Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If battery data communication between portable devices and power storage adapters is implemented using existing systems, then basic power transfer can occur, but efficient battery data communication and management is lacking
Solution Approach 1:
The patent introduces a battery management unit (BMU) as an intermediary component within the power storage adapter that specifically handles battery data communication. The BMU receives battery data from the portable device, processes it, and communicates with the power storage adapter's controller, thereby improving battery data communication efficiency without requiring complete system redesign.
Solution Approach 2:
The system is segmented into distinct functional components: the portable device's battery, the power storage adapter's battery, the BMU for data management, and the controller for power management. This segmentation allows specialized handling of battery data communication through the BMU while keeping the overall system architecture manageable and modular.
2Reliability
If comprehensive battery parameters are collected and communicated, then battery operation and capacity prediction can be improved, but data processing requirements increase
Solution Approach 1:
The patent extracts and identifies specific critical battery parameters that need to be communicated, such as charge state, discharge state, temperature, and capacity information. By selectively extracting only the essential parameters rather than all possible battery data, the system improves battery operation reliability while managing data processing requirements effectively.
3Measurement precision
If real-time battery measurements are implemented using sensors, then battery capacity prediction accuracy improves, but device complexity increases
Solution Approach 1:
The battery management unit serves multiple functions: it collects data from sensors, processes battery parameters, manages communication between the portable device and power storage adapter, and supports capacity prediction. This multi-functionality reduces the need for separate dedicated components, thereby improving measurement precision without proportionally increasing device complexity.

AI summary
A power storage adapter coupled to a portable information handling system using a variable power bus may receive first battery data from an embedded controller of the portable information handling system. The first battery data may be used by a battery management unit in the power storage adapter for power management of a battery. The power storage adapter may also collect second battery data from other portable information handling systems and send the second battery data back to the embedded controller.
