The increased demand for EV charging is a problem that will need to be solved in the future. Even if there are more and more EV charging stations available every day, there are still some issues that must be resolved before access to charging stations is more widely available. Consideration should be given to three factors: location, time, and length.
As a result of their investigation, several academics from North Carolina State University created a dynamic computational tool to facilitate easier user access to EV charging stations. The ultimate objective is to increase the appeal of EVs while resolving some of the drivers’ charging-related issues.
We already know that flexible EV charging networks are necessary to enable the adoption of EVs, according to says Leila Hajibabai , an assistant professor in NC State’s Fitts Department of Industrial and Systems Engineering and the paper’s corresponding author. “That’s because there is a lot of variation in people’s preferences for where and when they want to charge their cars, how long they can stay at a charging station, how long it takes to charge their cars, and other factors.
What is the best strategy to manage the current infrastructure of charging stations in order to best fulfill the expectations of electric vehicle users? is the key question that this effort aims to answer.
In order to respond to that query, the researchers took a user-centered approach and concentrated on the key concerns EV drivers have, such as: How long will it take me to go to a charging station? How much does it cost to use the charging station? How long could the wait be before I can use a charging station? What kind of penalties are there if I stay at a charging station longer than allowed?
The researchers were able to construct a method that takes all of these considerations into account by building a complicated computational model within a game theory framework. The method could accomplish two things: It first assists drivers in finding the closest charging station to their location. Second, it helps the people running the charging stations decide how long a car can stay at a station so that the next driver in line who needs to charge their EV can get access.
According to Hajibabai, “These results are inherently dynamic — they change as new information about how users are using charging facilities” is received.
If there are no open spots at the moment, a driver intending to charge their vehicle may find that the closest charging facility changes as a result of this dynamic technique. Additionally, depending on how many people are using various charging stations on any given day, the overall length of time customers can spend at a charging station may alter.
The extent to which our technique will increase user access to charging facilities cannot be determined with certainty in the actual world, according to Hajibabai. “However, the strategy did enhance user access in simulations. The simulations also imply that users’ station visits are significantly influenced by the availability of charging station slots at various times.
The next stage would be to test the concept using already-established charging station networks and evaluate how well it performs in practical situations.
