Oil car or tram?Once upon a time, this was the soul torture that many people had to make before buying a car. With the further popularization of new energy vehicles and surrounding facilities, trams have become unstoppable. However, when choosing an electric car, many consumers still have anxiety about electricity, but oil and electricity have become darlings, and today's soul torture has become a choice between plug-in hybrid and extended-range electric.
In fact, this hot issue has been discussed in many forums or roundtable discussions at automotive events, and there have been many industry leaders or professionals who have collided with each other. For example, during the China Electric Vehicle 100 Forum (2023) held on February 17, 2023, Ouyang Minggao, an academician of the Chinese Academy of Sciences and an expert in new energy power systems and transportation electrification, gave an in-depth interpretation, which is worth referencing.
First of all, from a technical point of view, Ouyang Minggao said that the current plug-in hybrid and extended-range electric are essentially "the same system", "when there is electricity, both are pure electric vehicles", and when they enter the state of power loss, they are not the same. In the past, the pure electric mileage of plug-in hybrid was relatively short, but now it has reached more than 100 kilometers, such as BYD super hybrid.
The range-extender electric power loss is switched to a series hybrid mode of operation, and the engine is used to generate electricity instead of directly driving the wheels. Plug-in hybrids have many operating modes that can be connected in series or parallel, "the engine can not only generate electricity, but also drive the vehicle together with the electric motor (parallel), or even drive the vehicle separately." However, the threshold of plug-in hybrid technology is higher, and a series of new technologies such as hybrid engines and exhaust gas boosting are required, so new forces will not choose plug-in hybrids.
At the level of use scenarios, Ouyang Minggao pointed out that when the vehicle runs in the urban area and loses electricity, the economy of series connection is good. That is to say, if it is mainly used in urban areas, there is no difference in the economy of range extender and plug-in hybrid. In the highway long-distance running, plug-in hybrid is likely to be parallel or engine direct drive, the vehicle fuel consumption can be less than 100 kilometers 4 liters, compared with the high fuel consumption of high-speed driving power loss of range extender, plug-in hybrid economy is more advantageous.
Ouyang Minggao believes that both plug-in hybrid and extended-range electric are competitive and serve different customer groups. If the vehicle does not run many long distances every day, it is not a problem for the extended-range electric to occasionally have high fuel consumption, and many consumers in the market welcome it. If you mainly run high-speed and long-distance distances, or need to run often in urban areas, and run high-speed, based on cost considerations, hybrid plugging can take into account the dual needs of vehicle performance and economy, which is of course very good.
When it comes to plug-in hybrid technology, BYD's super hybrid DM-i is widely recognized both inside and outside the industry. In the industry, the super hybrid DM-i has broken through the technical threshold of high cost and difficulty of traditional plug-in hybrid solutions, combined with its own strong integration capabilities, achieved better cost control through rapid iteration, and continued to lead the rapid evolution of plug-in hybrid routes, including Geely, Great Wall, Chery and other major manufacturers are following up.
Outside the industry, a number of BYD's models based on the super hybrid DM-i have become popular models, and consumers' good word of mouth has been spreading, forming a positive virtuous circle, and continuing to promote the sales of all BYD models. Taking the Qin PLUS DM-i 2023 Champion Edition as an example, the sales volume has continued to lead since its launch, and the Qin family has achieved 9 consecutive monthly sales of family sedans. The blessing of DM-i can do 3With a subversive fuel consumption of 8 liters and 100 kilometers, the vehicle has five characteristics: fast, economical, quiet, smooth and green.
According to the latest released data, BYD's passenger car sales in November 2023 were 301378 units, a year-on-year increase of 311%, and the cumulative sales volume this year has reached 26720,000 units, and the company is expected to reach a new milestone of 3 million units in sales for the whole year.
Keke Comments: In essence, plug-in hybrid and extended-range electric belong to a unified system, extended-range electric high-speed fuel consumption is larger, plug-in hybrid can take into account the dual needs of vehicle performance and economy, and match a wider range of groups. Consumers can choose according to the actual use of the car.
