The future of power battery needs multi-dimensional development. Comprehensive development can win market recognition.

On the afternoon of May 3, the “China Automotive New Silicon Valley 2018 Yangtze River Delta Future Automotive Supply Chain Innovation Forum” hosted by the GNEV official organization and hosted by the first electric network was held at the Shanghai Audi International Circuit Sky Restaurant. Hongtao Yu, Chairman of Carne New Energy According to a keynote speech on "Development Trends in power battery Technology", the evaluation criteria for power batteries are multi-dimensional. The specific energy is not the main indicator for evaluating power batteries. It can be fully recognized in terms of safety and service life to win market recognition.

Speaking of the future trend, Hongtao Yu proposed that the evaluation criteria of power battery is multi-dimensional, and specific energy is not the main evaluation index, because the specific energy depends on the material, and the material can be used to the extreme to achieve 300Wh/kg, even 310Wh/ Kg, but as a battery, it is also an important research and development direction to ensure safety, cycle performance, high temperature performance and low temperature performance in the case of high specific energy.

Previously, Professor Minggao Ouyang proposed that enterprises can achieve 300Wh/kg than energy, but the cycle energy is only one week. This is meaningless. The whole evaluation of the power battery should be multi-dimensional. It is very dangerous to look at only one of the dimensions, and it is unscientific and cannot really enter the market. It is also necessary to explore safety, charge and discharge performance, life, cost, quality, recyclability, industrial chain, and continuous innovation capabilities. These conditions determine the market competitiveness of battery companies.

For the research and development direction of the performance of Ka Nai, Hongtao Yu said that the first is safety, the experiment of overcharging, acupuncture and drop for the electric vehicle use scene to ensure that the battery can cope with a variety of unexpected situations; the second is the specific energy, He said that the current chemical level is difficult to distinguish between high and low, but the key is who can increase the specific energy to achieve industrialization; the third is in terms of service life, the test of battery usage should not be only in constant temperature, short-term recycling In the case of the case, it is necessary to ensure that the power battery can still be used normally under high and low temperature and long-term placement, and the quality guarantee of the card is 300,000 kilometers.

In terms of cost, Hong Tao said that the battery industry has been bitter in recent years. The national policy has been adjusted every year, not only in the battery industry, but also in the new energy industry. A new car is generally a 36-54 month period. However, the new energy vehicle will give you a maximum of six months, and in the second half of the year, it will develop new products. There is also a significant reduction in subsidy costs. In terms of comprehensive statistics, the average subsidy in 2015 was 2.4 Yuan/WH, in 2016 it was 2.1 Yuan/WH, in 2017 it was 1.7 Yuan/WH. In 2018 it was 1.35-1.45 Yuan/Wh.

Finally, Yu Hongtao expounded the development plan of Carne, the first is to adhere to the soft package, because Ka Nai believes that the soft package is the safest, the balance is the best, the future service life is guaranteed. The second is to build a research and development base, an overseas center and five production bases. The third is to build core competitiveness, to meet customer requirements in terms of safety, quality, cost, technology, delivery, etc. The fourth is an innovative business model that enables battery companies, OEMs and end users to form a complete community of interests.
