The electrification of automobiles currently seems to be an irreversible development direction, after all, the efficiency of the electric motor in converting electrical energy into mechanical energy is much higher than the efficiency of the internal combustion engine in converting internal energy into mechanical energy. However, at this stage, electric vehicles are subject to problems such as battery density and charging efficiency, and the convenience of use is still far behind that of traditional fuel vehicles, so various automobile manufacturers have successively launched many gasoline-electric hybrid models. Although independent brands have a good development in the field of pure electric vehicles, there have been some mature products in the field of hybrid vehicles in the past one or two years, after all, hybrid vehicles should save fuel, and they are inseparable from an efficient and fuel-saving engine.
Since it comes to the development of independent brands in the engine field, it is necessary to mention Changan Automobile, the Blue Whale series engines they use in fuel vehicles, and the power and fuel consumption performance are very good. A few days ago, Changan launched the Blue Whale NE1.5T hybrid engine on the basis of the 1.5T Blue Whale engine, and launched the first plug-in hybrid model equipped with this engine, UNI-K iDD. So what are the characteristics of the UNI-K iDD equipped with the Blue Whale NE1.5T hybrid engine? Let's take a look at it together.
Efficient hybrid system
Since the UNI-K iDD is a plug-in hybrid model, the core is the power system. The power system of UNI-K iDD consists of four parts: Blue Whale NE1.5T hybrid special engine, Blue Whale triple-clutch electric drive transmission, high-capacity PHEV battery and iDD intelligent control system. This powertrain performs well in "full speed domain", "full field domain", "full temperature domain" and "full cycle".
The "full speed domain" is well understood, and the UNI-K iDD performs very well at different speeds. Thanks to the addition of high-efficiency motors, the EV mode is adopted, at which time the advantages of fast response and large torque of the motor will be exerted, and the vehicle can be quickly accelerated; under high-speed working conditions, the HEV hybrid mode can be used to maintain the maximum torque and make the overtaking more relaxed.
"Full field" is the performance in different scenarios. The UNI-K iDD has a pure electric endurance of 130km and a comprehensive endurance of 1100km. Of these, 130km can be used to meet the daily commute in EV mode when charging conditions allow. At the same time, UNI-K iDD is also equipped with 3.3Kw external discharge equipment, which can meet the diversified living needs of users such as lighting, cooking, and reverse charging during travel.
The "full temperature range" is the dynamic performance at different temperatures. The excellent attenuation control strategy of the Blue Whale iDD battery pack adopted by UNI-K iDD can adapt to the ambient temperature range of minus 35 °C to 55 °C, so that the vehicle's power battery is not afraid of severe cold and heat.
"Full cycle" means that UNI-K iDD provides an excellent product condition throughout the entire life cycle. This is first of all due to Changan's excellent quality assurance, and the system will continue to implement intelligent, remote full-power OTA upgrades, from the software level to keep the vehicle in a good operating state.
How does UNI-K iDD do the above four things? This has to be mentioned by the Blue Whale NE1.5T hybrid special engine, Blue Whale three-clutch electric drive transmission, large-capacity PHEV battery and iDD intelligent control system composed of four parts of the Blue Whale iDD hybrid system.
Blue Whale NE1.5T hybrid engine, this engine first uses a lower fuel consumption Miller cycle, and has undergone many electrification upgrades, so that the engine thermal efficiency has been improved, so that fuel consumption is further reduced.
Blue Whale triple clutch electric drive transmission, UNI-K iDD equipped with Changan independent research and development of blue whale triple clutch electric drive transmission, the biggest advantage of this system is mature and reliable technology, high efficiency. Mature and reliable is mainly reflected in the three-clutch system is currently the mainstream plug-in hybrid vehicle used in the transmission program, BBA and other high-end brands are also in use; high efficiency is mainly reflected in the motor, UNI-K iDD This motor uses S-winding winding technology, can have higher motor power density, higher motor efficiency.
Large-capacity PHEV battery, UNI-K iDD is equipped with a 30.74kWh ultra-large capacity battery pack, with better endurance performance, while for the natural hidden dangers of the battery is the use of ultra-national standard high-strength protection level and all-weather uninterrupted battery thermal runaway monitoring function.
iDD intelligent control system, good hardware is only the foundation, a good set of control system can play the advantages of hardware to the fullest. This system can combine navigation information to determine road driving conditions (such as congestion or unimpeded), and distribute power in advance to achieve better energy savings. It also integrates multiple subsystems such as engines, motors, batteries, and transmissions, so that they are all in the most efficient working area, and have achieved optimal economy. Of course, this system also supports OTA remote upgrades.
The Blue Whale iDD hybrid system makes UNI-K have a very good performance in power, and UNI-K, as a plug-in hybrid model, also has its own unique features in human-computer interaction. The vehicle has a variety of driving modes to choose from, and users can choose according to different car environments, supporting custom modes. The HMI design on the instrument allows users to better understand the vehicle status, and combined with the dominant vehicle information of the car model, it looks more intuitive.
Vehicles can also be charged in the car or using the app reservation, and charged at night in the valley of electricity charges, thus effectively reducing the cost of use.
The exclusive App can also display the battery charging status in real time, the type of charging gun, the remaining time of charging, the remaining power of the power battery, the electronic lock status of the AC gun, the status of the charging cover, etc., so that the user can grasp the charging situation in real time.
"Out of Bounds" design
UNI-K iDD also adopts the UNI family's very iconic borderless grille, and uses a parametric method to use a hexagon matrix to present a sense of technological fantasy, the elements of this hexagon are reflected in all aspects of vehicle design, the appearance is there, the interior is also there, such as knobs, cup holders, etc. are hexagonal design.
"Out of line" configuration
The configuration level of UNI-K iDD can be described as out of line, and the safety configuration has parallel assist, lane keeping, and active braking
Active safety configuration, but also equipped with a number of driver assistance configurations, such as full speed intelligent adaptive cruise, transparent chassis, 540 ° surround view, L2 level of driving assistance is not a problem. In terms of comfort, there are zero gravity seats, SONY headrest speakers, in-car air monitoring, air purification and other systems, and high-performance braking systems ensure the braking efficiency of the vehicle. The rich configuration makes the UNI-K iDD easy to open and comfortable.
The space for "out of the loop"
UNI-K iDD as a branch of UNI-K, naturally also has a length of more than 4 meters 8 and a wheelbase of nearly 2 meters 9, in the medium SUV is not a small size, which provides a basic guarantee for ample interior space, and the second row of UNI-K iDD floor is still flat, which not only improves the space utilization but also improves the comfort of the rear passengers.
UNI-K iDD's Blue Whale iDD hybrid system is already very good in the current plug-in hybrid model, fuel consumption and power are very good guarantees. And UNI-K iDD is born from the UNI-K model, UNI-K originally has a high value, high configuration, large space have been well inherited, it can be said that UNI-K iDD is a very much worth looking forward to plug-in hybrid new model.
