Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging systems for electric vehicles do not effectively account for the individual needs of the driver along their route, leading to inefficient charging processes and potential battery depletion during long-distance journeys.
Innovation Solution
A charging system that includes a software application on a mobile device or navigation system, which facilitates dynamic charging by connecting electric vehicles with mobile charging vehicles, determining a common meeting point and time based on the vehicles' positions and routes, and providing navigation instructions for efficient charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electric vehicles use fixed charging stations, then charging infrastructure is established, but drivers must detour to charging stations located far from their planned route
Solution Approach 1:
The patent transforms fixed charging stations into mobile charging vehicles that can dynamically position themselves along the driver's planned route. The charging vehicle travels to a meeting point on the driver's route, eliminating the need for detours to distant fixed stations. This dynamic approach allows charging services to adapt to the driver's location and schedule.
Solution Approach 2:
The patent introduces a software application as an intermediary between the driver and charging vehicle. The application coordinates the charging request, calculates the meeting point on the driver's route, and facilitates the arrangement between driver and charging vehicle operator, enabling seamless dynamic charging coordination.
2Device complexity
If charging capacity is concentrated at fixed stations, then infrastructure investment is reduced, but charging points may be exhausted due to high customer demand
Solution Approach 1:
The patent segments the centralized charging infrastructure into multiple mobile charging vehicles distributed across different locations. Instead of one large fixed station, multiple smaller charging vehicles can serve different areas simultaneously, reducing the risk of complete system failure and improving overall availability.
Solution Approach 2:
Mobile charging vehicles can dynamically relocate to areas with high demand, adjusting their positions based on real-time charging requests and route calculations. This dynamic distribution prevents charging point exhaustion by spreading capacity across multiple mobile units rather than concentrating it at fixed locations.
3Adaptability or versatility
If mobile charging vehicles are used, then charging flexibility along the route is improved, but coordination and scheduling complexity increases
Solution Approach 1:
The software application serves as an intermediary that automatically handles the coordination complexity. It calculates optimal meeting points on the driver's route, communicates with charging vehicle operators, and manages scheduling, thereby reducing the perceived complexity for users while enabling flexible charging arrangements.
Solution Approach 2:
The system enables self-service through automated route calculation and meeting point determination. The software application autonomously coordinates between driver and charging vehicle without requiring manual negotiation, reducing coordination complexity while maintaining high flexibility.
