Hybrid or range-extended electric? A 'hybrid multiple-choice question' that's not just about technology

According to the news released by the Passenger Car Association, the retail sales of my country's new energy passenger vehicle market reached 767,000 units in October, a year-on-year increase of 37.5%. The sales and growth rate of plug-in extended range prove that the growth rate of the two is greater than that of new energy vehicles. In the overall energy market, there is no doubt that the position of new energy vehicles in my country's automobile market will become increasingly stable.

Due to the advantage of “no endurance anxiety”, currently, plug-in hybrid technology and extended-range hybrid technology have become popular types of new energy vehicles chosen by consumers. Because of this, the debate about the “better and worse” of the two technical routes, plug-in hybrid and extended-range hybrid, has never stopped.

##Every new energy user, I believe, has also had entanglements and research when facing the above different new energy technology route choices.

Insert hybrid or extended range, in fact, this is not a judgment question, but a "mixed multiple choice question".

Here, I can briefly give you some popular science

What is plug-in? What is range extension?

The engines of traditional fuel vehicles and current hybrid vehicles can be directly driven. The so-called plug-in hybrid combines the advantages of pure electric vehicles and traditional fuel vehicles. The engine can participate in power generation (series connection) and the motor drives the vehicle. It can also participate in direct drive (parallel connection) and drive alone or together with the motor. Vehicle

In short, a range-extended vehicle is a vehicle driven by pure electricity, which can be charged externally and has a built-in engine. This engine can only be used to generate electricity and cannot directly drive the car

Regardless of other technical aspects, the extended-range hybrid is simpler in technical structure, while the plug-in hybrid structure is more complex. After all, the plug-in hybrid The engine can also participate in direct drive and has two power systems, while the extended-range version only has one power system.

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

The original sentence does not need to appear, the rewritten content is: in In extended-range hybrid models, the engine does not directly participate in driving, and there are only two working modes: pure electric (EV) and series hybrid

The rewritten content is: The engine of a plug-in hybrid vehicle can be directly used For driving the car, there is no need for energy conversion. Plug-in hybrid vehicles can maintain high efficiency and low fuel consumption under various road conditions, including urban roads and highways. On fast roads and high-speed modes, the fuel economy of plug-in hybrid vehicles is higher than that of extended-range hybrid vehicles. In high-speed road conditions, extended-range hybrid vehicles need to continue to burn fuel through the engine. The oil provides power, which is then passed to the motor to drive the car. This process has gone through an energy conversion, which is not as efficient as engine direct drive. Compared with "plug-in hybrid", the fuel economy is slightly inferior.

Therefore, what consumers can most intuitively feel at the experience level is that under urban road conditions, the difference in fuel consumption of these vehicles is not too big. However, during continuous highway driving, extended-range hybrid vehicles often suffer from higher fuel consumption due to battery 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. The extended-range hybrid can be said to be a "simplified version" of the plug-in hybrid. The plug-in hybrid is the optimal solution that takes into account urban experience and high-speed fuel consumption.

Plug-in hybrid, the technical threshold is higher

Some new power brands will also choose extended-range hybrid technology in addition to the pure electric line. In essence, the range-extended hybrid is equivalent to a pure electric range extender. Plug-in hybrids require hybrid-specific engines and a series of complex technologies such as electric hybrid systems. Therefore, relatively speaking, plug-in hybrids have higher technical requirements and the entry threshold will of course be higher.

This point was explained in detail at the previous expert media exchange meeting of the China Electric Vehicles 100 Forum (2023) by Ouyang Minggao, an academician of the Chinese Academy of Sciences, a professor at Tsinghua University, and the vice chairman of the China Electric Vehicles 100. , "You have to say that the technical threshold is definitely higher for plug-in hybrids, so generally new car manufacturers will not choose plug-in hybrids."

In terms of the choice of technical routes, most car brands that have accumulated technology Choosing the plug-in hybrid route, plug-in hybrid technology is gradually taking a dominant position in the new energy vehicle market. The most representative one is BYD, whose DM-i super hybrid technology has become a household name. The rapid growth of plug-in hybrid vehicles is largely due to BYD. As the leader of plug-in hybrid vehicles, BYD's DM-i model sales reached 123,000 units in June this year, accounting for nearly 60% of the entire plug-in hybrid market. In the past October, BYD sold a total of 135,590 DM models, a year-on-year increase of 18.6%.

BYD's DM-i super hybrid system is inseparable from one of its core components - the engine specially built for DM-i super hybrid technology. This engine once set a record as the world's most thermally efficient mass-produced gasoline engine with a thermal efficiency of up to 43%

For automobile manufacturers, extended-range hybrid technology is a low-barrier, low-cost technology with obvious cost advantages. However, in fact, many extended-range hybrid models are priced higher than comparable plug-in hybrid models. This is because of publicity and publicity, but actually because of the deficiencies in cost control of relevant car companies

For ordinary consumers, plug-in hybrid or extended range is not a question of right or wrong. After all, each specific product has its own advantages and applicable scenarios, as well as comprehensive competitiveness, including safety, comfort, technological configuration and other comprehensive strengths.

In any case, the current new energy market is developing very rapidly. In just ten years, China's automobile market has undergone earth-shaking changes. In the days when joint venture brands were at their peak, consumers had no choice when it came to automobile products. But now, they are "unable to choose." So why not? Isn't that a huge improvement?
