EV Charging Device Registration via Memory Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of electric vehicles requires a reliable method for registering electric charging devices with administration computers to ensure safe and efficient operation, preventing unauthorized charging and ensuring that only compatible electric vehicles can use the charging facilities.
Innovation Solution
A method where registration data, including a unique identifier and additional device-specific information, are transmitted from the charging device to a central administration computer, with the charging device assuming a ready state only after receiving a registration confirmation message, allowing for secure and reliable operation, even in remote areas without internet connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the charging device assumes charging readiness immediately after installation, then charging operations can start quickly, but unauthorized or unregistered charging may occur and central control is lost
Solution Approach 1:
The charging device performs preliminary registration actions with the central administration computer before assuming charging readiness. The device transmits its identification data to the administration computer and waits for confirmation, ensuring centralized authorization is established before the charging function becomes active.
Solution Approach 2:
The system implements a feedback mechanism where the administration computer sends a registration confirmation message back to the charging device. The charging device only transitions to charging readiness state after receiving this confirmation, ensuring centralized control and authorization verification before operation.
2Manufacturing precision
If manual data input is required for charging device registration, then data accuracy can be verified, but installation time increases and human errors occur
Solution Approach 1:
The charging device automatically reads its own identification data from an integrated memory module and transmits it to the administration computer without requiring manual data entry. This self-service approach eliminates human input errors and significantly reduces installation time while maintaining data accuracy.
Solution Approach 2:
The manual mechanical process of data entry is replaced with an automated electronic system. The memory module stores identification data that is automatically read by the charging device's control unit and transmitted electronically to the administration computer, replacing the need for manual typing or form filling.
3Ease of manufacture
If Internet connection is required for registration, then easy and inexpensive data transfer is achieved, but charging devices in remote areas cannot register
Solution Approach 1:
The charging device is designed with multi-functional communication capabilities, supporting both Internet-based data transfer and mobile communication network transmission. This universality allows the device to adapt to different deployment environments, whether connected to the Internet or only available through mobile networks in remote areas.
Solution Approach 2:
The communication method used for registration is dynamically selected based on availability. The charging device can switch between Internet connection and mobile communication network depending on which is available at the deployment location, making the system adaptable to various environmental conditions.

AI summary
The invention relates to a method for logging an electrical charging device (1) for an electric vehicle (9) onto an administration computer (40). In said method, log-on data containing at least one unique identifier of the charging device are read out from a memory module (30) of the charging device (1). Said log-on data are transferred from the charging device (1) to a central administration computer (40). A log-on confirmation message that was sent by the administration computer (40) after the administration computer had received the log-on data of the charging device is received by the charging device (1). Upon receiving the log-on confirmation message, the charging device (1) assumes a ready-for-charging state.
