Electric mobility represents a paradigm shift toward a more energy-efficient, low-carbon, and environmentally friendly mode of transport. Choosing the optimal locations for Electric Vehicle (EV) charging stations is critical for EV adoption. Since EVs emit fewer greenhouse gases than internal combustion engines, their adoption is considered to be more environmentally friendly. Numerous factors affect the location-allocation problem for EV public charging stations, including understanding demand, assessing needs, identifying possible locations, and selecting an optimization model for facility location. This study conducts a literature review on the optimization of electric vehicle charging stations. Conclusions and recommendations for future research were extracted and documented
