Solution Overview
Problem
Electric vehicle drivers face challenges in understanding and efficiently charging their vehicles due to the lack of standardization across charging stations, with no clear indication of the required charging amount or time for a specific distance, leading to user inconvenience and limited adoption of EVs.
Innovation Solution
A system and method for remotely controlling EV charging using a user device, which captures metadata from the charging station, computes and displays relevant charging parameters, and transmits control commands to the charging device, enabling users to manage charging and payment in a user-friendly manner, facilitating flexible and standardized charging operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If charging stations operate with different procedures and parameters, then charging flexibility is provided, but user confusion and operational complexity increase
Solution Approach 1:
The system provides a universal charging interface that works across different charging stations and vehicle types. The portable device serves multiple functions including displaying charging parameters, calculating costs, and controlling the charging process, creating a standardized user experience despite variations in underlying charging infrastructure.
Solution Approach 2:
The portable device acts as an intermediary between the user and the charging station. It translates various charging station protocols and parameters into user-friendly information, and transmits user decisions back to the charging station, thereby mediating the interaction and eliminating direct user confusion.
2Loss of information
If drivers are provided with detailed charging information and control options, then charging understanding and control improve, but system complexity and computational requirements increase
Solution Approach 1:
The system divides the charging information into distinct, manageable segments displayed on the portable device. Instead of overwhelming the user with all possible parameters simultaneously, the system presents information in organized sections (charging rate, time, cost, distance) that can be individually understood and controlled.
Solution Approach 2:
The portable device performs automatic calculations of charging parameters, time required, and cost estimates based on input variables. This self-service computational capability provides detailed information without requiring complex user calculations or system overhead, as the device independently processes the information.
3Ease of operation
If standard charging procedures are implemented across all stations, then operational simplicity increases, but adaptability to different charging requirements decreases
Solution Approach 1:
The system dynamically adjusts charging parameters based on user selections and vehicle requirements. While the user interface maintains simplicity with standardized controls, the underlying system adapts charging rate, duration, and other parameters in real-time based on the specific needs indicated by the user, achieving both simplicity and flexibility.

AI summary
Disclosed is a system and method for controlling charging of an electric vehicle. The system captures metadata and at least one input value from a user device present in a charging location. The metadata is associated with a charging device, installed at the charging location, capable of charging one or more electric vehicles. The at least one input value corresponds to at least one charging parameter of a plurality of charging parameters associated with charging of an electric vehicle belonging to a user of the user device. The system computes values corresponding to one or more other parameters of the plurality of charging parameters based upon the at least one input value captured from the user device. The system displays the values computed on the user device for validation by the user. The system further transmits one or more control commands to the charging device to charge the electric vehicle.
