It is expected that the number of charging piles worldwide will reach 14 million units in 2025, and the market size will exceed one trillion US dollars. Taking Liuzhou, Guangxi, China as an example.
The background of the high proportion of household pure electric vehicles in Liuzhou
Liuzhou is located in the hinterland of Guangxi. It is the second largest city in Guangxi and an important industrial town in the southwest region. In addition to the amazing scenery and culture, Liuzhou’s new energy automobile industry is also amazing. Statistics show that for every 100 vehicles used by households in Liuzhou, 22 are pure electric vehicles; in the past five years, the electrification rate of urban household cars has also been increasing year by year. As of now, the electrification rate of Liuzhou passenger cars has reached 33. 1%, ranking first in the country.
Liuzhou government and enterprises collaborate to support the development of charging industry and charging facilities
In the context of the current large number of household pure electric vehicles in Liuzhou City, how to ensure the normal charging of a large number of household pure electric vehicles is a matter of great concern. The "News Live Room" column of CCTV News Channel once had the title "Liuzhou, Guangxi, improves public supporting facilities and creates a "Ten-Minute Charging Circle"", and the "Zhengdian Finance" column of CCTV Finance Channel once had the title "Find a charging pile in 10 minutes!" "Reducing the "Charging Difficulty" of New Energy Vehicles in Liuzhou, Guangxi" was titled "Liuzhou, Guangxi Province" and reported that owners of household pure electric vehicles can find charging piles to charge their cars in Liuzhou within 10 minutes. Relevant municipal departments have taken multiple measures to create the "Liuzhou Model" for the promotion and application of new energy vehicles through government-enterprise linkage, supporting promotion and market-driven methods, and have successfully opened up a path for "production, sales, and production" in the promotion and application of new energy vehicles. New ways to use, stop, recharge” and other services. During the last five-year plan, the Liuzhou government had already established a leading group for the promotion and application of new energy vehicles. A series of relevant policy documents that are conducive to the development of new energy vehicles and the charging industry have been promulgated, aiming to encourage relevant companies to continue to Increase investment in talent and capital and speed up the construction of charging piles and charging stations.
The development status of household pure electric vehicle charging methods in Liuzhou
Field visits and surveys and relevant data show that the charging method for household pure electric vehicles in Liuzhou is mainly based on fast charging at charging piles, supplemented by battery swapping.
Currently, more than 700 public charging pile sites and more than 9,000 charging piles have been built across the city; more than 530 public charging socket sites and more than 20,000 charging sockets (including personal charging sockets, incomplete statistics). The number of public charging pile sites has exceeded the number of gas stations. More than 30,000 charging piles and charging sockets have been built, with a vehicle-to-pile ratio of 3:1. In addition, Liuzhou has also selected areas to build new new energy vehicle charging station demonstration projects. Currently, 66 demonstration institutions, 64 demonstration schools, 36 demonstration enterprises, 35 demonstration communities, 22 demonstration commercial areas, 6 demonstration hospitals and 2 demonstration roads have been promoted and copied from point to area, and the service network and service system of charging pile charging have been continuously improved. In August 2021, Liuzhou's first power swap station was officially put into operation at the Liuzhou Lushan Comprehensive Energy Service Station of China Southern Power Grid. Here, in addition to plug-in charging, household pure electric vehicles of the corresponding brand can also be swapped and charged.
Conclusion
The development and progress of charging methods is related to the actual experience of thousands of households when using pure electric vehicles. In the final analysis, it is a people's livelihood project. Based on the charging frequency of household pure electric vehicles 1 to 3 times per week, and the above description and comparison of several charging methods. Taking Liuzhou as an example, the current development status of household pure electric vehicle charging in Liuzhou was analyzed, and the current development status of household pure electric vehicle electric energy supplementation methods is summarized as follows: At present, the charging method of household pure electric vehicles in my country is mainly plug-in charging. For ordinary home users, plug-in charging is the most competitive charging method based on many current factors, especially fast charging. The development trend of electric energy replenishment methods for household pure electric vehicles is: fast charging at charging piles is the main method, and multiple charging methods coexist. This trend will continue for a long time to come.
In response to the above trends, the following three suggestions are put forward:
a. The state should continue to increase policy support for the new energy vehicle charging industry, be policy-oriented, clarify the development direction, and actively strengthen government-enterprise cooperation, improve the design and planning of charging infrastructure, and establish a reasonably distributed power energy system. Accelerate the construction and layout of fast charging piles and listen to suggestions from all parties to provide strong backing.
b. Relevant companies are continuing to improve and explore technologies such as fast charging, power batteries and electric operation, constantly reducing fast charging time and reducing the damage caused by fast charging to power batteries. For new charging methods such as battery swapping and wireless charging, appropriate investment should be made, research should be improved, and small-scale pilots should be conducted to store energy for technological breakthroughs in a few years.
c. Actual users of household pure electric vehicles should develop good car usage and charging habits. For example, try to use the vehicle within the power range of 20% to 90% of the power battery, try to avoid overcharging and discharging, and extend the service life of the vehicle. Have a good car experience.
