EV Charging Station Fault Detection and Status Update
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of standardized information about the operating status and reliability of charging stations for electric vehicles leads to unreliable charging operations, causing vehicles to be unable to charge fully or at all, which can result in incomplete trips or prolonged waiting times.
Innovation Solution
A system that includes a detection unit in electric vehicles to identify faulty charging station states and transmit this information to a backend, which uses algorithms to uniquely identify the charging station and update POI databases, ensuring users can avoid non-operational stations and plan charging stops optimally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If charging stations are used without standardized operating status information, then charging operations can be attempted at any station, but the reliability of charging operations deteriorates due to faulty or non-operational stations
Solution Approach 1:
The system implements feedback by collecting actual charging operation data from vehicles at charging stations and transmitting it to a backend server. The backend processes this data to determine operating status information, which is then fed back into the system to update POI databases and provide real-time status information to users, creating a closed-loop information flow that continuously improves reliability.
Solution Approach 2:
The system performs preliminary action by proactively determining and storing operating status information in POI databases before users attempt charging operations. By pre-collecting data from successful charging operations and maintaining updated status information in advance, the system enables users to make informed decisions about which charging stations to use, avoiding faulty stations before arrival.
2Loss of time
If users wait at charging stations during charging operations, then charging can be performed, but time is lost due to lack of alternative activities or infrastructure
Solution Approach 1:
The system determines and stores infrastructure information in POI databases in advance, including details about amenities and services available at charging station locations. This preliminary preparation allows users to plan their charging stops more efficiently by selecting stations with desirable infrastructure, reducing perceived waiting time and making charging stops more productive.
3Loss of information
If POI databases contain insufficient information about charging stations, then database simplicity is maintained, but users cannot make informed decisions about charging station selection
Solution Approach 1:
The backend server performs multiple functions: collecting charging operation data, determining operating status information, updating POI databases, and providing information to users. This multi-functional approach consolidates complexity into a single centralized system rather than distributing it across multiple components, allowing the POI databases to remain relatively simple while still providing comprehensive information.

AI summary
A system for robustly detecting faulty operating states of charging stations includes a backend and an at least partially electrically powered vehicle. The at least partially electrically powered vehicle includes a detection unit configured to detect a faulty operating state of a charging station with respect to a charging operation at the charging station, and a communication unit configured to transmit a message data set comprising the detected faulty operating state of the charging station to the backend. The backend is configured to use the message data set to determine a unique identification of the charging station having the detected faulty operating state.
