The word cloud has features of varying sizes, with word sizes decreasing as they radiate outward from the center. At the center, the largest words are “charging (batteries).” Between these words, at the bottom, the letters “e v” appear. Above “charging” and “batteries,” the phrase “electric vehicle charging and secondary batteries” is displayed. Surrounding the central cluster are smaller terms such as “electric power transmission networks,” “electric vehicles (e v s),” “technology adoption,” “charging facilities,” “electric automobiles,” “vehicle-to-grid,” “costs,” “optimization,” “greenhouse gases,” “energy utilization,” “vehicle sales,” “fleet operations,” “transportation infrastructure,” “decision making,” “integer programming,” “infrastructures,” “location,” “commerce,” “stochastic systems,” “charging stations,” “charging,” “electric power distribution,” “sustainable development,” “transportation planning,” “battery management systems,” and “battery-electric vehicles,” among others.Word cloud of EVs and charging infrastructure.
