Smart Battery Balance System for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices often experience battery imbalance, where the peripheral device's battery drains faster than the mobile computing device's battery, leading to wasted energy and reduced system uptime, as the mobile device cannot charge the peripheral device due to compatibility issues.
Innovation Solution
A smart battery balance system that includes a mobile computing device and a portable peripheral device, each with processors monitoring charge parameters, which dynamically adjust charging to ensure the mobile device's battery life is maintained longer than the peripheral's, by allowing the mobile device to charge the peripheral when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the peripheral device's battery is allowed to drain naturally, then the device operates independently without charging infrastructure, but the system uptime is reduced and energy is wasted when the peripheral runs out of charge while the mobile device still has power
Solution Approach 1:
The patent merges the battery systems of the mobile computing device and portable peripheral device by enabling bidirectional charging through their respective processors. The mobile device's processor monitors the peripheral's charge parameters and initiates charging when the peripheral's calculated empty time is less than the mobile device's, thereby combining their energy resources to maximize system uptime and prevent energy waste.
2Duration of action of moving object
If the mobile device charges the peripheral device, then the peripheral's battery life is extended, but the mobile device's battery is consumed faster
Solution Approach 1:
The mobile device's processor continuously monitors the peripheral device's charge parameters including battery level and consumption rate. This feedback mechanism allows the system to dynamically determine when charging is necessary (when calculated empty time of peripheral is less than mobile device) and adjust charging operations to optimize energy usage, extending peripheral battery life while managing mobile device energy consumption responsibly.
3Reliability
If dynamic charge monitoring and adjustment is implemented, then battery balance is optimized, but the system complexity increases due to additional monitoring and control mechanisms
Solution Approach 1:
The patent utilizes the existing processors in both the mobile computing device and portable peripheral device to perform multiple functions: their original computational tasks plus battery charge parameter monitoring and charging control. This multi-functionality approach optimizes battery balance without requiring separate dedicated monitoring hardware, thereby minimizing the increase in system complexity while achieving reliable battery balance.

AI summary
A smart battery power balance system and method to maximize the operating life of a mobile computing device and a portable peripheral (e.g., a peripheral having scanning capability). The mobile computing device battery and portable peripheral battery parameters such as battery level, velocity/rate of consumption and usage history are collected. A curve fitting and estimation is done to predict the empty time for complete battery discharge of the mobile computing device and portable peripheral. Based on this analysis, if the calculated empty time of the mobile computing device battery is less than the portable peripheral battery, the portable peripheral charges the mobile computing device battery and if the calculated empty time of the mobile computing device battery is greater than that of the portable peripheral battery, the portable peripheral battery does not charge the mobile computing battery.
