The electric vehicle (EV) market in the United States has been experiencing significant growth, with almost 1.2 million more electric vehicles sold in 2020 compared to previous years. This accounts for over 7 percent of total new car sales and is a new national record. However, there is a disparity between the growth in EV sales and the expansion of the charging network in the country.
Data shows that the number of electric cars on the road is far outpacing the growth of public charging points. In 2016, there were seven electric cars for each public charging point, but today, there are more than 20 electric cars per charger. This poses a challenge for EV owners who rely on public charging infrastructure, especially during long road trips or for those living in apartment buildings without access to private charging facilities.
Despite the rapid adoption of electric vehicles, experts argue that there is no one-size-fits-all solution to determine the ideal ratio of EVs to public chargers. The optimal ratio depends on the local landscape and varies from country to country. Globally, there is approximately one public charger for every 11 EVs, according to the International Energy Agency. However, in countries where there is a higher proportion of single-family homes with garages, the ratio may be lower.
The slow expansion of the charging network in the United States may have long-term benefits. Many automakers have pledged to adopt Tesla’s charging connector, which could lead to a standardized charging system. This would enable most electric cars to utilize the same charging infrastructure, making it more convenient for EV owners.
Contrary to concerns about the delay in charging infrastructure build-out, some researchers argue that the United States is on track to meet the charging needs of EVs over the next eight years. The increase in the number of EVs per public charger is a natural part of the adoption process and is likely to subside as more chargers come online and EV sales continue to grow. However, if the trend of Americans buying electric cars continues, the demand for public chargers will be crucial in supporting long road trips, assisting apartment-dwellers in transitioning to electric vehicles, and alleviating the strain on electricity grids during overnight charging.
Recognizing the importance of a robust charging network, U.S. Transportation Secretary Pete Buttigieg reaffirmed the country’s commitment to establishing a national network of 500,000 chargers by 2030. Although the charging infrastructure build-out is still in its early stages, the government aims to accelerate the development and ensure EV owners have convenient and accessible charging options across the country.
Expanding the charging network is not only essential for individual EV owners but also plays a crucial role in promoting widespread EV adoption and achieving environmental goals. It is imperative to address the challenges associated with deploying public chargers strategically and efficiently. This includes identifying optimal locations for charging stations, incentivizing private investments in charging infrastructure, and ensuring interoperability and compatibility among different charging systems to enhance user experience and convenience.
In conclusion, while the United States has witnessed a remarkable surge in electric vehicle sales, the growth of the charging network has not kept pace. This imbalance between EV sales and charging infrastructure development presents challenges for EV owners who rely on public charging facilities. However, experts suggest that the increase in the number of EVs per public charger will subside as more chargers come online and sales continue to grow. Nonetheless, to support long road trips, facilitate the transition to electric vehicles for apartment-dwellers, and alleviate strain on electricity grids, the expansion of the charging network is crucial. The government’s commitment to establishing a national network of 500,000 chargers by 2030 reflects the importance of this infrastructure in accelerating the adoption of electric vehicles and achieving sustainable transportation goals.
