Multi-Input EV Charging Layout for Shorter Charging Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The slow charging time of electric vehicles due to the limited availability of charging stations and the need for sequential charging using a single input, which contrasts with the faster refueling of gasoline-powered vehicles.
Innovation Solution
Modifying electric vehicles and charging stations to enable simultaneous charging using multiple charging inputs, including the use of multiple charging station plug-ins, AC and DC chargers, and repositioning of charging connectors to accommodate concurrent charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If multiple charging inputs are used simultaneously, then charging time is reduced, but device complexity increases
Solution Approach 1:
The patent divides the charging system into multiple independent charging inputs (first charging input, second charging input) that can operate simultaneously. Each input has its own charging connector and control circuitry, allowing parallel charging operations to reduce total charging time while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
The patent transitions from single-dimension sequential charging to multi-dimensional parallel charging by adding spatial distribution of multiple charging connectors at different locations on the vehicle. This dimensional expansion allows simultaneous charging operations without proportionally increasing control complexity, as each connector operates semi-independently.
2Productivity
If multiple charging station plug-ins are used, then charging speed increases, but ease of operation decreases
Solution Approach 1:
The patent incorporates automatic detection and selection capabilities where the vehicle's charging system automatically identifies available charging stations and manages the distribution of power across multiple inputs. This self-service functionality allows parallel charging to occur without requiring complex user intervention, maintaining ease of operation while achieving high charging speeds.
Solution Approach 2:
The system dynamically adjusts charging parameters such as power distribution ratios, voltage levels, and current allocation across multiple charging inputs based on real-time conditions. This automatic parameter optimization enables fast charging while simplifying user interaction, as the system handles complex parameter management without user input.
