On March 27th, in the DD-i Super Hybrid Technology Big Coffee Show held by Dongfeng Nissan Qichen, the three technical paths of Dongfeng Nissan Qichen pure electricity, plug-in hybrid and hydrogen energy were disclosed for the first time, and the technical strength of Qichen DD-i Super Hybrid was emphatically introduced. It is worth mentioning that Dongfeng Nissan Qichen will take the lead in launching the first product based on Qichen DD-i super hybrid technology-Qichen Dadvdd-I super hybrid in the first half of this year. In addition, the first pure electric product based on Qichen V-π native pure electric platform will be launched in the second half of this year.
Dongfeng Nissan Qichen DD-i Super Hybrid Power Technology
Qichen DD-i super hybrid system adopts single-gear direct-drive series-parallel technical route, which is driven by high-power motor and powered by high-capacity battery and high-efficiency engine. It is an electric-driven hybrid vehicle, which has all the advantages of electric-driven products, such as electricity and oil.
Ambient intelligence can switch driving modes according to different road conditions. For example, in urban sections, electricity is given priority to reduce energy consumption costs; When driving at high speed, switch to engine direct drive mode to give full play to the advantages of high speed and low fuel consumption; When braking, kinetic energy will be recovered as battery energy storage. Qichen DD-i super hybrid power system adopts low-temperature energy transfer control technology, which can realize power output and unloading, solve the problems of battery and vehicle performance attenuation and high-speed stall in cold environment, and improve vehicle power.
In addition, Qichen is still actively exploring hydrogen energy technology and plans to promote the commercialization of pilot projects this year. Hydrogen energy technology is a forward-looking technology, which has the characteristics of green, high efficiency and safety, can be hydrogenated and charged, and is an all-green energy power scheme.
Qichen big V DD-i super hybrid model
Power system level: Qichen V DD-i super hybrid adopts the hybrid power system of 1.5L engine and motor, and the output power of the engine and motor can reach the maximum power of 140kW and the maximum torque of 230n·m, which makes the vehicle have stronger power and acceleration capability, and lower fuel consumption and emissions. Technically, the system can realize the energy consumption strategy of saving more electricity, using less oil, giving priority to pure electricity and using oil efficiently. The fuel consumption per 100 kilometers is 4.3L, the comprehensive fuel consumption is 0.85L, the comprehensive cruising range exceeds 1000km, and zero acceleration can be completed in 7.9 seconds.
Energy-saving level: Qichen intelligent electric hybrid system adopted by Qichen V DD-i super hybrid, which can be used for electricity and oil, intelligent dual drive, adapt to different road conditions and realize intelligent switching of drive modes. In urban sections, the system can give priority to power consumption, ensure vehicle performance and reduce energy consumption; In the feeding state; The engine generates electricity through the generator to drive the wheels and charge the battery at the same time. Step on the accelerator, the engine generates electricity, and the battery discharges, which makes the acceleration response faster; When driving at high speed, the system will switch to the engine direct drive mode to give full play to the advantages of high speed and low fuel consumption; In addition, Qichen V DD-i Super Hybrid super hybrid power adopts an energy recovery system, which converts kinetic energy generated by vehicle movement into electric energy for storage through braking and inertia, reducing energy waste and improving energy utilization.
Battery energy storage level: Qichen V DD-i Super Hybrid Super Hybrid is equipped with an efficient battery energy storage system, which can store energy and release it when necessary to provide power for vehicles. In addition, the battery system also has intelligent management function, which can be intelligently adjusted according to the driving situation of the vehicle and the driving habits of the owner, so as to maximize the service life and stability of the battery.
Control system: Qichen V DD-i super hybrid adopts intelligent control system. Through the adjustment of intelligent control system, the working modes of engine and motor can be automatically switched according to factors such as vehicle speed, driving habits and road conditions, so as to achieve the best energy utilization and vehicle performance. For example, its car. E The single pedal system can intelligently match the acceleration and deceleration algorithm according to the scene requirements and working conditions, and the same pedal can realize smooth switching of acceleration and deceleration, simplifying driving operation, reducing the operating frequency of specific scenes by 50% and improving the comfort by 30%. At the same time, thanks to the blessing of Nissan's high-performance sports chassis and the combination of high-performance suspension and full-frame subframe, Qichen V DD-i Super Hybrid adopts sports-style chassis adjustment, which makes driving more stable, steering more sensitive and bumpy roads easy to cope with.
Intelligent configuration level: Qichen big V DD-i super hybrid also has intelligent welcome mode, the virtual key of smart phone is started with one button, and the lighting/sound/dynamic effect is intelligent welcome; Match the ODS function of the unique seat at the same level, start without feeling, get on the bus with electricity, and reduce driving steps. In addition, Qichen DD-i Super Hybrid is also equipped with a number of intelligent configurations, such as intelligent voice control, intelligent navigation, and car WIFI. These configurations can improve the driving experience and driving safety. At the same time, the vehicle is also equipped with active safety configurations such as adaptive cruise, lane departure warning and automatic emergency braking.
As the world's largest automobile market and new energy market, the hybrid power market is blooming. Many powerful China brand car companies have launched their own hybrid technologies, such as BYD DM-i, Great Wall DHT and Geely Raytheon Hybrid. In this activity, Dongfeng Nissan Qichen revealed the three major technical paths of pure electricity, plug-in hybrid power and hydrogen energy, showing forward-looking and advanced nature. As the first product of Qichen DD-i Supersoul Technology, with the blessing of hard-core technology and the tonality of young products that Dongfeng Qichen brand has been pursuing, I believe that the new car will bring more surprises after its debut.
