Three measures to promote the solution, the Ministry of Industry and Information Technology responds to the low temperature of electric vehicles

At the '2020 Industry and Informatization Development Conference' held a few days ago, Huang Libin, spokesperson of the Ministry of Industry and Information Technology and Director of the Operation Monitoring and Coordination Bureau, answered reporters’ questions about the low-temperature 'pawo' of electric vehicles and raised questions. Three solutions.

Huang Libin said that in recent years, with the continuous improvement of technological level and the optimizing of supporting environment, new energy vehicles have been recognized by more and more consumers, and the market scale has gradually expanded. Compared with fuel vehicles, electric vehicles have the advantages of energy saving and emission reduction, low use cost, convenient maintenance, power, and controllability. However, the industry is still in the development stage, and there are still problems such as high vehicle costs and inconvenient charging. , Low temperature environment performance degradation is also one of the problems. It is mainly manifested in the obvious performance degradation of power batteries in low-temperature environments, the reduction of battery capacity, and the reduction of driving range. Especially in the recent cold wave and temperature drop in northern cities, the problem has become more prominent, and consumers have also responded to this to some extent.

'It should be said that this is a problem that has arisen in the development of emerging industries. It needs and can only be solved by a higher level of development. We believe that with the improvement of technology and the improvement of management policies, new energy vehicles Low-temperature performance will definitely be substantially improved.' Huang Libin said.

The problem of low-temperature use of electric vehicles is related to the vital interests of consumers. The Ministry of Industry and Information Technology organizes vehicle and power battery companies, industry institutions, and universities to carry out technical research to accelerate the research and development of low-impedance film-forming additives, all-climate batteries, etc. And industrialization to improve the low-temperature driving performance of electric vehicles. Recently, an expert seminar was organized to promote the solution of this problem and proposed three measures:

The first is to require auto companies to strengthen after-sales service and promptly resolve user demands. Organize industry organizations to strengthen popularization of science and guide scientific use.

The second is to support vehicle companies and battery manufacturers to strengthen technological research, improve low-temperature driving performance of electric vehicles, and improve user experience.

The third is to study and formulate relevant technical specifications, accelerate the promotion and application of Chinese working conditions, clarify the performance and technical requirements of low-temperature environment products, and strengthen product access and production consistency inspections. At present, key enterprises and industry institutions have taken active actions to release winter car guides, increase after-sales service forces, and deploy scientific and technological research projects.
