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

VSEngineering 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

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidcommunication error accumulation time
Core Design Contradiction:
ReliabilityVSLoss of time

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.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If communication parameters are reset frequently, then communication reliability improves, but system complexity and operation complexity increase

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidparameter management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #3Local quality

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.

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
Improveparameter management simplicityVSAvoidcommunication reliability
Core Design Contradiction:
Ease of operationVSReliability

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.

Inventive Principle:
Principle #10Preliminary action

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.
