Most traditional car companies think that the technology of adding programs is useless and their own technology is much advanced, but from an ideal point of view, adding programs is much more advanced than traditional car companies. Even many media believe that the extended program belongs to pure electricity, and it is a racer on the same track as Weimar Weilai in Tucki, which has a crushing advantage compared with plug-in hybrid cars.
But today we are going to tell you what an extension program is.
Is this pure electricity or mixed electricity?
First of all, we must clarify a technical fact: the extended program is not pure electricity, but belongs to the category of plug-in hybrid. From the technical route, it belongs to the very early first generation plug-in hybrid. To explain this, we should start from around 2003-2005. At that time, Toyota's THS hybrid car was born, which opened up a new battlefield for hybrid cars. This shocked all the car companies in the world at that time.
Everyone wants to imitate Toyota's THS hybrid, but Toyota's THS hybrid has arranged many patents in every detail, and other car manufacturers have no way at all. In order to compete with Toyota, other car companies have begun to use a relatively simple hybrid technology: series hybrid. As the name implies, series hybrid power is to connect the engine and motor in series, and then output power to the transmission system through the gearbox. Simply put, a motor is connected in series behind the flywheel of the engine. This is the original hybrid prototype.
However, this prototype has many problems. Later, after continuous improvement by Japanese companies headed by Honda and Nissan, the series of hybrids finally matured. Honda calls this technology i-MMD and Nissan calls it e-Drive. At the same time, BMW, which happened to have technical cooperation with Honda, also acquired this technology, which was improved again and named as extended-range hybrid.
Later, with the continuous development of plug-in hybrid technology, three more advanced hybrid forms such as parallel hybrid, power split hybrid (Toyota THS belongs to power split, and other car companies bypass Toyota patents) and series-parallel hybrid have been eliminated by car companies one after another. Even Honda and Nissan now use series-parallel hybrid power.
Why does series mixing suddenly become pure electricity?
So to put it bluntly, Li ONE's seemingly advanced hybrid system is actually quite backward in technical architecture, not a pure electric vehicle. Then why does Li install pure electricity at home alone? This is actually a bad news, playing word games.
China does not strictly stipulate what a "pure electric vehicle" should look like. As long as your car can be driven by pure electricity, theoretically you are pure electricity. In this way, all plug-in hybrid cars on the market are theoretically pure electricity. However, for traditional car companies with strong engineers' thinking, pure electric vehicles mean that this car can only be driven by motors, that is, cars like Weimar Weilai are now pure electric, and as long as there is an internal combustion engine to participate in the drive, they are all mixed.
But it is ideal to think that because their Li ONE has the function of pure electric drive, it is really pure electricity in theory, and because pure electricity is the hot spot and the general trend now, it is used as the entrance of publicity. This is the different attitudes and practices of Internet-based enterprises and traditional enterprises to look at the same thing.
Core question: Is the program behind?
This is another word game. There is no unified technical concept for extended-range vehicles, and it is not just series hybrid vehicles that are considered to be extended-range vehicles. Nissan's latest generation of series-parallel hybrid vehicle technology, also known as extended-range vehicle. The latest generation of Honda i-MMD hybrid vehicle is also called expansion plan in Europe.
Therefore, it is difficult to draw arbitrary conclusions, and adding procedures will definitely not work. Even the most primitive series hybrid, that is, the ONE in Li One, can achieve very good fuel-saving effect if the system is optimized and adjusted well, just like the extended program technology of BMW I series.
Therefore, we can't answer "Is extended range mixing a failed technology?" Because there is no solution to this problem. But what we can answer is this question: Can a well-adjusted series hybrid technology compete with more advanced hybrid systems? "The answer is right, but the problem is that there is only one BMW in the world, and there is no semicolon.
