New energy vehicle
Type and characteristics of new energy vehicles
1，New energy car characteristics
Pure electric cars are powered by a car rechargeable battery or other energy storage device, driven by a motor. The technology is relatively simple, as long as the power supply is met, but his power storage amount is too low, and the urban charging facility and high-speed road charging place still cannot be fully covered, and the battery replacement and maintenance value higher.
These conditions have restricted the development of early new energy vehicles.
2，Types of new energy vehicles
1.2 Hybrid vehicles, hybrid vehicles refer to those models that use traditional fuels while equipped with engine and electric motors to improve low-speed power output and fuel consumption.According to the different types of fuel, it can be divided into two types of car hybrid and diesel mixing. It compared to traditional cars, hybrid car fuel consumption and less pollution.
1.3 Fuel batteries, fuel cell vehicles are fuel with hydrogen, methanol, etc., generate current by chemical reaction, relying on motor driven, which is a green environmental protection car.
At the same time, it can reduce the water pollution caused by oil leakage, reducing the emissions of greenhouse gases, and the energy conversion efficiency of the fuel cell is much higher than the internal combustion engine.
1.4 hydrogen power cars. Hydrogen does not contain carbon, and does not increase the greenhouse gas in the atmosphere after combustion, and can pass solar energy.The renewable energy such as wind energy can be, so it is considered to be ultimate energy.
However, the fuel cost is too high, and the storage and transport of hydrogen fuel is very difficult in accordance with technical conditions, since the hydrogen molecules are very small, they will escape through the housing of the storage device.
The development status of new energy vehicles
In the past two years, China's auto makers have begun to focus and apply P2 mixed technology. P2 hybrid modules are a complete, independent module, including motors, clutches, and actuators. The module can achieve a variety of drive modes, including pure electric drives, and travel, pure engine drive travel, and the like. Pure electric technology has also achieved great progress, and the level of vehicle technology is also close to some of the international products. From a general trend, a new integrated electric chassis, lightweight material. Intelligent technology will be widely used in the next generation of new energy models. In recent years, the power supply capacity has been steadily improved, and the domestic process of key materials is accelerating. From the performance, china's lithium battery has reached 150WH / kg, from a cost, the price of battery raw materials has declined over all.
The development prospect of new energy vehicles
New energy vehicles are a rare opportunity for China's cross-development, and the new energy automobile industry carries the historical mission of china's car industrial corner overtaking. Whether it is a government or industry, it is very important to the development of the industry. The government has a considerable policy to support it's development. At the same time, domestic new energy automobile companies increase research and development, and focus on solving the core technology of new energy vehicles, and comprehensively enhance the quality of new energy vehicles. Many domestic automobile companies have achieved a lot.
chinese's government departments focus on the cancellation of the signal of traditional fuel cars production and sales schedule. This will develop new energy auto industries is a major good news, which will promote the rapid development of new energy automotive industries.
