In recent years, the development speed of new energy technology can be said to have surpassed almost everyone's imagination. According to relevant data, in 2023, the penetration rate of new energy vehicles in China will reach 316%, the sales volume of new energy vehicles has reached nearly 10 million, even if the relevant subsidies are declining year by year, it still has not resisted the enthusiasm of the market.
As one of the major categories of new energy vehicles, the market growth rate of hybrid models is even more amazing, and there has even been a year-on-year increase of 89%.2% of the data shows the degree of consumer recognition of it. Today's three mainstream hybrid technologies, traditional range extender, single-speed hybrid, and multi-gear hybrid, have different emphases and characteristics. Next, let's break them down one by one.
When it comes to traditional range extender technology, many people will think of the ideal in the "New Power Royal Three". In that era when the range extender was complained of as "backward technology", Ideal relied on the traditional range extender technology to launch a number of popular products, becoming the first car company in "Wei Xiaoli" to achieve profitability. Compared with single-gear and multi-gear hybrid technology, the biggest advantage of traditional range extender technology is that the technical threshold is low enough, so that new power car companies with relatively weak technology accumulation can also quickly launch products and occupy the market.
At the same time, the traditional range extender technology adopts series hybrid, abandoning the path of direct engine drive, and can bring a "inductive" driving quality when the power is sufficient. "It not only ensures the driving quality, but also does not have too high technical difficulty." Traditional range extender technology sounds like a good idea, so why are car companies developing new hybrid technologies? The reason is that the traditional range extender technology is limited by the structural characteristics, when the vehicle battery is in an extreme feeding state, the power will be limited by the power of the generator, at this time, if it accelerates sharply, not only the range extender will increase the noise at high speed, but also there will be a problem of insufficient power. At the same time, the power transmission of traditional range extender technology needs to pass through the path of "range extender - generator - drive motor - wheel", which will also cause a large loss of efficiency and increase consumption.
Compared with the "simplicity" of traditional range extender technology, single-multi-gear hybrid is obviously more technically difficult in terms of research and development, but the benefits are also obvious. Taking BYD's DM-i technology as an example, as a "leader" in single-speed hybrid technology, models using DM-i technology can minimize fuel consumption under the premise of only one high-speed gear, so as to achieve the purpose of saving money. At the same time, compared with the traditional range extender that cannot be directly driven, the high-speed energy consumption performance of the single-speed hybrid has also been optimized, but it is limited by only one gear, which is bound to sacrifice the power performance in high-speed working conditions.
At this time, the emergence of multi-gear hybrid technology can be regarded as the completion of the "integration" of the above two technical advantages.
Take the Lynk & Co EM-P super extended range electric solution based on multi-gear hybrid as an example, which emphasizes electric drive and pays attention to the performance of inductance, driving control and range. With the support of this technology, the CLTC engineering pure electric range of its models can exceed 120km, the comprehensive cruising range of more than 1200km, and even models such as the Lynk & Co 08 EM-P, with a pure electric range of 245km (CLTC working conditions), which is better than most single-speed hybrid models on the market.
In terms of high-speed performance, the "pain point" of traditional range-extender single-speed hybrids, the Lynk & Co EM-P super extended-range electric solution retains the direct drive of the engine, which can ensure continuous power output. What's more, the vehicle can be adjusted in three gears according to the existing working conditions and the driver's power needs, and the forward can be downshifted to increase torque, and the reverse can be upshifted to reduce the speed to achieve better energy consumption. Even, in the off-road scenario, the electric hybrid engine adopts a 1-speed large speed ratio, and the low-speed state can be intervened to drive, and the torque generated is quite amazing, truly realizing high-speed and non-soft, long-distance and off-road without panic.
It can be seen that the Lynk & Co EM-P super extended range electric solution based on multi-gear hybrid is more like a "master" that combines the advantages of traditional range extender technology and single-speed hybrid technology, and at the same time improves the "stubborn problems" of these two technologies. Presumably, it will also become the mainstream of the new energy market in the future and become the future development direction.
