Charging Post Activation via Automatic Contract Certificate Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging systems require manual selection of certificates for charging processes, which is inconvenient and can lead to suboptimal billing due to multiple certificates being present, lacking flexibility and efficiency.
Innovation Solution
A computer-implemented method and system that automatically selects a suitable digital certificate from multiple mobility provider contracts based on preconfigured characteristics, such as charging process details, vehicle user, and contract data, to authenticate and activate the charging station for optimal billing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple contract certificates are stored in the vehicle for different mobility providers, then the user has flexibility in choosing charging contracts, but the user must manually select the appropriate certificate for each charging session, which reduces convenience and increases complexity
Solution Approach 1:
The system enables automatic certificate selection and authentication without user intervention. The vehicle's control system automatically selects the appropriate contract certificate based on the charging station's requirements and performs authentication, eliminating the need for manual user input and making the system serve itself
Solution Approach 2:
Multiple contract certificates are pre-stored in the vehicle's data storage device before charging sessions begin. The system prepares by having all necessary certificates ready and automatically selects the appropriate one during authentication, performing the selection action in advance of the actual charging process
2Ease of operation
If the user manually selects a certificate for charging authentication, then the user can choose which contract to use, but the user may inadvertently select a certificate with unfavorable billing conditions, leading to suboptimal costs
Solution Approach 1:
The system receives information from the charging station about which contract certificates are accepted and their associated billing conditions. Based on this feedback, the system automatically selects the certificate that provides the most favorable billing conditions for the user, ensuring optimal cost outcomes
3Productivity
If the vehicle authenticates itself automatically using a default contract certificate, then the charging process is simplified and faster, but the vehicle may use a certificate with unfavorable conditions even when a better option is available
Solution Approach 1:
The system dynamically selects the appropriate contract certificate based on real-time conditions at the charging station and the user's preferences. Rather than using a static default certificate, the system adapts its selection to the specific charging context, balancing speed and optimality
4Reliability
If the user is required to independently review contract terms and conditions for each charging station, then the user can make informed decisions, but this process increases time consumption and reduces convenience
Solution Approach 1:
The system automatically compares contract terms and conditions across multiple certificates and selects the most favorable one without requiring the user to manually review each option. The system serves itself by performing the information gathering and comparison tasks that would otherwise require user time and effort

AI summary
Computer-implemented method and system for activating a charging station (LS) for carrying out a charging process by a vehicle (F), comprising the steps of: providing (S1) certificates (Z) from mobility provider contracts that exist between one or more vehicle users (N) of the vehicle (F) and mobility providers (MSP); selecting (S2) a suitable certificate from the provided certificates (Z) depending on characteristics of the charging process to be carried out and/or the current vehicle user (N) and/or the vehicle (F) and/or depending on data from the mobility provider contracts; and authenticating (S3) the vehicle (F) with the charging station (LS) using the selected certificate (Z) to activate the charging station (LS) for carrying out the charging process.
