New energy vehicles have always been a hot topic, but also the current hot automotive products, with the vigorous launch of the first new energy vehicles gradually into the homes of ordinary people. When it comes to new energy vehicles, we can't help but mention pure electric vehicles, which are the most representative of new energy models from the current perspective.
However, new energy vehicles are not only pure electric vehicles (BEVs), but also hybrid vehicles (PHEV, HEV), fuel cell vehicles (FCEV), etc., which of these new energy technologies will become the mainstream in the future, and it is not just a matter of which one is the most suitable automotive technology. This question involves the technology of supporting infrastructure, the policies of the major markets, the technology of energy development and smelting, the future prospects of nuclear power, the people's attitude towards nuclear power, the development of power grids, the development of autonomous driving technology, battery technology, the discovery of new fossil energy, and even the direction of international politics.
Levi Tillemann, author of The Greatest Race, says that no one can be sure which energy technology will be the best solution, not to mention that at the current level of technology, all renewable resource options are not perfect.
However, at present, many people are entangled in pure electric vehicles and fuel cell vehicles. However, the most fatal problem of pure electric vehicles is the problem of charging speed and range, and both problems have been solved in hydrogen fuel cell vehicles. As for battery life and cost, at present, pure electric and hydrogen fuel cells are both half a catty and eight taels, and neither is much better than the other.
The cost of a hydrogen fuel cell vehicle is no higher than that of a pure electric vehicle with the same range.
What's more, how to go in the new energy market, in addition to looking at the technology orientation, but also look at the mentality of the big players in the industry, and more importantly, the attitude of the big car market, so it is difficult to determine who will dominate the future of new energy vehicles.
-
The power of new energy vehicles will be pure electric, no battery, no charging, unlimited battery life, and lower price.
-
Compared with fuel vehicles, new energy vehicles have always existed, including natural gas, solar energy, electric and methanol, all of which belong to new energy vehicles! The current name is new energy is a professional name, new energy (NE): also known as unconventional energy.
It refers to various forms of energy in addition to traditional energy sources.
-
New energy vehicles refer to the use of unconventional vehicle fuel as the power (or the use of conventional vehicle fuel, the use of new on-board power units), the integration of advanced technology in the power control and drive of the vehicle, the formation of advanced technical principles, with new technologies, new structure of the car.
New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.

In the question, we are talking about "electric locomotives", that is, "electric locomotives, electric locomotives". It is divided into trams and trolleybuses. Trams are a type of "train", and today's high-speed trains (trains) are basically "trams".
Trolleybuses are the kind of city buses described in the question. Trolleybuses are rarely seen in our country. The main reason is that the cable over the city is "dirty and messy", and there are potential safety hazards.
And this kind of tram uses electricity in the traditional sense - mains, high-voltage, alternating current. And without the overhead wires, it will be difficult to move an inch.
Today's "electric vehicles" use "batteries", which do not need to be connected to overhead wires and can drive freely. This "electricity" is not the same thing as "electricity" in the traditional sense. This is direct current, low voltage electricity.

With the continuous advancement of modernization, the new energy vehicle industry, as one of the representatives of sustainable development, has risen rapidly in recent years and still occupies a great voice in the market.
In response to environmental pollution and energy crisis, the application and development of new energy vehicles have gradually attracted widespread attention from all walks of life. New energy vehicles have the characteristics of intelligent networking and high informatization.
Automobiles are an indispensable means of transportation in the field of social and economic life, but the wide application of automobiles not only brings convenience to people, but also causes a series of problems such as environmental pollution and energy shortage. Environmental protection, pollution reduction, energy conservation and emission reduction have become the consensus of global development. Due to low noise, less pollution, and green environmental protection, electric vehicles have gradually become an industry hotspot that has attracted more and more attention in the automotive field.
It is of great theoretical and practical significance for the healthy and sustainable development of China's economy to analyze the future energy consumption structure, formulate a scientific and reasonable energy production plan, and provide a scientific basis for the national energy policy.
In the new era, China's high-quality energy development needs innovation momentum. The integrated energy (system) concept proposed by the planning team of the Xiong'an New Area, a Chinese consulting firm, has been hailed as a "very advanced concept". Make full use of domestic low-grade energy, mainly electricity, natural gas and hydrogen energy, high-grade energy, adopt smart energy technology, and achieve multi-energy complementarity through the construction of integrated energy station projects + smart energy.
The microgrid project realizes the cascade utilization and recycling of energy, and realizes the one-stop service of cold and hot water. Its overall energy efficiency and energy reliability have been greatly improved, and users can enjoy a variety of energy package services, and can innovate energy management. It is a safe and advanced urban energy model.
The development of smart energy technology and the promotion of integrated energy, new energy infrastructure and new models and new forms of business will help improve the level of integrated development of energy and cities in China, greatly improve energy utilization efficiency and service levels, and help realize the green, safe and efficient energy production, transmission, storage, application and service of the entire industrial chain. With the continuous enhancement of people's awareness of environmental protection and the support of various favorable policies, new energy vehicles are becoming more and more popular, and there is a trend to gradually replace fuel vehicles. At present, the automotive market is mainly composed of three types of new energy vehicle products:
Incremental electric vehicles, battery electric vehicles, and plug-in hybrid electric vehicles. They demonstrate their energy-saving advantages over conventional fuel vehicles in different technical routes.
-
Because there will be no exhaust emissions in the process of using new energy, and there is no special smell to protect the environment, it is a trend advocated by automobiles in the future.
-
Because such a car is very good, especially recognized, very good, especially perfect, and also relatively environmentally friendly, so it can become a major trend.
-
Because it is more environmentally friendly to use this type of car, which is in line with the theme of human development.
-
Electric vehicles and new energy vehicles are not the same concept, it can only be said that electric vehicles are a kind of new energy vehicles. At present, the main new energy models in China's market are: pure electric vehicles, fuel cell vehicles, etc.
The reason why these models are called new energy vehicles is because they all use unconventional vehicle fuels (unconventional vehicle fuels refer to fuels other than gasoline, diesel, natural gas, liquefied petroleum gas, ethanol gasoline, methanol, and dimethyl ether) as power** (or use conventional vehicle fuels and adopt new on-board power units).
Like the gasoline-electric hybrid model, it is not a real new energy vehicle in nature, and it is destined to be excluded without fuel. It's just that there are still technical shortcomings in electric vehicles, and they are temporarily needed to make up for the needs of the market, which can be regarded as an excessive model.
Not only electric vehicles, fuel cell vehicles, but also with the development of technology, solar vehicles and even nuclear fuel cell vehicles may appear in our lives. The development of science and technology is inseparable from innovation, and the survival of human beings is inseparable from the environment.

Is an electric car a new energy vehicle?
-
New energy vehicles are relatively traditional gasoline and diesel vehicles, and new energy vehicles include pure electric vehicles, hybrid vehicles, and fuel cell vehicles. The range of new energy vehicles is larger.
-
Because of the use of unconventional vehicle fuels as power** (or the use of conventional vehicle fuels, the use of new on-board power units), the integration of advanced technology in vehicle power control and drive.
New energy vehicles include four types of hybrid electric vehicles (HEVs), pure electric vehicles (BEVs, including solar vehicles), fuel and recreation battery electric vehicles (FCEVs), and other new energy vehicles (such as supercapacitors, flywheels and other high-efficiency energy storage) vehicles. Unconventional vehicle fuels refer to fuels other than gasoline and diesel.
The advantages of new energy vehicles are:
1. Environmental protection of new energy vehicles. New energy vehicles are mainly used in the pure sale of non-fuel power units, which do not need to burn gasoline and diesel, but use clean energy, such as electricity, solar energy, hydrogen, etc.
In this way, the emission of gases such as carbon dioxide is reduced, which is the goal of protecting the environment.
2. Save money. The fuel cost of fuel vehicles is about yuan per kilometer, but the use of electricity only needs yuan. In addition, the structure of the motor is very simple and not easy to break, and does not require frequent maintenance.
3. New energy vehicles do not need to travel with limited numbers. Because of serious environmental pollution, in order to reduce environmental pressure, many cities have adopted the method of restricting the number of cars and restricting the travel of private mountain cars. However, new energy vehicles have almost zero pollution and zero emissions, so they are not within the scope of the limit, which is more convenient to travel.

Recently, the rapid rise of new energy vehicles, whether it is a national policy or enterprise promotion is a very good market opportunity. What is a new energy vehicle? As the name suggests, new energy vehicles refer to a mixture of traditional cars and new energy vehicles.
Conventional cars: gasoline engines, electric motors, etc. New Energy Vehicles:
It refers to new energy vehicles powered by lithium-ion batteries.
Lithium-ion battery: It is a lithium-ion battery that works with cobalt, nickel, lithium alloy and other elements to form an electrolyte, and then directly places it in the positive electrode of the lithium-ion battery to form a battery. At present, it is widely used in lithium nickel-cobalt-manganese oxide batteries.
Lithium-ion battery: It is a battery that uses the "lithium cladding" between lithium and cobalt atoms in the electrolyte to discharge and charge, and generate electrical energy. At present, lithium-ion batteries have been widely used in mobile phones, computers, automobiles and other fields.
Traditional cars: Because the engine cannot be started and can only be used as a car to drive, the main power used in traditional cars is diesel engines and gasoline engines. Because the car cannot be started, it can only rely on the battery to replenish the energy.
Electric vehicles: Since the car uses a lithium-ion battery as the powertrain**, the battery will be much higher than the traditional car in terms of energy conversion efficiency and battery capacity, which can provide strong power for the car. If a traditional fuel vehicle is used as an engine to drive the vehicle, the fuel consumption of a traditional fuel vehicle can reach at least 9 liters per 100 kilometers, while the use of electric vehicles can not only reach more than 5 liters per 100 kilometers, but also reach more than 100 liters.
Electric vehicles are powered by lithium-ion batteries, mainly because of the low cost of batteries. However, the cost of the battery determines the cost of the electric vehicle, and the final cost of the electric vehicle has a lot to do with the type of battery.
From the perspective of market demand, at present, the domestic electric vehicle market is saturated, the number of domestic electric vehicles is low, and the future market demand will still be imported. Therefore, the current new energy vehicles are more to meet the user's requirements for the best, rather than the real car demand. From the point of view, new energy vehicles are relatively cheaper, and the power consumption of new energy vehicles is about 7 degrees per 100 kilometers.
If you take into account the cruising range and ** two indicators. At present, the new energy vehicle market is saturated.
The cost advantage of electric vehicles is very obvious, and its cost of use is lower than that of traditional vehicles. Electric vehicles use electric motors instead of gasoline engines, which saves a lot of costs. And because batteries can be used to store electricity, the cost of batteries is much cheaper than gasoline engines.
Electric vehicles use traditional fuel engines, which are much more powerful than gasoline engines, and the cost is naturally lower than gasoline engines. Now, pure electric vehicles have occupied an absolutely dominant position in China, and more and more sales are in the Chinese market. However, pure electric vehicles are still in the early stage of promotion, and their main advantages lie in their cheapness, convenient charging, and strong battery life.

Electric vehicles can run normally, mainly by the on-board power supply, using the motor to drive the wheels. New energy vehicles use unconventional fuels as power**, which is a comprehensive vehicle. Whether it is the drive or the power control, it is a relatively advanced technology.
Humans are enjoying the convenience brought by technology, but at the same time, they are lamenting that technology is developing so fast that it is difficult to keep up with it. With the emergence of various high-tech technologies, human beings have finally landed in the far reaches of outer space by relying on the power of science and technology, and even the ocean is being explored. Many questions have been bothering scientists, and those who are keen on science fiction have wondered about the question, in what direction will humans evolve in the future? >>>More
