During the Shanghai Auto Show this year, Chinese car companies launched a number of new energy vehicles in a concentrated manner, and they gradually launched the market later. Subsequently, the “Regulations on the Management of New Energy Vehicle Manufacturers and Product Access Management†promulgated by the Ministry of Industry and Information Technology referred the new energy vehicles to the heights of the world’s attention. It seems that the attempt to “resources for new energy vehicles to the country†was clarified. .
However, the upsurge of electric vehicles in the automotive industry, which is a matter of fact, has caused people to doubt its authenticity. Among the many new energy vehicles that are listed this year, electric vehicles (EVs) and hybrid vehicles (HEVs) account for a large proportion. Domestic hybrids have a certain distance from Toyota Prius and Honda Civic hybrids because of battery and motor technology.
According to statistics from related departments, in 2008, 899 new energy passenger vehicles were sold, an increase of 117% year-on-year; and new energy vehicles of commercial vehicles sold a total of 1,536 units, a year-on-year decrease of 17%. Among them, commercial vehicles are mainly city buses, and the main buyers are government institutions. This year, when manufacturers push new energy vehicles, they also tend to “bundle†with local policies. Considerable evidence shows that in addition to the state support behavior represented by the Ministry of Industry and Information Technology, more new energy vehicle companies “gambling†on the financial resources of local governments.
The automobile industry revitalization policy mentioned the need to “renovate the existing production capacity and form a new energy vehicle production capacity of 500,000 pure electric vehicles, rechargeable hybrid vehicles, and ordinary hybrid vehiclesâ€, which shows the attitude of the Chinese government on new energy automobile projects. It is serious and pragmatic. Because China's current mainstream vehicle capacity has exceeded 15 million by 2010. In fact, under the impetus of some local governments, many companies’ new energy vehicle projects are separate projects to re-establish factories. At the same time, in terms of new energy vehicles currently on the market, some models are not suitable for promotion across the country. The reality is that LPGs that use gas as their energy source are mostly concentrated in cities with rich oil and gas resources, and their regional features of consumption are obvious. Because of the lag in related facilities for pure electric vehicles, even if they are sold, they are mostly symbolic devices that are not yet practical. In the hybrid models sold last year, the Toyota Prius had an absolute advantage.
There is no free lunch under the sun. It is hard to believe that Toyota, Honda, GM, Mercedes-Benz, BMW and other vehicles will bring the latest new energy vehicles to China just to make profits. The support of the government is not unlimited. We hope that our car companies will lay down the psychological dependence and invest the relevant costs in the field of technology research and development. We will ensure that the pragmatic attitude of using traditional energy as the basis for joint efforts in key technology fields will make it more accessible. The cost of more new energy vehicles will be reduced. After all, consumers spend their money on their own cars.
The current utility of environmental protection technology and representative models
LPI Hybrid Technology Representative Model: Hyundai Elantra Yuet LPI
At the beginning of this year, the modern "Blue Drive" brand LOGO made its world debut at the Geneva Motor Show. The i30 blue was the first car to use the Blue Drive, and it also made its world debut at the Geneva Motor Show. This summer, Hyundai Motor will push Blue Drive to a new stage - the first modern hybrid car will continue to be sold in South Korea. Elantra LPI, also known as Domestic Evonik, is the world's first LPG (liquefied petroleum gas) fueled hybrid vehicle using lithium ion polymer batteries (LIPB). According to industry insiders, this model is expected to be introduced into China and become the first new technology model of the modern Kia Group in China.
The "Elantra LPI Hybrid" debuted at the Seoul Motor Show in April is Korea's first mass-produced hybrid vehicle fueled by pollution-free fuel LPG. While ensuring environmental protection and economical efficiency, it is different from the existing Elantra in terms of its design and convenient functions, and it has improved its merchandise.
From June 15th, Hyundai Motor’s South Korean business outlets began receiving advance bookings for cars and officially launched marketing and promotional activities. Relevant persons said: "The Elantra LPI hybrid vehicle is based on the environmentally friendly raw material LPG as the main fuel, and the overseas hybrid vehicle based on gasoline is the main fuel. It is worth mentioning that the price of LPG is only 1/2 of the price of gasoline. Compared with gasoline, it has a price advantage and can compete with imported hybrid vehicles."
The Elantra LPI Hybrid is equipped with a 1600cc gamma LPI HEV engine and a CVT gearbox, achieving a fuel efficiency of 17.8km/L. At the same time, the Elantra LPI hybrid vehicle is lighter than existing alkaline nickel-hydrogen models, and it has used lithium polymer batteries for the first time in the world.
The four core electric components mounted on the Elantra LPI Hybrid are: an electric motor with auxiliary driving force, a battery for storing electric energy, an inverter for transferring high voltage from the battery to the driving motor, and converting the high voltage of the battery into audio and 12V DC power converter in headlights. Hyundai Motor has completed the independent development and localization of the above components.
On July 22nd, Hyundai-Kia Group announced that on July 22, the company announced that it will invest a total of 4.1 trillion won in the eco-friendly car field to meet the requirements of further strengthening environmental protection and fuel efficiency regulations at home and abroad. After the hybrid vehicles of Elantra and Freddy, the Hyundai Group intends to expand hybrid power to mid-size vehicles next year. The annual scale will gradually reach 30,000 vehicles, including vehicles exported to the United States.
Hydrogen fuel cell vehicles that were developed on the premise of commercialization in 2012 have now been expanded to 100 vehicles in and outside South Korea. The company intends to effectively promote the commercialization of eco-friendly cars.
Plug-in hybrid technology representative model: Chevrolet VOLT
Chevrolet Volt has created a new vehicle series. It is an Extended-Range Electric Vehicle, or simply E-REV, a remote electric vehicle.
The Chevrolet VOLT can use electric power to control the wheels at any speed, anytime, anywhere. It can travel for 40 miles under electric energy and it stores electricity through a 16KWH lithium battery. When the electricity in the battery consumes light, gasoline or an E85-type engine will start to act as a generator to charge the battery. This way, VOLT's sustainable mileage can be hundreds of miles. Until the car arrives at the next charging location. Different from traditional battery-powered vehicles, VOLT effectively reduces people's concern about "distance traveled", and people do not have to panic when the battery runs out, and maintain a confident attitude.
The Chevrolet VOLT can be used either for 120-volt or 240-volt power in the home. The car’s smart charging technology ensures that it takes less than 3 hours if the external voltage is 240 volts. At present, the United States charges 10 cents per kilowatt hour, and the daily expenses are generally around 80 cents, because it is generally possible to drive 64 kilometers on a single charge. GM believes that the cost of its use is very low, and charging a single charge is not as good as a cup of coffee. And if you charge once a day, you may not be able to spend as much as your home refrigerator for one year.
Complete electric drive technology representative model: Tiida Electric Vehicle
Benefiting from the government's industrial support for new energy vehicles, Nissan and the government have set up pilots in Wuhan and will launch electric vehicle plans next year.
Recently, the prototype of an electric vehicle based on Tiida's body debuted at Nissan Motor Co.'s 2009 Nissan Advanced Technology Briefing. The new car is planned to be listed in the United States and Japan in 2010.
Nissan Motor Co., Ltd., which is equipped with a pure electric vehicle, has independently developed a motor with a maximum output of 80 kilowatts and a maximum torque of 280 nanometers. The response is rapid and the acceleration performance is good. With Nissan's unique motor control system, the acceleration process of electric vehicles is more smooth and truly realized.
Acceleration of electric cars seamlessly.
The compact stackable Li-ion battery with a capacity of 24 kilowatts is installed under the body without occupying any cab or luggage space, making the use of vehicle space more economical. At the same time, with the regenerative braking system to charge the battery during deceleration and braking, the maximum cruise mileage of the vehicle can exceed 160 kilometers.
The bracket specially installed for the battery pack greatly improves the body rigidity of the electric vehicle and improves the durability. The combination of a highly rigid platform and an electric powertrain minimizes vehicle vibration and external noise, creating a quiet and enjoyable driving experience for drivers and passengers.
