Although both Toyota and Honda have hybrid electric systems, their hybrid systems are very different.
Toyota THS hybrid power started relatively early, which can be said to be the most mature hybrid power system in the world. Today, Toyota's global sales of hybrid models still exceed10 million, which has withstood the test all over the world and is particularly durable. Someone abroad specially tested a Prius that ran for 300,000 kilometers, and found that the power of the Prius did not decrease after running for 300,000 kilometers, and the power parameters were still close to those of the new car. This is why Toyota Hybrid is the most mature hybrid. Toyota's hybrid system is very smart, using a set of planetary gear sets to perfectly combine two motors with the engine.
The outer gear ring is connected with the motor 2 and the wheel through a reduction mechanism. The planet wheels are installed on the planet carrier, which is connected with the engine. The blue sun gear in the middle is connected to the motor 1. These three elements are inseparable. As long as the rotational speed of one component changes, the rotational speeds of the other two components will also change. In this way, the seamless connection between the engine and the motor can be realized, and the speed ratio can be changed at will to keep the engine running in a high efficiency range. The Atkinson cycle engine with high utilization rate and thermal efficiency as high as 42%, Toyota's THS hybrid fuel consumption is very low, and the fuel consumption of Corolla/Ralink dual engine Ministry of Industry and Information Technology is 4. 1L/ 100km. In addition to low fuel consumption, seamless power connection and invincible ride comfort.
The biggest feature of this system is low energy consumption, and the whole system has been making a fuss about energy consumption.
But there is no perfect hybrid power system, and THS system has the disadvantage of weak power. Moreover, the motor and the engine cannot be decoupled, and there is always motor idling when working. When the motor drives the vehicle in the pure electric mode, in the engine driving mode, the generator rotates reversely (idling) and the motor rotates forward (idling). In pure electric mode, the speed of the generator is 2.6 times that of the motor, so it is not allowed for the generator to rotate too fast even if it is idling. What should I do? The engine exceeding 67 km/h must be started to stabilize the generator speed. Therefore, the double-engine speed-up only performed well in the first half, so this kind of car only emphasized the acceleration ability of 0-60km/h. After the speed exceeded 60 km/h, the engine intervened and the speed-up ability became weak. The same is true for high-speed driving. The motor is decoupled from the engine, so the performance of high-speed fuel consumption is not as good as that of low-speed and Honda hybrid.
Honda's oil-electric hybrid system started late.
After Toyota applied for the patent of planetary gear hybrid power system, later developers were wondering how to avoid Toyota's patent, while Honda did the opposite, just like its parallel shaft gearbox. Honda's ingenuity lies in that it only uses a clutch and a high-power motor to realize an IMMD hybrid system comparable to Toyota THS hybrid system.
This hybrid system looks more like a series hybrid.
However, the engine power can be superimposed with the motor, so the advantages of series connection are taken into account. When driving at medium and low speed, the engine only generates electricity at one side, providing power for the motor and storing excess energy in the battery. The whole vehicle is driven by a motor. Honda IMMD hybrid system is equipped with 135kw, 3 15Nm permanent magnet motors, which are enough to drive mid-level cars and have better power performance than engines. Because the motor is characterized by low speed and large torque, the motor torque will not change with the speed until it reaches the rated speed, and it is in a constant torque state. So the power of motor vehicles will be stronger.
When the vehicle speed increases and enters the cruise mode, the vehicle is directly driven by the engine. The engine directly drives the wheels through a set of reduction gears, which does not need power conversion and has the highest efficiency. At this time, the generator is still working, and the excess energy of the engine can be recovered to charge the battery. When the battery is fully charged, the vehicle is driven by the motor and the engine is turned off to save fuel consumption.
The motor and engine of IMMD hybrid power system can be decoupled, so the motor can drive the vehicle independently without speed limit. The power experience of IMMD hybrid system is stronger than Toyota's IMMD system, but at low speed in urban areas, the engine drives the generator, and the generator drives the motor, which leads to loss, so the fuel consumption performance at low speed is a little worse than Toyota's. However, at high speed, the motor and engine can be decoupled, and vehicles can travel alternately, so the fuel consumption will be slightly lower than that of Toyota.
The above are the advantages and disadvantages of the Japanese hybrid system. It can be seen that the two hybrid systems have their own emphasis, and they cannot directly judge who is good and who is bad. Toyota's ride comfort is its strength, and Honda's power performance is its strength. The comprehensive fuel consumption of the two systems is similar, but the fuel consumption is slightly different under different working conditions.
Let's take a look at the domestic boutique BYD hybrid.
BYD Hybrid is the plug-in hybrid system (PHEV) mentioned above. BYD's latest third-generation hybrid system adopts P0+P3+P4 architecture. Strictly speaking, this hybrid system is still a parallel hybrid.
The hybrid architecture is named after the position of the motor. BYD drive motor is installed on the output shaft of the gearbox, which directly drives the differential, which is connected in parallel with the gearbox. The advantages are strong power, which can directly increase the motor power, and the wheels can be superimposed in parallel with the engine power. So as long as the motor has enough power and torque, it can realize super-running acceleration. Therefore, it only takes 4.x seconds for BYD Tang DM to accelerate 100 kilometers.
Although parallel hybrid power is powerful and simple in structure, it also has many shortcomings. First of all, the motor not only drives the vehicle, but also recovers kinetic energy to generate electricity in situ, and the motor can only perform one task at a time, either driving or generating electricity. However, the motor behind the gearbox is not dominant in recovering electric energy, and the motor driven by the wheel-driven differential has a particularly low speed, which affects power generation. However, in-situ power generation requires engine power to reach the motor through the gearbox, which leads to large power attenuation, high working noise and low power generation efficiency.
In order to solve this problem, BYD improved it by installing a high-power BSG motor.
BSG motor replaced the original vehicle-mounted generator, and the power was also increased to 25kw. The BSG motor has the power generation/starting ability, but the power of the BSG motor is limited because it is connected with the engine through a belt. It can't completely replace the traditional starter for the time being, and the traditional starter is still needed during cold start. When the car is hot, BSG motor can be used to start and stop automatically, and the high-speed start is stable. After starting, the BSG motor can absorb the residual power of the engine, and when it is stationary, it can generate electricity. The efficiency of local power generation is much higher than that of the previous generation P3 engine, but the engine still has the problem of low power. Compared with Japanese hybrid, HEV mode has slow charging speed and low kinetic energy recovery efficiency. The working point of the engine is difficult to keep in the high efficiency range, and the thermal efficiency is obviously lower than that of the Japanese engine without Atkinson cycle engine. Therefore, in HEV hybrid mode, when the battery is exhausted, the fuel consumption is slightly higher than that of Japanese hybrid vehicles.
However, plug-in hybrid vehicles have one advantage, that is, they can reduce fuel consumption by increasing battery capacity and increasing cruising range.
If you commute 80 kilometers a day and have charging conditions, then plug-in hybrid vehicles can achieve zero fuel consumption and low cost. Therefore, plug-in hybrid cars are characterized by the strongest power and zero fuel consumption, but the fuel consumption after battery discharge is not as good as that of hybrid cars!
You can't have your cake and eat it.
Plug-in hybrid power is more suitable for commuting in urban areas, and occasionally runs long distances, with the highest cost performance. Hybrid electric vehicles have low fuel consumption, which can reduce the number of trips to gas stations, and the driving experience is obviously better than that of fuel vehicles. I'm used to the fuel car, so it's more convenient to use without charging. Plug-in hybrid BYD has the strongest power, lifetime battery warranty and high cost performance. Hybrid Toyota is the most stable, and the lifetime warranty of Ralink dual-engine battery is also the highest in its kind. Honda's hybrid is also the strongest among hybrid cars.
First of all, we have to figure out one thing, that is, cost performance. How to choose the most cost-effective hybrid car? We don't consider brand models, the most important thing is hybrid models. Common hybrid vehicles are divided into plug-in and non-plug-in, and friends who don't know think the difference lies in whether to charge.
In fact, there are many things to consider besides charging or not. The first licensing, plug-in hybrid cars can be environmentally friendly, non-plug-in hybrid cars can not. The second subsidy, plug-in hybrid cars can enjoy many benefits of new energy, and non-plug-in hybrid cars can't. Thirdly, the plug-in type can be opened for a certain distance in pure electric mode, and there is no need to plug in.
Hybrid or talk about Toyota's earliest popularization and implementation. The core component of TOYOTA THS hybrid system is a planetary gearbox named ECVT, which is matched with 2.5L Atkinson cycle internal combustion engine and motor. It is mainly driven by gasoline engine, but at the same time the motor occupies a relatively high proportion, which belongs to heavy hybrid technology. At the same time, THS battery pack is nickel-hydrogen battery, which is heavier than lithium battery, but its stability and reliability are very high.
Due to the special charge and discharge management, the battery life is very long when the discharge is only 40% and the charge is only 80%. Generally speaking, Camry hybrid is not only good in power, but also low in fuel consumption. In addition, hybrid technology has a high degree of popularity and strong reliability.
But the price/performance ratio, I have to mention the Ralink double engine or the Corolla double engine here. Why do you say these two cars? The reason is very simple, the market recognition is high, the product quality is good, and the fuel consumption is lower than that of traditional fuel vehicles.
In terms of appearance, it is close to the height of the fuel truck, and the power system adopts the same power combination, in which the maximum power of the engine is 73KW, the maximum power of the motor is 53KW, and the comprehensive fuel consumption of the Ministry of Industry and Information Technology is 4.2L per 100km.
With the development of new energy, pure electric vehicles can basically be said to be the future development trend. However, at present, pure electric vehicles are not mature enough in technology, and charging stations are not as popular as gas stations, so pure electric vehicles are still a little worse. It is difficult to choose between gasoline and pure electric, because both have their own advantages. If you want a middle value, then mixing is undoubtedly a better choice. Let's take a look at three famous hybrid systems in the world. Representative of general hybrid system: Regal HEV general hybrid leveling includes plug-in hybrid vehicles, non-plug-in hybrid vehicles and extended-range hybrid vehicles.
This hybrid system consists of a 1.8L naturally aspirated engine, two groups of permanent magnet synchronous motors, two rows of planetary gears and two clutches. The basic structure of the system looks complicated and feels heavy, but in fact, the weight of this power system is only 125KG, which is lighter than the products of the same level. In addition, it is worth mentioning that the transmission efficiency of double-star gear set is also higher than that of single-row gear set. This system has not only two pure electric modes, but also three modes: low speed hybrid mode, medium speed hybrid mode and high speed hybrid mode. The system can switch to different modes according to speed and load. Because of the clutch, there is no feeling of sitting in the process of mode switching. Honda hybrid system representative: Honda, one of the three giants in Japan, has a place in the hybrid field. Honda has three sets of hybrid systems, namely: i-DCD intelligent dual-clutch single-motor hybrid system, SH-AWD three-motor super four-wheel drive hybrid system and I-MMD dual-motor hybrid system. Among them, i-MMD system is relatively common at present, and Accord hybrid is the product of i-MMD system.
The system structure is not as complicated as Buick. It consists of Atkinson cycle engine, clutch, double motors and three shafts. Honda is the focus on electric drive, which greatly increases the power of the motor, so the Accord will not run out of power when starting and accelerating. In addition, when i-MMD system is working, it will constantly switch several kinds of power (EV mode, engine mode and hybrid mode), so the fuel consumption of the vehicle is low.
Toyota's THS-II hybrid system, the representative models of Toyota's hybrid system: Ralink twin-engine and Corolla twin-engine, are enough to make Toyota's hybrid field all-powerful. It is said that when Toyota developed this system, Honda i-MMD system took away Toyota's dominance, so it is necessary to develop a new system to stabilize its position.
This system is a power distribution system composed of planetary gears, which distributes power between the engine and two motors through clever logic. Like Toyota's i-MMD, they all use dual motors and Atkinson cycle engines. The motor mainly serves as an auxiliary engine. When the car starts, the wheels are basically driven by a mixture of engine and motor.
The above picture shows the power source comparison between Honda i-MMD and Toyota THS-II. As can be seen from the above figure, Toyota THS-II pursues the complementarity of motor and engine. At low speed or starting, the motor will give full play to its torque advantage and provide more direct torque. Cruise and high-speed driving, the engine plays a leading role and provides power. To sum up, the hybrid system technologies of these three companies are relatively mature and do well, so you can safely choose the above hybrid. Of course, there are other power systems to choose from, just for reference.
At the moment when battery technology is difficult to break through, hybrid car is a very good choice, because it has the convenience of fuel car and the advantages of electric car in driving experience and car cost, so how to choose the hybrid car in the market? Actually, the answer is simple. Fifteen words tell you how to choose a hybrid car, that is, "choose Honda for the hybrid car and BYD for the plug-in hybrid car".
Why did you choose Honda for oil-electric hybrid? At present, there are not many manufacturers who can play hybrid technology of oil and electricity in the market, only Toyota, Honda and Hyundai. Although some car companies have hybrid technology, they are actually licenses in two fields. Toyota is the originator of hybrid technology, so why not recommend Toyota when recommending hybrid cars?
Indeed, Toyota is the first car company to develop hybrid technology of oil and electricity. It is only promoted on a large scale, but its qualification does not represent everything. At present, Toyota's hybrid technology of oil and electricity lags behind Honda's hybrid technology in almost all aspects.
Compared with the structure, Toyota's hybrid technology is realized through planetary gear sets, which is complicated and expensive, while Honda's i-MMD is a dual-motor hybrid structure. Through the electrically coupled CVT technology, the system can be switched between series and parallel, and the structure is simpler, and the cost of the hybrid system itself is lower, so the Honda hybrid model can achieve a lower starting price.
Compared with fuel consumption, although both of them are top energy consumption levels, Honda's system gives full play to the efficiency advantage of the motor. According to the test of Japanese energy department, the 10th generation Accord equipped with the latest i-MMD hybrid has reached 30km/L, while the fuel efficiency of Toyota's THS II hybrid system is 23km/L, and Honda's hybrid is still slightly better.
Compared with the stability, the launch time of Honda hybrid is slightly shorter, and the first generation of i-MMD hybrid was launched abroad on 20 14. But so far, Honda Hybrid has not seen a large-scale quality scandal. The oil valve and gear door are both 1.5T versions, while Toyota Hybrid has recently seen an increase in engine oil and engine oil emulsifying phenomenon.
Comparing the driving experience, you can feel the obvious difference between the two when you test drive. Because Toyota's hybrid engine directly participates in driving the vehicle under the action of planetary gears, the torque will inevitably change at the moment when the engine begins to intervene. Although this change has been combed by Toyota's planetary gears, the driver can still detect it. Honda's hybrid is below 90km, and all engines are used as generators. At high speed, the engine directly drives the vehicle, which makes full use of the high efficiency range of the engine. The driving experience is the same as that of a pure electric vehicle at medium and low speeds, and the power is stepped on and the linearity is smooth.
It can also be seen from the comparison that Honda hybrid almost surpasses Toyota hybrid in all directions. The only drawback is that there is still a certain gap between low-temperature energy consumption and Toyota hybrid. So, if you choose a hybrid car, I strongly recommend that you choose a Honda hybrid.
Why did you choose BYD for plug-in hybrid? Compared with gasoline-electric hybrid, there are many car companies that produce plug-in hybrid models, such as BBA, Volvo, luxury brands and ordinary brands such as BYD, Geely, Buick, Great Wall and Volkswagen, but among these brands, we recommend BYD most. There is only one reason, and that is the warranty.
Of course, BYD still has some advantages in the three technologies of motor, battery and electronic control, and can realize independent research and development and production. Moreover, BYD's plug-in hybrid models often have strong acceleration ability. However, the acceleration of many plug-in hybrid vehicles is not weak when the motor and engine exert the same force. The real advantage of BYD hybrid is the warranty when the blade battery has not been applied.
You know, the highest cost of plug-in and hybrid models is not the engine and gearbox, but the power battery. Many luxury brands, such as BMW 530LE, need more than 200,000 yuan to replace the power battery once, which is close to half the price of a new car. This is also the biggest problem for plug-in and hybrid models. The current battery technology is still difficult to avoid the problem of life decay, and even for ordinary brands, the cost of replacing power batteries is tens of thousands of dollars, which also makes many people who were originally interested in plug-in and hybrid operation.
The warranty period of BYD hybrid non-operating vehicles is 6 years or 654.38+0.5 million kilometers, the warranty period of core components is 8 years or 654.38+0.5 million kilometers, and the power battery core is guaranteed for life. In addition to replacing the battery for free when the battery loss exceeds 30% during the warranty period, BYD Hybrid also provides a lifetime warranty for the battery. The owner can maintain a certain capacity of the battery through the battery cell warranty, and the battery cell is guaranteed for life. In this regard, BYD is the most conscientious of all car companies at present. At present, due to the technical difficulty of battery replacement, many BYD 4S stores directly replace batteries to ensure the quality of power batteries.
So if you choose a plug-in hybrid model, BYD's battery warranty policy will reduce your use risk and your car cost. If you choose a hybrid vehicle, shine on you Honda Hybrid is a better choice.
Speaking of hybrid, I have to talk about our domestic new energy brother, BYD. As we all know, BYD's hybrid and electric technology is now the top in the world, and many countries even introduce BYD's Xing energy models. Moreover, the recent news of cooperation between BYD and Toyota in the field of new energy has been continuously announced, which is enough to show BYD's pivotal position in the field of new energy.
If we must recommend a hybrid model with high cost performance, then I mainly recommend BYD's Tang. This model can be said to be the flagship model in the new energy field, representing the highest level in the domestic new energy field. This car has always been highly concerned, especially after BYD launched a brand-new family-designed Longyan, which attracted consumers' attention and can be said to be gorgeous. So what's so fascinating about it?
First of all, its face value, both in appearance and interior, caters to consumers' aesthetics and makes people deeply attracted at a glance. The appearance of Longyan design and the interior with full sense of science and technology make people fondle it.
The second is its configuration. It can be said that the current mainstream configuration is standard. Others have it, others don't. This is also a point that BYD has always attracted consumers, that is, the low price allows you to enjoy things that only luxury cars have.
The third is its zero acceleration, which reached an exaggerated 4.5 seconds. This can be said to be a rather scary data, and many luxury sports cars abroad are just like this. No one dares to say that the acceleration is the second in the country.
In addition, its fuel economy, the comprehensive fuel consumption of the hybrid version is about 2 liters per 100 kilometers, which is very fuel-efficient. Because it is hybrid, it solves the driving concerns of pure electric vehicles.
Finally, talk about its price. Compared with the expensive prices of some foreign new energy vehicles, BYD's subsidy price is still very close to the people, which is why it was once popular in the market.
To sum up, if you really want to buy a hybrid model, I recommend this hybrid Tang, which is very cost-effective.
Qin pro Hybrid Super Edition is the first choice for cars. Even in the case that the fuel consumption of oil-type vehicles is even lower than that of Corolla hybrid vehicles, the conditional charging of pure electricity can reach 53 kilometers, commuting in urban areas only costs a few cents a day, and the long-distance high-speed fuel consumption is less than 5 liters. The most critical price is only 13.69, which is 5.9 seconds faster than any steel gun. It can be said that it is a hybrid product with the best fuel economy and low price performance.
Schools of English poetry
There are two kinds of hybrids in the world, one is called Toyota activity, and the other is called other activities. Try your delicacies.
Which is more suitable for us to use? I will vote for Toyota. Toyota cars and batteries can directly drive the wheels, while Honda cars only charge the batteries, and the wheels are driven only by motors. From the perspective of "meeting the needs of the public", of course, Toyota is better. On the one hand, the reliability of this set of things has been tested, and there will be no concerns about reliability. And domestic for so many years, the cost control is quite excellent. Corolla with zero price difference is a good example. Honda's hybrid car is hardly cheaper than Toyota's hybrid car, and Toyota is higher in terms of cost performance. Moreover, after the new Accord hybrid version was made in China, the battery also shrank and became a lithium battery, which was more dependent on the battery than the Toyota hybrid system, but the battery shrank, which is undoubtedly a big hidden danger. Although the entry-level model is 40,000 yuan cheaper, the configuration is also several levels worse, so the price advantage is still wet. Although I have better power experience and lower fuel consumption, considering the stability, reputation and possession of my home, I still recommend Camry dual engine.
Mixed domestic BYD and weak Honda.
