Variable Battery Charging Threshold for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery charging in mobile devices, such as laptops, relies on a fixed battery level threshold for fast-charging, which reduces battery lifespan and lacks flexibility in managing charging based on user-specific circumstances.
Innovation Solution
A battery charging arrangement that dynamically adjusts the charging threshold based on user-specific factors like schedule and calendar, allowing for variable fast-charging and slow-charging protocols depending on the duration of computer downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If fast-charging is used to reduce charging time, then charging speed is improved, but battery lifespan is reduced
Solution Approach 1:
The patent applies dynamics by making the charging threshold variable rather than fixed. The threshold dynamically adjusts based on predicted device usage patterns and downtime, allowing the system to optimize between fast-charging speed and battery lifespan preservation in different scenarios
Solution Approach 2:
The system performs preliminary action by predicting future device usage patterns and downtime before making charging decisions. This allows the threshold to be pre-adjusted based on anticipated scenarios, enabling optimal charging strategy selection in advance
2Ease of operation
If a fixed battery level threshold is used for fast-charging, then charging management is simplified, but flexibility in managing charging based on user circumstances is reduced
Solution Approach 1:
The system applies self-service by automatically predicting device usage patterns and adjusting the charging threshold without user intervention. The intelligent agent autonomously monitors device state, predicts scenarios, and makes charging decisions, eliminating the need for manual user configuration while providing adaptive charging management

AI summary
For laptops or other mobile devices, a battery charging arrangement wherein fast-charging and/or slow-charging is governed by something other than a fixed, immovable battery level threshold. Particularly, a variable threshold is broadly contemplated herein which may be governed by any of a very wide variety of conceivable factors, including (but by no means limited to) information relating to a user's schedule or calendar, especially as regards “free” time when a user is not using a computer. Accordingly, if there is a long uninterrupted period of computer “downtime” (i.e., when a user is not using the computer), the battery level threshold below which fast-charging takes place can be lower. By the same token, for short periods of computer downtime, this threshold can be higher. In this manner, fast-charging is reserved only for the most compelling, time-based circumstances.
