Battery Temperature Monitoring During Non-Use Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric working machines and electric vehicles' batteries face temperature-related degradation due to outdoor usage, and existing systems lack effective monitoring for battery temperature management during non-use periods, leading to potential battery deterioration.
Innovation Solution
A temperature monitoring device that acquires and analyzes battery temperature data during non-use periods to determine if it falls within a predetermined safe range, excluding an initial period for accurate determination, prompting users to maintain appropriate storage conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the temperature monitoring device monitors battery temperature continuously from the starting time of non-usage, then it can provide comprehensive temperature data, but it includes inaccurate initial temperature data that does not reflect the actual storage temperature conditions
Solution Approach 1:
The determination processing unit excludes the initial period from the starting time of non-usage, performing preliminary filtering of temperature data before evaluation. This preliminary action removes inaccurate temperature readings that occur during the transition phase, ensuring that only stable, representative temperature data is used for determining whether the battery is stored in an appropriate temperature environment.
2Loss of information
If the system evaluates temperature data including the initial period, then it can maximize data utilization, but it reduces user awareness of actual temperature management issues
Solution Approach 1:
Instead of evaluating all available temperature data including the initial period, the system inverts the approach by deliberately excluding the initial period from evaluation. This inversion focuses attention on the stable temperature phase that truly reflects storage conditions, making temperature management feedback more meaningful and actionable for users.
3Measurement precision
If the determination processing unit excludes the initial period, then it achieves accurate temperature assessment, but it requires additional logic to determine when the initial period ends
Solution Approach 1:
The determination processing unit autonomously determines when the initial period ends by monitoring temperature data characteristics. The system self-services by automatically identifying the transition from unstable initial temperature readings to stable storage temperature readings, eliminating the need for external intervention or complex manual configuration while maintaining accurate temperature assessment.
Data Source
AI summary
A management server, which is a temperature-monitoring device, monitors the temperature of a battery that is removably attached to an apparatus. The management server includes: a server-side acquisition unit that acquires the temperature of the battery when the battery is not in use after discharging electricity to the apparatus; and a determination process unit that performs a temperature determination process for determining whether or not the temperature while the battery is not in use is in a predetermined temperature range. The determination process unit excludes, from items on which the temperature determination process is to be performed, the temperature during an initial period from when the non-use of the battery has started to when a predetermined condition is satisfied.
