EV Power Aggregation Cable for Higher External Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles often have limited output capacity through their charging ports and chargers, making it difficult to supply the requested amount of electric power to external electric power consumers.
Innovation Solution
An electric energy transmission cable system that electrically couples outputs of two different power sources in an electric vehicle, allowing for the aggregation and increased delivery of electric power to external loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the vehicle charging port and charger are used for power delivery, then electric power can be supplied to external consumers, but the output capacity is limited and cannot meet high power demands
Solution Approach 1:
The system dynamically adjusts power delivery parameters based on real-time cable configuration detection. The charging port identifies cable insertion status and electrical characteristics, then adapts operating parameters such as current limits and voltage levels to match the connected cable's capabilities, enabling safe operation across multiple power levels without requiring separate hardware for each cable type
Solution Approach 2:
The patent changes electrical parameters (current, voltage, power limits) based on detected cable configurations. The system measures electrical characteristics upon cable connection and modifies delivery parameters accordingly, allowing the same charging port to safely support both high-power and low-power cable configurations by adjusting operational parameters rather than requiring physical hardware changes
2Power
If multiple power sources are aggregated to increase power output, then higher power can be delivered to external loads, but the system complexity increases
Solution Approach 1:
The patent merges multiple power sources (vehicle charging port and vehicle power take-off) into a single aggregated power delivery system. By combining these sources through a unified control architecture, the system achieves higher total power output while maintaining manageable complexity through centralized management rather than separate independent systems
Solution Approach 2:
The charging port system is designed to perform multiple functions: it can detect various cable configurations, communicate with different cable types, and deliver power at multiple power levels. This multi-functionality reduces overall system complexity by using a single versatile interface rather than requiring separate dedicated interfaces for each cable type or power level
