Electrification is a key technological strategy to reduce air pollution, and it is also a promising option that helps countries achieve energy diversification and greenhouse gas (GHG) emission reduction goals. The benefits of EVs include zero tailpipe emissions, better efficiency than internal combustion engine vehicles, and large GHG emissions reduction potential. In 2010, there were only about 17,000 EVs on the world’s roads. Just five countries could count more than 1 000 EVs on their roads: China, Japan, Norway, United Kingdom, and United<br />States. However, by 2019, there were 7.2 million EVs on the world's roads. Nine countries had more than 100 000 EVs on the road [1]. The global stock remains concentrated in China, Europe, and United States, and it is worth noting that China has the largest number of EVs. With the continuous increase of EVs, the demand for charging infrastructure will increase accordingly. Governments have introduced a range of ambitious policies to support and structure a nascent EV industry, which include approaches to reduce adoption barriers and to promote the deployment of the needed charging infrastructure. By the end of 2019, 7.3 million EV chargers were installed worldwide, which increased by 40% from 5.2<br />million in 2018. Among them, the number of private slow chargers is the largest, followed by publicly accessible slow chargers, and the number of publicly accessible fast chargers is the least. The maximum number of private slow chargers indicates that EV users are more inclined to charge at home, while slow charging is conducive to protecting the battery life of EVs. The dramatic increase of EVs with the EVs’ charging infrastructure shows the people's increased acceptance of EVs to prove the transformation from the transportation driven by traditional internal combustion engines to the new transportation driven by modern power electronic system.<br /><br />
