Modular EV Charging Skid for Fast On-Site Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional site installation of ground mount electric vehicle (EV) chargers is expensive, permanent, and labor-intensive, with adverse weather and environmental conditions complicating the process due to on-site work requirements.
Innovation Solution
A modular, easy-to-install EV charging skid system that can be manufactured in a factory and assembled on-site with minimal field work, featuring a pre-cast concrete skid base, power and panel cabinets, and a cable raceway system to accommodate various charger designs and orientations, reducing the need for custom installations and minimizing worker hours.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional site installation methods are used for ground mount EV chargers, then the installation is permanent and stable, but the process is expensive, labor-intensive, and requires significant worker hours from multiple trades
Solution Approach 1:
The charging station system is divided into modular components (EV charger, power cabinet, panel cabinet, skid base) that can be manufactured separately and assembled on-site. This segmentation allows factory production of complex components while simplifying field installation to basic assembly tasks, resolving the contradiction between installation stability and installation efficiency.
2Reliability
If traditional site installation methods are used, then the charger is permanently installed, but adverse weather and environmental conditions complicate the installation work
Solution Approach 1:
Complex components (EV charger, power cabinet, panel cabinet) are pre-assembled and pre-tested in controlled factory conditions before shipping to the installation site. This preliminary action removes the most weather-sensitive work from the field, allowing only simple skid placement and cable connections to be performed outdoors, thus resolving the contradiction between installation permanence and weather resistance.
3Adaptability or versatility
If custom installations are performed on-site, then the charger accommodates specific site requirements, but the complexity and duration of installation increases
Solution Approach 1:
The skid base is designed as a universal platform with standardized mounting interfaces and cable access points that can accommodate different EV charger models and configurations. This universality allows the same basic skid structure to serve multiple site requirements without requiring custom fabrication, resolving the contradiction between site customization and installation complexity.
