Solution Overview
Problem
Existing electric vehicle charging systems rely on external communication infrastructures like WiFi or mobile networks for transmitting measurement data, which are costly, require configuration by owners or service personnel, and may become outdated, leading to operational issues.
Innovation Solution
A system using point-to-point radio communication transceivers between an electrical cabinet and a charging box to autonomously transmit and receive data on instantaneous electrical current consumption, eliminating the need for external communication infrastructures and reducing recurring subscription costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If WiFi infrastructure or mobile network subscription is used for transmitting measurement data, then communication between electrical cabinet and charging box is enabled, but installation complexity increases and recurring subscription costs are incurred
Solution Approach 1:
The patent introduces a dedicated short-range wireless communication transceiver as an intermediary communication device between the electrical cabinet and charging box. This transceiver operates independently of external WiFi or mobile networks, providing a direct communication channel that eliminates the need for external infrastructure while maintaining reliable data transmission for load balancing measurements.
Solution Approach 2:
The system implements self-service communication by equipping both the electrical cabinet and charging box with integrated transceivers that automatically establish direct wireless communication. This eliminates the need for external network configuration, subscription management, or third-party infrastructure, allowing the system to communicate autonomously without recurring costs or complex installation procedures.
2Loss of information
If external communication infrastructure is used, then data transmission is possible, but recurring subscription costs are incurred
Solution Approach 1:
The system implements self-service communication by equipping both the electrical cabinet and charging box with integrated transceivers that automatically establish direct wireless communication. This eliminates the need for external network configuration, subscription management, or third-party infrastructure, allowing the system to communicate autonomously without recurring costs or complex installation procedures.
3Reliability
If WiFi infrastructure is used, then measurement data can be transmitted, but the system becomes dependent on external infrastructure that may become outdated
Solution Approach 1:
The system implements self-service communication by equipping both the electrical cabinet and charging box with integrated transceivers that automatically establish direct wireless communication. This eliminates the need for external network configuration, subscription management, or third-party infrastructure, allowing the system to communicate autonomously without recurring costs or complex installation procedures.
