According to foreign media reports, with the rapid growth of electric vehicle sales, the growth rate of electric vehicles on the road has exceeded the number of public charging posts. New energy vehicle charging pile This is one of the conclusions drawn by Bloomberg New Energy Finance (BNEF), a research institution, after in-depth research on the status of public charging infrastructure.

Data shows that by the end of 2021, each public charging point in the world needs to provide charging services for 9.2 electric vehicles, while by the end of 2020, the number will be 7.4. Given that the sales volume of electric vehicles will increase significantly to 6.6 million in 2021, this situation is not surprising.

The situation varies from country to country. For example, the sales volume of electric vehicles in China set a new record last year, while the number of charging poles was also rising at the same time. Since 2018, the proportion between electric vehicles and charging piles in China has been relatively stable. The reason is that China is vigorously promoting the construction of charging infrastructure, and China has more than half of the world's public charging piles.

However, in the United States and other markets, the growth rate of charging piles lags behind that of electric vehicles, which makes it increasingly difficult for electric vehicles running on the road to find idle charging piles. This problem is particularly obvious in Europe, where the sales of electric vehicles have surged since 2019. For example, in Germany, 8 electric vehicles will be served by each charging point in 2019, Electric vehicle charging pile By 2021, the number will rise to 20.

Compared with markets such as the United States and Germany, China needs more public charging posts. Because most Chinese consumers live in multi-storey apartment buildings and it is difficult to charge at home, they rely more on public charging networks. In contrast, in non urban areas of the United States, 80% to 90% of electric vehicle owners can charge in their garage at home.

In terms of fast and ultra fast charging piles, China is still in the lead. Each ultra fast charging pile needs to serve 16 electric vehicles, while the United States has more than 100. The proportion of electric vehicles and charging piles varies in different countries, depending on the type of houses in the region, the strength of the power grid, charging speed, and government policies. The good news is that more and more 350 kilowatt charging piles have appeared in the market, which can increase the vehicle's endurance by 100 kilometers in just a few minutes.

In order to provide more support for electric vehicle owners, we need to make more private investment in charging infrastructure. In order to achieve this goal, it is necessary to improve the utilization rate of each charging pile to improve the economy of charging station operation.

At present, many charging stations are not fully utilized. BNEF data shows that most fast charging piles need 8 to 10 charging activities every day to begin to bring meaningful returns to investors. The specific figure depends to a large extent on the price, charging speed, site cost, charging structure, government support and other factors.

Charging station operators need to find a balance. Of course, they want to reduce the idle time of charging piles so that someone can charge at any time. However, this may worsen the charging experience of car owners, because having a car charged at any time means that they need to wait in line. What operators should pay attention to is that while improving utilization, they should also avoid making customers feel depressed.

In this regard, Tesla's super charging network has its own advantages. On average, each charging station has 10 fast charging piles, while other brands only have 2 to 4, which brings Tesla owners a better experience.

Each country will eventually form different charging combinations for homes, public and workplaces, as well as different power output distributions. Globally, the ratio of electric vehicles to charging piles may continue to rise in the next few years, which is not necessarily a bad thing.
