Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If charging piles work at full load, then charging power is sufficient, but grid capacity becomes insufficient and power quality deteriorates
Solution Approach 1:
The patent introduces an energy storage apparatus as an intermediary component between the charging pile and the grid. This energy storage system absorbs excess charging power during peak periods and releases stored energy when grid capacity is insufficient, thereby decoupling the direct relationship between charging load and grid stress. The energy storage apparatus acts as a buffer that mediates the contradiction between maintaining high charging power and preserving grid reliability.
Solution Approach 2:
The system performs preliminary charging actions by storing energy in advance during periods when grid capacity is adequate and power quality is good. The energy storage apparatus charges the battery of the electrical device during off-peak hours or when grid conditions are favorable, so that during peak demand periods, the charging can continue using pre-stored energy without overloading the grid.
2Productivity
If charging power is increased to meet user demand, then charging speed improves, but grid burden increases and power supply stability decreases
Solution Approach 1:
The energy storage apparatus serves as a mediator that enables high charging speed without directly increasing grid burden. By storing energy in advance and releasing it during high-demand periods, the system maintains fast charging capability while the energy storage buffer absorbs the fluctuations, preventing direct transmission of these demands to the grid and thus maintaining power supply stability.
Solution Approach 2:
The system performs preliminary energy storage actions during periods of lower demand to prepare for high-speed charging needs. The battery is charged in advance when grid conditions are favorable, enabling the charging pile to deliver high power output during peak user demand without proportionally increasing the instantaneous burden on the grid infrastructure.
3Loss of energy
If energy storage apparatuses are integrated to optimize energy utilization, then energy efficiency improves, but system complexity increases
Solution Approach 1:
The patent combines the charging pile and energy storage apparatus into an integrated system where the energy storage component is coupled with the charging infrastructure. This merging allows the system to simultaneously perform charging, energy storage, and grid interaction functions through a unified architecture, improving overall energy utilization efficiency by coordinating these functions while managing complexity through integration rather than separate independent systems.
Solution Approach 2:
The integrated system is designed to perform multiple functions: it can charge electrical devices, store excess energy, release energy during peak demand, and interact with the grid. By making the charging pile system universal and multi-functional, the patent achieves improved energy utilization through a single system that adapts to different operational modes rather than requiring separate specialized systems for each function.
