Benefits of AI in Electric Vehicle Charging
By: Ankur Gupta & Swagata Ashwani
Artificial intelligence (AI) has the potential to revolutionize the accessibility and availability of electric vehicle (EV) charging. With the transportation industry shifting towards electric vehicles, the demand for EV charging is rapidly increasing. In 2021, over 6.5 million EVs were sold worldwide, accounting for 9% of passenger car sales. This number is projected to exceed 25% by 2030. An analysis suggests that the number of charging stations required to meet the growing demand would need to grow 10 times by 2040 [1].

AI algorithms can help create a smarter and more responsive charging infrastructure. As we welcome the benefits of AI, it’s important to ensure that rapid deployment aligns with values such as fairness, transparency, and accountability. We need to control for bias based on socio-economic factors to ensure fair and equitable access to new charging stations.
Scientific studies [2,3] discuss how AI and machine learning can help planners decide where to locate EV chargers and what type of chargers to install. Designing an EV charging grid is complex, with various factors at play including charger location, pricing, charging standards, energy grid balancing, and demand prediction.
1. Optimal Charging Station Placement
AI excels in processing vast datasets and extracting meaningful insights. By analyzing factors such as traffic patterns, population density, and geographic data, AI algorithms can strategically place charging stations to maximize accessibility and user convenience.

2. Demand Prediction
An effective demand prediction strategy is crucial for optimizing the placement and operation of charging stations. By forecasting when and where charging needs will be highest, AI-driven systems can optimize the geographic distribution of charging infrastructure.
3. Dynamic Charging Pricing Models
AI can analyze real-time data, including energy demand, grid load, and user behavior, to implement dynamic pricing models. This not only optimizes the utilization of the charging infrastructure but also encourages users to charge during off-peak hours, promoting a more balanced and sustainable energy distribution.

The adoption of AI-driven solutions in EV charging is rapidly advancing, offering potential benefits in efficiency, user experience, and grid management. However, ensuring that AI systems in EV charging are fair and unbiased is critical to promoting equitable access to charging infrastructure.
Diverse and Representative Data
To mitigate biases, it’s crucial to ensure that training data are diverse and representative of the entire user base. This involves collecting data from a broad range of geographic locations, demographic groups, and charging scenarios.
