What is the energy source of new energy vehicles, and what is new energy for automobiles?

All energy vehicles other than gasoline and diesel engines are called new energy vehicles, which are more environmentally friendly and clean.

New energy vehicles include fuel cell vehicles, hybrid vehicles, hydrogen-powered vehicles, and solar vehicles. Its exhaust emissions are also relatively low. According to incomplete statistics, there are more than 4 million liquefied petroleum gas vehicles and more than 1 million natural gas vehicles in the world.

Here are the different kinds of cars:

1. Pure electric: refers to a vehicle that is only equipped with a power battery and driven by an electric motor.

2. Extended-range electric vehicle: refers to a vehicle that can be connected to an external charging power supply and an on-board charger and driven by an electric motor.

3. Plug-in hybrid: a hybrid vehicle that can be connected to an external charging power supply.

4. Non-plug-in hybrid: hybrid vehicles that cannot be connected to an external charging power supply.

New energy vehicles refer to vehicles powered by new energy sources, such as electricity, hydrogen, etc., and do not use gasoline, diesel or natural gas as the power. There is also a type of hybrid power, such as oil and electric drive at the same time.

The new energy vehicle technology major is a new energy vehicle shortage talent major based on the country's vigorous development of electric vehicles. Professional core competence of new energy vehicle technology: It has the ability to assemble, inspect, maintain and provide marketing services for automobiles and accessories for new energy cars.

Common new energy vehicles include: pure electric vehicles, extended-range electric vehicles, plug-in hybrid electric vehicles, fuel cell electric vehicles, etc.

Hybrid vehicles, hydrogen-powered vehicles, pure electric vehicles.

1.New energy vehicles refer to vehicles that use unconventional vehicle fuels as power**, or use conventional vehicle fuels but use new on-board power units. New energy vehicles often integrate advanced technologies in vehicle power control and drive, forming advanced technical principles, new technologies and new structures.

New energy vehicles include four types: hybrid electric vehicles (HEV), pure electric vehicles (BEV, including solar vehicles), fuel cell electric vehicles (FCEV), and other new energy sources, including mechanical energy vehicles (such as supercapacitors, flywheels, compressed air and other high-efficiency energy storage) and unconventional vehicle fuels (referring to fuels other than gasoline and diesel, such as natural gas (NG), liquefied petroleum gas (LPG), ethanol, gasoline (EG), methanol, and dimethyl ether).

2.Electric vehicle (BEV) is the use of electric energy as a power source, through the electric motor to drive the car, is now a more common type of new energy vehicles, the use of lithium-ion batteries and other batteries for the car energy, this kind of car structure is simple, more suitable for urban cars, but long-distance driving has the problem of endurance, but also face the problem of charging. The hybrid electric vehicle (HEV) is a car with two systems, some types can be driven by two sets of systems separately, some types are supplemented by the electric system, and the fuel system is still the mainstay, in addition to the plug-in hybrid electric vehicle (PHEV), this kind of car is more special

The battery can also be plugged into an external power source for charging. One of the contributions of electric vehicles to the environment is that they reduce vehicle exhaust emissions in the first place, reducing some of the corresponding pollutants, and at the same time saving some fossil fuels and reducing carbon emissions, because electricity** may be renewable energy, such as wind, solar, hydropower, etc.

The above two types of cars are better used and developed, and they are relatively common types.

3.Fuel cell electric vehicles (FCEV) are also electric vehicles in a sense, but instead of charging but refueling, the most common fuel is hydrogen, which is a clean, does not produce carbon dioxide, and has a large calorific value, but there are also many problems, such as hydrogen itself is a problem of storage, transportation, cost and safety, and there are problems with supporting facilities. In addition, the catalysts required for fuel cells are also expensive, such as the famous PT catalyst, and the cost of hydrogen makes the cost of fuel cell vehicles also high.

Finally, there are unconventional vehicle fuels, such as ethanol gasoline, natural gas, etc., there are many such applications, and it is easy to transform, this kind of fuel is often more fully burned than gasoline and diesel, and will not produce harmful substances such as nitrogen oxides, but it will still emit carbon dioxide, of course, there are also shortcomings, such as power reduction, shortened stroke, etc.

The core components of a pure electric vehicle are the battery, motor and power system, and the main maintenance projects are also carried out around these three parts. This is followed by the maintenance of braking systems, chassis inspections, lighting inspections, tire inspections and other items. The first task is the component that needs frequent maintenance, of course, is the power battery pack, and the vital importance of the power battery pack to new energy vehicles is also self-evident.

Car owners of new energy vehicles need to regularly maintain the condition of the power battery pack to prevent power loss of the power battery pack, and also need to pay attention to eliminating potential safety hazards.

Then there is the motor, which is the key component to drive the driving of new energy vehicles. Like traditional fuel vehicles, the motors of new energy vehicles also need to be replaced with coolant on a regular basis; Then there's circuit detection. Compared with the circuit of a fuel vehicle, the circuit of a new energy vehicle is much more complex, and at the same time the voltage must be much higher.

For our safety, we need to regularly maintain whether the joints are loose, whether the wiring is aging, and so on. Finally, in addition to the testing of the three-electric system of new energy vehicles, we also need to test the brake pads, tires and wipers and other commonly used wearing parts of new energy vehicles. For example, to detect whether the tire pressure is normal, whether the brake pads are aging, etc., must not be negligent.

Hello, bai new energy vehicles refer to the use of unconventional DU vehicle fuel as the power (or the use of conventional vehicle fuel, the use of new vehicle power units), the integration of vehicle power control and drive advanced technology, the formation of advanced technical principles, with new technology, 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, and other new energy vehicles. I hope it can help you, I hope to adopt, thank you!

A car that does not use traditional fuels is a new energy vehicle.

New energy vehicle technology is different from traditional fuel vehicle technology, using unconventional vehicle fuel as power**, or using conventional vehicle fuel but using a new type of on-board power plant, integrating advanced technology in vehicle power control and drive.

Compared with traditional fuel vehicle technology, new energy vehicle technology will effectively reduce emissions, improve fuel utilization, reduce the cost of use, and also have the advantages of stable operation and low noise, but at present, new energy technology is still in the stage of exploration and development, and the requirements for existing battery technology, precision mechanical electronic control technology and various supporting facilities are extremely high, and it will take time to further improve.

At present, new energy vehicles mainly include pure electric vehicles, extended range electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles. In 2001, the new energy vehicle research project was included in the "863" major scientific and technological projects during the national "Tenth Five-Year Plan" period, and planned the strategy of taking gasoline vehicles as a starting point and advancing to the goal of hydrogen-powered vehicles. The first stage is to develop the new energy vehicle market with hybrid vehicles as the mainstay, supplemented by fuel cell vehicles and other new energy vehicles; The second stage is based on the maturity of pure electric vehicle technology, pure electric vehicles gradually replace hybrid and fuel cell vehicles to completely occupy the new energy vehicle market and achieve zero emissions.
