EV Charging Point Extender for Multi-System Message Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle charging station systems are limited in their ability to communicate with multiple charging point management systems, leading to inefficiencies in message transmission and functionality, as they typically rely on fixed addresses and protocols that do not allow for seamless integration with various management systems.
Innovation Solution
An extender device is introduced that connects a charging station to multiple charging point management systems, using a processor, memory, and network interfaces to relay messages and responses according to a predetermined scheme, incorporating features like whitelists, blacklists, and routing tables to filter and route messages effectively, allowing the charging station to appear as a single entity to both systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a charging station uses a fixed address or domain name to communicate with a charging point management system, then the communication is stable and simple, but the charging station cannot communicate with multiple charging point management systems simultaneously
Solution Approach 1:
The patent introduces an extender as an intermediary device between the charging station and multiple charging point management systems. The extender receives messages from the charging station using a fixed address, and then relays these messages to multiple target charging point management systems according to routing rules stored in its memory. This mediator approach allows the charging station to communicate with multiple systems without requiring the station itself to have complex multi-address communication capabilities.
Solution Approach 2:
The extender is designed as a universal intermediary that can handle communication with multiple different charging point management systems simultaneously. By storing multiple target addresses and routing rules in its memory, the single extender device provides multi-functionality, enabling one charging station to access multiple management systems through a unified interface.
2Productivity
If the charging station relays messages to multiple charging point management systems without filtering, then all systems receive the messages, but unnecessary message transmission increases communication overhead and processing time
Solution Approach 1:
The extender implements local quality by applying different routing rules to different message types. Instead of uniformly relaying all messages to all charging point management systems, the extender's memory stores specific routing rules that match message types with appropriate target systems. This ensures that each message is delivered only to the most relevant system, reducing unnecessary transmissions and improving overall communication efficiency.
Solution Approach 2:
The extender performs preliminary action by pre-storing routing rules and target addresses in its memory before message transmission occurs. When a message arrives from the charging station, the extender can immediately consult its pre-configured routing rules to determine the appropriate target system, eliminating the need for real-time decision-making and reducing message transmission delays.
3Adaptability or versatility
If the charging station integrates multiple charging point management system functionalities, then the functionality is expanded, but the system configuration and integration complexity increases
Solution Approach 1:
The extender serves as an intermediary that consolidates the complexity of integrating multiple charging point management systems. Instead of requiring the charging station to directly integrate with multiple systems, the extender handles all integration logic, message routing, and protocol translation in one centralized location. This allows the charging station to access expanded functionality from multiple systems without bearing the integration complexity.
Solution Approach 2:
The patent segments the system into distinct functional components: the charging station, the extender, and multiple charging point management systems. The extender is segmented as a separate intermediary component that handles all communication and routing logic. This segmentation allows each component to remain relatively simple while the overall system achieves high versatility through the coordinated interaction of segmented parts.

AI summary
An extender for connecting a charging station to a plurality of charging point management systems is disclosed. The extender is connected between a charging station and a charging point management system. The extender is then configured to transmit messages received from the charging station to one or more charging point management systems. This provides a possibility to use services that the original charging point management is not able to perform for various reasons.
