Charging Station Connection Rails Modular Power Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional charging stations for electric vehicles require complex and costly cabling for multiple charging points, leading to increased assembly and maintenance efforts, as each station needs a direct connection to the power supply network, limiting scalability and flexibility.
Innovation Solution
The implementation of connection rails within the charging station housing allows for a sub-distribution line to serve as a power supply for multiple stations, reducing direct connections and enabling a modular, expandable infrastructure with simplified cabling and maintenance access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each charging station is directly connected to the power supply network via its own power supply line, then each station can operate independently and reliably, but the cabling complexity and assembly effort increase significantly
Solution Approach 1:
The patent merges multiple power supply lines into a common power supply line that serves multiple charging stations. The power supply line connects to a common connection rail system that distributes power to multiple plug-in elements, reducing the number of separate cables and connections needed while maintaining reliable power supply to each charging station.
Solution Approach 2:
The common power supply line and connection rail system serve multiple functions: they provide power to multiple charging stations simultaneously, enable easy connection and disconnection of individual stations, and allow for scalable expansion of the charging infrastructure without requiring separate power lines for each station.
2Productivity
If multiple plug-in elements are provided in a common housing for simultaneous charging of multiple vehicles, then charging capacity increases, but the cabling and connection complexity increases
Solution Approach 1:
The charging station is segmented into multiple independent plug-in elements, each with its own charging cable and connection interface. This allows each plug-in element to be independently connected to vehicles while sharing a common power supply and control system, reducing overall connection complexity while maintaining high charging capacity.
Solution Approach 2:
The connection rail system acts as an intermediary between the common power supply line and the multiple plug-in elements. It simplifies the connection architecture by providing a standardized interface that distributes power to multiple plug-in elements without requiring complex individual wiring for each element.
3Ease of manufacture
If conventional cabling methods are used for multiple charging stations, then each station can be installed separately, but the assembly effort and maintenance difficulty increase
Solution Approach 1:
The connection rails and power distribution system are pre-configured and pre-assembled within the housing before the charging stations are installed. This preliminary preparation simplifies on-site assembly and reduces the complexity of connecting multiple stations, as the internal wiring and connection points are already in place and ready for plug-in element attachment.
