Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current batch testing methods for charging piles are inefficient due to high power and load requirements, leading to increased device numbers, investment, and land occupation, with no effective solution to optimize detection efficiency.
Innovation Solution
A testing method and system that configures power supplies and loads in a time division manner, allowing multiple charging piles to execute test tasks in alternating periods, reducing total power and load demands by prioritizing tasks with lower power requirements, and utilizing a programmable power supply and load modules connected through a switch array.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all charging piles are tested simultaneously at full power, then testing completeness is improved, but total power consumption and device requirements increase extremely high
Solution Approach 1:
The patent implements periodic action by dividing the testing process into multiple time periods, where different charging piles are tested at different times. The controller schedules test tasks sequentially, allocating power supplies and loads to different charging piles in different time periods, thereby reducing peak power consumption while ensuring all charging piles receive comprehensive testing
Solution Approach 2:
The patent applies segmentation by dividing the test task set into multiple subsets corresponding to different time periods. Each subset contains test tasks that can be executed within the power constraints of that period. The controller segments the overall testing process into manageable phases, assigning different charging piles to different segments based on power availability
2Productivity
If the number of power supplies and loads is increased to match the number of charging piles, then testing parallelism is improved, but device investment and land occupation increase
Solution Approach 1:
The patent implements universality by designing power supplies and loads that can be dynamically allocated to serve multiple charging piles across different time periods. Instead of dedicating one power supply and one load per charging pile, the same power supplies and loads are reused sequentially for different charging piles, making each device multi-functional and reducing the total number of devices required
Solution Approach 2:
The patent merges the testing resources by consolidating multiple power supplies and loads into a shared pool that serves all charging piles. The controller manages the consolidation by dynamically assigning and reassigning these shared resources to different charging piles based on the testing schedule, thereby reducing device quantity while maintaining testing capability
3Quantity of substance
If power supplies and loads are reused after becoming idle, then device quantity is reduced, but detection efficiency decreases due to waiting time
Solution Approach 1:
The patent implements feedback mechanisms where the controller continuously monitors the status of power supplies and loads, detecting when they become idle. Based on this feedback, the controller automatically reassigns these idle resources to the next charging pile in the testing queue, minimizing waiting time and maintaining high detection efficiency while using fewer devices
Solution Approach 2:
The patent applies dynamics by making the allocation of power supplies and loads flexible and adaptive rather than static. The controller dynamically adjusts resource allocation based on real-time testing progress and idle status, enabling rapid reassignment of resources to maintain continuous testing flow and high efficiency despite using a reduced number of devices
