Winter is undoubtedly the most headache time for many pure electric vehicle users. Whether it is a new energy vehicle equipped with lithium iron phosphate or ternary lithium, in the cold winter season, the endurance will be greatly attenuated, the mileage anxiety will be greatly improved, and the pure electric vehicle will become "electric daddy" in winter.
How to say goodbye to the problem of endurance anxiety, while having relatively low energy consumption, there is no limit to the problem of limiting the number of cards, then the hybrid system is undoubtedly the most pragmatic choice at present. Therefore, we can see that car companies are now developing their own corresponding hybrid technologies to cope with market trends. For example, BYD's DM-i and Great Wall's DHT are hybrid technologies that have attracted more attention in recent years.
As the current strength of Chinese brands, Changan Automobile also officially released its hybrid system , Blue Whale iDD Hybrid - in June last year. At the same time, after half a year, Changan Automobile's Blue Whale iDD hybrid was finally mounted on the mass production model and officially met with consumers, which is UNI-K iDD.
100 kilometers of fuel consumption of 5L, the most economical in the same level
First of all, let's understand what the Blue Whale iDD hybrid system is such a hybrid system.
Blue Whale iDD hybrid system technical name is the global intelligent oil-electric dual-drive system, including high-performance Blue Whale engine, high-efficiency Blue Whale electric drive transmission, ultra-large capacity PHEV battery, intelligent control system, can be applied to A-C class models.
The so-called "global domain" includes four meanings: "full speed domain", "full field domain", "full temperature domain" and "full time domain".
"Full speed domain", which means that this hybrid system can ensure an instantaneous power explosion and a comfortable driving experience in low-speed starting, high-speed overtaking, and extremely high-speed tracks. Its initial acceleration can reach 0.6g, zero hundred acceleration takes more than 6 seconds, and the top speed easily reaches 200 kilometers per hour. Moreover, regardless of the level of power, its acceleration ability is equally prominent. It does not decay because of electricity.
"Full field" is for the car scene, the city commuting pure electric mode, the mileage can reach 130 kilometers, which is already a new record for the current PHEV models on the market (battery power reaches 30.7 degrees); long-distance, battery power is abundant under the comprehensive fuel consumption of only 0.8 liters / 100 km, even if the power is lower than the SOC limit (power state, also known as B state), fuel consumption is only 5 liters / 100 km, the maximum cruising range of 1100 km.
"Full temperature range", that is, this hybrid system can work normally from a very low ambient temperature of minus 35 ° C to a very high ambient temperature of 55 ° C.
"Full time domain" refers to providing users with stable durability throughout the life cycle, as well as a lifetime upgrade of the full-powered software package OTA.
So having said all this, what is the level of Changan's hybrid system in the industry?
Let's take the most direct fuel consumption indicator as an example. Toyota Highlander's 100-kilometer comprehensive fuel consumption is 5.3-5.8L; the bydirum Tang DM-i equipped with super hybrid system has a power consumption of 5.3-5.5L/100km; and the official fuel consumption of the Great Wall WEY Mocha Plug-in Hybrid edition is 5.7L/100km. In contrast, the Changan UNI-K equipped with the Changan iDD hybrid system has a weight of 2 tons of SUV, but the comprehensive fuel consumption of 100 kilometers of power loss is only 5L, which can be said to be the lowest in the same class.
In addition to energy saving, in terms of performance, it is also equipped with a 1.5T engine, by WHICHD Tang DM-i zero hundred accelerated for more than 8 seconds, while Changan only needed more than 6 seconds (the system's comprehensive torque was 590 Nm). It can be seen that from the two core indicators that users are most concerned about, Changan's hybrid system is completely handy in terms of book strength.
How does this fuel economy work?
Seeing this, many people will wonder, why is Changan Blue Whale iDD hybrid technology so strong? Here we have to talk about the hardware and technology of this system.
Changan Blue Whale iDD hybrid system includes high-performance Blue Whale engine, high-efficiency Blue Whale electric drive transmission, ultra-large capacity PHEV battery, and intelligent control system.
Among them, the engine, the iDD hybrid system adopts the Blue Whale 1.5T hybrid special turbocharged engine, the maximum power is 126kW, the maximum torque is 260 Nm, and within 5 years, it will also use new technologies such as variable valve lift system and variable-section electronic turbine, so that the thermal efficiency of the engine will reach 45%.
In terms of the most core electric drive transmission of the hybrid system, the iDD hybrid system has 4 core technologies for the first time in the industry, the most important of which is the S-winding winding, which can improve the efficiency and power density of the motor system, which has won the PACE International Award. Coupled with highly integrated wet three-clutch module, high-efficiency high-pressure hydraulic system coupled with intelligent electronic dual-pump technology, four-stage filtration technology of less than 5 microns, IGBT double-sided cooling technology, etc., it makes it the world's most advanced electric drive transmission.
Specific to the parameters, Changan's electric drive transmission 4 indicators are the first in the industry: the comprehensive efficiency of the electric drive is 90%, the maximum efficiency of the motor controller is more than 98.5%, the motor power density is 10kW/kg, and the hydraulic system pressure reaches 60 bar.
In terms of batteries, the iDD hybrid system is equipped with a large capacity PHEV battery pack with a capacity of 30.7 kWh, and the pure electric cruising range can reach 130km. In terms of charging, all models equipped with this hybrid system will be equipped with 6.6kW AC charging as standard and provide 3.3kW external discharge function.
In terms of intelligent control system, the iDD hybrid system takes the lead in realizing the mass production application of A-ECMS global dynamic energy management algorithm. The system has a number of independent research and development technologies such as multi-core parallel operation architecture, A-ECMS energy management algorithm, full power domain OTA, power attribute customization, etc., and the power saving effect of the power state is more than 40%.
It is based on these powerful hardware and technical advantages that the iDD hybrid system has the leading performance and fuel consumption level in the same class.
By the way, it is worth saying that all the above technologies, Changan has complete intellectual property rights.
Science and technology Chang'an launched the battle for electrification
Everyone says, "Honda buys an engine to send a car", this sentence also applies to Changan. A very important reason why many users choose Changan Automobile is that it values its core component, Blue Whale Engine, in the industry.
As an important part of Changan Automobile's Shangri-La strategy, as early as 2016, Changan CS95 was equipped with a Blue Whale 2.0T engine. Until 2019, the Blue Whale Power brand was officially released to the public and began to be known to more and more consumers. Moreover, with excellent performance, fuel consumption performance, and product quality, it has been recognized by consumers and the industry, and various engine awards have also been won.
Today, the arrival of the iDD hybrid system will not only further strengthen the brand image of "Technology Changan", but also announce that Changan Automobile has officially entered the "2.0 electrification era". At the same time, for friends with endurance anxiety, it is undoubtedly a major industry gospel. On the one hand, there is no worry about charging, but also energy consumption. And in terms of performance, it is also further than traditional power. Coupled with the super benefits of the green card, the iDD hybrid system is undoubtedly in line with market and policy developments.
Therefore, we have reason to believe that with the popularity of the Blue Whale iDD hybrid system, it will also help Changan Automobile achieve more eye-catching sales results under the wave of electrification.
