Last Friday's push "not slower than oil prices, Tesla, Euler, Weima and other pure electric brands to raise prices", Jianghujun shared with everyone the current oil prices and pure electric models price increases. Considering the cost of the car and the anxiety of mileage, the hybrid model may be a more balanced choice at present.
So, the most common "four major hybrids" in the market at present: 48V micromixing, HEV oil-electric hybrid, PHEV plug-in hybrid and extender hybrid, do you know their advantages and disadvantages? Next, the jianghu jun combined with some models to talk about which angles should be considered for the type of hybrid model selected.
48V micromix
Advantages: low cost of increase, increased comfort
Disadvantages: The fuel saving effect is average
Representative models: Audi A8, Cadillac XT5
The emergence of 48V micromixing is mainly used to cope with the increase in power consumption of the vehicle's own electrical system. With the advancement of internal combustion engine technology, the compression ratio increased, and the earliest 6V motors were no longer enough to start the engine. So, in the 1970s, 12V power systems became mainstream and continued until around 2010.
In recent years, the intelligence of automobiles has been continuously upgraded, and the electrical system has become complex, which puts forward higher requirements for the output power of the power supply system. Not only that, in 2013, the European Union promulgated the Automobile Carbon Dioxide Emission Standard Act, which officially formed "carbon emissions" into regulations. The 48V micro-hybrid can reduce vehicle emissions and meet electricity demand at a low increase cost.
Therefore, European car companies are the first to apply 48V micro-mix technology, including well-known Audi, Mercedes-Benz, and other luxury brands; since then, 48V micro-mix has gradually become popular.
Theoretically, 48V micro-mixing has a fuel-saving effect, the fuel saving rate is about 14%-17%, and the fuel consumption will be close to 1L of fuel consumption savings. At the same time, with the assistance of 48V micromix, the engine will start more smoothly, the jitter will be smaller, and the comfort will be better.
HEV oil-electric hybrid (non-plug-in hybrid)
Advantages: Significantly lower fuel consumption, no need to recharge
Disadvantages: Can't get a "green card"
Representative models: Toyota Corolla Dual Engine, WEY Macchiato HEV
Today, most of the people who mention this technology will first think of Toyota, which has a long application time, a high penetration rate of models, and a good reputation among users.
Today, Toyota's THS hybrid has evolved to the fourth generation, and in terms of fuel saving rate alone, it can reach about 17%-18%.
The main reason for the gratifying fuel saving effect is because with the help of the motor, the engine can work in the efficient area in most cases.
In addition, the self-owned brand HEV has also made great progress in the past year. Great Wall Motor's DHT lemon hybrid, has been the first to be installed on WEY's Macchiato model, consisting of dual motors + engines, and Toyota's difference is that its working logic is based on motors, supplemented by engines. Moreover, the Great Wall DHT lemon hybrid supports both HEV and PHEV forms.
PHEV plug-in hybrid
Advantages: Can be on the "green card"; solve the mileage anxiety
Disadvantages: High fuel consumption without electricity
Representative model: Qin PLUS DM-i
When new energy vehicles first emerged, plug-in hybridization was once considered a transitional technology. But from the current point of view, the status of plug-in hybrid models is slightly awkward. At present, the most typical, most car companies are on the basis of their own HEV oil-electric hybrid, by increasing the capacity of the battery pack, improving the pure electric mileage and achieving plug-in hybrid technology, its technical logic is actually almost the same as the HEV model.
However, the DM-i hybrid system launched by BYD is a PHEV technology from the beginning of development, and the pure electric mileage of BYD DM-i models is generally higher (up to 120km), which allows consumers to experience the economy of pure electric vehicles (sufficient power and convenient charging) and the convenience of fuel vehicles (which can run long distances).
From the perspective of development trends, the technical bottlenecks faced by pure electric models, I believe that more car companies will start to develop plug-in hybrids. Next, plug-in hybrid models of large-capacity batteries may be further recognized by consumers.
Extender hybrid
Advantage: Solve mileage anxiety
Disadvantages: Low penetration
Representative models: Nissan e-POWER Xuanyi, Ideal ONE
We mostly learn more about this hybrid form through the ideal ONE, in fact, before that, Nissan e-POWER has achieved good results in the Japanese domestic market.
Its working principle is somewhat similar to THATV, which is also composed of an engine and an electric motor, except that the engine acts as a "range extender" and is not directly used as a driver, but only as a generator to charge the battery or power the driving motor. To put it bluntly, range extender hybrids all rely on electric energy to drive the driving. Since the engine is not involved in driving the vehicle, it can always operate in an efficient range.
Because the engine can continuously power the battery, it does not have to be equipped with a larger battery pack, and the interior space layout is more flexible; moreover, the manufacturing cost is only slightly higher than that of the gasoline version, and the terminal price will be more affordable than that of pure trams.
In theory, range extender hybrid solves the problems of fuel consumption, mileage, charging, etc., and can have a more comprehensive experience of using the car. However, it is worth mentioning that since the application time of this technology is not long, quality problems still need to be tested by the market.
Write at the end
For now, until the mileage anxiety is completely solved, the internal combustion engine cannot be completely abandoned in a short period of time, and the cost of the car is a problem that every car owner must consider. Then, the hybrid model is a transitional product that is more suitable for us at the moment.
The above four more mainstream hybrid technologies have their own advantages, and we may wish to refer to them when buying a car. If you have any other questions, please feel free to discuss them with jianghu jun in the comments section.
