When it comes to pure electric vehicles, many people are concerned about how large is its battery capacity? How efficient is the charging efficiency? Of course, the most critical aspect is the security aspect. In fact, at the end of the day, these are all linked to technology. Regarding the technical level of pure electric vehicles, many people tend to overlook the important point, that is, the exclusive platform for pure electric vehicles, or architecture. In other words, if a pure electric vehicle is not derived from a pure electric exclusive platform, it will be called "oil to electricity".
The so-called "oil to electricity", the simple understanding is to add motors and batteries on the basis of the original fuel vehicles, and cancel the engine. For example, the recently popular BMW new i3, some people say that it is the "oil to electricity" version of the 3 series. There are two reasons, the i3 and 3 series look too similar, and in addition, BMW has not had a pure electric exclusive platform so far. Including i3, iX, i7 are derived from the CLAR platform, and the platform can build both fuel vehicles, hybrid and pure trams. Therefore, based on the second point of view, it is not unreasonable to say that i3 is "oil to electricity". But according to this logic, is the BMW i7 also the "oil to electricity" version of the 7 Series?
It will not be after 2025 that BMW will launch an exclusive platform for pure electricity
In fact, the so-called pure electric exclusive platform, BMW also gave a clear explanation. First of all, the CLAR platform itself is not only for pure fuel vehicles, but a comprehensive elastic platform that can take into account the manufacture of fuel vehicles and new energy vehicles. According to BMW officials, before 2025, new energy vehicles will be built in the form of such a non-exclusive platform.
Having said all this, it can be concluded that the i3 is indeed not from a pure electric exclusive platform, but it is not completely correct to say that it is "oil to electricity". Because first of all, we have to know, what are the drawbacks of the "oil to electricity" model? It is easy to understand that the body construction of a car, the core part is designed for fuel vehicles, such as the engine compartment is to put the engine, the rest of the position also has its use, in other words, if you want to put down the motor, especially the dual motor, as well as large-capacity batteries and other electronic control components, there is almost no suitable position.
If it is forcibly changed, it can only "steal space", so that the crew compartment space will be directly affected, including saying that the shape of the car will look abrupt. The most important point is that after this change, it is not possible to maximize the efficiency of a pure electric vehicle, including the maximization of safety.
Why is the i3 not a simple "oil to electricity"?
But for the i3, as far as the information we have is concerned, there is no "abrupt" problem with this car. First of all, in terms of appearance, the body shape of the i3 is very natural, for example, even if it is equipped with a large-capacity battery of 70kWh, you can not see the battery pack under the car.
In addition, as a pure electric vehicle with a rear-wheel drive, a single motor with a maximum power of 210 kW is placed directly on the rear axle. You know, if you only add the rear motor on the basis of the fuel vehicle, it is difficult to put down the motor in space, and the motor is placed in the engine compartment and the form of the rear drive is realized through the drive shaft, and the effect is another matter.
Again, through the experience of the space of the i3 car, you will find that it is not much different from the 3 series. Therefore, regardless of technology, with what you see and experience, you can prove that i3 is by no means a simple "oil to electricity".
Ah Chuan commented on the car
Many friends may also overlook the point that the i3 is equipped with air suspension on the rear axle on the basis of the 3 series, and the front and rear axles are equipped with HRS hydraulic rebound damping to improve comfort; in addition, compared with the 3 series, the rear axle of the i3 is also equipped with anti-roll bars. From another point of view, the transformation from "oil" to "electricity" is the foundation, and on this basis, more equipment can be added to improve comfort and movement. Such a calm "oil to electricity", will you refuse? Therefore, I personally believe that we cannot be paranoid about looking at problems, and good and bad are not absolute, but a kind of balance.
