Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If multiple charge ports are used simultaneously to recharge the battery, then charging time is reduced, but device complexity increases
Solution Approach 1:
The battery pack is divided into multiple independent modules, each with its own charge port. This segmentation allows parallel charging of different modules through multiple ports simultaneously, reducing overall charging time while keeping each individual module's charging circuit relatively simple.
Solution Approach 2:
The power management system is designed to universally handle multiple charging scenarios: single-port charging, multi-port parallel charging, and sequential charging. The same hardware infrastructure supports different charging modes, reducing the need for additional specialized components for each charging mode.
2Speed
If DC fast charging is implemented, then charging speed is improved, but cost and system complexity increase
Solution Approach 1:
The battery system is segmented into multiple modules that can be charged in parallel. Each module can receive DC fast charging independently, allowing the system to achieve high overall charging speed without requiring a single complex ultra-high-power charging circuit. The complexity is distributed across multiple simpler, standardized modules.
3Adaptability or versatility
If multiple charge ports are equipped, then charging flexibility is improved, but manufacturing cost increases
Solution Approach 1:
The battery pack is designed as modular segments, each with integrated charge ports. This modular segmentation allows manufacturers to produce standardized modules that can be assembled in different configurations, reducing overall manufacturing complexity and cost despite the presence of multiple charge ports in the complete system.
Solution Approach 2:
Instead of designing unique complex charging circuits for each port, the system uses replicated standardized charging modules. Each module contains a copy of the essential charging circuitry, allowing for mass production of identical units that can be combined in various configurations, significantly reducing per-unit manufacturing costs.

AI summary
A fast charging station, battery system and method for charging battery systems can be applied to most battery types in use for electric vehicles (EVs), electronic devices, and wireless electrical machines. The system provides for two or more charging ports in the electronic device, such as an EV, that may be able to receive and recognize a charging type, such as charging voltage, current and the like, and provide directed charging to multiple battery sub-packs that make up the entire battery. By charging sub-packs in parallel, the charge time can be substantially reduced. The system further provides a charging station with two or more electrical connections provided at each stall, providing for fast charge of an electrical device, such as an EV, positioned at each stall.
