EV Charger Pre-Configuration for Faster Secure Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for on-site installation and setup of electric vehicle (EV) charging equipment, particularly 'smart' EVSEs, are complex and time-consuming, requiring specialized technicians and involving multiple configuration steps.
Innovation Solution
A method that involves defining identification and configuration information for EV charging equipment before installation, uploading this information to both the equipment and the back-end system, and using a public key for secure communication, thereby simplifying the on-site installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex on-site configuration steps are performed with specialized technicians, then proper setup and network configuration is achieved, but installation time and cost increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring identification information (serial numbers, certificates, public/private key pairs) and connectivity settings during the manufacturing process. This allows the EVSE to be delivered in a pre-configured state, eliminating the need for complex on-site configuration steps and specialized technician intervention for setup, while ensuring proper configuration is achieved.
2Ease of operation
If pre-configuration is performed during manufacturing, then on-site installation is simplified, but manufacturing process complexity increases
Solution Approach 1:
The patent performs identification information generation and configuration uploads during manufacturing, including creating serial numbers, security certificates, and key pairs. This preliminary action simplifies on-site installation to basic tasks like connecting power and network, while the manufacturing process complexity is managed through automated systems that can efficiently handle the configuration tasks.
3Loss of time
If identification information is uploaded before installation, then on-site setup time is reduced, but risk of information loss or error increases
Solution Approach 1:
The patent implements feedback mechanisms including automated verification of uploaded identification information, integrity checks for certificates and key pairs, and error detection protocols during the pre-installation configuration phase. This ensures configuration accuracy is maintained while still achieving time savings by performing setup before installation.
4Reliability
If specialized technicians are required for configuration, then proper system setup is ensured, but installation cost increases
Solution Approach 1:
The patent performs all complex configuration tasks including network settings, identification information generation, and security certificate setup during manufacturing. This reduces on-site installation to simple plug-and-play operations that can be performed by non-specialized personnel, significantly reducing installation labor costs while maintaining system setup quality through the pre-configuration work.
