System Resolving Range Anxiety via Dual Route Options
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicle drivers experience range anxiety due to limited driving ranges and recharge times, leading to poor decision-making regarding charging stops during trips.
Innovation Solution
A method providing two navigation routes for electric vehicles: one with a charging stop and another without, along with customizable settings to limit energy consumption, allowing drivers to select routes based on their preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a charging stop is included in the route to ensure the electric vehicle can reach the navigation destination, then the reliability of reaching the destination is improved, but the travel time increases due to the charging stop
Solution Approach 1:
The navigation system dynamically adjusts the state of charge threshold based on route characteristics, vehicle consumption patterns, and charging infrastructure availability. This allows the system to optimize between including and excluding charging stops based on real-time conditions, resolving the contradiction between reliability and travel time
2Reliability
If the driver charges the battery more frequently to avoid range anxiety, then the reliability of reaching the destination is improved, but the productivity of the trip decreases due to more charging stops
Solution Approach 1:
The system continuously monitors the actual energy consumption of the vehicle and compares it with predicted consumption. This feedback loop allows the navigation system to adjust the state of charge threshold and routing recommendations in real-time, optimizing the balance between reliability and productivity based on actual vehicle performance rather than conservative estimates
3Loss of information
If the navigation system provides detailed consumption metrics and factors, then the information completeness is improved, but the device complexity increases making it harder for drivers to make decisions
Solution Approach 1:
The navigation system extracts and highlights only the most critical information needed for decision-making, such as the recommended state of charge threshold and key route options. Detailed consumption metrics and factors are available on demand but not prominently displayed, reducing the information overload while maintaining completeness for those who need it
