Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conventional energy station uses the input energy source to supply power to the load, then the energy station can provide power supply for outdoor operations, but the power supply to the load will be affected due to an imbalance between supply and demand
Solution Approach 1:
The patent implements a dynamic power balance mechanism where the central control module continuously monitors the power output of input energy sources and power consumption of loads, dynamically adjusting the working state of the switchable energy module between charging and discharging modes to maintain supply-demand balance and resolve the contradiction between power supply reliability and charging efficiency
Solution Approach 2:
The switchable energy module serves as an intermediary component between input energy sources and loads. It can switch between storing excess power from energy sources and releasing power to loads when demand exceeds supply, acting as a buffer that resolves the imbalance between power supply and demand to improve both reliability and efficiency
2Productivity
If the switchable energy module switches working state based on supply-demand relationship, then the power balance is improved, but the control complexity increases
Solution Approach 1:
The patent implements a feedback control mechanism where the central control module continuously monitors the power output of input energy sources and power consumption of loads, using this feedback information to dynamically adjust the working state of the switchable energy module. This automated feedback loop achieves power balance while managing control complexity through systematic monitoring and adjustment
3Speed
If multiple DC/DC charging modules are connected in parallel for fast charging, then the charging speed is improved, but the device complexity and power distribution difficulty increase
Solution Approach 1:
The patent divides the charging system into multiple independent DC/DC charging modules that can be connected in parallel. Each module operates independently but is coordinated by the central control module, which manages power distribution among parallel modules. This segmentation enables fast charging through parallel connections while managing complexity through modular design and centralized control

AI summary
The disclosure provides an energy station system, a control method of the energy station and an energy station. The energy station system includes at least one input energy source, at least one load, at least one central control module, and a switchable energy module. The switchable energy module switches its own working state based on a supply-demand relationship between the input energy source and the load, and the central control module controls the input energy source to supply power to the load. Through arranging the switchable energy module, it may be used to switch its working state according to the supply-demand relationship between the input energy source and 10 the load, so as to supplement the supply and demand imbalance between the input energy source and the load as characteristics of the input energy source or a DC load.
