Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If electrical energy storage modules are connected in series circuit, then high charging voltage is achieved for fast charging stations, but the system cannot efficiently utilize household power connections with lower voltage
Solution Approach 1:
The patent implements dynamic reconfigurability of the electrical energy storage system by using switching elements to change the connection topology between modules based on the charging source. The system can dynamically switch between series connection (for high voltage fast charging) and parallel connection (for low voltage household charging), allowing optimal adaptation to different power sources and charging requirements
2Adaptability or versatility
If electrical energy storage modules are connected in parallel, then compatibility with household power connections is improved, but the system cannot efficiently charge using fast charging stations requiring high voltage
Solution Approach 1:
The switching elements enable the system to dynamically reconfigure from parallel connection (optimized for household charging) to series connection (optimized for fast charging) based on the detected power source characteristics, ensuring optimal performance for both charging scenarios
3Stability of the object's composition
If voltage balancing is performed by discharging high charge modules and charging low charge modules simultaneously, then state of charge balance is achieved, but additional control complexity and time are required
Solution Approach 1:
The patent combines the voltage balancing function with the existing switching element infrastructure by utilizing the same switching elements that manage series/parallel connections. During balancing mode, the switching elements reconfigure the module connections to enable controlled charge transfer between modules, merging multiple functions into a unified control architecture that reduces overall system complexity
Solution Approach 2:
The system performs self-balancing by internally redistributing charge between modules through the switching elements without requiring external intervention or additional balancing equipment. The control unit automatically manages the charge transfer process based on the state of charge of individual modules
