Wall Charging Station Mounting With CEE Plug-In Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wall charging stations require specialist installation and configuration, leading to high costs and safety risks when used with improper extension cables, and the infrastructure is not adaptable for non-specialist installation, posing challenges for widespread adoption and flexibility in charging infrastructure expansion.
Innovation Solution
A wall charging station design featuring a plug-in connection with a pre-installed standard-compliant CEE wall socket and an adapter device, along with a wall-mountable mounting device that allows for precise alignment and fixing, enabling non-specialist installation while maintaining safety standards, and incorporating data communication interfaces via wireless systems to decouple electrical and IT infrastructure setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wall-mounted charging station is installed by a specialist company, then safety and compliance with standards are ensured, but installation costs and complexity increase
Solution Approach 1:
The charging station system is divided into two separate parts: a wall socket with integrated differential voltage protection that can be installed by specialists, and a charging unit that can be independently mounted and configured by end users. This segmentation allows the safety-critical components to be pre-installed and certified, while the user-facing components remain simple to deploy
Solution Approach 2:
The wall socket with differential voltage protection is pre-installed and pre-configured by specialist companies during building infrastructure setup. This preliminary action ensures safety compliance is established beforehand, allowing end users to later simply mount the charging unit without needing to perform complex electrical installations or safety configurations
2Ease of manufacture
If electrical infrastructure and charging stations are installed simultaneously, then coordination is simplified, but unnecessary investment costs occur as not all users need charging stations immediately
Solution Approach 1:
The system separates the electrical infrastructure (wall socket with protection) from the charging station unit, allowing the infrastructure to be installed once for multiple potential users while the charging units are only deployed where and when needed. This enables phased investment rather than requiring complete installation for all locations simultaneously
Solution Approach 2:
The standardized wall socket with differential voltage protection serves as a universal base infrastructure that can support multiple different charging station units. This multi-functional design allows a single electrical infrastructure installation to serve numerous users over time, reducing the need for duplicate infrastructure investments
3Adaptability or versatility
If additional data interfaces and IT infrastructure are installed for smart wallboxes, then communication and load management capabilities are improved, but installation costs and complexity increase
Solution Approach 1:
The charging unit acts as an intermediary device that provides necessary communication interfaces and data processing capabilities without requiring complex centralized IT infrastructure. By distributing intelligence to the edge device (charging unit), the system achieves smart functionality while minimizing the need for elaborate backend IT systems
