Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If auxiliary units are used to generate alternating current and manage battery packs, then voltage control and motor operation are enabled, but system complexity and cost increase
Solution Approach 1:
The patent combines the functions of auxiliary units, voltage management, and battery control into the battery cell itself through integrated circuitry. The smart battery cell incorporates DC-DC conversion capability and control electronics directly within the cell structure, eliminating the need for separate auxiliary units and reducing overall system complexity while maintaining voltage control capability.
Solution Approach 2:
The smart battery cell is designed to perform multiple functions: energy storage, voltage regulation, DC-DC conversion, and system control. By making the battery cell universal and multi-functional, the patent eliminates the need for dedicated auxiliary units, thereby reducing system complexity and cost while maintaining adaptability for different voltage requirements.
2Stability of the object's composition
If battery packs provide constant voltage, then voltage stability is maintained, but the ability to provide fluctuating voltage and AC output is lost
Solution Approach 1:
The smart battery cell incorporates dynamic voltage regulation capability through integrated DC-DC conversion circuitry. This allows the cell to maintain stable voltage under normal conditions while dynamically adjusting to provide fluctuating voltage and AC output when required, resolving the contradiction between voltage stability and adaptability.
3Reliability
If existing battery management systems are used, then basic monitoring is provided, but integrated monitoring and switch functionality is lacking
Solution Approach 1:
The patent integrates monitoring sensors, control logic, and switch functionality directly into the battery cell structure. This high level of integration improves reliability by providing comprehensive monitoring while reducing the need for separate management systems and external components, thereby actually reducing overall system complexity despite the increased integration within the cell.

AI summary
Systems, devices, computer-implemented methods, and/or computer program products that can facilitate an intelligent battery cell are addressed. In one example, a device can comprise: active battery cell material; and an internal circuit coupled to the active battery cell material and comprising: a circuit board; two alternating current (AC) power points; two isolated direct current (DC) power points; and a controller that can operate one or more switches on an H-bridge circuit to disconnect the device from a main battery in a bypass mode. In another example, a smart cell modulator can comprise: a set of smart battery cells; and a controller that can operate to selectively engage a subset of the smart battery cells to enable load sharing, distributed feedback control, circulate load across one or more smart battery cells of the set of smart battery cells to increase torque, and to enable speed requests.
