1Productivity
If conventional batteries are used without logic and communication capabilities, then device complexity is reduced, but charging efficiency and monitoring accuracy deteriorate
Solution Approach 1:
The patent combines the battery with integrated logic and communication capabilities into a unified smart battery system. The measurement module, communication interface, and battery components are merged into a single integrated unit that can autonomously monitor electrical characteristics, predict battery life, and communicate with external devices, thereby improving charging efficiency without requiring separate monitoring systems.
Solution Approach 2:
The smart battery performs self-monitoring of its electrical characteristics through the integrated measurement module, which continuously tracks voltage, current, and temperature. The battery autonomously predicts its own life cycle and communicates charging status without external intervention, enabling self-service functionality that improves charging efficiency while maintaining manageable complexity.
2Measurement precision
If smart batteries with measurement modules are integrated, then battery life prediction accuracy is improved, but device complexity increases
Solution Approach 1:
The measurement module is merged directly into the battery structure, combining sensing elements for voltage, current, and temperature measurement with the battery cells themselves. This integration allows accurate battery life prediction through continuous monitoring of electrical characteristics without requiring separate external monitoring equipment, thereby improving measurement precision while containing complexity within the battery unit.
Solution Approach 2:
The smart battery implements feedback mechanisms where the measurement module continuously monitors electrical characteristics and feeds this data to prediction algorithms. The communication interface provides feedback to external devices about battery status and predicted life, enabling accurate battery life prediction through closed-loop monitoring and data analysis.
3Ease of operation
If wireless charging is implemented, then device portability and ease of operation are improved, but energy transfer efficiency deteriorates
Solution Approach 1:
The patent replaces mechanical wired charging connections with wireless electromagnetic induction-based charging. The transmit charging coil and receive charging coil enable contactless power transfer, eliminating the need for physical plugging and unplugging of charging cables, thereby significantly improving charging convenience and ease of operation.
Solution Approach 2:
The wireless charging system employs periodic detection and adjustment of charging parameters. The measurement module periodically monitors charging status and the system adjusts power transfer levels accordingly, optimizing energy transfer efficiency during wireless charging operations while maintaining the convenience of contactless charging.
