EV Charging Compatibility Matching for Connector and Power Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The incompatibility between electric vehicles (EVs) and charging infrastructure poses risks of damage to both the vehicle and the infrastructure, as well as safety risks to individuals, due to differences in charging connector types, power supply capabilities, and operating voltage requirements.
Innovation Solution
A system that utilizes non-transitory computer-readable storage devices with program instructions to acquire data on the geometry and power ratings of both vehicle charging features and infrastructure, enabling automatic matching and control of charging operations to ensure compatibility and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If EVs are connected to incompatible charging infrastructure, then charging operations can proceed without verification, but damage to the vehicle and infrastructure occurs along with safety risks
Solution Approach 1:
The system performs compatibility verification between EV and charging infrastructure before initiating charging operations. The controller acquires geometry data of charging features and power rating data for both the vehicle and infrastructure, then matches them to ensure compatibility is established in advance, preventing damage and safety incidents.
Solution Approach 2:
The controller continuously monitors charging parameters during operation and compares actual power output/input against rated power values. This feedback mechanism ensures the charging operation remains within safe and compatible parameters throughout the charging process.
2Reliability
If compatibility verification systems are implemented, then charging safety is improved, but system complexity increases
Solution Approach 1:
The EV and charging infrastructure automatically exchange and verify their own compatibility parameters through the controller. The system self-identifies geometry of charging features and power ratings, performing mutual verification without requiring complex external verification systems, thus enhancing safety while limiting complexity growth.
3Object-affected harmful factors
If automatic matching and control systems are deployed, then damage risk is reduced, but implementation cost increases
Solution Approach 1:
The controller performs multiple functions including acquiring geometry data, acquiring power rating data, matching compatibility, and controlling charging operations. By consolidating these functions into a single multi-functional controller, the system reduces the need for separate specialized components, thereby lowering implementation costs while maintaining comprehensive protection against damage.
Data Source
AI summary
A device includes program instructions executable by one or more processors that, when executed, cause the one or more processors to perform operations. The operations include acquiring data indicative of a geometry of a charging feature of a vehicle for charging a battery of the vehicle and a rated power input for the battery of the vehicle. The operations include acquiring data indicative of a geometry of a charging feature of charging infrastructure and a rated power output for the charging infrastructure. The operations include matching the vehicle to the charging infrastructure based at least on the geometry of the charging feature of the vehicle being compatible with the geometry of the charging feature of the charging infrastructure. The operations include automatically controlling an operation of at least one of the vehicle or the charging infrastructure when the vehicle is connected with the charging infrastructure.
