Battery Replacement Selection Using Current Rate History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery management systems fail to ensure optimal battery replacement by not considering the current rate of battery usage, leading to accelerated performance deterioration.
Innovation Solution
A battery management system that calculates the assumed greatest current rate of candidate batteries based on the current rate history and capacity of the installed battery, taking into account the amount of deterioration, to select a replacement battery with a current rate no greater than a predetermined rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If battery replacement is based only on temperature load consideration, then replacement process is simple, but the replaced battery may not be optimal for the user's operating environment
Solution Approach 1:
The system performs preliminary analysis of the user's current rate history and operating environment before battery replacement. By calculating the assumed greatest current rate based on historical data and predicting future usage patterns, the system prepares optimal replacement criteria in advance, ensuring the replaced battery matches the user's actual operating conditions without making the replacement process complex
Solution Approach 2:
The system uses feedback from the installed battery's current rate history and operating environment data to continuously refine replacement decisions. By monitoring actual usage patterns and comparing them with candidate battery specifications, the system adjusts replacement criteria to ensure optimal performance matching, transforming a simple temperature-based replacement into an intelligent, data-driven process
2Quantity of substance
If a battery with high capacity is selected for replacement, then energy storage is improved, but the assumed greatest current rate may exceed the predetermined current rate causing accelerated deterioration
Solution Approach 1:
The system changes the selection parameters for battery replacement by calculating the assumed greatest current rate based on the user's historical usage patterns and operating environment. Instead of selecting batteries based solely on capacity or temperature ratings, the system transforms the selection criteria to include current rate compatibility, ensuring that high-capacity batteries are only chosen if their assumed greatest current rate remains within the predetermined threshold that prevents accelerated deterioration

AI summary
A battery management system includes an arithmetic processing unit that selects a replacement battery from among a plurality of candidate batteries, to replace an installed battery that is installed in equipment. The arithmetic processing unit calculates an assumed greatest current rate of each of the candidate batteries when used in the equipment, from current rate history of the installed battery and capacity of the candidate battery taking into consideration an amount of deterioration of the candidate battery. The arithmetic processing unit selects a battery of which the assumed greatest current rate of each of the candidate batteries that is calculated is no greater than a predetermined current rate, from among the candidate batteries as the replacement battery.
