Buying a car has become a problem that everyone will consider, especially when the car is gradually becoming the first choice for travel and transportation, and the price is becoming cheaper and cheaper. In fact, with the continuous upgrading of the concept of environmental protection, new energy vehicles have gradually entered people's vision, especially pure electric vehicles, and the state has subsidies when buying cars, which is undoubtedly a good choice. But in fact, now people buy cars is not only limited to pure fuel or pure electric vehicles, hybrid vehicles are also more and more popular with people.
BYD DM hybrid system has long been famous, the Great Wall is not willing to show weakness released the lemon DHT hybrid system, Chery brought the Kunpeng DHT hybrid system, Changan followed by the release of the Blue Whale iDD hybrid system, Geely Automobile released the Thor power hybrid system in the finale.
Nowadays, the sales of BYD's DM-i hybrid system have proved their absolute strength in the era of new energy vehicles, Chery Tiggo 8 PLUS Kunpeng e+ is low-key listed, and Great Wall WEY wants to get a share of the hybrid car market with latte DHT.
Domestic hybrid vehicles have been released, looking at the advantages of these hybrid vehicles, many consumers are eager to move, and they can't wait to buy a hybrid car.
The collective efforts of independent brands to hybrid vehicles show that independent brands have core competitiveness on the new track, but for consumers, if they really want to buy hybrid vehicles, I recommend that you think twice.
There are many advantages and disadvantages of hybrid vehicles, which are not suitable for all people, and I will analyze them in detail, hoping to bring valuable information to readers.
First, the difficulty of hybrid vehicles
In the current automobile market, there are fuel vehicles, gasoline-electric hybrid vehicles, plug-in hybrid vehicles, extended range electric vehicles, pure electric vehicles, of which the lowest technical difficulty is pure electric vehicles.
There is no difficulty in building an electric vehicle in China, as long as the PPT is well-spoken and there is sufficient funds, most electric vehicle companies are not building cars, but "assembling cars".
The exterior interior can be designed by an outsourcing company, batteries, electronic controls, and motors can be purchased by core suppliers, and then find a foundry to assemble these parts, and finally they can be sold off the line!
In addition to the car logo is designed by themselves, there is no technology on the whole car that is developed by themselves.
Plug-in hybrids are different, they have 2 sets of power systems, the technical difficulty of which is to reasonably distribute the power, so that the hybrid vehicle can reduce fuel consumption while increasing the power.
The core idea is to use the motor to adjust the speed and load of the engine, so that the engine works in the high efficiency range, so as to achieve the purpose of reducing fuel consumption, the current independent brands have their own solutions, most of the technology is relatively advanced.
The working principle of BYD DM-i super hybrid: a high-power generator is driven by a high-efficiency engine to power the drive motor, and in the medium and high-speed driving conditions, the engine is directly driven at the right time or paralleled with the drive motor to output the power.
The DM-i hybrid system is an electrically oriented and oil-supplemented design idea, which is essentially different from the oil-based Toyota dual-engine hybrid system.
Great Wall's DHT hybrid system adopts a dual-motor hybrid structure, which can be pure electricity, parallel connection, series connection, and can also realize two-speed engine direct drive.
With the addition of more drive modes and gearboxes, great wall DHT hybrid technology can achieve a balance of high performance and high performance in a larger working area.
Whether it is BYD's DM-i or the Great Wall DHT, the engine is a very important part, without a high-quality plug-in and hybrid special engine, even the best hybrid system can not play an advantage.
We can see that BYD before the launch of the Xiaoyun engine, the engine used by the hybrid car is the same as the fuel vehicle, although the DM dual-mode system is very strong, but the engine has been dragging its legs, and the early Tang DM is very noisy in the state of power loss, and the fuel consumption is also very high.
Now BYD has a Xiaoyun 1.5L high-efficiency engine and a Xiaoyun 1.5T high-power engine, which fills the shortcomings of BYD in the hybrid car, and the fuel consumption in the state of power loss is low and the noise is also small.
Great Wall also matched its own lemon DHT with 1.5L and 1.5T plug-in hybrid special engines, and Chery's Kunpeng power is the same.
It can be proudly said that in the field of plug-in hybrid vehicles, independent brands are taking a road of independent innovation, rather than imitating and borrowing in the era of fuel vehicles.
Plug-in hybrid vehicle technology is more difficult than pure trams, so so far only BYD and Roewe hybrid vehicles have appeared earlier, while other independent brands have only been released and listed so far.
Second, the advantages of hybrid vehicles
I am a relatively early batch of hybrid owners, the advantages of hybrid vehicles relative to fuel vehicles are strong power, low fuel consumption; compared with pure electric vehicles, the advantages are oilable and electric, long mileage, no mileage anxiety.
For some limited license cities, in addition to the Beijing area, plug-in hybrid vehicles can be green cards, and can be exempted from purchase tax when buying cars, which can save a lot of money compared to fuel vehicles.
I drove a hybrid car for nearly 4 years, and found that the biggest advantage of the hybrid car is that when driving in the urban area, when encountering a long-term traffic jam, the fuel vehicle engine is in a long-term idle state, not to mention the cost of fuel, long-term idle speed is easy to cause the engine to form carbon deposits, causing some impact on the follow-up car.
Plug-in hybrid vehicles encounter traffic jams are completely different, low speed can be pure electric driving, the engine does not participate in the work, the motor has no energy loss when parking, and low-speed driving is very energy-saving.
In the traffic jam is easy to be anxious, another advantage of the plug-in hybrid is that there is no noise generated by engine idling, the car maintains a relatively quiet environment, and the comfort is good.
My last plug-in hybrid has retired, the newly proposed plug-in hybrid has been 21 days, the cumulative driving of 1285km, mainly in urban areas, the average energy consumption of 100 kilometers: 9.0 kWh electricity + 2.6L oil.
As a medium-sized SUV with a weight of 2.2 tons, such energy consumption performance is already very good, and the fuel saving of the hybrid vehicle is visible to the naked eye.
There are advantages, naturally there are shortcomings, the shortcomings of hybrid vehicles are different from person to person, but they are objectively existent, I simply summarized the 5 major shortcomings.
The first disadvantage is that hybrid vehicles are prone to oil emulsification, high maintenance frequency, and increase the cost of using the car
Toyota Dual Engine is prone to oil emulsification, which is not a problem with Toyota engines, but a common problem of hybrid vehicles.
Yao Chunde, a professor at Tianjin University and deputy director of the State Key Laboratory of Combustion of internal combustion engines, once explained this phenomenon: "When the engine stops running, the PCV control valve closes, the crankcase forced ventilation system stops circulating, and the water temperature in the engine rises above the chamber under the action of high temperature (above 100 °C), and when it encounters the cold air inside and outside the valve chamber cover, it condenses into water droplets and mixes with oil and gas into a so-called yellow-white milky mixture, adhering to the top of the valve chamber cover." ”
"That is, the white milk we see, which is a phenomenon that occurs more or less in all cars, does not mean that there is a problem with the manufacturer's product, but the inevitable result of the combination of the engine working process and the specific natural environment."
Hybrid models will use electric motors to drive under conditions such as cold start and low-speed driving, and the engine will not run at this time to achieve the purpose of saving fuel.
Due to the low ambient temperature in winter and early spring, many people often drive short distances and low speeds, resulting in short engine running time and low working temperature, resulting in oil emulsification near the oil filling port.
Hybrid car oil emulsification phenomenon is unavoidable, now many car companies in order to avoid the occurrence of oil emulsification phenomenon, the most direct and effective way is to shorten the maintenance cycle, so that the oil has not yet appeared emulsified when the replacement of new oil.
Although this avoids the phenomenon of oil emulsification, the maintenance cycle is shortened, and the additional maintenance costs need to be borne by the owner himself.
Hybrid vehicles are higher in maintenance costs than fuel vehicles and pure electric vehicles, which may be one of the reasons why many car owners regret buying hybrid vehicles.
The second disadvantage is that the hybrid vehicle is generally noisy in the state of power loss
As mentioned earlier, plug-in hybrids are very dependent on the engine, and the durability of the engine, NVH, and fuel consumption determine the performance of the hybrid.
Although major car companies have developed special engines for plug-in and hybridization, in the state of power loss, when the full power output of the engine is required, the obvious noise and steering wheel shaking can still be felt.
This phenomenon occurs not only on plug-in hybrids, but also in Toyota's oil-electric hybrids, where engine noise is very pronounced when the battery is dequeficient.
Hybrids are particularly prone to the formation of two extremes, and the quietness is very good when fully charged, which can maintain the same NVH as pure trams; the noise is very obvious when the power is lost.
Accustomed to a quiet driving environment, suddenly hearing the noise of the engine, this contrast will amplify the effects of the noise in the mind.
This is where many people complain about the hybrid car, in fact, the engine noise is indeed very large when the power is lost, but it is definitely not so big that it is abnormal, and it is smaller than the noise of some fuel car engines.
The third disadvantage, the hybrid car is also afraid of the cold, the pure electric cycle mileage in winter is seriously reduced, and the cost of the car is doubled
Pure tram is afraid of the cold, the mileage will be halved, the same is true for plug-in hybrids, my hybrid car pure electric endurance of 112km, because it has been in winter since it was bought, pure electric mileage performance is not satisfactory.
According to the winter endurance measurements made by Zhichedi, the ideal ONE endurance achievement rate is 31.5%, Tang DM endurance is 44.6%, and Honda CR-V PHEV endurance is 45.4%.
Whether it is a plug-in hybrid vehicle or a range extender electric vehicle will be affected by low temperatures, the endurance achievement rate is less than 50%, because the pure electric mileage of the hybrid vehicle is short, which causes the pure electric endurance performance in winter is very general.
Pure electric endurance to achieve less than 50%, will also cause the cost of the car to increase, to Tang DM-i as an example, full charge needs 21.5kWh, that is, 21.5 kWh, household electricity 0.5 yuan one kilowatt-hour electricity, full charge needs 10.75 yuan.
In theory, 10.75 yuan can drive 112km, but in fact, 10.75 yuan can drive less than 56km, and the cost of the car in winter will be doubled.
The cost of the car is also related to the electricity bill, household appliances are cheaper, the charging pile is more expensive, basically more than 1 yuan / kWh, and some charging stations also need to charge parking fees, and the cost of the car will be further increased.
That is to say, although the hybrid car is more fuel-efficient, the winter electricity cost is not low, and the cost of using the car is much higher than that advertised, and many people regret it because the gap between expectations and reality is large.
The fourth disadvantage, the hybrid vehicle is basically a daily charging, relying heavily on charging piles, and needs to buy a separate parking space
The winter battery life of hybrid vehicles has been seriously reduced, and in order to maintain the advantages of fuel saving of hybrid vehicles, it is necessary to ensure that electric vehicles are driving in a sufficient state of electricity.
I drive 50km back and forth every day, the electricity at home is less than 39%, if you don't charge in time, the next day you will lose power, every night when you go home, the first thing to do is to charge the hybrid.
It is easier to use a hybrid vehicle with a charging pile at home, but if there is no charging pile at home, it is often possible for the hybrid vehicle to lose power, and the fuel consumption will rise in a straight line, and affect the service life of the power battery.
If you go to the charging station to charge, the fast charge is about 1 hour, and the slow charge is about 4 hours, and it becomes very inconvenient to use the hybrid.
To buy a plug-in hybrid, you also need to buy a fixed parking space, only the parking space is installed with a charging pile, and the hybrid vehicle is more worry-free and money-saving.
If there is no parking space, the cost of buying a parking space can be much more expensive than that of a car rental space, and the cost of the hybrid car is really cheaper than that of fuel vehicles? This is a question that everyone needs to think about.
The fifth disadvantage is low retention rate and poor liquidity
At present, plug-in hybrid vehicles and pure trams are facing the problem of low retention rate, and many second-hand car dealers are reluctant to buy plug-in hybrid vehicles, the main reason is that they are afraid of falling in their hands.
Fuel vehicles can be easily through observation and actual driving experience to assess the general condition information, pure tram and plug-in hybrid vehicle is completely different, the power battery attenuation information can not be found through test drive and observation, there is no special inspection of battery attenuation information instruments.
Second-hand car dealers do not know the detailed status of the power battery, and the power battery accounts for a relatively high proportion of the cost of the vehicle, so they dare not rush to acquire second-hand new energy vehicles.
Now the situation of plug-in hybrid vehicles is more embarrassing, second-hand car dealers are reluctant to pay high prices, and car owners are reluctant to sell at low prices, resulting in poor circulation.
According to the retention rate data given by a platform: the 3-year retention rate of the fuel version of the 5 series is 76.03%, and the 3-year retention rate of the 5 series of the plug-in and mixed version is only 52.61%.
Fuel version of Lynk & Co 02, 3-year retention rate of 62.14%; plug-in version of Lynk & Co 02, 3-year retention rate of 50.24%.
Therefore, the owner of the plug-in hybrid car must accept the disadvantages of low retention rate, and only the longer he uses it, the more suitable it is to buy a plug-in hybrid.
Write at the end
Plug-in hybrids and pure trams represent future development trends, its advantages are obvious, but the shortcomings also exist objectively, I do not regret it, but I like the advantages of hybrid vehicles.
In my opinion, if there is a fixed parking space at home, and objectively understand the advantages and disadvantages of plug-in hybrids, there are such conditions and mentality, it is more suitable for buying hybrid vehicles. Only by accepting the shortcomings of plug-in hybrids can we enjoy its unique advantages, otherwise it is easy to regret some problems. What do you think about that?
