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

VSEngineering 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

Engineering Contradiction:
Improveproper setup and configurationVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

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.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If pre-configuration is performed during manufacturing, then on-site installation is simplified, but manufacturing process complexity increases

Engineering Contradiction:
Improveon-site installation simplicityVSAvoidmanufacturing process complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

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.

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
Improvesetup timeVSAvoidconfiguration accuracy
Core Design Contradiction:
Loss of timeVSReliability

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.

Inventive Principle:
Principle #23Feedback

4Reliability

If specialized technicians are required for configuration, then proper system setup is ensured, but installation cost increases

Engineering Contradiction:
Improvesystem setup qualityVSAvoidinstallation cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

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.

Inventive Principle:
Principle #10Preliminary action
