Zhang Tian-ren: power battery industry should strive to achieve "pole vault"

The development of new energy vehicles in China Summit Forum on the eve of the reporter an exclusive interview in Shanghai, China Latitude D500 Battery Industry Association, vice chairman, managing director of day to day any of the battery group.

This is not a reporter and Zhang days of first contact office. Last year in May, he was in Hangzhou to this reporter's interview made three points: the Chinese battery company not sell ourselves short; should be set for our use of global resources; development of new energy vehicles, the development of battery industry, must not engage in "Great Leap Forward" . The pertinent words, is impressive. The re-interviewed in Shanghai, Zhang days of any new energy to our car and battery development of the industry once again delivered a unique insight. In his view, the development of new energy vehicles, priority is to develop science and technology development in the battery line, and along this route "along which the bar" for development of the "pole vault."

Technical route choice problem as well as key

"China Automotive Report": In your opinion, China's new energy vehicles to achieve industrialization, the most urgent need to address what the problem is?

Zhang Tian-ren: new energy vehicles is the core of competitive technologies, the most pressing is to achieve a breakthrough in battery technology. Looking at the present, including hybrid, fuel cell and electric vehicles, including electric cars, new cars more viable laptop battery energy technology options. Key components in electric vehicles among the highest battery of technical barriers is the most concentrated part of the profits. If you can not grasp the core battery technology, new energy vehicles in China are destined to suffer "ceiling." The breakthrough in battery technology, no doubt that pierce the "ceiling" of the "bamboo", as China entered the field of new energy vehicles, seize the commanding heights of the best starting point for the future of the industry.

"China Automotive Report": Some experts now believe that we have with Japan in battery technology, there is a big gap between the United States. You have said that a "Chinese battery company not sell ourselves short," point of view, we and the developed countries there is much difference in the end?

Zhang Tian-ren: In recent years, developed countries especially the great progress in battery technology in Japan. From 1975 to 1990, 15 years, improved battery energy density 1.8 times; 1990 to 2005, the battery energy density enhancing the cross of a 5.2-fold. According to the Japanese government issued a "plan of action for the next generation of vehicle fuel", 2015, advanced battery performance than the 2010 level of 1.5 times, lower costs to the current 1 / 7. Fuel cells is still a hot research and development, the life of the current fuel cell stack compared to 2003 increased more than twice the cost of the fuel cell system has been reduced to 2002 1 / 3. China is the world's major production and consumption of battery power, we have the world's largest market,Inspiron 600m but the technical level and the developed countries there are still gaps that should be recognized. But we also lies in a greater gap between the management and equipment, manufacturing processes and patents and so on.

"China Automotive Report": a lot of battery types, such as lead-acid, nickel hydrogen and lithium ion batteries, lithium batteries which there are many types. Which should be chosen for the technical route, and now very controversial, how do you think?

Zhang Tian-ren: the development of car battery, in the end what technology should be given priority routes, has been a controversial topic, the government, enterprises, investors and consumers are confused. 25 day laborers in June 2009 letter issued by the Ministry of the "new energy automobile manufacturers and product access management rules," the new energy automotive products were divided into initial stage, development stage, mature stage of the three different technologies, including fuel cell vehicles an initial stage, the development of lithium battery electric vehicles are used lead-acid and nickel-metal hydride batteries for electric cars are mature products. I think it should be to the car battery technology specified in a route choice more scientific way. Inspiron 510m Business policy environment and a guide can make scientific battery technology development path, and along this route "along which the rod" and achieve "pole vault."
