EV Charging Socket Data Setup for Branch Current Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing charging systems for electric vehicles are complex and require skilled personnel for setup, posing safety risks and high costs due to the need for experienced electricians, and often result in mistakes that can lead to accidents or incorrect installations.
Innovation Solution
A charging assembly comprising an electrical socket with a data storage medium and a charging station that can read this data to adapt current draw and communicate with other stations, allowing for automatic distribution of electrical current and eliminating the need for skilled operators by pre-configuring the system with RFID tags and communication units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a charging station is manually configured by a skilled electrician, then the setup accuracy and safety are improved, but the cost and time consumption increase
Solution Approach 1:
The electrical socket is pre-configured with a data storage medium containing identification data and branch information before the charging station is installed. This preliminary configuration eliminates the need for manual setup by skilled electricians, allowing anyone to install the charging station by simply connecting it to the pre-configured socket.
Solution Approach 2:
The charging station automatically reads the identification data from the data storage medium in the electrical socket and self-configures to operate on the correct branch. This self-service mechanism replaces manual configuration by electricians, reducing both time and cost while maintaining reliability through automated data-driven setup.
2Adaptability or versatility
If multiple charging stations are connected to one branch, then the system versatility is improved, but the current distribution complexity increases
Solution Approach 1:
The charging stations communicate with each other through a communication network, exchanging information about their operational status and current consumption. This feedback mechanism allows the system to dynamically adjust current distribution among multiple stations connected to the same branch, managing complexity through automated coordination rather than manual control.
Solution Approach 2:
The electrical socket with data storage medium serves multiple functions: it provides electrical connection, stores identification data, and enables automatic configuration. This multi-functional design allows the same infrastructure to support multiple charging stations with different requirements, enhancing versatility without proportionally increasing complexity.
3Productivity
If pre-configured charging stations are transported and installed, then the setup time is reduced, but the risk of installation errors increases
Solution Approach 1:
The data storage medium in the electrical socket acts as an intermediary that provides authoritative configuration data to the charging station. Instead of relying on human memory or external documentation, the charging station reads its operational parameters directly from the socket's data storage medium, ensuring accurate installation without requiring skilled personnel to remember or reference complex configuration details.

AI summary
A charging assembly is for charging an electric vehicle. The charging assembly has an electrical socket configured for connecting a charging station to a specific branch an electric vehicle supply installation. The installation has a fuse cabinet and a branch connected to the fuse cabinet. The socket has a data storage medium readable by the charging station. The data storage medium has a data field representing a maximum electrical current that can be drawn from the fuse cabinet by the specific branch, and optionally a data field representing a maximum electrical current that can be drawn by the charging station. The charging station can be coupled to the electrical socket, and is configured for reading the data storage medium including the data fields and for accordingly adapting the way current is drawn from the branch and provided to the electric vehicle.
