Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and complexity of replacing and repairing large lithium-ion batteries in electric vehicles hinder their widespread adoption due to the lack of effective battery life tracking and management systems.
Innovation Solution
A vehicle battery life tracking system comprising a vehicle battery with individual units, an electronic control unit, and a wireless communication unit that monitors and stores chargeability information, uploading it to external memory storage upon predetermined incidents, utilizing a blockchain ledger for secure and transparent data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery replacement and repair systems are implemented, then battery reliability is improved, but device complexity and cost increase
Solution Approach 1:
The system performs preliminary actions by continuously monitoring and storing chargeability information throughout the battery's operational life. Data is collected and preserved in memory before any replacement or repair is needed, enabling informed decision-making and targeted interventions rather than reactive replacements.
Solution Approach 2:
The system implements feedback mechanisms by uploading chargeability information to external databases and providing access to stakeholders. This feedback loop enables continuous improvement of battery management strategies, optimization of replacement timing, and reduction of unnecessary replacements based on actual performance data.
2Loss of information
If comprehensive battery monitoring is implemented, then loss of information is reduced, but device complexity increases
Solution Approach 1:
The system extracts and isolates the data management complexity from the battery itself by storing chargeability information in the battery's memory and enabling upload to external databases. This separation allows the battery to remain relatively simple while comprehensive monitoring capabilities are achieved through the external infrastructure.
Solution Approach 2:
The wireless communication unit and external database serve as intermediaries between the battery and stakeholders. Rather than requiring complex direct monitoring interfaces for all users, the system uses these intermediary components to store, manage, and distribute battery information efficiently.
