The most headache is the battery shortage. We have discussed the battery provider, strive to get rid of the battery's insufficient supply next year, and it is expected that the sales of EVs will have a big rise. General Manager Changan New Energy Automobile Co.

, Ltd. The shortage of power lithium-ion battery is not only plagued with Changan cars, which has become a general phenomenon in the industry. Dr.

Zhang Yuxi, my country's Battery Industry Association, said that the company can process the company's company is basically unwilling to sell, the product is very good, from the industry's overall situation, the battery is not necessary will continue for a period of time. There are currently more than a thousand batteries in my country. From the quantity, the battery supply should be greater than.

However, the technical requirements and performance indicators of new energy vehicle power lithium-ion batteries are higher than those of industrial batteries and consumer electronics, and companies that can be machined from the company. The company has about ten, more famous companies have CATL, Tianjin Li Shen, Guoxuan High Class, Guangyu, etc. In the past two years, the sales of new energy vehicles have risen rapidly.

The output of these companies cannot meet market demand, what leads to the shortage of dynamic lithium-ion battery? The growth rate of the battery factory production cycle is not expected, such a high growth rate It's far from the growth rate of battery production. Wang Junqiang, deputy chief engineer of my country's Electronic Technology Group, told reporters that battery supply should not seek the original production and insufficient production, and only increase investment in this problem. However, any investment has a cycle from the beginning to the finished product, a short period of one year, long for two or three years.

my country's battery supply will continue to continue for a while. At present, many big battery plants have begun to build a new plant, which may have eased within two years. On August 20, Beiqi New Energy put into production in the total assembly workshop of Qingdao Laixi base.

According to the person in charge of the factory, around the Ledi base, will be stationed in some domestic well-known battery companies. From the construction schedule from the reporter, the battery plant in these plans will be completed around 2017. It is not difficult to see that the production cycle of the battery factory is relatively long.

In the case of the universal expansion of the battery factory, it is expected that by 2016, my country's car power lithium-ion battery production will reach 5.5 billion WH, which is 6.5 times in 2013.

A battery expert said to the reporter that under the big trend of the active expansion of the battery plant, the company is hard to take out excess energy to carry out the new battery development or technology upgrade, and will, if new power lithium-ion batteries have been admitted and industrialized, battery The versatility of manufacturing equipment is not high, and many domestic battery companies will be facing a wasteful threat. The expert proposes that the company should understand what the battery is archived, and it is necessary to understand and pay attention to what the battery will become mainstream. Another reason for the shortage of car enterprises in the car and enterprises, which is another reason for the battery shortage is too long.

Director of the Dynamic Lithium-Ion Battery Laboratory of Northern Vehicles, National 863 Electric Vehicle Major Special Power Lithium Ion Battery Detection Center Live for six to eight months to the account. He example, a famous car company has developed a new car, a set of 1 million cars, and a 76-degree electric battery is equipped with a battery. A set of batteries price is more than 200,000 yuan, more than 2 billion yuan battery models, six to eight months, to carry out more than 100 billion yuan, which battery company can bear first Tens of millions of yuan? Today, the battery company is lacking, in the case of weak money itself, no company can still take more than 100 billion yuan to pay for the previous funds, so the battery will be short in the market.

In traditional cars, the car enterprise pays the payment cycle in half a year, some or even longer. Take the engine factory as an example, a heavy truck is used for about 50,000 yuan, according to 1000 sets per single, the engine company should pay nearly 50 million yuan in advance. However, if the price of the battery and the proportion of vehicle prices, battery suppliers often have to pay up to hundreds of millions of funds in advance.

The deputy general manager of Tianjin Zhishen told reporters that the battery company is really facing such a difficulty, although this situation is better in recent time, but still exists. This year, the new energy car sales is hot. Nowadays, the car purchase battery is also used in a variety of ways.

Some will pay the prepayment, some will pay the deposit, some will have a simple pen straight home delivery. Because the battery supply is shortage, the power of the battery factory is gradually strengthening. The quality of the battery needs to be raised this year, many self-employed car companies to purchase batteries to foreign batteries.

When the reporter asked them to ask for the original, the person in charge of these car companies generally reflected that the quality of foreign batteries was better, after the group packaging, and the monomer battery was similar to the performance, charge and discharge. Domestic batteries have been lacking in quality, in the big background, the battery is not seeking, the battery is more tight. Wang Zi Winter said that he visited the battery factory abroad to find that the processing control points of all power lithium-ion batteries have a whole 1000.

Such more control points are almost astronomical numbers for domestic companies. my country's almost all power lithium-ion battery processing companies can achieve such strict quality control levels, usually dozens of control points, more, hundreds of. Zhang Yuxi also said that because in the process of domestic battery processing, some processing process parameters require no foreign counterparts, leading to the difference in product differences, and the battery difference is one of the shortcomings of the battery most taboo.

my country's processing of dynamic lithium-ion batteries, companies should master all key processes, improve battery qualification and material utilization, improve battery consistency and stability. Compared to foreign battery plants, the automation level of domestic battery processing is also to be improved. Prince Winter said that my country's dynamic lithium-ion battery manufacturing process is not real automation, just automation of each step in the process.

This semi-automatic processing method has many quality hidden dangers. In addition, my country's battery company often processes the quality of the finished product, and has automated quality testing during the process of processing in the process of processing, not only the impact of the material, but also a waste of material, saving costs. [One's words] The tragedy of the traditional car has an independent brand car company in the new energy vehicle.

In addition to BYD's self-processing battery, Beiqi new energy and South Korea joint ventures processing battery, most companies choose to purchase power lithium-ion battery processing Battery supplied by the merchant, because of the quality, performance of the battery, most of the domestic companies still more tend to choose multinational suppliers. Foreign batteries have attacked the city in the domestic market, highlighting the weak domestic battery. We are not alert, as the core components of new energy vehicles, if foreign batteries sweep the domestic company monopolized market, my country's new energy car may open the traditional car core technology hollow.

From the history of development of new energy vehicles in my country, starting to be late. In the past 15, the state immediately developed new energy automobile projects. Later, in the 11th Five-Year Plan, my country gradually identified the technical system of three vertical and three horizontal, striving to create a new energy vehicle technology system with our characteristics.

As the core component of the new energy vehicle, the power lithium-ion battery is the foundation of new energy vehicles. It is the category of any technical route that cannot be avoided, accounting for the cost of the vehicle. In the past two years, domestic dynamic lithium-ion battery manufacturers are distinguished in disadvantages with foreign battery competition.

In addition to the original origin of the battery factory itself, we should realize that the rise of the Korean battery industry is largely the results of the national strategy. This is the lack of local battery factory, because the national subsidies, the preferential policy is basically facing the vehicle factory, causing the battery factory to enjoy the remaining wave of new energy vehicle policy dividends, and there is no effort to benefit from the new energy auto market. As a machining unit of heavy assets, the power-lithium-ion battery company is often stretched in capital, the company has slowed slowly.

The parts are not strong, the whole cavity is not strong. This is the relevant experience in my country's auto people summarized in the development of my country's auto industry, and the present is more and more people who are receiving and recognized by more and more people. According to relevant surveys, in the development of automobile power lithium-ion batteries, Japan leads in technology, South Korea's largest value, although my country has huge market, but there are still gaps in other countries in terms of technology and output.

Battery's desire to develop the new energy vehicle development does not require much, if you purchase foreign batteries in your own brand, and there is basically no essential difference in the traditional car category, you will travel to the core technology industry. Today, my country has already has more battery research institutions and processing companies, processing manufacturing equipment and technology are ripening, the battery industry chain system has also gradually improved, laying the foundation for large-scale marketization development. In the future development, we should form a strong local company to create a magical competitiveness of the industry.

In this regard, national policies should focus on the company's mergers, ending the domestic small, scattered battery market pattern as soon as possible, and forming a competitive large battery company. For the socially demanding common equipment development projects, the government has introduced key technical equipment, the company participates in aggregation and upgrading, developing in advance. .
