Smart Grid Charging Station Server Energy Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing charging station systems for electric vehicles are costly and require separate installations for different energy providers, leading to inefficient resource allocation and urban planning challenges, as they lack a centralized control mechanism to efficiently manage energy distribution from multiple providers.
Innovation Solution
A smart grid-based charging station system that utilizes a server to select and activate energy connections from multiple providers using subscriber identities transmitted via a cellular network, allowing for user-specific energy allocation and reducing the need for separate charging stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each energy provider operates their own charging stations, then energy providers can supply their customers with dedicated charging infrastructure, but the number of charging stations increases significantly leading to high costs and urban planning challenges
Solution Approach 1:
Multiple energy connections from different providers are merged into a single charging station through a server-based selection mechanism. The charging station can be connected to multiple energy connections, and the server selects the appropriate connection based on user subscription, eliminating the need for separate charging stations for each provider.
Solution Approach 2:
The charging station is designed with multi-functionality to serve multiple energy providers through a single infrastructure. The station can switch between different energy connections based on server selection, making one charging station universal for multiple providers rather than requiring dedicated stations for each.
2Adaptability or versatility
If multiple separate charging stations are installed for different energy providers, then each provider can control their own charging infrastructure, but the cost of installation and maintenance increases significantly
Solution Approach 1:
The system merges multiple energy provider connections into a single charging station infrastructure. Instead of deploying separate stations for each provider, the solution combines them through a server that manages connection selection, reducing overall deployment complexity and cost.
Solution Approach 2:
A server acts as an intermediary between multiple energy providers and the charging station. The server receives user identification, selects the appropriate energy connection, and activates the connection path, simplifying the interaction between multiple providers and a single charging station.
3Productivity
If a centralized server selects energy connections based on user identity, then resource allocation efficiency improves and separate installations are eliminated, but the system requires complex communication and control mechanisms
Solution Approach 1:
The server serves as an intermediary that automates the energy connection selection process based on user identification. This centralized control mechanism improves efficiency by automatically allocating the appropriate energy provider without requiring manual intervention or complex user decisions.
Solution Approach 2:
The system implements feedback loops where the server receives user identification information, selects the appropriate energy connection, and activates the connection path. The server continuously monitors and manages the connection status, providing feedback-based control for efficient energy provision.

AI summary
The invention relates to a charging station system 200 for providing electrical energy to a user's electric vehicle in a smart grid 201, which has a plurality of energy connections A, B, C, wherein each energy connection A, B, C is assigned to a different energy provider, and wherein the user is identifiable by a subscriber identity in a mobile network. The charging station system 200 includes a server 202 for selecting an energy connection A, B, C for providing electrical energy and a charging station 100 configured to provide electrical energy to the electric vehicle. The charging station 100 is electrically connectable to the plurality of energy connections A, B, C. The charging station 100 has an electrical connection 101 for providing the electrical energy to the electric vehicle and a communication interface 102.The communication interface 102 is configured to receive the user's subscriber identity and transmit it to the server 202 via the mobile network. Depending on the transmitted subscriber identity of the user, the server 202 is configured to select one of the power connections A, B, or C and to open a connection path between the charging station 100 and the selected power connection A, B, or C in order to establish an electrical connection between the selected power connection A, B, or C and the charging station 100 for the provision of electrical energy. The invention further relates to a charging station 100 and a method (Fig. 1).
