Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric vehicle charging systems require separate interfaces for fast and slow charging, limiting the ability to manage both modes in an integrated manner and necessitating physically distinct ports, which is not efficiently scalable or user-friendly.
Innovation Solution
A system and method that utilize a common combo connector to dynamically schedule and switch between fast and slow charging modes based on the availability of fast charging modules, user input, and charging priorities, allowing for real-time adjustment of charging power allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate interfaces are used for fast charging and slow charging, then each charging mode can be independently implemented, but the system complexity increases and scalability is limited
Solution Approach 1:
The patent combines separate fast charging and slow charging interfaces into a single combo connector that supports both charging modes. The connector includes multiple pins that can be configured to provide either DC fast charging or AC slow charging functionality, eliminating the need for physically separate ports while maintaining reliable independent operation of each charging mode through controlled configuration
Solution Approach 2:
The combo connector is designed as a universal interface that can perform multiple functions - supporting both fast charging and slow charging modes within a single physical connector. The connector's pin configuration and control logic enable it to adaptively provide different charging modes based on system requirements and availability, improving scalability while reducing interface complexity
2Device complexity
If a common combo connector is used for both fast and slow charging, then interface complexity is reduced and scalability is improved, but dynamic management of charging modes becomes more challenging
Solution Approach 1:
The patent implements dynamic charging mode management where the system can automatically switch between fast charging and slow charging modes based on real-time conditions such as fast charging module availability, user preferences, and system load. The combo connector's pin configuration and control logic are designed to dynamically reconfigure the charging mode during operation, enabling automated adaptation without requiring complex manual management
Solution Approach 2:
The system incorporates feedback mechanisms that monitor fast charging module availability and system state, then automatically adjust the charging mode accordingly. When fast charging modules become unavailable, the system receives feedback about this condition and dynamically switches to slow charging mode, maintaining optimal operation while simplifying interface management through automated decision-making based on real-time system state
3Ease of operation
If fast charging is prioritized when modules are available, then user satisfaction improves, but system load management becomes more difficult
Solution Approach 1:
The system dynamically adjusts charging mode allocation based on real-time system load conditions and fast charging module availability. When fast charging modules are available and system load is manageable, the system prioritizes fast charging to improve user satisfaction. When system load becomes excessive or fast charging modules are unavailable, the system automatically transitions to slow charging mode, maintaining power balance while still providing acceptable service
Solution Approach 2:
The system changes operational parameters such as charging power level and mode selection based on system load conditions. By monitoring power consumption and module availability, the system dynamically adjusts the charging parameters - switching between high-power fast charging and lower-power slow charging modes - to balance user satisfaction with system load management, ensuring sustainable operation while responding to user needs

AI summary
A method for dynamically charging an electrically powered apparatus includes receiving a selection of a charging mode from a user, such that the selected charging mode is a fast charging mode or a slow charging mode. The method also includes dynamically scheduling a charging mode for charging the apparatus according to the selected charging mode and a status of a fast charging module, and electrically charging the apparatus according to the dynamically scheduled charging mode.
