Tuyi New Energy Vehicles said that they would sign a guaranteed contract of 1w2, with a deposit of 1w, and a monthly payment of 4600, and supply of goods would be provided. Are there any experienced drivers who have done it before? Are they reliable?

New energy vehicles refer to all other energy vehicles except gasoline and diesel engines. Including fuel cell vehicles, hybrid vehicles, hydrogen energy-powered vehicles and solar vehicles, etc. Its exhaust emissions are 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. Most of the new energy vehicles currently on sale in the Chinese market are hybrid vehicles and pure electric vehicles. According to the definition announced by the National Development and Reform Commission of the People's Republic of China, new energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels and new vehicle power devices). Advanced technologies in power control and driving form cars with advanced technical principles, new technologies, and new structures.

On March 26, 2019, the Ministry of Finance and other four ministries and commissions issued the "Notice on Further Improving the Financial Subsidy Policy for the Promotion and Application of New Energy Vehicles", which will be implemented from March 26.

New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles.

Folding Pure Electric Vehicles

Blade Electric Vehicles (BEV) are vehicles that use a single battery as the energy storage power source. , providing electric energy to the electric motor through the battery, driving the electric motor to run, thereby driving the car.

Advantages:

Relatively simple and mature, it can be charged wherever there is a power supply.

Disadvantages:

The energy stored per unit weight of the battery is too little, and because the batteries of electric vehicles are more expensive and do not form economies of scale, the purchase price is relatively expensive; as for the cost of use, Some trial results are more expensive than cars, and some results are only 1/7 to 1/3 of cars. This mainly depends on the life of the battery and local oil and electricity prices.

Folding Hybrid Electric Vehicle

Hybrid Electric Vehicle (HEV) refers to a vehicle whose drive system is composed of two or more single drive systems that can operate simultaneously. The driving power of the vehicle is provided by a single drive system alone or by multiple drive systems simultaneously according to the actual vehicle driving state. Hybrid vehicles come in many forms due to differences in components, arrangements and control strategies.

Advantages:

1. After using hybrid power, the maximum power of the internal combustion engine can be determined according to the average required power. The engine is relatively small (downsize). At this time, the fuel consumption is low, Work under optimal working conditions with less pollution. Since the internal combustion engine can continue to work and the battery can be continuously charged, its range is the same as that of an ordinary car.

2. Because of the battery, it is very convenient to recover the kinetic energy when going downhill.

3. In bustling urban areas, the internal combustion engine can be shut down and driven by the battery alone to achieve "zero" emissions.

4. The internal combustion engine can easily solve the problems encountered by pure electric vehicles such as energy-consuming air conditioning, heating, defrosting and so on.

5. You can use existing gas stations to refuel, without having to invest any more.

6. It can keep the battery in good working condition without overcharging or over-discharging, extending its service life and reducing costs.

7. Due to multiple power sources, the whole vehicle can work at the same time, and the whole vehicle has excellent power.

Disadvantages:

The system structure is relatively complex; the fuel-saving effect of long-distance and high-speed driving is not obvious.

Folding Fuel Cell Electric Vehicle

Fuel Cell Electric Vehicle (FCEV) uses hydrogen and oxygen in the air under the action of a catalyst. A vehicle driven by electricity generated by electrochemical reactions in a fuel cell as the main power source. Fuel cell electric vehicles are essentially a type of pure electric vehicle. The main difference lies in the working principle of the power battery. Generally speaking, fuel cells convert chemical energy into electrical energy through electrochemical reactions. The reducing agent required for the electrochemical reaction generally uses hydrogen, and the oxidant uses oxygen. Therefore, most of the earliest fuel cell electric vehicles developed directly use hydrogen fuel. Hydrogen storage can take the form of liquefied hydrogen, compressed hydrogen or metal hydride hydrogen storage.

Advantages:

1. Zero emission or near zero emission.

2. Reduce water pollution caused by engine oil leakage.

3. Reduce greenhouse gas emissions.

4. The conversion efficiency of the fuel cell is high (about 60%), and the vehicle's fuel economy is good.

5. Smooth operation and no noise.

Disadvantages:

Fuel cells are expensive and the cost of use (hydrogen) is also expensive.

Folding hydrogen engine car

Hydrogen engine car is a car that uses a hydrogen engine as its power source. The fuel used by general engines is diesel or gasoline, and the fuel used by hydrogen engines is gaseous hydrogen.

Hydrogen engine vehicles are a truly zero-emission vehicle that emits pure water, which has the advantages of no pollution, zero emissions, and abundant reserves.

Advantages:

The emissions are pure water and no pollutants are produced during driving.

Disadvantages:

The cost of hydrogen fuel is too high, and the storage and transportation of hydrogen fuel are very difficult according to technical conditions, because hydrogen molecules are very small and can easily penetrate the storage device. The shell escapes. In addition, the most fatal problem is that the extraction of hydrogen requires electrolysis of water or the use of natural gas, which also consumes a large amount of energy. Unless nuclear power is used for extraction, carbon dioxide emissions cannot be fundamentally reduced.

Folding supercapacitor cars

Advantages:

Short charging time, high power density, large capacity, long service life, maintenance-free, economical and environmentally friendly, etc.< /p>

Disadvantages:

The energy density is low and it is difficult to meet the needs of the entire vehicle, so it is generally used as an auxiliary accumulator; the power output attenuates as the driving mileage increases, etc.

Folding Other New Energy Vehicles

Other new energy vehicles include those using high-efficiency energy storage devices such as supercapacitors and flywheels. Currently in my country, new energy vehicles mainly refer to pure electric vehicles, extended-range electric vehicles, plug-in hybrid vehicles and fuel cell electric vehicles. Conventional hybrid vehicles are classified as energy-saving vehicles.
