Introduction: Starting from the second half of 2021, the hybrid technology of the domestic automobile market is slowly blossoming, no longer a monopoly or that each technology is similar, and the unique technology with brand characteristics has gradually emerged, such as Nissan's e-POWER, the GREAT Wall system's DHT, Geely Raytheon Power, BYD DMi, etc., all of which make people shine, so what are the different shining points of these new technologies?
The author of the previous article also briefly introduced to you why the domestic hybrid system has sprung up like a mushroom in the past two years, and more is the reason for policy and market demand. And today, with the listing of Changan Automobile's UNI-K iDD, I will introduce you to Changan, which has a good performance in the engine field, how about this hybrid system it brings?

Before that, let's briefly introduce UNI-K iDD, the new car has launched a total of two models, the official guidance price of 176,900-19.29 million yuan, respectively, excellent and noble. Compared with the pure fuel version with the same configuration level, that is, the 2.0T all-wheel drive excellent model is only 0.8 million yuan more expensive, to tell the truth, in this batch of hybrid models, its price is still very competitive.
And it is worth mentioning that Changan is still very satisfied with this shape of UNI-K, and the hybrid version has not been adjusted. The exterior design of the whole vehicle is very avant-garde, similar to the scaly mesh with the series of headlights, it looks very avant-garde, of course, you can also think of it this way, Changan's UNI series model itself looks like a new energy model, so it is completely reasonable not to make changes.
There is no change in the car, the overall design is very avant-garde, the special-shaped steering wheel needs an adaptation time for most users, and the combination of the suspension central control and the full LCD instrument is also very technological. Although the battery and motor have been added, the internal structure of the UNI-K iDD has not changed, so the space performance in the car is still excellent.
The power part, I believe is also the part that everyone is most concerned about, the new car equipped with this blue whale iDD hybrid system was released at the 2021 Chongqing Auto Show, this system is composed of high-performance blue whale engine + high-efficiency blue whale electric drive transmission + battery + intelligent control system four parts. First look at the effect, the official introduction of its even in the state of power, its 100 km fuel consumption is as low as 5L, for this size of SUV is already quite good.
First take a look at this more efficient Blue Whale series engine, Blue Whale series engine domestic users are very familiar with, the two years in the domestic popularity is very high, and the new Blue Whale iDD engine integrated into the Agile agile combustion system, on the basis of our familiar Blue Whale NE1.5T engine, combined with intelligent thermal management, Miller cycle, intelligent lubrication and a series of technologies, so that it has higher thermal efficiency. According to Changan, in the next 5 years, this engine will continue to evolve and increase the thermal efficiency to 45% to achieve more economical goals.
Of course, the core is this electric drive transmission, which is also the core of Changan's second-generation hybrid platform, which is compatible with PHEV and HEV. This transmission uses a three-clutch P2 module, which is also a model favored by major brands on the market. It also has four core technologies: high-efficiency high-pressure hydraulic system, intelligent electronic double pump technology coupling, S-winding winding technology, and triple clutch integration technology.
According to official data, the overall efficiency of this transmission is 90%, the maximum sales volume of motor controllers exceeds 98.5%, the motor power density reaches 10 kW/kg, and the hydraulic system pressure is as high as 60 bar. It also allows the maximum transmission efficiency of the Changan Blue Whale iDD system to reach 97%, and with the 1.5T Blue Whale engine, the system has a total torque of up to 590 Nm.
Then there is the battery, the blue whale iDD hybrid system is equipped with a battery pack with a capacity of 30.7kWh, pure electric mileage up to 130km, equipped with AC and DC dual fast charging technology, the whole series is equipped with 6.6kW AC charging, and can also be discharged externally, the discharge power is 3.3kW, which is now a lot of small partners who like camping, this discharge power and capacity are very sufficient. So this is also the reason why the author thinks that UNI-K iDD is only 8,000 yuan more expensive than the ordinary version of the same configuration.
The ability to keep the whole vehicle in the feed state and maintain low fuel consumption, in addition to the above several elements, is not unrelated to the Blue Whale iDD intelligent control system, which can make the engine, electric drive transmission, and battery work together in the optimal area, and the fuel saving effect of the feed state is more than 40%.
summary
First of all, as the first model of the Changan Blue Whale iDD hybrid system, UNI-K iDD still has a lot of sincerity in terms of price, after all, if you want to promote the hybrid system, you can't let users spend too much price, and this is where it has more advantages over Weipai and Xingtu. If you are a first- and second-tier city, the license plate and car cost pressure are relatively large, choose Changan's hybrid system is still very wise and cost-effective.
