Setting a communication parameter of a communication module of a charging station
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems in charging stations are insufficiently calibrated for reliable communication due to environmental and installation-specific factors, necessitating complex and costly methods like type or unit calibration, which are not easily adaptable during operation.
Innovation Solution
A portable calibration device is used to set communication parameters via the charging station's interface, utilizing authentication data to ensure only authorized devices can adjust parameters, eliminating the need for a permanent communication link and allowing on-site configuration without modifying hardware or software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication parameters are not reset after charging completion, then communication continuity is maintained, but communication errors accumulate and system reliability deteriorates
Solution Approach 1:
The system performs preliminary actions by resetting communication parameters at the end of each charging session before new communication occurs. This proactive reset prevents error accumulation and ensures clean communication state for the next charging cycle, improving reliability without affecting charging speed.
2Reliability
If communication parameters are reset frequently, then communication reliability improves, but system complexity and operation complexity increase
Solution Approach 1:
The reset operation is applied locally and selectively only to the communication parameter set associated with completed charging sessions. Rather than implementing a global reset mechanism that would affect all communications, the system targets specific parameter groups, reducing management complexity while maintaining reliability.
Solution Approach 2:
The system automatically resets parameters as a preliminary action at the end of each charging session, eliminating the need for manual intervention or complex continuous monitoring mechanisms. This automated preliminary reset simplifies operation while ensuring reliability.
3Ease of operation
If communication parameters persist across charging sessions, then system operation simplicity is maintained, but communication errors from previous sessions affect new sessions
Solution Approach 1:
The system automatically performs parameter reset as a preliminary action at the end of each charging session, ensuring clean communication state for the next session without requiring user intervention. This maintains ease of operation while eliminating error carryover that would compromise reliability.

AI summary
The invention relates to a method for setting at least one communication parameter of a communication module (28) of a charging station (10), used for communication, in particular wired communication, via an interface (18) of the charging station (10). The invention addresses the problem of enabling the at least one communication parameter to be set in the simplest manner possible, with significant reliability and great security. It is proposed according to the invention that: - a calibration device (56) is coupled to the interface (18), - authentication data is transmitted from the calibration device (56) to the communication module (28), - a value for the at least one communication parameter is transmitted from the calibration device (56) to the communication module (28), and - the at least one communication parameter is set by the communication module (28) depending on an evaluation of the authentication data by the communication module (28) according to the value transmitted.
