5-minute charging life a thousand kilometers? Hainan "magic battery " provoke questions 1
 

"A mobile phone vanadium battery, charger, 3 to 5 minutes, continuous use of one and a half; a vanadium battery electric vehicles, charging 3 to 5 minutes and a range of up to 1,000 kilometers, while the cost of lithium batteries cost only 40% of the current volume and weight are the lithium battery 1 / 25 and 1 / 10 ... ... "

    This is Hainan media imported from Germany and efficient introduction of vanadium battery project. There really such a good battery? Can really achieve this technology? If you really can achieve such a "bull" effect, what it failed to promote a wide range of it?

    Germany to the magic battery

    April 20, Hainan Provincial Government and the Bonn Investment Co., Ltd., Germany TUG New Transmission Technology Co., Ltd. signed a strategic cooperation framework agreement in the next 5 years, Bonn, Germany, TUG will join the project and international brands and companies and institutions in Hainan to investment is not less than 120 billion high-performance V-scale implementation, including the four projects, including battery power.

    It is understood that the inventor of this technology is a professor of German scientists Koplin, now he has completed the process design of the new vanadium battery and module production, this year will come out a template vanadium battery.

    Hainan, according to local media reports, according to estimates, after 3 to 5 minutes of charging, the vanadium battery life on the ability of the car can reach 1,000 km; if used in mobile phones, can continue to use a half months. More attractive, this cost is the cost of lithium batteries, 40%, respectively, lithium battery size and weight of 1 / 25 and 1 / 10, can be recharged more than 12,000 times the battery life of up to 20 years.

    Industry: Germany did not use the public

    "According to my understanding, Volkswagen's new energy vehicles are still using a lithium battery, should there be such a good technology, why not their own but to the Chinese use?" Long-term concern about the new energy automotive industry experts, Jiangsu Changshu together Environmental Energy Technologies Institute of the Public Changsha Yongkang told the "Daily Economic News" interview, said, puzzled.

    In fact, according to the above argument, a calculation of the average charge per day, 12,000 times the number of repeated charge can make the battery life of up to 32 years. A car by 10-year average life span, a the vanadium battery can be used continuously for 3 cars.

    Yong-Kang Sha, says that most small electric vehicle power consumption of 1,000 km 150 kwh to 200 kwh, if you want the full 3 minutes, and under normal operating voltage of electric vehicles do not calculate more than 500 volts, then the charging power requirements of equipment 4,000 kilowatts, the charge current of 8000 amps. The general current of 2 amps TV, washing machine current is 3 amps.

    Yongkang suspected of sand, "charging 3 to 5 minutes," the statement may be accomplished by replacing the electrolyte. The working principle of vanadium battery is the power stored in the electrolyte, to loop through the electrolyte. Yongkang sand that, if the vanadium battery used in these portable devices, using the bumps in the process would seriously affect the battery performance.

    National Energy Research Institute researcher at the Center for Renewable Energy Development Jing Li when told the "Daily Economic News" interview, also said that at present the main use of vanadium batteries power wind power and photovoltaic power generation in the above, have not heard used in mobile phones and the car example.

    Industry experts also pointed out that, due to relatively low energy density, and temperature adaptability of the problem, vanadium battery can not be applied to the current car. If true for cars, there will be half the space vehicle occupied by the battery and the car will not start a winter dawn, noon, summer, battery scrap and so on.

    Yesterday (May 5), the reporter called the Propaganda Department of CPC Hainan Provincial Committee, hoping to interview with investment by the Propaganda Department to contact the company vanadium battery, but the publicity department said it was "business secret" to disclose.
