The Development Of New Energy Vehicle Charging Industry Faces Four Major Challenges

In the first half of this year, my country's new energy vehicle sales reached 4.944 million units, a year-on-year increase of 32%, and the market share has steadily increased to 35.2%. Along with the simultaneous growth in new energy vehicle sales, the increasingly popular charging infrastructure is also growing. Data shows that as of June this year, the cumulative number of charging infrastructure in my country has reached 10.243 million units, a year-on-year increase of 54%, which can basically meet the charging needs of more than 24 million new energy vehicles across the country. The number continues to increase, but complaints such as "difficult charging" and "unreasonable charges" still occur from time to time, and the road to building a high-quality charging infrastructure system needs to be further explored.

 

 

 

Zhou Libo, deputy secretary-general of the Electric Transportation and Energy Storage Branch of the China Electricity Council, said that with the development of the industry, my country's charging industry has formed a multi-technical development route of conductive charging, battery replacement, and wireless charging. The diverse energy replenishment methods together constitute a high-quality, three-dimensional charging system. Among them, technologies such as supercharging and battery replacement are developing rapidly. With the development of autonomous driving technology, wireless charging will also be further promoted. my country's charging infrastructure construction has gone through a process from scratch, from slow charging to fast and slow, and from high-speed development to high-quality development. It is currently in the process of transforming from "being able to charge" to "charging well". "She said.

 

However, while applauding the progress of the industry, we must also see the problems in development. Liu Yongdong emphasized that the current charging industry still has problems such as incomplete layout of charging and swapping facilities, unreasonable structure, unbalanced services, and inadequate operation. At present, the development of new energy vehicles in my country is still in the early stage of large-scale promotion. Charging facilities are facing the development of new energy vehicles and the needs of power grids. The upstream and downstream of the industry must form a development consensus and jointly promote the high-quality development of the charging industry. Our product Aluminum Housing For Lithium Battery can provide stability for the development of electric vehicles and promote the large-scale development of new energy vehicles.

 

As Liu Yongdong said, a high-quality charging infrastructure system should not only consider the interests of consumers, but also focus on the healthy development of charging companies. Tianyancha data shows that as of now, there are nearly 594,000 companies related to charging piles. The development is relatively scattered, the levels are uneven, and the fierce price competition has made many charging companies complain. Relevant surveys show that 51.92% of charging operators are suffering from price wars, which has greatly damaged the healthy ecology of the charging industry.

 

In this regard, Chen Haiqiang, chairman of China Southern Power Grid Electric Vehicle Service Co., Ltd., said bluntly: "The competition in the charging industry is very fierce. Everyone is "rolling", "rolling" services, and "rolling" prices. Operators "rolling" upstream will compress the profits of charging pile manufacturers, and the prices of charging modules are also constantly pressing down." In his view, if the upstream and downstream industrial chains of an industry are "rolling", it will be difficult for industry enterprises to make profits, which will be detrimental to the layout and sustainable development of high-quality charging networks. The industry needs to work together to create a mutually beneficial and win-win industry ecology. Aluminum Battery Box For Electric Car is made of high-quality aluminum alloy, which provides good guarantee for the development of new energy vehicles and high-quality charging infrastructure.

 

The background of high-quality development is green development. If the charging industry wants to form new quality productivity, it will undoubtedly accelerate the pace of interaction between electric vehicles and power grids. Since the beginning of this year, relevant policies such as the "Implementation Opinions on Strengthening the Integration and Interaction of New Energy Vehicles and Power Grids" have emerged in an endless stream, bringing huge opportunities for the growth of the vehicle-grid interaction (V2G) industry and new growth points for charging companies trapped in the vortex of internal circulation. However, facing the realistic difficulties in scale, technology, standards, etc., V2G development still needs time.

 

Wang Wen, deputy general manager and party committee member of State Grid Smart Internet of Vehicles Technology Co., Ltd., believes that my country's vehicle-grid interaction is still in its early stages, lacking market mechanisms and mature technologies, and has not yet formed normalization and scale. In addition, the most regulatory private pile resources have not been fully utilized and aggregated. In this regard, he suggested that the basic role of the price mechanism in vehicle-grid interaction should be fully utilized to guide consumers to charge in an orderly manner.

 

In May this year, nearly 1,500 new energy vehicles responded to the peak-shaving needs of the power grid through "orderly charging" and "reverse discharge" at different stations in Shenzhen, successfully realizing the largest-scale vehicle-grid interaction application in the country. According to Chen Haiqiang, this practice proved the feasibility of V2G technology, but also found several problems in large-scale promotion.

 

First, in terms of discharge willingness, new energy vehicle owners are generally anxious about the battery damage caused by discharge. Chen Haiqiang said that due to the lack of an objective evaluation system for the impact of discharge on batteries, and the lack of a complete warranty plan on the part of car companies, new energy vehicle owners are somewhat anxious about discharge. Our product Aluminum Case For LiFePO4 Battery Pack is used in various types of batteries, which plays a role in ensuring the smooth discharge during the use of the car.

 

Second, in terms of transaction varieties, the current vehicle-grid interaction is mainly based on precise response on the demand side. From a technical perspective, it is difficult for charging piles to respond in terms of frequency modulation, which also leads to the participation model being mainly based on peak-valley price difference arbitrage. "If the transaction varieties are limited to demand-side response, it will not lay a good foundation for the long-term development of vehicle-grid interaction." Chen Haiqiang said. In his opinion, the subsequent transaction varieties, number of participations, and participation methods need to be further improved.

 

Third, in terms of the standard system, there is no unified standard for the agreement between new energy vehicles and V2G charging piles, and even different models of the same car company may have different agreements, which makes it difficult to promote on a large scale. In this regard, Chen Haiqiang suggested that industry standards should be formed as soon as possible in the standard system between new energy vehicles and V2G charging piles, especially in terms of interactive interfaces, update protocols, and power regulation.

 

 

In the hundred-year development history of the automobile industry, "safety" has always been the bottom line and lifeblood of industrial development. Entering the era of new energy vehicles, the importance of safety is also unshakable. In recent years, new energy vehicle charging fire accidents have occurred frequently, arousing public concern about the safety of new energy vehicle charging. In Zhou Libo's view, with the large-scale construction of supercharging equipment, the industry needs to further strengthen the bottom line of safety. Aluminum Alloy Prismatic Battery Housing has a good protective effect on the performance of the battery when charging, and can provide good corrosion resistance and hardness.

 

From the perspective of power batteries, Ma Xiaoli, deputy general manager of Guolian Power Battery Research Institute Co., Ltd. and executive deputy secretary-general of China Automotive Power Battery Industry Innovation Alliance, believes that the industry should not excessively advocate fast charging, but should return to calmness, and should not pursue fast charging and super charging in one step, but first stabilize the 3C strategy, then do a good job of the 4C strategy, and step by step develop in the direction of super charging.

The so-called "charging safety" is a process in which any relevant party involved in the charging process is not in danger, harmed, or has no accidents. Therefore, charging companies also need to assume the responsibility of ensuring charging safety. Wang Wen said that "easy to find stations", "easy to use charging piles", "fast charging" and "safe charging" are the four key points to improve the user charging experience, among which "safe charging" is the bottom line. He believes that charging companies should build a charging network that is more convenient than refueling on the premise of safety.
