Telematic Reserve Charge Authorization for Electric Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicle users experience driving range anxiety due to the scarcity of charging stations, as existing systems fail to efficiently utilize the vehicle's reserve charge to navigate to nearby recharging points, leading to potential strandings and increased stress.
Innovation Solution
A telematic authorization system that connects the vehicle's processor with a remote device to determine the reserve charge level and location, allowing for the authorization of reserve charge usage to power the vehicle, enabling navigation to the nearest charging station while ensuring safety and reducing user stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle restricts access to reserve charge to maintain battery performance, then battery reliability is improved, but driving range and user mobility deteriorate
Solution Approach 1:
The system performs preliminary assessment of charging infrastructure availability and vehicle state before authorizing reserve charge usage. The remote server evaluates whether nearby charging stations exist and whether authorizing reserve charge would be beneficial, preventing premature or unnecessary reserve charge depletion while enabling it when strategically appropriate.
Solution Approach 2:
The system implements bidirectional feedback loops between the vehicle, remote server, and charging infrastructure. The server receives real-time data about charging station availability, battery state, and location, then provides authorization decisions back to the vehicle. This feedback mechanism allows dynamic adjustment of reserve charge accessibility based on current conditions rather than static restrictions.
2Reliability
If the vehicle provides telematic communication capabilities, then user assistance and safety are improved, but device complexity increases
Solution Approach 1:
The remote server acts as an intermediary between the vehicle and charging infrastructure, handling complex communication and decision-making logic centrally rather than in the vehicle. The vehicle's telematic system only needs to exchange standardized messages with the server, reducing onboard complexity while maintaining sophisticated functionality through server-side processing.
3Use of energy by moving object
If the vehicle requires remote authorization for reserve charge usage, then energy utilization efficiency is improved, but response time and user convenience deteriorate
Solution Approach 1:
The system pre-assesses charging infrastructure availability and vehicle state before authorization is needed. By evaluating whether nearby charging stations exist and whether reserve charge authorization would be beneficial in advance, the system minimizes decision-making time when the driver actually needs authorization, enabling faster response when conditions are favorable.

AI summary
A system for an electric vehicle for authorizing the utilization of a reserve charge portion of a battery of the electric vehicle for powering the electric vehicle. The authorization system may include a remote device that communicates with the electric vehicle via a telematic link. Upon receipt of one or more data from the electric vehicle (e.g., reserve charge amount of the battery, recharge locations, warranty waiver information, billing information, previous authorization information, etc.) the remote device transmits an authorization signal to the electric vehicle for using at least part of the reserve charge portion of the battery based upon the data. The authorization system may incorporate live personnel for determining whether to authorize the electric vehicle or such authorization may be determined automatically by a processor of the remote device. The authorization system may be entirely local to the electric vehicle such that no remote device is needed.
