Charging Pile as a 5G Multi-Hop Relay for Lower Network Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current charging piles primarily serve a single function of charging electric vehicles and lack advanced communication capabilities, such as 5G New Radio (5G NR) multi-hop relaying, which limits their network efficiency and power consumption.
Innovation Solution
Incorporating a central control module with a 5G communication module, a wireless local area network module, and memory, enabling the charging pile to receive and forward user information, act as a 5G NR multi-hop relay base station, and manage network connections, thereby reducing bandwidth and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a charging pile only has a single function of charging electric vehicles, then the device complexity is low, but the adaptability and versatility are insufficient
Solution Approach 1:
The charging pile is transformed into a multi-functional device by integrating 5G communication capabilities. The central control module now serves dual purposes: managing charging operations and handling 5G signal relay functions. This allows the charging pile to act as both a charging station and a 5G base station, improving versatility without requiring completely separate systems
2Productivity
If the charging pile acts as a 5G NR multi-hop relay base station, then the network efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent combines the charging pile and 5G base station functions into a single integrated device. The central control module handles both charging management and 5G signal processing, while shared components like power supply, housing, and location services support both functions. This merging reduces the need for separate infrastructure and optimizes resource utilization
3Loss of energy
If the charging pile uses 5G communication module for relay functions, then the bandwidth consumption is reduced, but the device complexity increases
Solution Approach 1:
The charging pile acts as an intermediary relay node in the 5G network architecture. It receives signals from source base stations and forwards them to user terminals or other charging piles, enabling multi-hop communication. This intermediary role distributes network traffic more efficiently and reduces the bandwidth burden on individual base stations

AI summary
A charging pile, including a central control module as well as a 5G communication module, a wireless local area network module and a memory which are connected to the central control module. The central control module receives, by the 5G communication module, a unicast request signal transmitted by a source base station; has a memory space reserved in the memory according to the unicast request signal, and transmits a ready-to-receive signal to the source base station by the 5G communication module; receives, by the 5G communication module, to-be-transmitted user information sent by the source base station, and stores it in the memory space in the memory; and forwards the to-be-transmitted user information to a user terminal or other charging piles by the 5G communication module, or forwards the to-be-transmitted user information to other charging piles by the wireless local area network module.
