in just a few years, range-extended vehicles have transformed from "everyone clamoring for them" and "backward technology" in china to "the most advanced technology" and a best-selling model.

in terms of sales, the sales volume of extended-range electric vehicles in the first half of this year reached 469,000, a year-on-year increase of 124.2%, far exceeding that of plug-in hybrids and pure electric vehicles.

judging from public opinion, cui dongshu, the former secretary-general of the passenger car association, affirmed the development prospects of extended-range electric vehicles. he made it clear that extended-range electric vehicles essentially belong to the category of electric vehicles.

later, yang yusheng, an academician of the chinese academy of engineering, strongly supported and was optimistic about the extended-range electric technology at the 2024 china (zhengzhou) new energy vehicle ecological partner conference: "the extended-range electric technology is the most advanced, integrating excellent technologies, energy saving and emission reduction, and has great application prospects. unlimited".

he also said that extended range is the ultimate form of pure electric hybrid, and it is recommended that extended range models be given the same treatment as pure electric vehicles.

recalling the statement made by li xiang, the founder of ideal, a few years ago, the end of intercourse is extended range. now it seems that more and more people in the industry are beginning to agree with this view.

however, if the range-extended technology is so good, why do overseas car companies rarely adopt and vigorously promote range-extended electric vehicles? i can share with you the opinions of several of my friends who work and study overseas.

let’s first talk about why extended range is so popular in the country.

range-extended vehicles do not have traditional structures such as gearboxes and are simple in structure. therefore, the cost threshold is lower whether from the perspective of the r&d design of the car company or the subsequent maintenance of the user;

the range extender only generates electricity and does not participate in direct drive most of the time. compared with plug-in hybrid vehicles, range extenders can use larger batteries, so the inductive experience is better than that of plug-in hybrids, and the acceleration performance can be infinitely close to that of pure hybrid vehicles. electricity;

precisely because the electronic control system of a range-extended vehicle is most similar to a pure electric vehicle, it is generally believed that it will be easier to implement more intelligent functions, such as intelligent driving, on a range-extended vehicle than a plug-in hybrid vehicle.

these are the three most prominent product advantages of range extenders.

in addition, a major premise that cannot be ignored is our country’s national conditions. our country has world-leading infrastructure, a sound charging network, and abundant and cheap power resources. at the same time, our country has a vast territory, spanning 5 climate zones, and the travel scenarios are more complex. there is also the world's largest "population migration activity" every year.

these two conditions lead to the fact that we not only want to profit from the tram, but also do not want to be subject to various restrictions on travel at critical moments. therefore, the extended range of oil and electricity can be used to meet both needs.

but no matter how popular the chinese think extended-range hybrid technology is, it cannot change the attitudes of europe, the united states and japan towards extended-range hybrid technology.

first of all, although there is currently a tendency in our country to "rectify chaos" with extended-range technology. but objectively speaking, range extension is not a new technology.

in fact, porsche launched a range-extended car in 1901, and bmw's old i3 also used a range-extended vehicle. however, the market performance of these models ultimately failed.

this also led to overseas car companies ultimately not choosing to continue exploring the technical route of range extension. the extended-range model has not formed an industrial atmosphere overseas. to develop this route requires continuous investment of considerable resources and time, which is obviously not cost-effective for overseas car companies.

secondly, the environmental protection requirements of europe and the united states are different from those of my country. in europe and japan, the main consideration for vehicle environmental protection is energy consumption, while in my country, the main consideration is emissions. if the extended-range engine is simply refueled, it will not be fuel-efficient in terms of displacement and use, and it has no advantage over european and japanese engines in terms of energy efficiency. (of course, domestic brands have gradually narrowed the gap through efforts in recent years.)

therefore, in many countries in europe and the united states, vehicles with extended range and plug-in hybrids that can also use oil are excluded from the future series of environmentally friendly vehicles. some people even think that range extension is a "lazy" design for environmental protection, which has led to the stagnation of electrification to a certain extent. therefore, range extension also lacks policy support abroad.

the third point is that based on national conditions, the european and american markets are unlikely to be that interested in range extension.

in developed countries in europe, the united states and japan, most people are actually not sensitive to fuel consumption, because fuel costs have a very small impact on their income. on the contrary, their electricity prices are very high, even several times higher than in china. it burns oil, but can't use electricity, so if it weren't for the big concept of environmental protection, many foreigners might not be that interested in trams.

there are only a few charging piles, and the price of charging is almost as high as refueling - will everyone still favor this model? definitely not!

in addition, the european and american automobile markets have developed for a hundred years and have formed a relatively fixed automobile culture. at least when it comes to cars, the proportion of european, american and japanese car enthusiasts who are "nostalgic" is much higher than ours.

not long ago, in the final chapter of the well-known overseas car program "tgt", when the host talked about the reason for the end of the program, he did not forget to complain about electric vehicles, thinking that electric vehicles are just household appliances and garbage. this actually represents the attitude of many european and american users.

this is also the reason why extended-range vehicles are very popular in china but not abroad.

after all, under china's special national conditions, zengcheng has fertile soil to nourish and thrive. as a result, there are arguments that the extended range is more advanced, and that the extended range is a pure electric car with a generator added, which is contrary to tiangang.

if the extended range is placed overseas, there will not be such a good development environment, and it will not be as easy to sell as ordinary oil hybrids.
