Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicles are limited by single charging ports that comply with international standards, resulting in inefficient and time-consuming charging processes, with most Level 2 chargers providing only about 19 KW of A/C power and 18-28 miles per hour of charge.
Innovation Solution
A multi-port charging assembly that combines the charge from at least two independent electric vehicle chargers through a single output, utilizing a micro-processor to balance and adjust the input charges based on the vehicle's requirements, providing an increased charge beyond what a single charger can deliver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single charging port is used to comply with international standards, then the device meets standardization requirements, but the charging speed and efficiency are limited to 18-28 miles per hour
Solution Approach 1:
The patent combines multiple charging ports (first charging port and second charging port) into a single integrated charging assembly that can simultaneously receive power from multiple sources. The controller merges the electrical inputs from both ports and delivers combined power through a single output connection to the vehicle battery, thereby increasing charging speed without requiring multiple separate connections to the vehicle.
Solution Approach 2:
The charging assembly is designed to perform multiple functions: it can accept power from a single charging port or simultaneously accept power from multiple charging ports. The controller dynamically manages the input sources, allowing the system to adapt between single-source and multi-source charging modes, providing universal compatibility with different charging configurations while optimizing charging efficiency.
2Productivity
If multiple independent chargers are connected to combine charge, then charging efficiency increases, but the system complexity and coordination difficulty increase
Solution Approach 1:
The controller continuously monitors the electrical parameters (voltage, current, power) from each charging port and the battery's charging status. Based on this feedback, the controller dynamically adjusts the power distribution from each input source, balances the charging load, and manages the combined output to the battery. This closed-loop control system coordinates multiple chargers automatically, eliminating the need for complex manual coordination while maximizing charging efficiency.
3Loss of time
If the charging assembly combines and adjusts input charges dynamically, then charging time is reduced, but the control system complexity increases
Solution Approach 1:
The controller is pre-programmed with charging algorithms and parameters that enable it to automatically manage multiple input sources upon connection. The system performs preliminary assessments of each charging port's capabilities and pre-configures the power distribution strategy before beginning the charging process. This preliminary setup allows the controller to efficiently combine and adjust charges without requiring complex real-time decision-making, thereby reducing charging time while keeping the control system manageable.
