"This hybrid system is indeed a development idea." After returning to the first machine factory, Qin Zhenhua called Wang Erzhu, Nie Qianqian and others and held a small meeting. When he heard that Qin Zhenhua was interested in this aspect, Wang Erzhu immediately introduced it.
Get up.
"After all, even if the country wants to promote pure electric cars through various means, charging is too troublesome after all. Especially once it is used in large quantities, it is also a great challenge to our domestic electricity supply, and for many automobile companies
In other words, it is almost equivalent to starting from scratch. Therefore, hybrid systems have a market for a certain period of time, which can allow today's car companies to smoothly transition to the future pure electric era." Wang Erzhu said.
"In recent years, our domestic sales of heavy-duty gas trucks have been booming. We can also see that the price of natural gas has begun to gradually rise. It is estimated that this fuel will have no advantage in less than a few years." Nie Qianqian also analyzed from the side:
"Pure electric vehicles now seem to be very cheap, with only a few cents of electricity per kilometer, but after that, the price may rise."
Nie Qianqian also understands this aspect. After all, as a media person, you must have a wide range of knowledge and have certain reasoning skills.
In the past, natural gas was very cheap and clean, so all heavy truck factories were launching natural gas heavy truck projects. This kind of heavy truck can save one or two thousand yuan of fuel expenditures over diesel heavy trucks. In this way,
Ten trips a month will cost 10,000 or 20,000 yuan. What you save is earning. Although when purchasing, natural gas heavy trucks are more than 100,000 yuan more expensive than diesel heavy trucks, you can get the money back in a year, and you can get it next
It's even more profitable. Therefore, natural gas heavy trucks have always been in short supply.
However, with the increase of heavy-duty trucks in natural gas, the demand for natural gas is increasing, especially in winter, many heating boilers have also begun to use natural gas, which makes the price of natural gas continue to rise, and soon, the advantages will be offset.
It's right.
In addition to these, another important problem is gas shortage. In winter, due to the increase in gas consumption, the gas filling stations may not have enough natural gas to supply cars. In this way, heavy trucks of natural gas have to stop.
I was so angry that those cars were bought with loans. I can’t run away now, and I have to pay back the loans on a monthly basis. They are under great pressure.
This is the case with natural gas heavy trucks. In the future, pure electric vehicles may also take this path when they develop. Now it seems that charging is very cheap, but after that, the price of commercial electricity will rise, and if so,
If the country's power supply is insufficient, my pure electric car may not be able to go on the road because it cannot be charged.
Under various concerns, pure electric vehicles are not completely favored, which also gives hybrid vehicles a space to survive. The so-called hybrid means that internal combustion engines and electric motors exist on the vehicle, so that they can be charged or
Come on, the power of choice is greater.
Qin Zhenhua seems to have become interested in this technology, so Wang Erzhu continued to introduce it: "Just talking about this hybrid, there are different ways, for example, the simplest is the parallel method, in this way,
It is still based on the engine as the main power and the electric motor as the auxiliary power. Generally speaking, the changes are made on the automobile generator and start motor. For example, in Germany, a 48v weak hybrid system is being developed, such as this system,
The circuit in the car has been changed to 48v, and a 48v battery was added to the car. At the same time, the starter motor and generator have been integrated into a starter generator. This motor may not be able to directly drive the vehicle forward, and its main
The method is to use the engine to drive the vehicle. However, when the car needs to start and accelerate, this motor is added to provide additional torque to help the car complete these actions. We also know that in these occasions, the engine needs to improve the power output and
It consumes more fuel, so just give it a try, so that the car can save fuel. This method is the simplest to transform existing vehicles, so it is also loved by some car companies. Of course, because
The modification is small, so the potential is limited. Another one should be more advanced and increase the output power of the motor. In this way, at low speeds, the motor can only drive the vehicle forward. The engine does not ignite, so we also
Know that in urban road conditions, stop and stop are the most fuel-intensive. At this time, the motor will provide the forward power. The engine does not work. Only when the speed increases will it be made by the engine and the electric motor.
Although this method is effective in common output power, because it is necessary to increase the working strength of the electric system, it is necessary to have a larger motor and battery, which increases more weight and is also complex in the internal structure. Especially when internal combustion engines are added
When working, if you cannot match properly, there will be a stuttering and bring discomfort to the passengers. In addition to these, there is another way, which is a more unique way. The engine is only used to generate electricity, and the power generated is given to
The electric motor provides, such a method is more extreme, and the specific fuel-saving effect is hard to say."
Gao Jiachen just talked about a hybrid power method that day, and now, Wang Erzhu talked about several methods to Qin Zhenhua. After introducing these, Wang Erzhu continued: "However, these are the driving methods on passenger cars.
, For commercial vehicles, especially heavy trucks, these are still far away. Director Qin, are you planning to conduct pre-research on this aspect?"
The main business of the first machine factory is tanks, and tanks do not need to be so troublesome, so Qin Zhenhua should ignore these things, but the automobile branch of the first machine factory is also an important source of profit. Moreover, Qin Zhenhua also
We know that if an enterprise wants to continue to grow and grow, it must be forward-looking and conduct pre-research in advance. We must not always sit and eat ready-made things and do not intend to make progress, which will eventually go bankrupt.
If Qin Zhenhua wants to develop a machine factory and a car branch, he must consider the future technical route. If he wants to continue to improve and save fuel, should he choose the right one in terms of power?
What about the technology upgrade route? Will trucks with pure internal combustion engines be eliminated at some point in the future? Qin Zhenhua was a little worried.
