EVSE Onboarding Gateway With Staging Service Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The onboarding of electric vehicle charging stations to a central management system is resource-intensive and prone to service delays and interruptions due to the need for manual verification and configuration, especially when dealing with unknown or unregistered stations.
Innovation Solution
Implementing an onboard gateway that determines the connectivity of EVSEs to a central management system based on their identifiers and IP addresses, routing unknown stations to a staging service for secure onboarding, thereby eliminating manual configuration and reducing service delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual verification and configuration is performed for each EVSE to connect to the central management system, then security and authorization are ensured, but the onboarding process becomes resource-intensive and time-consuming
Solution Approach 1:
The patent introduces a staging service as an intermediary component between the EVSE and the central management system. This staging service handles the initial connection requests from unknown EVSEs, performs verification, and manages the onboarding process automatically. The staging service acts as a mediator that reduces the manual intervention required while maintaining security protocols, thus resolving the contradiction between security reliability and onboarding productivity.
2Reliability
If manual configuration is performed for each unknown EVSE, then proper authorization is achieved, but service delays and interruptions occur
Solution Approach 1:
The staging service performs preliminary actions by pre- verifying and authorizing EVSEs before they fully integrate into the central management system. The system proactively manages the onboarding process, including automatic verification of EVSE identifiers and configuration of connection parameters, before the EVSE becomes operational. This preliminary automated authorization eliminates service delays that would otherwise occur during manual configuration.
3Adaptability or versatility
If a centralized approach is used to manage EV charging stations, then system-wide optimization is enabled, but the onboarding of new stations requires significant resources
Solution Approach 1:
The patent segments the central management system into distinct functional components: the main central management system for system-wide optimization and the staging service for handling onboarding operations. This segmentation allows the complex onboarding tasks to be isolated in the staging service, preventing them from overwhelming the central management system. The staging service handles the complexity of individual EVSE onboarding, while the central system maintains its optimization capabilities, thus resolving the contradiction between adaptability and device complexity.

AI summary
Certain aspects of the present disclosure provide techniques for electrical vehicle charging management. In examples, techniques may include receiving one or more packets including a first request from a first electric vehicle supply equipment (EVSE) to connect to a central management system, wherein: the first request from the first EVSE includes a first identifier associated with the first EVSE, and the one or more packets further include an Internet Protocol (IP) address associated with a Uniform Resource Locator (URL); determining whether the first EVSE is allowed to connect to the central management system based on the first identifier; and sending first data related to the first request from the first EVSE to a staging service based on a determination that the first EVSE is not allowed to connect to the central management system based on the first identifier.
