Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a traditional single-link charging system is used to simplify the network structure, then the device complexity is reduced, but the reliability deteriorates because a communication fault in any charging unit causes the entire system to fail
Solution Approach 1:
The charging system is segmented into multiple independent charging units (first charging unit, second charging unit) that can operate autonomously. Each charging unit has its own communication capabilities, allowing the system to function even when individual units experience communication faults. This segmentation enables the system to maintain reliability while managing complexity through modular design.
Solution Approach 2:
The patent introduces a dual communication path dimension: direct communication between charging units and cloud platform communication. This multi-dimensional communication architecture allows charging operations to proceed through alternative paths when one communication link fails, thereby improving reliability without significantly increasing overall system complexity.
2Device complexity
If the charging system connects to the cloud platform through a single link to simplify communication, then the device complexity is reduced, but the reliability deteriorates because communication outages prevent charging settlement and lead to charging failures
Solution Approach 1:
The patent introduces intermediary charging units that can relay communication and control information between the cloud platform and target vehicles when direct communication paths are unavailable. These intermediary units act as mediators, ensuring that charging settlement and control functions remain reliable even when cloud platform communication is interrupted.
Solution Approach 2:
The system performs preliminary actions by establishing multiple communication paths and designating backup charging units before communication faults occur. When a communication outage happens, the pre-configured alternative paths and standby units are already in place to immediately take over, ensuring uninterrupted charging settlement and operation.
3Reliability
If multiple parallel charging units are deployed to improve system reliability, then the reliability is improved, but the device complexity increases due to more complex network transmission and conversion requirements
Solution Approach 1:
Each charging unit is designed with universal communication capabilities that allow it to perform multiple functions: direct vehicle charging, cloud platform communication, and relaying information for other units. This multi-functionality reduces the need for specialized complex transmission equipment for each unit, thereby improving reliability through redundancy while controlling overall network transmission complexity.

AI summary
The present disclosure discloses a charging control method and system, and a storage medium. The charging control method is applied in a charging control system including a pile cloud platform, a charging pile system, and a vehicle cloud platform interacting with the pile cloud platform through a first communication connection. The method includes: when a communication fault occurs in the charging pile system, generating, based on charging control information to be transmitted, target route information by a first charging unit where the communication fault occurs; and transmitting the target route information to the target vehicle through the first communication connection and the second communication connection, and completing, by the target vehicle, a charging operation on the target vehicle based on the charging control information in the target route information received by the charging pile system. According to the present disclosure, the charging operation on the vehicle is realized when the fault occurs in the charging pile system, thereby enhancing robustness of the charging system.
