What challenges will large-scale charging pile construction face?

In 2017, the sales volume of new energy passenger vehicles in China reached 576,000 units, ranking first in the world, equivalent to the total sales volume from the second to the tenth among the world's Top10 electric vehicle sales countries, and maintained a growth rate of up to 68%, according to the sales data of the passenger vehicle association. The China Association of Automobile Manufacturers expects sales of new energy vehicles to exceed 1 million in 2018.
Sales of new energy vehicles in China are increasing year by year at a high rate. As we all know, the development of electric vehicles cannot be separated from the progress of infrastructure, and one of the biggest pain points of electric vehicles is the issue of range. Problems such as insufficient driving range and inconvenient charging have always been a big concern of consumers. The Chinese government is also actively planning the construction of charging piles to solve these problems.
Statistics from China Ev Charging Infrastructure Promotion Alliance show that by the end of 2017, a total of 450,000 charging piles had been built, including 240,000 private ones and 210,000 public ones. In addition, according to the National Energy Administration's guidance on Energy Work in 2018, 600,000 charging piles are planned to be built in 2018, of which 100,000 are public and 500,000 are private.
It can be seen that the national and local governments are increasing investment in the construction of charging piles. Recently, the natural resources defense council (NRDC) and its Chinese energy research institute jointly issued the "electric car development impact on the distribution network and benefit analysis", the report shows that China has become the world's largest market, charging pile and large-scale charging infrastructure was put into operation, for the whole power grid, power distribution network, and the development of the power supply has brought new challenges.
Overall grid: peak load increase
For the use of special facilities, the difference between peak and valley is more obvious. Especially for the charging behavior of electric vehicles, the peak load of charging in the evening will be great
