Solution Overview
Problem
Traditional battery systems for vehicles, such as motorcycles, often have unknown charge levels when purchased, leading to potential failure upon installation, and require cumbersome lead cable connections for charging, necessitating a solution for monitoring and managing battery state of charge and safety.
Innovation Solution
A battery management system with integrated sensors and processing circuitry that monitors voltage, temperature, and current, provides state of charge indicators, and controls charging to prevent over-discharge, over-voltage, and overheating, allowing for easy monitoring and charging without direct access to battery terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional battery systems are used without integrated management, then device complexity is reduced, but reliability deteriorates due to unknown charge levels and potential failure upon installation
Solution Approach 1:
The patent combines the battery management system, including control circuitry, sensors, and communication interfaces, directly into the battery housing. This integration ensures the battery can self-monitor its charge level, temperature, and health status, eliminating the reliability issues of traditional separate systems while consolidating components into a unified structure.
Solution Approach 2:
The battery management system performs preliminary monitoring and assessment of the battery's charge level and operational status before the battery is installed or used. This allows the system to detect potential failures in advance and provide warnings or adjustments, preventing reliability issues before they occur.
2Ease of operation
If lead cable connections are required for charging, then charging functionality is achieved, but ease of operation deteriorates due to cumbersome connections
Solution Approach 1:
The patent replaces the mechanical lead cable connection system with an integrated communication interface and wireless or direct electrical connection system. The control circuitry within the battery manages charging parameters and communicates with external charging devices, eliminating the need for manual lead cable connections and significantly improving ease of operation.
3Measurement precision
If integrated sensors and processing circuitry are added, then measurement precision improves for monitoring voltage, temperature, and current, but device complexity increases
Solution Approach 1:
The patent integrates multiple sensors (voltage, temperature, current) and processing circuitry into a single unified battery management system within the battery housing. This consolidation improves measurement precision by coordinating multiple sensors under centralized control while minimizing the increase in overall device complexity through shared power supply, signal processing, and communication interfaces.
