Charging Pole Pre-Authentication Reduces EV Charging Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electric vehicle charging processes are slow due to low charging power and lengthy user interaction, as well as difficulties in finding available charging stations, especially in areas with low density, leading to prolonged charging times.
Innovation Solution
A method and charging pole system that registers and evaluates a first initial process independently of user input, allowing the charging process to start before the user's command, including sensor detection and pre-authentication, to optimize energy transfer and reduce charging time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the charging process starts only after user authentication and cable connection, then the charging process is secure and controlled, but the charging time is prolonged due to lengthy user interaction
Solution Approach 1:
The system performs preliminary actions by automatically detecting vehicle arrival through sensors and pre-authenticating users via mobile apps before the actual charging process begins. This allows the charging infrastructure to be ready and waiting, eliminating the time users would otherwise spend on authentication and setup at the charging station.
Solution Approach 2:
The charging system serves itself by automatically detecting when a vehicle arrives, initiating authentication processes, and preparing charging parameters without requiring manual user input. The system uses sensor data and pre-stored user information to autonomously complete tasks that traditionally required active user participation.
2Productivity
If charging power is increased to reduce charging time, then charging speed improves, but the complexity of the charging device increases
Solution Approach 1:
The charging system dynamically adjusts charging parameters such as power levels and current based on real-time conditions including vehicle battery state, grid availability, and user preferences. This dynamic adaptation allows the system to optimize charging speed without requiring permanently oversized infrastructure, balancing performance with device complexity.

AI summary
The invention relates to a method for generating and delivering charging current for an electric vehicle in a charging pole with the method steps of registering a first initial process, evaluating the first initial process, starting the charging process depending on the evaluation result, wherein the first initial process is different from a start command of a user for starting a charging process, and a charging pole for carrying out the method.
