Charging System Power Allocation via Current Threshold Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging systems face challenges in allocating power between the charging power source and the auxiliary power source, often prioritizing the auxiliary power source, which can lead to insufficient charging of digital devices and reduced flexibility.
Innovation Solution
A charging method and system that detect both the auxiliary current value and the total charging current value, stopping the auxiliary power source when the sum exceeds a threshold, ensuring that the charging power source can effectively charge digital devices while maintaining auxiliary power source flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the power demand of the auxiliary power source is always given priority, then the auxiliary power source can maintain its flexibility, but the charging power source may not output enough power to charge the digital devices
Solution Approach 1:
The patent implements dynamic power allocation by continuously monitoring the power demands of both the auxiliary power source and charging power source, and adjusting the power distribution in real-time based on current system conditions rather than maintaining a fixed priority scheme
Solution Approach 2:
The system employs feedback mechanisms where the controller receives information about the power demands of both power sources and adjusts the power allocation accordingly, ensuring that digital devices receive sufficient charging power while maintaining auxiliary power source flexibility
2Power
If the upper power limitation is set in advance to ensure enough charging power, then the charging power source can charge digital devices, but the power source capacity of the auxiliary power source is sacrificed
Solution Approach 1:
The system transitions from static pre-configured power limits to dynamic power allocation that adapts to real-time conditions, allowing the auxiliary power source capacity to be utilized when needed while ensuring charging requirements are met
Solution Approach 2:
The patent changes the power allocation parameters dynamically based on system conditions, adjusting the power distribution between auxiliary and charging power sources according to actual demand rather than fixed predetermined values
3Productivity
If dozens of devices are charging simultaneously, then the charging system can serve multiple devices, but the power system may be overloaded
Solution Approach 1:
The patent implements power zone allocation where the charging power source is divided into multiple independent power zones, each capable of serving specific devices independently, allowing simultaneous charging of multiple devices while preventing system-wide overloading
Solution Approach 2:
The system segments the charging power source into multiple power zones with independent power allocation, enabling parallel charging operations while maintaining overall system stability through distributed power management

AI summary
A charging method includes the following operations: charging an auxiliary power source and at least one charging power source simultaneously, in which a power demand of the auxiliary power source is a first consideration, and a power demand of the at least one charging power source is a second consideration; detecting an auxiliary current value of the auxiliary power source and a total charging current value of the at least one charging power source; and stopping charging the auxiliary power source when a sum of the auxiliary current value and the total charging current value is greater than a current threshold value.
