On the road of energy saving and emission reduction, China’s goal is very clear. Vigorously developing new energy vehicles and realizing curve overtaking in the automotive industry should be the main goals of the automotive industry in recent years. However, the actual situation is that most of the new energy vehicles on the market are actually pure electric vehicles.
Although after years of development, the operating quality of pure electric vehicles has been greatly improved, the battery life and charging issues have become the main reasons why consumers refuse to buy pure electric vehicles. These problems are difficult to solve in a short time, at least the construction speed of charging piles is difficult to meet the charging demand of pure electric vehicles.
Perhaps the country is also aware of this problem. In the "Energy-saving and New Energy Vehicle Technology Roadmap 2.0" revealed at the Global New Energy Vehicle Supply Chain Innovation Conference held on September 16, there is a very important content:
Traditional cars will develop towards energy saving, while energy-saving cars will develop towards hybridization, and finally realize the integration of energy-saving cars and new energy cars through full electric drive.
Although the ultimate direction is pure electric drive, it is believed that the final release of the "Energy-saving and New Energy Vehicle Technology Roadmap 2.0" will make more car companies willing to develop and produce hybrid models. And because of the presence of the internal combustion engine, the hybrid vehicle does not have to worry about battery life.
There are currently three mainstream hybrid models on the market, petrol-electric hybrid, plug-in hybrid, and extended-range hybrid. What is the difference between them? What are the advantages and disadvantages of each?
"Buy a hybrid, save gas!" When I bought a car, many people told me that. The concept of gasoline-electric hybrid fuel-saving has been deeply rooted in the hearts of the people.
The biggest difference between oil-electric hybrid vehicles and traditional pure oil vehicles is the addition of three things: batteries, electric motors, and generators. The basic principle of operation is that the engine drives the vehicle. During the driving process, part of the power is used to generate electricity and store it in the battery, and then use the electric motor to drive the vehicle when the battery is sufficient, so that the engine and the electric motor alternately operate to achieve the goal of fuel saving.
At present, there are Toyota and Honda brands that mass produce gasoline-electric hybrid models on the market. The hybrid technology of these two companies is also different in details.
Vehicles equipped with Toyota's THS hybrid technology do not have a clutch. There are only two modes of pure electric drive and gasoline-electric hybrid. There is no pure fuel mode. The daily driving is based on hybrid, supplemented by pure electricity, and the engine and electric motor work alternately all the time.
The models equipped with Honda i-MMD hybrid technology have an additional pure engine drive mode, which maintains a stable and efficient engine operation mode when cruising at high speeds, and does not use part of the energy for charging.
As for which hybrid technology is better, there is no final conclusion on the market. It is recommended that friends in need can take a test drive and experience it.
Plug-in hybrid PHEV
The plug-in hybrid vehicle can be regarded as a combination of the advantages of pure electric drive and gasoline-electric hybrid. It can be used as a pure electric vehicle or as a hybrid vehicle. It is known as the best car form at present and is also a new energy recognized by the country One of the car types. Therefore, most car companies have developed plug-in hybrid technology, such as Volkswagen GTE, Toyota e-Hybrid and BYD DM.
Unlike gasoline-electric hybrid models, plug-in hybrid models have a larger battery capacity and therefore support the use of charging piles for charging. The pure electric cruising range will generally be more than 50 kilometers. For short-distance travel, such as daily commuting to and from get off work, plug-in hybrids do not produce any fuel consumption.
When the battery is fully charged, the hybrid driving mode is turned on. Because the battery has sufficient power and the kinetic energy of the electric motor is recharged at all times, the plug-in hybrid model can be better than the gasoline-electric hybrid model before the battery is exhausted. Lower fuel consumption.
In addition to the EV pure electric mode and the HEV hybrid mode, some models will also provide additional driving modes. For example, the Volkswagen GTE mode will start the engine and the electric motor at the same time to provide explosive torque and power, or BMW.
Extended program hybrid EREV
Although it is also a plug-in hybrid model, the biggest difference between the extended range model and other plug-in hybrid models is that the hybrid mode has become an extended range mode. The motor is driven throughout the entire driving process, and the engine runs at the highest efficiency to provide power to the generator.
Since the engine does not provide power for the vehicle, the engine specification of the extended-range model is lower than that of the plug-in hybrid model, which can reduce the cost of vehicle manufacturing and fuel consumption.
Using oil to generate electricity and then using electricity to drive, there are two energy conversions, and there is energy loss in the conversion process, so the controversy in the market for extended-range hybrid models is still quite large.
One of the more out-of-the-loops is that the CEO of Volkswagen China said some time ago that the program extension is an outdated technology and has no development prospects. Ideal cars responded positively and hoped to compare the fuel consumption of Leading Ideal ONE and Volkswagen Group's plug-in hybrid models to see who is more energy-efficient and environmentally friendly.
There are no absolute advantages or disadvantages of hybrid, plug-in hybrid, and extended-range hybrid. For consumers, it still depends on the specific situation. For example, if you are in a city where the number is restricted, then the hybrid electric vehicle does not belong to the category of new energy vehicles and will be eliminated first.
For those with long-distance driving needs, plug-in hybrids are obviously more suitable than pure electric vehicles. As for the extended-range hybrid, anyway, only a medium and large SUV is in use, so buy it if you need it.
