Public charging infrastructure for electric vehicles (EVs) is crucial for widespread adoption, particularly in dense urban areas where home charging may be limited. By the end of 2022, there were 2.7 million public charging points globally, with significant growth in slow chargers, mainly in China and Europe, and fast chargers, driven largely by China. Notably, China accounted for over half of slow chargers and about 90% of fast chargers.
Efforts to expand public charging infrastructure are evident, with initiatives like the European Union’s Alternative Fuels Infrastructure Regulation and the US National Electric Vehicle Infrastructure Program. However, the ratio of EVs to public chargers varies across regions, with Norway having over 30 EVs per charger, emphasizing the need for further infrastructure development.
Moreover, the total public charging power capacity per EV is crucial, with the global average around 2.4 kW per EV. Ensuring adequate charging power capacity is essential for accommodating the growing EV market. In summary, the expansion of public charging infrastructure is vital for supporting EV adoption worldwide, requiring a balance between the number of chargers, their distribution, and their power capacity.
