SAIC Group will open up the market for hydrogen fuel cell vehicles
The grinder is a machine tool that uses abrasive tools to grind the surface of the workpiece. Most of the grinders use high-speed rotating grinding wheels for grinding processing, while a few use other abrasive tools such as oilstone, abrasive belts and free abrasives for processing. With the increase in the number of high-precision and high-hardness mechanical parts, as well as the development of precision casting and precision forging processes, the performance, variety and output of grinders are constantly improving and growing, so HOSTON grinding machine can provide you with grinding solutions in various fields.

The news that Toyota's hydrogen fuel cell vehicles will be mass-produced two years later has caused the industry's controversy over the existing technology options for new energy vehicles. In fact, fuel cell vehicles, a seemingly science-fiction-inspired product, had SAC's fuel cell vehicles already equipped with sufficient marketability in terms of technological advancement, safety, and durability as early as SAIC's plans. Keeping up with technological trends and even developing forward-looking technologies by itself is the goal of SAIC's new energy vehicle development.
General Manager of SAIC's New Energy and Technology Management Department told reporters that SAIC has been investing in new energy since 2005 and has tried different technical routes. In 2009, it identified the overall technology path, three technical routes and product plans. “We have been developing this technology road for the past five years, that is, the development of hybrid vehicles and electric vehicles in the short term and the development of fuel cell vehicles in the medium and long term. The new energy vehicles produced under this technological path have been tested by the Expo and also for us. Follow-up R&D provides valuable experience."
According to reports, at the 2010 World Expo, the new energy vehicles in the entire park were basically provided by SAIC Motor. “To tell the truth, our industrial foundation was very weak at that time. To assist the Expo was a great test for us. It is gratifying that we successfully completed this task.†Introduction of the dry frequency, during the World Expo, SAIC Motor provided 1,000 new energy vehicles, carrying 120 million passengers and a total mileage of more than 29 million kilometers.
He said: "Security is the focus of our attention. At that time we learned from the experience of the Beijing Olympic Games and supplied a new type of energy-conversion bus. Shanghai's summer is hot weather, electric cars are very afraid of leakage, we have done experiments, will be electric The battery pack of the car is placed in a pool of goldfish and tested in the 'Faraday cage'. In addition, there is a fire experiment. The battery is put on fire and burned after more than 40 minutes. It will not happen. explosion."
In terms of frequency, these three technical routes are actually equally important. From the perspective of industrialization, each technological approach has its advantages and problems. The advantage of an electric vehicle is zero emissions during driving, but it has a relatively short driving range, high infrastructure dependence, and low environmental protection in China's coal-fired power generation environment. The advantages of plug-in hybrid vehicles are just to make up for the shortcomings of electric vehicles, but its cost will be higher because it has two sets of power guarantee (electric drive and fuel drive).
General said that SAIC's electric cars are started from small cars. They use less batteries and are lighter in weight. The carbon dioxide emissions per kilometer are about 75g, which is about half that of conventional cars. For example, the Roewe E50 pure electric vehicle is truly energy-efficient in China. The dry frequency admits that although the acceleration of the car is not very good, the acceleration of the car is very good. "As a pure electric trolley used in the city, I feel that the former is more important than the acceleration of 0 to 50 kilometers and the acceleration of 0 to 100 kilometers."
In addition, the Roewe 550 plug-in hybrid vehicle has begun to accept market reservations, driving only 58 kilometers under pure electric power. As a strong hybrid vehicle, fuel consumption is only about half that of a conventional car.
He said: "For fuel cell vehicles, the industry has different views, but in the past two years, this model has been active in Europe and the United States market. At home, the government issued a target of energy-saving emission reduction limits that by 2015 The fuel consumption of energy-saving passenger vehicles is less than 5.9 liters/hundred kilometers; it is less than 4.5 liters/hundred kilometers by 2020. This is a major driving force for SAIC's investment in fuel cell vehicles."
According to the introduction of dry frequency, the technical path adopted by SAIC is a plug-in fuel cell, which is combined with an electric vehicle. “We are different from Toyota and GM. SAIC's fuel cell stack is equipped with a large electric drive engine. We have considered that if we want to accelerate, we need to use the fuel cell with full load and full power consumption. This kind of power is very large. It will be very high and the lifespan will be reduced. Our plug-in fuel cell vehicles can guarantee a lower cost, which is a suitable path for our own development."
At present, SAIC's fuel cell vehicles use 350 kg of hydrogen bottles and the driving range is about 250 kilometers. The next-generation models will use 700 kg of hydrogen bottles and the driving range can reach 300 to 400 kilometers.
"We will not follow Tesla, follow Toyota, GM to do new energy vehicles, we will combine their expertise, and China's environment, to create the most suitable product for the market." Dry frequency said.
