Battery Replacement Matching by Current Rate and Deterioration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery replacement methods do not adequately consider the current rate usage environment, leading to suboptimal battery selection and potential 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, 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
1Power
If batteries are used at a high current rate, then power output is improved, but resistance value rises markedly causing performance deterioration
Solution Approach 1:
The system performs preliminary analysis of current rate history and capacity deterioration before battery replacement. By calculating the assumed greatest current rate in advance and comparing it with predetermined thresholds, the system selects an optimal replacement battery that prevents future performance deterioration, rather than waiting for actual failure to occur.
Solution Approach 2:
The system dynamically adjusts battery selection based on actual usage patterns. By continuously monitoring current rate history and calculating capacity deterioration, the system adapts its replacement strategy to match the specific operating environment, selecting batteries with appropriate current rate characteristics for the actual usage conditions.
2Temperature
If battery replacement is based only on temperature load, then thermal management is improved, but current rate compatibility is not ensured leading to suboptimal selection
Solution Approach 1:
The system expands the selection criteria from a single parameter (temperature load) to multiple parameters including current rate history, capacity, and capacity deterioration. By analyzing multiple parameters simultaneously, the system comprehensively evaluates both thermal management requirements and current rate compatibility, ensuring optimal battery replacement decisions.
3Device complexity
If an arbitrary battery is selected for replacement, then device complexity is reduced, but performance deterioration occurs due to mismatched current rate characteristics
Solution Approach 1:
The system enables batteries to serve themselves by automatically analyzing their own current rate history and capacity characteristics. The battery management system extracts usage patterns from historical data and uses this information to select the most suitable replacement battery, making the selection process intelligent and adaptive without requiring complex external intervention.

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.
