Rectangular Charging Pole for Thick-Cable EV Charger Chaining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging infrastructure in Nordic countries is inadequate for modern electric vehicle (EV) charging needs, as traditional heating poles are not designed to accommodate thicker cables required by newer EV chargers, and the infrastructure is often manufacturer-specific, leading to high costs and inefficiencies.
Innovation Solution
A new charging pole system with a rectangular cross-section and hollow interior, capable of accommodating two cables with a cross-sectional area of 50mm², along with a connection housing for chaining cabling and a ground-rooted base for stability, allowing for flexible installation of various EV chargers and enabling separate installation of cabling and chargers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional heating poles with 60mm diameter are used, then the infrastructure can accommodate Schuko socket outlets for pre-heating combustion engine cars, but the poles cannot accommodate thicker cables required by larger groups of parking spaces and for the required power
Solution Approach 1:
The pole diameter is increased from the traditional 60mm to at least 75mm (with embodiments specifying 75mm, 90mm, or 100mm), enabling the pole to accommodate thicker cables with larger cross-sectional areas required for higher power transmission to multiple parking spaces
2Strength
If traditional heating poles are used, then the infrastructure is already in place for pre-heating, but the foundations are not strong enough for charging devices which are significantly heavier and larger than today's heating boxes
Solution Approach 1:
The foundation is designed and constructed in advance with sufficient strength to support future charging devices, even though the poles currently only need to support lighter heating boxes. This preliminary strengthening ensures that when charging devices are installed later, the foundation can bear their significantly heavier weight without requiring foundation reconstruction
3Ease of operation
If charging devices are placed higher to avoid snow accumulation and improve usability, then the devices are more accessible and protected from snow, but the pole must accommodate both the elevated mounting position and thicker cables
Solution Approach 1:
The pole cross-sectional area is increased to at least 75mm diameter, providing sufficient internal space to accommodate thicker cables while also supporting the charging device at an elevated position that avoids snow accumulation and improves user accessibility
4Reliability
If manufacturer-specific mounting stands are used for each EV charger, then the charging device can be mounted securely, but the system lacks general-purpose chaining/serial pre-connected charging readiness cabling without charging devices
Solution Approach 1:
The pole is designed as a universal mounting structure with standardized features that can accommodate charging devices from different manufacturers. The pole includes pre-installed cable glands and mounting brackets that work with various EV charger types, enabling general-purpose chaining and serial connection of charging readiness cabling independent of specific charging device manufacturers
5Power
If a pole is designed to accommodate thicker cables for multiple parking spaces, then the power capacity is sufficient, but the pole becomes larger and may require more installation space
Solution Approach 1:
The pole is constructed using composite or optimized materials that provide high structural strength and cable accommodation capacity with a relatively compact cross-section. This allows the pole to handle thick cables for multiple parking spaces while minimizing the pole's overall footprint and installation space requirements
