Adaptive Battery Charging via Dynamic Port Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery charging methods for electric vehicles and mobile devices do not effectively adapt to the state of the battery, leading to inefficient charging times and potential damage due to inappropriate fast charging.
Innovation Solution
A battery charging method that determines the number of charging ports based on the battery's state of charge, state of health, and temperature, using multiple ports for fast charging when appropriate and a single port for slow charging when conditions are not favorable, thereby optimizing charging efficiency and extending battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If fast charging is used to reduce charging time, then charging speed is improved, but battery damage risk increases
Solution Approach 1:
The charging system dynamically adjusts the charging mode between fast charging and normal charging based on real-time battery state monitoring. The controller changes charging parameters adaptively according to temperature, charge level, and battery health conditions, resolving the contradiction by making the charging speed flexible rather than fixed.
Solution Approach 2:
The system implements continuous feedback monitoring of battery temperature, charge state, and health metrics. Based on this feedback, the controller automatically adjusts or terminates fast charging when thresholds are exceeded, preventing battery damage while maximizing charging speed when conditions are favorable.
2Productivity
If multiple charging ports are used for fast charging, then charging efficiency is improved, but device complexity increases
Solution Approach 1:
The battery pack is divided into multiple independent battery sections, each with its own charging port. This segmentation allows parallel charging of different sections, significantly improving charging efficiency. The modular architecture manages complexity by creating independent, manageable charging circuits for each section.
Solution Approach 2:
The charging system is designed with multiple charging ports that can operate independently or in combination. Each port serves as a complete charging circuit capable of handling full charging tasks, providing universality and flexibility that manages system complexity through standardized, interchangeable components.
3Speed
If charging continues without monitoring battery state, then charging speed is maintained, but battery life is reduced
Solution Approach 1:
The system continuously monitors battery temperature, charge state, and health metrics during charging. This feedback mechanism allows the controller to adjust charging parameters in real-time, maintaining optimal charging speed while preventing conditions that would reduce battery life, such as overheating or overcharging.
Solution Approach 2:
The system establishes predetermined safety thresholds for temperature, charge level, and other battery parameters before charging begins. When these thresholds are approached during charging, the system proactively reduces or terminates charging current to prevent damage, cushioning against potential battery life reduction before it occurs.
