Battery Trade-in Value Setting Using Abnormal Usage Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery value setting apparatuses fail to accurately determine the trade-in value of batteries by not considering abnormal usage, leading to inappropriate pricing.
Innovation Solution
A battery value setting apparatus that includes an electronic control unit with a microprocessor and memory to acquire battery information, determine abnormal usage records, and set a trade-in value based on this information, adjusting the value when abnormal usage is detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the trade-in value is determined only based on battery state quantity (charge/discharge times, resistance, capacity), then the evaluation process is simple, but the trade-in value is inaccurate because abnormal usage is not considered
Solution Approach 1:
The system performs preliminary monitoring and recording of battery usage conditions during the battery's operational life. Usage information including abnormal conditions (such as overheating, overcharging, excessive current) are detected and stored in advance by the battery ECU, so that when trade-in evaluation is needed, the pre-collected usage data is already available for comprehensive assessment without requiring complex real-time analysis
Solution Approach 2:
The battery ECU serves as an intermediary device that collects usage information from the battery system and provides this data to the trade-in evaluation system. This intermediary component simplifies the overall evaluation process by pre-processing and organizing usage data, allowing the evaluation system to focus on analyzing the provided information rather than directly monitoring all battery parameters in real-time
2Measurement precision
If comprehensive battery usage information is collected to accurately determine trade-in value, then pricing accuracy improves, but information processing requirements increase
Solution Approach 1:
The system extracts only the essential usage information relevant to battery health and trade-in value from the complete set of battery operational data. The battery ECU identifies and extracts key parameters such as abnormal usage events, charge/discharge cycles, and environmental conditions, separating this critical information from other operational data that is not directly relevant to trade-in evaluation, thereby reducing information processing requirements while maintaining accuracy

AI summary
A battery value setting apparatus including an electronic control unit including a microprocessor and a memory connected to the microprocessor. The microprocessor is configured to perform, acquiring a battery information including an information on a usage record of a battery mounted on a predetermined object, determining whether there is an abnormal usage record of the battery based on the battery information, and setting a trade-in value of the battery when it is determined that there is the abnormal usage record lower than the trade-in value when it is determined that there is not the abnormal usage record.
