AutoBeta(AutoBeta.net)10/24 Report--

"tough talk" seems to have become a compulsory course. Deng Chenghao, CEO of Changan New Energy, said in an interview a few days ago: "the advantages of traditional joint venture fuel vehicles are gone, and the last straw that kills them is PHEV and extended range." At the same time, Deng Chenghao also said, "surpass all the joint venture fuel vehicles, only the dark blue SL03 extended range version, not one."

Changan Deep Blue SL03 is the first new energy vehicle of Changan Deep Blue Brand. It was officially launched on July 25. The new car has launched four models with a price range of 16.89-699900 yuan, of which the extended-range version is priced at 168900 yuan, the pure electric version is priced at 18.39-215900 yuan, and the hydrogen version costs 699900 yuan. As the first model under the Deep Blue SL03 brand, the new car is based on Changan's new EPA1 pure electric platform and is positioned as a medium-sized car. The main competitors include Tesla Model 3 and BYD Seal. However, Deng Chenghao believes that, "Changan Deep Blue SL03 extended version of the main target competition is the joint venture brand of fuel vehicles."

In terms of power, the new car uses a variety of different forms of drive system, including pure electric, extended range version and hydrogen version. Among them, the pure electric version provides two motor versions, 160kW and 190kW, with integrated mileage of 515km and 712km respectively, while the extended version is equipped with a drive system based on 1.5L engine and motor, and the comprehensive mileage of the system is 1200km when the comprehensive mileage of pure electric mode is 200km.

Objectively speaking, pure electric vehicle is the mainstream route of automobile development in the future, but it does not mean that the added model has no value. From the perspective of the current market, in addition to ideal cars and Selis, Lantu cars, zero-running cars, Skyline cars, Naha cars, Changan Deep Blue and self-travelers have all launched add-on models, which has further led to the rapid growth of Zengji car sales.

In fact, the large-scale influx of add-on models into the new energy vehicle market is mainly reflected in two aspects: first, there are more and more new entrants and additional players; second, the policy level continues to increase tilt. In November, 2021-2035 New Energy vehicle Industry Development Plan issued by the General Office of the State Council also clearly pointed out that plug-in hybrid vehicles, pure electric vehicles and incremental fuel cell vehicles should be regarded as "three verticals". Layout of China's automobile technology innovation chain.

Although the add-on program is a backward technology, it is almost the most in line with the current vehicle environment. The power system of the new energy vehicle is generally composed of the battery system, the drive system and the control system, while the incremental vehicle has one more range expander than the pure electric vehicle.

The function of the extender is similar to the engine of the fuel vehicle, but the extender can not drive the car directly, its working principle is: when the power supply is sufficient, the power battery drive motor provides the car drive, and the range extender does not participate in the work; when the power consumption reaches a certain extent, the range extender starts and charges the power battery, but when the power is sufficient, the range extender stops working and continues to be driven by the power battery drive motor. To put it simply, the add-on car is equivalent to carrying a range extender on the pure electric vehicle to achieve the purpose of extending the mileage.

For a long time before this, add-program technology has been in a marginal position, even criticized as "outdated technology", but according to the market performance of the current mainstream ideal L8, ideal L9, M5, M7 and other models, these models have performed well in their respective levels and are among the best in the new energy vehicle market. Therefore, whether the technology is outdated, there is no standard for consumers to buy cars, in line with the needs of consumers, will be recognized and supported by the market.

Plug-in hybrid technology, which is relatively close to the add-on technology, has extremely high technical barriers, which requires not only the engine and gearbox of fuel vehicles, but also the power batteries, motors and electric controls of pure electric vehicles, but from the current market performance, only BYD performed relatively well.

As for the development of add-on technology, is there any future? There is no doubt that before the range of pure electric vehicles and the number of charging infrastructure have not been greatly increased, add-on technology is still an effective solution for large-scale replacement of fuel vehicles to achieve the goal of "double carbon" at this stage. However, it is not easy to replace the fuel car market. Of course, the development circumstances of different brands are different. Take Changan Deep Blue as an example, its extended-range version is finally priced at 169800 yuan, and the price range of 10-200000 yuan is still dominant in the fuel vehicle market. It is almost impossible for Changan Deep Blue to surpass all traditional fuel vehicles.
