Battery Charge Rate Detection via Display Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in accurately determining the real-time charge or discharge rate of a device's battery, especially when using the device and running applications, as existing methods require closing applications to view battery data, leading to inaccurate readings due to changes in resource consumption.
Innovation Solution
A device with a processor and memory that detects battery charge and discharge rates and actuates the display or a light to indicate these rates without user input, allowing for real-time monitoring and indication of battery status without closing applications or opening battery-related apps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user closes applications to view battery data in a battery-related application, then the battery charge or discharge rate measurement can be obtained, but the measurement becomes inaccurate over time due to changes in resource consumption when applications are opened and closed
Solution Approach 1:
The system performs preliminary actions by continuously monitoring battery charge and discharge rates in the background before the user needs to view the data. The processor detects the rate of charge or discharge of the battery and stores this information ready for immediate display, eliminating the need to close applications first and ensuring the measurement is current and accurate when the user views it.
2Reliability
If the device displays battery charging status based on engagement with a charge source, then the user can see charging indication, but the indication may be inaccurate when the user manipulates the device and consumes power
Solution Approach 1:
The system implements feedback by continuously monitoring both the charge source engagement status and the actual battery charge/discharge rates, then comparing this data to provide an accurate real-time indication. The processor detects the rate of charge or discharge and uses this feedback to update the display, ensuring the charging status reflects the actual battery state rather than just the charge source connection status.
3Loss of information
If the system requires user input to detect and present battery charge or discharge rate information, then the user can control when data is displayed, but the user cannot obtain accurate real-time battery status while using the device
Solution Approach 1:
The system performs self-service by automatically detecting the battery charge and discharge rates without requiring user input. The processor continuously monitors the battery status and automatically updates the display with the current charge or discharge rate information, making the battery status information readily available while the user uses the device for other purposes.
Data Source
AI summary
In one aspect, a device includes a battery, a display, a processor, and a memory accessible to the processor. The memory bears instructions executable by the processor to detect a rate of charge of the battery or a rate of discharge of the battery and, based at least in part on the detected rate, actuate at least one of the display and a light on the device other than the display to indicate the detected rate. The display and/or light are actuated based on the detected rate without user input to actuate the display or the light to indicate the detected rate, and without user input to detect or determine the rate of charge of the battery or discharge of the battery.
