R&D progress of xiaokang new energy vehicle: the energy density of battery system is higher than 160Wh/kg

May 11, xiaokang shares in an investor survey revealed its investment in the new energy vehicle business and development planning.

In China, the company has set up chongqing jinkang new energy automobile co., LTD. (" jinkang new energy "for short) and obtained the production qualification of pure electric passenger vehicles, according to the company. At present, jinkang new energy is building a digital plant, which is expected to be completed in the second half of 2018. At present, the 1.5 billion yuan raised by the company's convertible bonds is being invested into jinkang new energy as planned. In the United States, SFMotors, Inc. The acquisition of AMGeneralLLC, an American automobile company, further improved the company's layout in the manufacturing process to create a leading brand of smart electric vehicles. Tell me about your acquisition of InEVit, Inc., an American battery systems company. In addition, the company will further consolidate its technical strength and talent team in the field of intelligent electric vehicle battery system.

In terms of research and development achievements, in March 2017, xiaokang company held a press conference in the global innovation highland silicon valley of the United States, and for the first time released to the world the company's achievements in electric drive technology, three-power system integration and intelligent driving system, and released two major vehicle platforms, SF5 and SF7.

1. The company has developed ac asynchronous motor with high power density and high energy density. The maximum speed of the motor is 16000rpm. Company motor product power density 5. 5Kw/Kg, and the current industry leading level of 3. 0 to 4. 0 kw/Kg.

2. The company has developed integrated products of motor, high-speed gearbox and motor controller, which have the advantages of small size and light weight. The company has developed a unique water-cooled oil-cooled double-loop cooling system, which is in the process of patent application. In addition, the motor controller adopts IGBT packaging technology, which has the advantages of high reliability, high power and low cost.

3. Double motor design system developed by the company, without mechanical differential; Motor controller source code program design, to achieve instantaneous control of torque, provide four-wheel drive torque output, for safe driving to bring efficient power and better performance control.

4. At present, the company mainly engages in cell purchase and sales with international battery enterprises, and purchases single cell 4. 8-5. 0Wh high energy density 21700 cylindrical cell; The company has developed a unique end-cooling battery system PACK technology, which is in the process of patent application. The energy density of battery system is 160Wh/kg, while the industry leading level is 150Wh/kg.

5. The company develops the technology application and system integration of "protective autonomous driving" and independently developed gateway system, which can provide safe and stable data protection and realize the update of air software (OTA).

In terms of research and development investment, the company's intelligent electric vehicle research and development layout is "two countries and four places", to build two large vehicle research and development centers in North America and Asia Pacific, silicon valley sandian intelligent research and development center and Beijing sandian intelligent research and development base. In 2017, the company spent $8 billion on research and development. 1.2 billion yuan, accounting for 4. 16 percent, a big increase from 2016. It mainly includes two parts. The first part is the r&d expenditure for new SUV models. 2 billion yuan, up 1 percent from 2016. 7.5 billion yuan; Second, the company's research and development spending on smart electric vehicles 2. 9.7 billion yuan, up 1 percent from 2016. 5.3 billion yuan.
