Modular EV Charger Pedestal Base for Above-Ground Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high deployment costs and complexity of electric vehicle (EV) charger systems are exacerbated by the need for individually manufactured pedestal bases compatible with specific EV chargers, leading to increased installation times and costs due to unique mechanical interfaces and extensive site preparation.
Innovation Solution
A universal pedestal base with modular components, including a skid base and multiple covers with different mechanical interfaces, allows for standardized wiring configurations and the ability to interface with various EV chargers, reducing deployment costs and enabling above-ground installation with a cable management system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individually manufactured pedestal bases with unique mechanical interfaces are used for each EV charger, then compatibility with specific EV chargers is improved, but deployment costs and installation complexity increase
Solution Approach 1:
The pedestal base is designed with a universal mechanical interface that can accommodate multiple EV charger models. The interface includes standardized mounting features and cable management openings that work with different charger types, eliminating the need for custom-made bases for each charger model while reducing installation complexity
2Adaptability or versatility
If individually manufactured pedestal bases are used for each EV charger, then compatibility with specific EV chargers is improved, but deployment costs increase
Solution Approach 1:
A single universal pedestal base design can serve multiple EV charger models, allowing for standardized manufacturing processes and bulk production. This eliminates the need for individual customization for each charger model, significantly reducing manufacturing costs while maintaining compatibility through the universal interface design
Solution Approach 2:
The pedestal base is designed as a modular unit with separate functional components (mounting interface, cable management system, protective housing) that can be manufactured independently and assembled. This segmentation enables standardized production of each module, reducing overall manufacturing costs while maintaining adaptability through configurable assembly
3Reliability
If extensive site preparation is performed for each EV charger installation, then proper installation foundation is improved, but installation times increase
Solution Approach 1:
The pedestal base incorporates pre-assembled cable management systems and pre-configured mounting interfaces that are prepared during manufacturing. This preliminary preparation eliminates the need for extensive on-site customization and preparation work, allowing for rapid installation while maintaining a solid, reliable foundation through the pre-engineered base structure

AI summary
A pedestal base may include a skid base and a cover. The skid base may define an opening. The skid base may interface with a cable management system (CMS) via the opening. The cover may mechanically interface with an electric vehicle (EV) charger. The cover may also mechanically interface with the skid base. The skid base and the cover may define a volume. The skid base and the cover, when mechanically interfaced, may permit a cable to extend between the CMS and the EV charger and to extend through the opening and the volume.
