Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual-charging pile cooperative charging systems require high hardware updates and have limited applicability due to the need for pre-established communication connections between charging piles.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-established communication connections between charging piles are required, then charging coordination can be achieved, but hardware requirements increase and application scope is limited
Solution Approach 1:
The vehicle controller acts as an intermediary between multiple charging piles, receiving charging information from each pile independently and managing the charging coordination without requiring direct communication between the piles. This eliminates the need for complex pre-established communication connections between charging piles while maintaining reliable charging coordination.
Solution Approach 2:
Each charging pile independently provides charging information to the vehicle controller without needing to establish communication with other piles. The piles serve themselves by independently communicating with the vehicle, eliminating the need for inter-pile communication infrastructure and reducing hardware requirements.
2Productivity
If single charging pile is used, then hardware requirements are low, but charging efficiency and power delivery are limited
Solution Approach 1:
The charging system is segmented into multiple independent charging piles, each capable of providing charging information separately. The vehicle controller processes information from multiple segments (piles) simultaneously, enabling parallel charging operations that improve overall charging efficiency and power delivery without requiring complex integrated pile systems.
Solution Approach 2:
The vehicle controller is designed with multi-functionality to handle charging information from multiple independent piles simultaneously. It can manage single-pile charging, dual-pile charging, and coordinated charging scenarios, making the system universally applicable across different charging configurations without increasing pile hardware complexity.
3Adaptability or versatility
If communication conversion unit is always active, then communication compatibility is improved, but energy consumption and system complexity increase
Solution Approach 1:
The communication conversion unit dynamically adjusts its operation based on the detected communication protocols from charging piles. It activates only when protocol conversion is needed, switching between different communication protocols as required by the connected piles, thereby maintaining communication compatibility while minimizing unnecessary energy consumption from continuous operation.
Solution Approach 2:
The system uses feedback from the charging pile communication interfaces to determine when the communication conversion unit needs to be activated. The controller detects the communication protocol being used by each pile and activates the conversion unit only when protocol mismatch is detected, optimizing energy usage while maintaining compatibility across different communication standards.
