Battery Cool-Down Status Indication via Color-Coded Lights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Random selection of charged batteries from a battery room can lead to reduced battery life and performance due to inadequate post-charge cool-down time, as users may not identify batteries that have undergone the maximum cooling period.
Innovation Solution
A system and method utilizing a user display with lights to indicate the cool-down status of batteries, transitioning from a red light during charging completion to yellow after 4 hours and green after 6 hours, signaling readiness for use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If batteries are randomly selected from the battery room, then battery availability for use is improved, but battery life and performance deteriorate due to inadequate cool-down time
Solution Approach 1:
The patent uses color-coded lights (red, yellow, green) on battery indicators to communicate cool-down status. Red indicates charging in progress, yellow indicates cool-down in progress, and green indicates ready for use. This visual signaling system allows users to quickly identify batteries that have completed the required cool-down period without random selection, thereby maintaining both availability and battery life.
2Loss of time
If charged batteries are selected without monitoring cool-down status, then selection speed is improved, but battery performance deteriorates
Solution Approach 1:
The battery system provides self-service information through automatic status indicators that require no user intervention to read. The lights automatically display the cool-down status based on internal timing and temperature monitoring, allowing users to make informed selections quickly without needing to ask for or interpret additional information.
Solution Approach 2:
The color-coded lighting system provides immediate visual feedback about battery readiness. Users can instantly identify green-indicated batteries as ready for use, eliminating the need for random selection or time-consuming status checks while ensuring optimal cool-down has occurred.
3Reliability
If post-charge cool-down time is extended to maximize battery life, then battery life is improved, but battery availability deteriorates
Solution Approach 1:
The system implements feedback through automatic status indicators that communicate real-time cool-down progress to users. The lights transition from red (charging) to yellow (cooling) to green (ready), providing continuous feedback about battery status. This allows the system to maintain optimal cool-down durations while maximizing availability by clearly indicating when batteries are ready for use.
Solution Approach 2:
The system begins the cool-down process automatically as soon as charging completes, without waiting for user intervention. The timing mechanism starts immediately and the status indicators reflect this preliminary action, ensuring maximum battery life protection while preparing batteries for use as quickly as possible.

AI summary
A method for cooling a battery after a charging phase including the steps of providing a user display, identifying a starting point at which the charging phase of the battery transitions to a cooling phase, when the starting point is identified, instructing the user display to provide a first indication for a first predetermined amount of time, and after the first predetermined amount of time has elapsed, instructing the user display to provide a second indication.
