Battery Voltage Determination Unit for Standby Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in determining the state or residual quantity of a battery in electronic devices without turning on the device or booting it, especially when the device is in an off, standby, or sleep mode.
Innovation Solution
An electronic apparatus is designed with a battery voltage determination unit connected in parallel to the processor, allowing it to operate independently and output battery information without powering on the device, using a communication processor to determine battery state even in sleep mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the electronic apparatus is turned on or booted to confirm battery state, then battery information can be obtained, but power consumption increases and device startup time is required
Solution Approach 1:
The system is divided into two independent parts: the application processor (AP) that can be in sleep mode, and the battery voltage determination unit that operates independently with its own power supply from the battery. This segmentation allows battery monitoring without activating the main processor, reducing power consumption while maintaining information availability.
Solution Approach 2:
A separate battery voltage determination unit acts as an intermediary between the battery and the application processor. This intermediate component can determine battery voltage and output control signals without requiring the AP to be active, enabling battery state confirmation while the AP remains in sleep mode.
2Measurement precision
If the application processor operates to determine battery voltage, then accurate battery information is obtained, but the device cannot remain in sleep mode
Solution Approach 1:
The monitoring function is segmented from the main processor into an independent battery voltage determination unit. This unit can operate with minimal power consumption while the AP remains in sleep mode, allowing extended sleep duration without sacrificing measurement capability.
Solution Approach 2:
The battery voltage determination unit performs self-service by autonomously monitoring battery voltage and generating control signals without requiring the application processor to be active. This self-contained operation enables accurate battery information while maintaining sleep mode.
3Loss of information
If the device is powered on to check battery state, then complete battery information is available, but user convenience decreases due to required device activation
Solution Approach 1:
The battery information output unit serves as an intermediary that provides battery state information through external indicators without requiring the main device to be powered on. This mediator function enables users to check battery residual quantity conveniently while the device remains off.
Solution Approach 2:
The system replaces the mechanical requirement of powering on the device with an electrical/optical indication system. Battery voltage determination triggers control signals that can activate external indicators (such as LEDs or display elements) without requiring full device startup, substituting the mechanical action with a more convenient electrical indication.
