With the rapid popularity of electric vehicles, the demand for high-power charging piles continues to grow. This trend not only brings new development opportunities, but also brings many challenges and pressures to the State Grid. This article will discuss the demand and growth of high-power charging piles, the challenges and problems faced by the State Grid, and solutions and suggestions, and put forward some specific suggestions and thoughts

Recently, the International New Energy Network issued an article ” More and more high-power charging piles, can the national grid bear it?“

1.Demand and growth of high-power charging piles

The rapid development of the electric vehicle market is driving the need for charging infrastructure.

In order to meet the charging needs of electric vehicle users during driving, the construction of high-power charging piles has become a focus.

These charging piles have the characteristics of fast charging speed and high charging power, which can greatly shorten the charging time and improve the charging efficiency, thereby bringing a better user experience.

According to statistics, the cumulative number of new energy vehicle charging piles nationwide in 2022 will be 5.21 million, including 1.398 million public charging piles and 3.812 million private charging piles.

By 2025, the cumulative number of new energy vehicle charging piles nationwide will reach 9.61 million.

This means that in the next few years, the number of charging piles will continue to grow, and the demand for high-power charging piles will also continue to increase.

2.Challenges and problems faced by State grid

The popularity of high-power charging piles has brought many challenges and problems to the State Grid.

First of all, as the number of charging piles increases, the load on the power grid is also increasing.

Especially during peak periods of electricity consumption, a large number of electric vehicles charging at the same time will put great pressure on the power grid, which may lead to grid collapse or power outages and other accidents.

Secondly, the power grid construction in some areas is relatively lagging behind and the power supply capacity is insufficient to meet the power demand of high-power charging piles.

In addition, rapid charging of high-power charging piles will cause current fluctuations and affect the stability of the power grid.

This requires the State Grid to upgrade and improve its technology and equipment to ensure the stable operation of the power grid.

In addition to technical and equipment challenges, the construction and management of high-power charging piles has also brought new problems to the State Grid.

On the one hand, the construction of high-power charging piles requires a large amount of capital investment, including site rental, equipment procurement, installation and construction and other links.

On the other hand, as the number of charging piles increases, subsequent maintenance and management have also become an important issue.

How to ensure the normal operation, timely maintenance and customer service management of charging piles has become another challenge faced by the State Grid.

3.Solutions and suggestions

In order to cope with the challenges and pressure brought by the popularization of high-power charging piles, the State Grid needs to take a series of measures.

First, strengthening power grid planning and construction is key.

The State Grid should work closely with the government, enterprises and research institutions to plan and build the power grid in advance according to the development trend of the electric vehicle market to improve power supply capacity and stability.

At the same time, attention should be paid to the transformation and upgrading of the existing power grid to meet the power demand of high-power charging piles.

Secondly, optimizing power grid operation and management is also very important.

By applying advanced power electronics technology and intelligent control strategies, the operation and management of the power grid can be optimized and the impact of current fluctuations on grid stability can be reduced.

In addition, strengthening power dispatching and management, rationally allocating power resources, and ensuring efficient operation of the power grid are also key.

At the same time, it is also necessary to promote the coordinated development of new energy and power grids.

New energy power generation is characterized by intermittent and unstable characteristics, while the charging load of electric vehicles is also random and fluctuating.

Therefore, it is necessary to strengthen the coordination and coordination between new energy and power grids and improve the power supply capacity and stability of the power grid.

In addition, it is also very important to guide users to use charging piles appropriately.

Through policy guidance and other means, users are encouraged to choose reasonable charging time and locations to avoid concentrated charging during peak power consumption periods, which can effectively reduce the pressure on the power grid.

At the same time, it is also necessary to promote the application of smart charging technology. Smart charging technology can achieve flexible control and optimal utilization of charging piles to improve the utilization efficiency of the power grid.

Finally, it is also very important to strengthen international cooperation and exchanges.

Facing common global issues, it is the common responsibility of the international community to jointly respond to the challenges and pressures brought about by the popularization of electric vehicles.

International cooperation and exchanges can help countries share technological achievements and experiences and lessons, jointly promote the development of the electric vehicle market and progress in power grid construction, and achieve win-win development.
