The world's first single super large capacity lithium power battery bus

On November 12th, 2014, in the 12th Michelin Bibendum Challenge, the world's first super-capacity 500AH lithium power battery pure electric bus was launched. The only two awards were won by the bus group and the innovation group, which caused Chinese and foreign guests and media. Wide attention.

In order to allow readers to further understand the single-capacity 500AH lithium power battery pure electric bus, the author is honored to interview Mr. Wang Xiaogong, President of Beijing Shenzhou Judian New Energy Technology Development Co., Ltd.

Throughout the interview, Mr. Wang Xiaogong repeatedly emphasized to the author: "Battery is the soul and core of electric vehicles. The reason why China has not been able to realize large-scale industrialization of electric vehicles is, in the final analysis, the safety and economic problems of batteries. ""

The world's first single-capacity super-capacity 500AH lithium power battery pure electric bus, the "Shenzhou giant electric" single-capacity large-capacity solid polymer power lithium power battery. Wang Xiaogong said: "Our single-capacity high-capacity solid-state polymer power lithium power battery, compared with the usual small-capacity battery, we solved the problems of battery pack heating, battery pack real-time monitoring, etc. Usually the small-capacity battery needs to pass the battery pack. Parallel to obtain capacity, so the internal resistance of the battery is increased, the heating phenomenon is common, and ventilation or even liquid cooling is required. The single-capacity large-capacity battery greatly changes the battery performance, making the internal resistance smaller, the heat generation during use is less, and the battery box even No ventilation and cooling design is required, and its unique solid-state form can avoid accidental liquid leakage and the resulting safety accidents."

The "Michelin Bibiden Challenge" has gradually become a mature "thought and action" think tank, inviting cutting-edge ideas and technologies to show and even compete on the same stage. "Shenzhou Jupower" single-capacity solid-state polymer power lithium power battery became the only representative of the global new energy electric vehicle battery was invited to be selected.

"This pure electric bus, in addition to low power consumption, there is a point that I can dynamically detect the battery status in real time, the professional introduction is the battery module security active power management system (ABMS) real-time monitoring technology. In real-time status Next, the parameters including the voltage, electric quantity, temperature, internal resistance, charge and discharge of the single battery are controlled within a safe range, and the battery pack for processing the dispersion variation is repaired at any time. In addition, the smart battery cell is in a sub-health state of the battery. Send out an alarm message to avoid a vicious accident. We can monitor the health of the battery whenever and wherever there is, and take precautions." Mr. Wang Xiaogong confidently told the author.

Industrialization is the insurmountable key to the transfer of technology to human productivity. Users can afford not only the important issues that buyers and operators consider, but also the issues that producers must consider. Wang Xiaogong said: "The operating cost of an ordinary diesel vehicle is usually 600-700 yuan per day. The operating cost of a single super large capacity 500AH lithium power battery pure electric bus is 60-70 yuan per day, which is equivalent to one tenth of traditional energy. After-sales, 8 years of contract management ensures safety and economy."

"The industrialization process of Shenzhou Judian is accelerating. Shenzhou Judian has launched a battery-free maintenance contract for eight years. It will replace the maintenance and repair of the battery within eight years, so that users have no worries." Wang Xiaogong told reporters. “Battery is a specialized product, and its maintenance is also professionally technical. We don’t need to let users learn such complicated expertise. As a battery producer, we have the ability and conditions to monitor all processes after the battery is shipped. From factory monitoring, to operational monitoring, to recycling monitoring to ensure reliable life-cycle."

Wang Xiaogong is a typical science and technology worker. On May 24, 2014, President Xi Jinping emphasized during the inspection of Shanghai Automotive Group: "The development of new energy vehicles is the only way for China to move from a big automobile country to a car power. To this end, he is deep. Encouraged, he believes that under the policy of the country's strong support for new energy vehicles, the mission of battery technology workers is to achieve battery safety and economical level of commercialization, to achieve breakthroughs in battery technology, and to help Chinese buses and even Chinese cars. Technology is the world's leading sequence.
