To some extent, hybrid models should be the best solution for the development of domestic automobile power at this stage. Because there is no need to worry about the mileage anxiety of pure electric models, nor do you have to worry about the fuel consumption of pure fuel vehicles.
Hybrid models currently exist in the form of plug-in hybrid and oil-electric hybrid, of which the development of plug-in hybrid models in the past two years is relatively rapid, we can see that many independent brands have been laid out.
China has promised the world to reach carbon neutrality by 2060, according to the route of carbon reduction and low carbon to zero carbon, hybrid is an indispensable and most effective technology, so many car companies are committed to promoting plug-in hybrid models.
However, compared with pure electric vehicles, plug-in hybrid models that seem to solve the anxiety of endurance, in fact, most of them also have new problems. That is, most of the conditions are not fuel-efficient, and the driving experience is not satisfactory.
However, with the arrival of Changan UNI-K iDD, your traditional understanding of plug-and-mix will be subverted, what are its technical highlights?
Energy management is always online Safe and reliable no anxiety
Subject to factors such as battery weight, most of the plug-in hybrid models currently on sale have a pure electric endurance of less than 100km, making the pure electric driving mode of most plug-in hybrid models useless, and it is difficult to achieve the desire to save energy and reduce costs.
Under the condition of UNI-K iDD's NEDC, the pure electric cruising range is 130km, the comprehensive cruising range can reach 1100km, and the comprehensive fuel consumption is only 0.8L/100km. If you choose to use pure electric power for your daily commute, there is no mileage anxiety.
And if you are in the city for a long time and frequently use electricity, you do not have to worry about charging conditions. The UNI-K iDD series is equipped with 6.6kW AC fast charging and DC fast charging as standard, and supports 220V home charging function.
Of course, in addition to powering itself, UNI-K iDD also has the function of "mobile power station", which is equipped with a 3.3kW external discharge gun, which can meet the diversified living needs of users such as lighting, cooking, and reverse charging during travel, and is a super reliable helper.
Although not a pure electric vehicle, the UNI-K iDD is more stringent for system stability over the full temperature range and can be adapted to an ambient temperature range of minus 35°C to 55°C.
Among them, especially in terms of thermal management systems, a lot of optimizations have been made. The high-quality battery pack management strategy allows consumers to swim in the east, west, south and north without fear of severe cold and heat.
Even if it is not pure electric driving, you do not have to worry about the high fuel consumption problems that have occurred in the past. In order to further reduce fuel consumption and strengthen economy, the UNI-K iDD is the only one equipped with the Blue Whale NE1.5T hybrid special engine, cancels the front-end wheel train and adopts Miller cycle technology to ensure high efficiency, and achieves the ultimate balance of economy and power under the blessing of many leading technologies of the Blue Whale NE platform.
At the same time, through the advantages of A-ECMS global dynamic energy management algorithm, key components such as engines, motors, and transmissions can be maintained in the high efficiency range for a long time, and it can achieve fuel savings of up to 40% compared with the same level of fuel vehicles in the state of power shortage, and the fuel consumption of NEDC is only 5L/100km.
UNI-K iDD gives you not only a large-capacity battery, but also a comprehensive solution to the energy consumption shortcomings of plug-in and hybrid models, giving you real, reliable and undifferentiated energy management.
The power system "skill" is superior, and the full-time and all-round enjoyment of driving control is enjoyed
Thanks to advanced technology, the iDD hybrid system has the ability to adapt to the whole region. All along, everyone will criticize the plug-in hybrid model that has both electric and fuel engine power, because there are many PHEV models that are not good enough in terms of power matching.
Especially once the power is exhausted, there will be problems such as insufficient power and excessive fuel consumption, but these problems have been well solved on UNI-K iDD.
In terms of driving performance, thanks to the industry's cutting-edge technology Blue Whale iDD hybrid system, the UNI-K iDD has performed well in the full speed domain.
Blue Whale iDD hybrid system is composed of four parts: Blue Whale NE1.5T hybrid special engine, Blue Whale triple-clutch electric drive transmission, large-capacity PHEV battery and iDD intelligent control system.
Among them, the Blue Whale triple clutch electric drive transmission independently developed by Changan has a higher degree of system integration, the comprehensive efficiency of electric drive (including motor system + transmission system) is 90%, the motor power density is 10kW/kg, the motor controller efficiency is 98.5%, the hydraulic system pressure is 60bar, and the 4 technical indicators are completed beyond expectations.
Thanks to the Blue Whale iDD, the UNI-K iDD is excellent in terms of power performance in the full speed domain, with an acceleration time of 8.1s per 100 km/h. At low speed, it will start in EV mode, relying on strong torque and millisecond motor peak torque response to complete instantaneous power output and rapid acceleration. Bring users a strong sense of pushing back one step ahead.
Under high-speed conditions, the UNI-K iDD accelerates violently and can ensure long-lasting output, and the HEV hybrid operation in full gear continuously outputs maximum torque to ensure that the acceleration overtaking is full of power. Especially at a speed of 80-120KM/h, it can still maintain acceleration and bring a smooth acceleration experience to the driver at all times.
In the extreme speed state, the maximum speed of UNI-K iDD can exceed 200km/h, in the high-speed overtaking scenario, the vehicle has the ability to burst out stronger power, so as to achieve rapid overtaking, so that users feel the surging power and enjoy driving fun.
High standards and strict requirements only for the ultimate safety
When it comes to the security level of UNI-K iDD, in addition to the active and passive safety equipment that we can see, it is also very extreme in the invisible place, only to provide users with a full range of security.
During the pre-development and testing phase, UNI-K iDD rigorously tested the system for extreme high and low temperatures. At the same time, a large number of optimizations have been carried out in the thermal management system to ensure stable work in the whole temperature range.
At present, most of the PHEV models on sale use IP67 waterproof rating, IP68 is currently the highest waterproof rating. UNI-K iDD demands itself to exceed the standards stipulated by the state, only to ensure the safety of every user and family member.
At the same time, it is also equipped with a 24/7 uninterrupted battery safety monitoring system, which can ensure that the system can monitor the risk of thermal runaway of the battery 24 hours a day, even after the vehicle is powered down. It has a high-strength protection level that exceeds the national standard and a 24/7 uninterrupted battery thermal runaway monitoring function, just to prevent the danger from "unburned".
Debut is the peak, UNI-K iDD's OTA is not simple
In the past, the moment a car was purchased by consumers to go home, it was the peak moment of its "car student", but in the current view, it was only the beginning of an upward climb. UNI-K iDD also provides users with full-power domain, full-lifecycle OTA upgrades.
Among them, the full power domain includes engines, motors, batteries, transmissions, etc., in the whole life cycle will be based on user feedback, product system updates, product performance improvement and other aspects of the needs, through the OTA remote upgrade method, to ensure that users in the entire product life cycle commonly used and new, always enjoy the latest technology, so that the status of the vehicle is always online.
Not only is the vehicle and machine upgraded, but the driving control capability of UNI-K iDD can also be maintained in a state of constant upgrading, continuously providing users with the most cutting-edge and fresh driving pleasure.
Affordable and reliable "0 anxiety" to enjoy driving pleasure
UNI-K iDD is committed to realizing the multi-dimensional needs of users and providing users with a full range of "0 anxiety". In addition to having industry-leading product capabilities that work stably at full speed, full field, full temperature, and full time domains, UNI-K iDD also covers all aspects of pricing and service.
As a medium-sized SUV UNI-K iDD has entered the sequence of high-end models, and looking at the current automotive market, most of the medium-sized plug-in hybrid SUV guidance prices are above 200,000, the arrival of Changan UNI-K iDD is undoubtedly to break the price bottleneck, while the pre-sale price is less than 200,000, bringing more benefits to consumers.
The UNI-K iDD will be officially launched on March 10, and pre-sales of new cars have already begun.
As a new generation of plug-in hybrid models with the support of more advanced technology, UNI-K iDD has successfully made up for the shortcomings while inheriting its advantages, and the two dynamics complement each other.
With no range anxiety, driving pleasure and excellent energy consumption, the UNI-K iDD is arguably the most reliable and enjoyable product in the phew field, which is enough to subvert our previous perception of plug-and-mix models. 【iDailycar】
