Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle battery charging systems do not effectively allow users to set charge amounts based on specific user situations, such as navigation destinations and real-time traffic information, limiting flexibility and accuracy in battery charging.
Innovation Solution
A vehicle system and method that includes a display, input, and processor to set a distance-to-empty (DTE) value or charge time, allowing users to input preferences through a user interface, and charging the battery accordingly, considering navigation destinations and real-time traffic information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users set charge amount based on fixed percentages (80%, 100%), then charging operation is simple, but it does not adapt to specific user situations such as navigation destinations and traffic conditions
Solution Approach 1:
The system performs preliminary calculations of required charge amounts based on navigation destinations and traffic information before the user initiates charging. The processor calculates the distance to the destination, estimates energy consumption considering real-time traffic conditions, and determines the optimal charge amount in advance, so when the user starts charging, the appropriate charge level is already prepared and presented for confirmation.
2Measurement precision
If the system provides detailed information about navigation destinations and traffic conditions for charging decisions, then charging accuracy improves, but information processing complexity increases
Solution Approach 1:
The system merges multiple information sources including navigation destination data, real-time traffic information, and battery status into a single integrated processing framework. The processor combines these diverse data streams to comprehensively calculate the required charge amount, presenting a unified charging recommendation that considers all factors simultaneously rather than processing them separately.
Solution Approach 2:
The processor acts as an intermediary that receives raw data from navigation and traffic information systems, processes and translates this data into meaningful charging parameters, and presents the processed information to the user in an understandable format. This intermediary function simplifies the complexity by hiding the detailed processing steps while providing accurate charging recommendations.
3Reliability
If the system calculates charge amounts based on real-time traffic information and navigation data, then charging suitability improves, but calculation time increases
Solution Approach 1:
The system performs preliminary calculations of required charge amounts based on navigation destinations and traffic information before the user initiates charging. The processor calculates the distance to the destination, estimates energy consumption considering real-time traffic conditions, and determines the optimal charge amount in advance, so when the user starts charging, the appropriate charge level is already prepared and presented for confirmation.
