Is the revolutionary breakthrough in battery power just a slogan?

The executive meeting of the State Council held on February 24, 2016 determined measures to further support the new energy automotive industry and promote green development through structural optimization. The meeting proposed to accelerate the realization of a revolutionary breakthrough in power batteries. Promote large-scale small and medium-sized enterprises, universities, and research institutes to establish collaborative power supply innovation platforms for collaborative research and openness, and focus on the development of key materials, battery systems, and common technologies. The central government adopts the award-subsidy method to reward enterprises based on performance indicators such as battery performance and sales volume. Increase support for the digital manufacturing of complete sets of equipment for power batteries.

So how do we view the attitude of the government's senior management of new energy vehicles, especially pure electric vehicles?

First of all, from the point of view of pure electric vehicles that are currently on the market and sold in bulk, their basic cruising range averages 250-300 kilometers, with 150-200 kilometers at the low end and 350-400 kilometers at the high end. The charging time is generally 6-8 hours for slow charging and 80% for fast charging.

Second, the problem of low temperature and failure of the battery is still outstanding. On the one hand, in the cold regions of the north, and even in the winter, even with full power, the vehicles cannot run the proper mileage; on the other hand, with continuous use, the battery pack rapidly decays year after year. Two years may only be able to run 80%, and even in the third year can only run 50%.

The executive meeting of the State Council proposed a development goal for power batteries and should be said to be at the heart of the matter. However, what is a "revolutionary breakthrough" has yet to see any authoritative interpretation.

One understanding is that in the future, the power battery of new energy vehicles has made breakthrough progress in terms of endurance, charging time and exhaustion rate. The mileage of a single electric vehicle is equivalent to that of conventional fuel vehicles of the same level, and the charging time is from the current hour. Turning to minutes, it still has a minimum of 85% electrical energy after several years of use, which is certainly a perfect ending.

Another understanding is that although the battery life and charging time have not been substantially improved, the safety of the power battery has been effectively improved, and the fire and the like have not occurred due to frequent plugging and unplugging. This has created a future power battery replacement mode. good conditions.

Of course, if in the foreseeable future, not only can the battery life of the battery be improved, the charging time can be significantly shortened, and at the same time its safety can be more reliable, it is even more perfect!

However, there is always a gap between the ideal of good and the reality of bone. The general meeting of the State Council mentioned the need to coordinate the strength of universities, research institutes, and enterprises. The general direction should be extremely correct. Concentrating on major issues is the greatest advantage of our socialist system with Chinese characteristics. However, how to achieve the openness and sharing of innovation platforms is difficult to achieve and do under the market-oriented environment. How to solve the problem of division of labor among universities, research institutes, and enterprises in related R&D? How should the expenses be shared? Who owns the ultimate related intellectual property? The company has changed to “substitute for awards” to avoid fraudulent actions, but how can we prevent potential fraudulent subsidies at the tertiary institutions and research institutes?

In addition, on the face of it, universities and research institutes should assume more of the task of research, but for practical products, it is more a process of system integration and data accumulation. At this time, companies may be more powerful and leave the company. Whether or not the participating R&D can ultimately be commercialized is problematic.

In the end, which companies can participate? Is it only the car companies that can participate, or can they intervene as long as they are willing? Is it because the country builds one or several platforms, or is it that different companies and different institutions establish R&D alliances, which are widely used to collect revenue? This may involve the beginning of the issue of how to design and arrange top-level products on the supply side.

As some regions currently exclude hybrid vehicles from new energy vehicles, as a transitional product of traditional fuel vehicles, hybrid vehicles can not only maximize the use of existing resources, but also reduce waste. At the same time, it can also reduce the use of traditional fuels and reduce emissions. Therefore, if we cross the threshold of hybrid vehicles too aggressively and directly develop pure electric vehicles, the new energy vehicles are still not finalized in the technical route. Although the direction of vigorous development of the power battery is good, but the results can be achieved, Really worrying. It is hoped that "achieving a revolutionary breakthrough" is not merely a slogan of passion. In the early stages of the development of new energy vehicles, the experience and lessons of the so-called "curve passing" strategy put forward by relevant government departments should be learned!
