China's new energy vehicle industry has real problems such as insufficient total number of charging piles, low utilization rate, unreasonable layout and non-uniform interface, and is waiting to establish a unified charging infrastructure standard system, improve technical performance and information level, strengthen overall construction and optimize regional layout.

Although the battery technology and vehicle performance of new energy vehicles have made great progress under the policy promotion, there are still real problems such as insufficient total amount of charging infrastructure, low utilization rate, unreasonable layout and non-uniform interface. It is far-reaching to consolidate the charging infrastructure for the renewal of new energy vehicles.

Establish a unified charging station standard system

It is necessary for the relevant departments to develop unified national standards, industry standards and enterprise standards as soon as possible to form an effective and complementary standard system for charging pile manufacturers.

First, fully understand the objective requirements for the construction of charging infrastructure, and develop unified national standards for the relevant industries and enterprises involved in new energy vehicles. Under the guidance of national standards, local relevant industries and enterprises should develop specific implementation standards in terms of charging station site planning, safety precautions, operation services, and regular maintenance.

Second, a unified national standard should be established for the core products of charging infrastructure. Relevant government departments should develop a market access system for charging products, especially to establish a unified product certification standard for charging interfaces nationwide.

Third, accurate price positioning for user charging services, the charging product cost, service cost, billing method, charging method and other related standards should likewise be guided by national standards, and specific industry standards and enterprise standards should be developed in various places.

In addition, the built and under-construction charging infrastructure should be updated in a timely manner according to the new standards, and charging infrastructure enterprises should be required to produce according to the new standards, as well as the relevant service industries should be required to charge according to the new standards.

Improve the technical performance and information level

At present, the technical performance and information level of charging infrastructure is low, which is highlighted by the phenomenon of "fast-charging pile not on, slow-charging zombie pile". Therefore, the charging infrastructure of new energy vehicles should not only ensure the demand of vehicle owners for charging in terms of "quantity", but also improve the charging speed in terms of "quality", so as to alleviate the dilemma of "difficult charging and slow charging" of new energy vehicles. The dilemma of "difficult and slow charging" of new energy vehicles.

In this regard, the government should play the role of policy guidance to achieve intelligent charging methods, high quality charging facilities, charging information connectivity. It is recommended to increase technical research and development to improve the technical performance of new energy vehicle charging infrastructure. On the one hand, we should fully mobilize the enthusiasm of colleges and universities and scientific research institutions, and set up special research projects by bidding or commissioning, etc. to promote the technical innovation of charging infrastructure, especially power supply. Strive for breakthroughs in solar charging technology, fast charging technology, solid-state battery technology, flexible battery technology, etc.

On the other hand, fully mobilize the driving role of market forces such as charging infrastructure manufacturers, operators and service providers to truly apply new technologies to product production and operation and services, and provide users with charging infrastructure with world-leading level and high technological content.

At the same time, the level of information technology should be improved with the help of Internet technology to build an interconnection network of new energy vehicle infrastructure information. Local governments, production enterprises and service industries and other related bodies should strengthen joint and collaborative cooperation, build information service platforms, establish data sharing, dynamic monitoring, site layout and other aspects of interoperability for charging infrastructure, and effectively solve the problems of charging users in finding piles, connectivity and settlement.

Strengthen the overall construction and optimize the regional layout

Due to factors such as "difficulty in land acquisition" and "low profitability", the charging infrastructure for new energy vehicles presents the actual problem of "insufficient overall construction and large regional differences", lagging far behind the scale and speed of market development. The scale and speed of market development. Because of the characteristics of charging piles such as large initial investment and long investment return cycle, it is still necessary for the government to provide necessary policy guarantee to promote the construction of charging infrastructure at this stage. Therefore, how to solve the problem of insufficient construction of charging infrastructure in general and large regional differences by turning to the financial subsidy policy is the work that the government needs to focus on for a long period of time in the future.
