Shulou(Shulou.com)12/24 Report--

According to the news released by the Federation of passengers, the retail volume of China's new energy passenger car market reached 767000 in October, an increase of 37.5% over the same period last year. The sales volume and growth rate of plug-in plus extended range demonstrate that their growth rate is greater than that of the new energy market as a whole. There is no doubt that the position of new energy vehicles in China's automobile market will be more stable.

Thanks to the advantage of "no endurance anxiety", plug-in hybrid technology and extended range hybrid technology vehicles in the new energy technology category have become a popular choice for consumers. Because of this, the debate about "which is better or worse" between plug-in hybrid and extended-range hybrid technology has never stopped.

It is believed that every new energy user has been entangled and studied in the face of these different routes of new energy technology.

Intermingle with or extension, in fact, this is not a judgment question, but a "mixed multiple choice question".

Here, the author might as well do a simple popular science.

What is plugging in? What is extended range? The engines of traditional fuel-fueled cars and current hybrid cars can be driven directly. The so-called plug-in hybrid combines the advantages of pure electric vehicles and traditional fuel vehicles, in which the engine can participate in power generation (series), vehicle driven by motor, or direct drive (parallel). Drive the vehicle alone or with the motor.

Add-on cars, to put it simply, are externally rechargeable, built-in engines, and driven by pure electricity. Among them, the built-in engine of the add-on car can only be used to generate electricity, not directly drive the car.

Regardless of other technical points of view, the technical structure of the extended range hybrid is simpler, and the plug-in hybrid structure is more complicated. after all, the plug-in hybrid engine can also participate in direct drive and has two sets of power systems, while the add-on program has only one power system.

Therefore, in terms of power output, plug-in hybrid vehicles have four modes: EV, series, parallel and direct drive.

Because the engine does not participate in direct drive, there are only two kinds of extended range hybrid: EV and series.

The engine of plug-in hybrid vehicle can directly participate in driving the car without intermediate energy conversion. Plug-in hybrid vehicle can ensure good high efficiency and low fuel consumption performance in a variety of road conditions, including urban roads and highway roads. In expressway and highway mode, the fuel economy of plug-in hybrid vehicles is higher than that of extended-range hybrid vehicles.

Under the condition of high speed, the extended range hybrid car needs to be powered by the engine burning oil continuously, and then transferred to the motor to drive the car. After an energy conversion in this process, it is not as efficient as the direct drive of the engine, and the fuel economy is slightly inferior to the "plug-in hybrid".

Therefore, consumers can feel the most intuitive point at the experience level: in urban road conditions, their final fuel consumption gap will not be too big, but if in continuous highway conditions, extended range hybrid cars often lead to the problem of "high fuel consumption" because of "power loss".

This is also the most obvious advantage of plug-in hybrid technology in terms of energy efficiency. Therefore, we can add a conclusion here, extended range mixing can be said to be a "simple version" of plug-in mixing, which is the optimal solution to take into account both urban experience and high-speed fuel consumption.

Plug-in hybrid, higher technical threshold some new power brands in addition to the pure electric route, will also choose to add program hybrid technology. In essence, add-program hybrid is equivalent to pure electricity + add-on. Plug-in hybrid requires a special engine, as well as a series of complex technologies such as electric mixing system, so relatively speaking, plug-in hybrid requires a higher technical level, and the threshold for entry will be higher, of course.

At the previous expert media exchange meeting of the China Electric vehicle 100 people Forum (2023), Ouyang Minggao, academician of the Chinese Academy of Sciences, professor of Tsinghua University, and vice president of the China Electric vehicle 100 people Association, once explained in detail, "you have to say that the technical threshold must be high, so generally new car builders will not choose plug-in mixing."

In the choice of technical route, most of the automobile brands with technology accumulation choose the plug-in hybrid route, and the plug-in hybrid technology is gradually occupying a dominant position in the new energy vehicle market. One of the most representative is BYD, whose DM-i super hybrid technology is already a household name. The rapid growth of plug-in hybrids is largely due to BYD. as the leader in plug-in cars, BYD sold 123000 DM-i models in June, accounting for nearly 60% of the entire plug-in market. In October, BYD sold 135590 DM models, up 18.6 per cent from a year earlier.

One of the core components of BYD's DM-i super hybrid system, the engine specially built for DM-i super hybrid technology, once won the title of mass-produced gasoline engine with the highest thermal efficiency in the world with 43 per cent thermal efficiency.

For automakers, add-program hybrid is a low-threshold, low-cost technology with significant cost advantages, but in fact, many extended-range hybrid models are more expensive than plug-in models of the same class. Behind this, on the one hand is the advocacy of public opinion, in fact, it is the lack of cost control ability of the relevant car companies.

For ordinary consumers, it is not a question of right or wrong to add or. After all, each specific product has its own advantages and applicable scenarios, comprehensive competitiveness, including security, comfort, technology configuration and other comprehensive strength.

In any case, the new energy market is developing very fast. In a short period of ten years, China's auto market has ushered in earth-shaking changes. In the days when joint venture brands were in their heyday, consumers had no choice of automotive products, but now they are "unable to choose". Isn't this a great progress?
