Three standards for electric vehicles to activate scale comments
January 19 the Ministry of public request for "electric vehicle requirements of IGBT module environmental testing and test methods" industry standard 233 other national standard reviews of 10 projects. Of which there are three electric industry standards for vehicles, namely "environmental testing requirements for electric vehicle IGBT modules and test methods", "methods of measurement system noise motor drive electric vehicles and limits "," electric vehicle charging EMC requirements coupled system and test methods ".
Standard integration to accelerate
It is worth noting that the three electric vehicles will be a unified industry standard, namely "environmental testing requirements IGBT modules electric vehicle and test methods", "electric vehicle unit of measurement methods and limits system noise motor "," cargo vehicle electrical coupling system EMC requirements and test methods ".
Standard specification is the basis for industrial development. Ministry sources, in recent years, organizations of business sectors to increase investment in industry, actively promoting the development of standards for electric vehicles and building the system. So far, China has published 75 standards for electric vehicles, the establishment of a more perfect standard system of electric car, based on common standards between vehicle and 28, battery 21 and a standard keyboard unit, standard facilities 26 load, covering all aspects of electrical development needs of cars. Such as charging interface with national standards has been released, the application of national unity, the electric car can be charged at any battery charge.
Market participants said that with the rapid development of the electric car industry, uniform standard pace is accelerating. At present, the authorities are willing to change the rules 77, 16. Standards revised standard battery life cycle previously required the full release after 500 cell attenuation shall not exceed 20%, and now the index increased 10%. As a rule to guide and promote and improve battery performance, battery life can do the same for the life of the vehicle. With the continuous improvement of the performance standards of growing products, consumers will greatly facilitate the concern of new energy vehicles.
Scale activation
"The purpose of standardization, the first is the market need for standards, ie market access, market management requires standards; the second is to regulate the industry to improve product quality, reduce product costs, for economies of scale. "National Automobile Standardization Technical Committee Chairman of the Technical Committee of electric vehicles, said Wu Zhixin.
At the origin of the industry chain grasp the right to speak standard system, no follow design is certainly very beneficial. With many known foreign car companies have entered the Chinese market, such as BMW, Nissan and Tesla and other foreign car companies designed to use their own standards, which the United States claims along the Beijing-Shanghai high-speed Tesla build their super-charging stations.
With the production, access and other gradually unified standards, the new scale energy automotive industry is expected to appear. Before November 2014, Development and Reform of the National Commission issued the "Interim Provisions automakers pure electric passenger new investment projects and the production and access management (draft)" in the notification. According to the notification, new car companies independent legal pure electric passenger, you need at least three years of research and development base of pure electric passenger vehicles, master control system, power battery systems, integration vehicle and vehicle weight reduction technology base and verification capabilities corresponding test requires the production capacity of vehicle testing, and is capable of electric batteries for cars, engines, systems electrical control and other basic components of not less than 5 years or 100,000 km warranty, a sound system sales and after-sales service.
