Behind the “Great Leap Forward” in the power battery industry

A group of data released by GGII shows that since 2015, new investment in the field of power batteries has exceeded 100 billion yuan, and the number of domestic power battery companies has also soared from 50 at the end of 2014 to nearly 150 in 2016. , increased by nearly 3 times.

Power Battery

Of the more than 100 newly-added companies, there are traditional digital batteries that have been transformed from the upstream and downstream, as well as real estate, steel, fire protection, and home appliances.

Where there is light, there is a shadow, and under 300% growth rate, there are hidden chaos and crisis: The phenomenon of “digging foot” has increased rapidly, safety issues have been frequent, the risk of low-end overcapacity, product copying and imitating... these may be destroyed at any time. Going out of the industry "landmines." In all kinds of chaos, digging up the walls is the most common cause of criticism in the industry, and it is also the root cause of potential safety hazards and product imitating plagiarism.

The quick success of capital has led many newcomers to not have the patience to do the training of talents and the establishment of a corporate employee system. Instead, they have attempted to solve the immediate needs by digging into the first-tier companies.

"With short-term, profitable thinking, some indiscriminate fish and irresponsible outsiders are trying to establish a team quickly through the method of "digging at the foot of the wall." However, the role of the excavated team is often only a small number of engineers who go out and change to become the chief workers."

Luo Huan-t found that many so-called “total workers” did not understand the design system and only knew a little about product design. “Because of the lack of systematic understanding, the products produced by these companies ignore the concept of safety, plus many Seizing the market at a low price has severely disrupted the healthy development of the industry and has caused a very negative impact."

Digging the wall has become a common practice, indicating that the industry is too impulsive. Similar to Luo Huanta's experience, Wang Dong, the director of the Northern Vehicle Supervision and Testing Institute (201 institutes) and the evaluation expert of the “Automotive Battery Regulatory Industry”, evaluated the current power battery industry with the word “Float”.

The most serious consequence of impetuous rafts is frequent safety incidents. The preliminary statistics of high-tech lithium power grids indicate that up to now, there have been more than 20 domestic auto accidents for new energy vehicles. In Prince Dong’s view, the main reason for causing a safety incident is the lack of technical R&D accumulation and practical application experience of power battery companies.

And if we go deeper and deeper, behind the short board of technology research and development is the lack of talent team building and systematic system.

In fact, the power battery as the heart of new energy vehicles, it is self-evident for the safety of the vehicle, to achieve the power system security, it involves the matching of materials, batteries, group structure, battery management system, powertrain , vehicle environment, operation management, and plenum management, and many other dimensions and dimensions.

The solution to security problems and technological breakthroughs require companies to establish a strong talent and technical team. The power battery industry is an industry with equal emphasis on technology and experience. It requires a large number of high-end technical talents who have long been engaged in the industry. In addition to good professional knowledge and strong comprehensive design capabilities, technical personnel also need to have rich practical experience.

In Luo Huan-t's view, the idea of ​​relocating one or two core talents to allow companies to quickly stand up has always been just wishful thinking. Many companies that once held this vision finally discovered that the so-called “shortcuts” are tantamount to quenching thirst. It is not possible to fundamentally solve the core issues that companies face such as technology and management, but also missed the best time for the establishment of a talent system.

“The accumulation of experience is the process of long-term running-in and precipitation. It is difficult to cultivate a group of professional technicians and professional management teams that have sufficient design, development expertise, and rich experience. It takes at least five years Accumulation of running-in, no shortcuts."

Taking the power battery PACK link as an example, the core technologies include the customized development technology of the battery management system, thermal management technology, current control and detection technology, module assembly design technology, aluminum alloy power battery outer box casting technology, and computer virtual development technology. And so, if there is no such core technology, the PACK link only completes the assembly process and it is difficult to produce products that are different from other competitors.

Many power battery companies do not have the system reserve of PACK technology at all, and many simply build a production line by digging one or two engineers from a large company. Such results are naturally conceivable. Due to the lack of a deep understanding of system safety, it leads to its ultimate The product has a huge security risk.

According to Prince Dong’s analysis, the fire of new energy vehicles is mainly focused on electricity and heat. During the R&D process, enterprises in various fields such as batteries, packs, motors, electronic controls, and vehicles are generally lacking in profound technology accumulation. The product development process is not Perfection, mainly to meet the basic functions of the new energy vehicles and parts of the characteristics did not fully study, especially in the safety function design process if not effectively guaranteed, led to the thermal runaway of the battery pack.

This means that if the company simply solves the safety problem of the entire power battery system in a short period of time by digging people, it is basically impossible, and if the market continues to tolerate the products of companies that lack technology research and development to disrupt the industry, the consequences will be disastrous.

From the macroscopic point of view of the development of the power battery industry, Luo Huanta’s proposal is to cope with the current chaos in various aspects such as policy supervision, industrial self-discipline, and corporate self-awareness. At the policy level, the government can use the The rules and regulations for setting up the directory require specific requirements for technical research and development and teamwork. In the blank areas of policy supervision, spontaneous “hide rules” can be established among domestic power battery companies, creating a black and white list of companies and talents. The circumvention of chaos.

“From the point of view of the development of the power battery companies, the technical team and the systematic development system are the cornerstones of the company's development. Enterprises must be absorbed in practical accumulation. Too many cases have warned us that the recognition is unrealistic and we are lucky to have it. The shortest way to the end, you will find that it is actually a dead end to death," said Luo Huan-tower.
