original title: new energy vehicle parts should not blindly pursue large
the latest data from the china association of automobile manufacturers shows that in the first eight months of this year, the production and sales of new energy vehicles in my country both exceeded 7 million, up about 30% year-on-year, and the sales of new energy vehicles accounted for 37.5% of the total sales of new vehicles. among them, the production and sales growth rates of plug-in hybrid vehicles were as high as 79.3% and 84.2% respectively, becoming an important force driving the overall growth of new energy vehicles. however, in the process of rapid development of the industry, there has been a phenomenon of blindly pursuing large products, which should be vigilant.
big battery. many car companies now launch pure electric models, which often claim to have a range of over 700 kilometers, over 800 kilometers, or even over 1,000 kilometers. how necessary is this? it is worth discussing. if it were not for the increase in battery energy density due to technological progress, simply installing more batteries to achieve a high range would not only increase the vehicle's own weight, but also increase energy consumption, which goes against the original intention of the industry's development. moreover, installing more batteries will also increase the cost of vehicle production. it would be better to save this part of the cost and benefit consumers, which may better promote the increase in sales of related models.
it should be noted that with the increase in the number of new energy vehicles, under the guidance of national policies and the investment of social capital, my country's charging and swapping infrastructure is becoming more and more perfect. compared with the period of new energy vehicle promotion, the current consumer's "driving range" anxiety has long turned into a worry about "inconvenience of recharging". therefore, car companies do not need to rely on blindly stacking batteries to increase driving range, but should focus on the high-quality improvement of the vehicle's technical level. after all, before the revolutionary breakthrough of power battery technology, this "carrying heavy load" will not only bring greater cost burden to car companies, but also directly affect consumers' purchasing and driving experience.
big fuel tank. due to the fact that they can be powered by oil or electricity, coupled with the no-traffic restrictions and purchase tax preferential policies in some cities, plug-in hybrid vehicles, including extended-range vehicles, have been popular among consumers in recent years, and their sales growth rate has far exceeded that of pure electric vehicles. the problem is that these cars, which claim to have a "comprehensive driving range" of over 2,000 kilometers, rely not on small batteries but on big fuel tanks. in may this year, after a certain car company launched a new product, an industry insider questioned, "they call for a ban on fuel vehicles every day, but they built a plug-in car with a bigger fuel tank than a fuel car."
in analysis, it is meaningless for plug-in hybrid vehicles, including extended-range electric vehicles, to blindly pursue "comprehensive driving mileage", especially by increasing the fuel tank capacity. at present, there are more than 120,000 gas stations across the country, and the maximum interval between gas stations is only about 350 kilometers; the interval between gas stations on general roads and highways is no more than 60 to 70 kilometers, and there will be multiple gas stations within 100 kilometers on roads with heavy traffic. the reason why traditional fuel vehicles do not blindly pursue the phenomenon of driving mileage is largely because there are gas stations everywhere.
although a large-volume fuel tank has little impact on vehicle manufacturing costs, plug-in hybrid vehicles, including extended-range vehicles, still rely more on fuel to drive over long distances, which is not in line with the concept of green environmental protection. the reason why the management department classifies plug-in hybrid vehicles, including extended-range vehicles, as new energy vehicles and excludes deep oil-electric hybrid vehicles is to encourage more electricity, more green electricity, and less fuel. if the only ordinary passenger car that needs an ultra-long driving range is an off-road vehicle, it is likely that it is a mainstream family sedan, suv, and mpv. there is really no need to use a large fuel tank.
big screen. i don't know when it started, but the big screen trend has swept the automotive industry. domestic cars, joint venture cars and even luxury cars all have big screens in their cars. some models are so exaggerated that the entire dashboard has become a huge screen. they look cool, full of technology and fashion, but is it really good to do so?
big does not mean good. "digitalization is not about who has the biggest screen or the longest code... many car companies now offer large screens, which may distract drivers and cause accidents." bmw group chairman zipse bluntly pointed out that consumers should pay attention to vehicle performance and safety configuration when choosing a car, rather than just pursuing superficial configurations such as large screens, large color tvs, and large sofas. it is even suspected that those so-called "big" cars are actually using "piling up materials" to cover up their lack of innovation.
at present, with the accelerated evolution of a new round of scientific and technological revolution and industrial transformation, the wave of electrification and intelligent transformation is surging, but this does not mean that car companies should blindly pursue size in product design and development. at any time, the first attribute of a car is still a means of transportation. whether it is easy to drive, whether it is fun to drive and has good ride quality, whether it is safe, reliable, green and intelligent enough, are the anchor points that car companies need to innovate, and new energy vehicles are no exception.
