Currently talking about hybrid cars, the market is distributed in a variety of forms, which also has a variety of classification methods, what a strong mix, weak mix, parallel type, tandem type, etc., made people confused To be honest, the more full of articles in this academic range, the more they read and dizzy. Of course, those classification methods are more meticulous, or the thousands of words may only say a few of them. Naturally, people are puzzled.

Of course, there are also such simple and crude classification methods, which are divided according to the configuration existing in the hybrid system, but are still similar to the strong and weak mixed, and are not comprehensive enough. Nowadays, we have learned the profound things in a simple way. We use the method of summing up the vehicles and summarizing them. If there are any inaccuracies, we welcome communication in the commentary area.

Extender mixing

Why did you put a picture of the BMW i3? The car gods surely knew it all, and it also had a mixed version (extended range). This is actually not really mixed, because its structure is extremely simple. The gasoline engine is used to charge the battery. It does not directly participate in the driving of the vehicle, but the electric motor is the same as the pure electric version. Its gasoline engine is a 0.647L EFI naturally aspirated engine, but also to add 95 gasoline! How can you afford to pay more than half a million if you don't add 95?

However, not to mention the price does not say that if this system is based on the level of micro-mix, and the cost is relatively low, in fact, is still quite suitable for national conditions, after all, the coffee rule is too sudden, there is no time to study advanced hybrid technology Well !

Single motor direct connection

The most familiar model of this type of hybrid is the A3 e-tron. As a plug-in hybrid model, the entire e-tron has also entered China earlier. It can be called a hybrid at this level, or it can be understood as a primary hybrid because its mixing efficiency is not very high.

This picture should be the most simple and easy to understand figure, the red part is its core - a motor, watching it very deep? In fact, it is to separate the hydraulic torque converter of the transmission from the planetary gear on the rear end, and add a motor in the middle. However, in the actual process, this motor has several positions, both as a generator and an electric motor, and these two tasks cannot be performed at the same time. Therefore, the efficiency of the motor and the following several mixed modes that I have to say are much worse.

However, the three BBA players are enjoying themselves. Even the S-class has gotten this "mixed". According to Che Junjun, because European environmental protection laws are not fuel-efficient lights, and high-efficiency hybrid systems have patent protection, it is the best way to meet the current policy. The best way to identify it is to tell you that the car is also secretly telling you that this car only needs to look at the form of gearboxes on the configuration list. All those 6-speed manuals and 7-speed dual clutches will explain it. It is this simple light mixing.

Double motor direct connection

Speaking of this form of mixing, it can only be said that the industry's boss Toyota's THS hybrid system expires this year. The system currently on sale in the market is the second generation. Its structure is very complicated, but thanks to its earlier and very good reputation and stability, it can make it possible to use a car like Corolla and Ralink in a " Cabbage price" met with us. Needless to say, dual motor, one is a part-time generator and motor, one is a pure motor. It does not have to say more about its fuel economy. Small partners can refer to the measured data of major institutions. Of course, its high-end brand, Lexus, is, to a certain extent, the same principle as it is, and it will be more complex and efficient, and we will say it later.

The advantage of this PS (power split power split) mode is that it does not require a transmission in the traditional sense to achieve different gear ratios. The essence of the entire structure is the planetary gear set. Through the different locking modes and the number of locks between the ring gear, planet carrier, planet gear and sun gear, different transmission effects and seamless power switching can be achieved. The real complexity is its PCU (power control unit). Whenever, with whom's motivation, how to use is the most troublesome problem for engineers. Fortunately, the maturity of this technology has developed into how you can solve the problem when you are in the car. It will not give you a trace of setback!

Lexus's high-end vertical model (LS) goes further on the THS system, adding a 4AT gearbox to the rear, and the system is 2AT on the GX's hybrid car. The front structure is the same. Why? In fact, it is well understood because its engine is a V6 of 3.5. If such a powerful engine does not add a variable tooth ratio, it will reduce energy and efficiency and it will not be able to achieve its maximum level. Of course, in the process of opening, it is still not possible to feel frustrated, and only the sound of the engine will be somewhat like the fluctuation of the traditional transmission models.

Double motor non-straight mixing

Just talking about direct-connected Toyota, let's talk about non-direct Honda, in fact, its structure is simpler and more fuel-efficient. There is no planetary gear structure to determine who is responsible for who will be charging. Instead, a simpler solution is to put the battery between the No. 1 motor and the No. 2 motor. The No. 2 motor drives the wheels. The No. 1 motor is only used to give Charging batteries. Simply put, Toyota's engine, battery, and two motors are nearly parallel, so it takes planetary gears to allocate power to work, and because of the direct connection, there is still a limitation in efficiency. (Although already high).

Honda's method is connected in series. The battery is a special storage tank for storing energy. Most of the time, the wheels are driven by the No. 2 motor. Of course, this is not finished yet. When you need power, Toyota can use a parallel structure to make the engine and the motor work together. How does Honda do it? The answer is the PTO (power take off) device and a set of clutches. The common understanding is that the engine power take-off device is directly connected from the engine to a driveshaft and after the clutch is engaged. This directly drives. To be honest, it's not advisable to admire these engineers!

Worthy of recognition of Roewe plug-in hybrid

I have to say that I have only found Roewe in my own brand. I have found Roewe. Its design is similar to that of Honda's. It is also a dual-motor non-straight hybrid structure. However, it has The No. 1 motor can also drive wheels, which is similar to Toyota's, but it does not involve complicated planetary gears. Instead, two sets of clutches are added to the front of the two motors. The second feature is the addition of a 2AT transmission before the transmission of power to the wheels, which further increases the efficiency, which is the same as that of the Lexus series AT. Therefore, the measured fuel consumption is also very impressive. With durability first put aside, this patentable system is a big step forward for its own brand.
