Traditional gasoline vehicle electric vehicle
At the beginning, the country vigorously promoted electric vehicles, and various policy support and subsidies made the price of electric vehicles very low. However, most people think that the development time of electric vehicles is too short and the technology is not mature enough, so they buy them rashly. However, the tanker has a history of hundreds of years, and the characteristics of major brands are deeply rooted in the hearts of the people, and the prices have also taken care of everyone. So at first, most people refused electric cars. Nowadays, with the soaring oil price and the reduction or even cancellation of tram subsidies, many friends have begun to shake their faith. Should I buy a petrol car or a tram for the first car?
Objectively compare the characteristics of tanker and tram;
Oil tanker:
1, the tanker is more mechanized, so its performance is stable and it can be used for decades after good maintenance;
2. It is convenient to refuel and there are many gas stations, so it is not a big problem to use in harsh environment (but the engine requires high oxygen content in the air and is weak at high altitude), and it is easier to repair after being damaged;
3. Gasoline, engine oil and other lubricating oils have high quality requirements. If the maintenance is not good, it will easily affect the normal use, and consumables need to be replaced regularly;
4. The exhaust gas emitted by the oil tanker also pollutes the atmosphere to a certain extent, and it is easy to accumulate carbon when parked in the state of the car, and there is also the risk of carbon monoxide poisoning;
5. The engine belongs to internal combustion engine, and its low output torque requires that the tanker must be equipped with clutch, transmission and main reducer to drive a car weighing tons. With so many accessories, the mechanical parts occupy a large space, and the seating space in the car is compressed. However, it is precisely because of the torque output characteristics of the gasoline engine that the tanker can start smoothly. Even if the throttle valve is fully open, the maximum torque cannot break out at any time, and the increasing acceleration makes people less prone to carsickness than trams.
6. The internal combustion engine has been developed for hundreds of years, but its working principle determines its low output efficiency and great heat loss (in recent years, the thermal efficiency of the ignition engine developed by Mazda's new technology reached 43%, ranking first in the world at that time, and the recently developed compression ignition engine only exceeded 50%). It can be said that the problem of heat loss has not been well solved for hundreds of years.
It's like a box of gasoline costs you 400 yuan, and less than half of the gasoline is used to make the car run. Most of the burning of gasoline is converted into heat dissipation, and you can't even hear a sound. However, in winter or cold areas, engine heat is an excellent heating system, which will not greatly increase energy consumption because of winter heating like trams;
7. The unique exhaust sound of gasoline engine is loved by many fans, and it is also called the natural sound of various large-displacement cars, which is also a unique knowledge. The so-called driving pleasure is also closely related to the exhaust sound.
Trams:
1. From the structure of the tram, compared with the tanker, the motor of the newly designed electric platform tram is much smaller than the engine transmission system (the battery is arranged under the car, so the driving motor itself is much smaller than the engine, and the tram does not need many complicated water pipes, generators, clutches, transmissions, main reducers, etc. ), cars with the same volume can leave more space for the passenger compartment;
2. The tram has no exhaust system, and there is no exhaust pipe passing under the floor, which means that the back floor of the tram can be flat, without middle arching, and the rear riding experience will be much better than that of the tanker; At the same time, there is no tail gas, which means that the tram can achieve zero pollution in the case of traffic jam, and there is no risk of poisoning when parking in the car state;
3. As far as the output characteristics of the driving motor are concerned, the middle and low speed sections are all constant maximum output torque (the wheels can be directly driven without the main reducer, which is much larger than the tank car, and there are fewer accessories to save space), which can be understood as that the electric switch can generate the maximum acceleration force in the initial acceleration stage, which makes the tram very flexible on low-speed roads in urban areas.
But the latter part is weak, because the torque in the high speed range is getting lower and lower, which is the characteristic of the tram, so that its maximum speed will not be too high (as can be seen from the diagram of the motor torque-speed curve). However, due to the rapid response of electric drive and the kinetic energy recovery system of tram (similar to engine power), once the driver is not good at driving, passengers will easily get carsick;
At present, the biggest problem of trams is battery life and charging speed. Due to the limitation of vehicle size, long battery life means large batteries, carts are generally more expensive, and they cannot be as small and fuel-efficient as oil trucks (such as Honda Fit), and the charging speed has always been inferior to oil trucks. Add a tank of oil for three to five minutes, and charge 60% of electricity in half an hour. The closer to 100%, the slower the charging speed will be, and the battery will be replenished when driving for a long distance.
5. Compared with the oil tanker, the output of the tram will not be weakened because of the thin oxygen at high altitude, but will only be affected by the temperature, and its endurance in cold areas will be greatly reduced (but over time, the battery heating and temperature control system will greatly improve this deficiency);
6. Because there are many electronic components, the stability of the tram is not as good as that of the tanker, which puts forward higher requirements for the quality control of the manufacturer, and it must be more strictly controlled than the tanker to have the ability to fight.
In today's society, the "28" rule still applies, and 80% of our young people are just ordinary people with average income, so when faced with buying the first car in life, they will be confused about whether to buy an oil car or a tram.
Look at the budget when you buy something. The budget of ordinary young people will certainly not be too high, and it is necessary to consider the cost performance. From the functional point of view, both tank trucks and trams have good cost-effective choices, so what needs to be considered and compared is the practicality and convenience of later use and the cost of use.
Practicality can be seen from two aspects: daily traffic and holiday travel. Now a large number of young people flock to big cities to work hard. Most of the daily traffic is urban roads, characterized by congestion, slow speed and short distance. There is no doubt that the tram won completely. From the point of view of travel, short-distance trips to Zhou Bianyou and other trams can also be easily controlled, while long-distance trips are better than oil cars, which are fuel-efficient and convenient to replenish energy.
Convenience depends on the effectiveness of the function, such as the start-stop system of the engine, which belongs to the recognized chicken rib function. It is inevitable that the car will break down in the process of use, and most of the failures of the tanker can give people sufficient disposal time (enough to stop by). Some known faults of trams are very serious (such as limited EV, black screen of operating system and even crash). ), which requires major car companies to continue to work hard to improve the stability of trams, and tank trucks have a slight advantage in this respect.
The later use cost is also a heavy consideration, which is undoubtedly a complete victory for trams. The cost of tanker includes the high cost per kilometer brought by gasoline price, the high cost of regular maintenance and the replacement cost of various lubricating greases.
Conclusion: Most people often consider all aspects when using a car. However, in fact, a car can't meet all the requirements. For example, commuting needs small, flexible and low-cost parking, going out for an outing needs comfort, and long-distance travel needs comfortable seats and stable functions. ...
So today I make a recommendation based on the car demand of contemporary young ordinary people:
Taking advantage of the national policy, the first automobile decisively chose electric vehicles, and the use cost of only one oil vehicle was less than one tenth. I didn't know it was "delicious" until I used it.
Maybe a friend will ask, what should I do if I want to go out to road trip for the battery life and charging of the oil car?
I just want to say: wake up! Everyone is a social animal. It can be said that 90% of the time in a year is spent in the city, and half of 10% vacation time may not travel for various reasons. There is no need to waste too much money for less than 5% of the time every year. What's more, the car rental industry is so developed now. If you plan to rent a car in advance when you go out, any problem can be solved!
Some friends will also say that the bare car price of your tram at the same level is tens of thousands more expensive than the oil car, which is enough for me to add more oil to the teenagers. In other words, do you know that it will cost money to change batteries in three to five years?
In fact, first, the trams of the same level are not much more expensive than oil cars, and the trams are mainly made in China, which have already taken off and have an advantage in price; Second, most manufacturers have the policy of lifetime warranty of Sanpower and free replacement of seriously defective batteries. And according to many old tram owners, the battery technology used five years ago can still be used today. You can rest assured in this respect.
Finally, if you really spend a lot of time on business trips every year (for example, some special industries need long-distance business trips), you can also choose to mix them ~ In short, in the current social situation, it is the best policy for tankers to drive in urban areas.
