"Changing overtaking" to bypass the technical bottleneck and change ideas to solve the charging problem

"The number of new energy vehicles in the world is almost 60% in China." Recently, Xu Heyi, member of the National Committee of the Chinese People's Political Consultative Conference (CPPCC) and Party Secretary of the Beijing Automotive Group, revealed in the group discussion of the All-China Federation of Trade Unions that China completed production and sales of 770,000 vehicles last year. New energy vehicles are expected to exceed 1.2 million vehicles this year.

Do not underestimate these figures, but the strategic significance is very significant. Xu Heyi said that China’s oil dependence on foreign countries is close to 70%, while auto fuel consumption consumes half of the purchased oil. Therefore, choosing a energy use program that meets China's national conditions and taking into account the needs of the people in use naturally requires the development of new energy vehicles.

Some people think that the development of the use of electrical energy will also cause pollution and become a "new disease" in urban development. Xu Heyi responded that China's electric energy structure is also changing, wind power, photovoltaic power generation and nuclear power are developing, and electric energy pollution will be less and less. Therefore, the development of new energy vehicles has great potential.

"The gap between China's fuel vehicle technology and foreign auto industry is on the internal combustion engine and gearbox. This is the soft underbelly of China's auto industry." He said frankly, from the perspective of combustion efficiency and emission indicators, developed countries have developed their technology to the extreme. It has been very difficult for China to surpass it. From a strategic point of view, China’s auto industry has chosen “change lanes and overtaking” and has set its sights on new energy vehicles, cleverly bypassing the technical bottlenecks of internal combustion engines and transmissions.

For China's new energy vehicles, he said he should have a certain degree of confidence. China started earlier, and related technologies are basically equal to the highest level in the world, and are even in the leading position in some areas.

From the perspective of consumers, Xu Heyi believes that saving money is an advantage of new energy vehicles. The cost of a pure electric car is equivalent to 1/6 of the fuel car. Among them, from the point of view of electricity consumption per hundred kilometers, the average value of pure electric vehicles is about 12 kWh, and the charging piles in Beijing are about 1 yuan per kWh, while the fuel oil per mile is about 78 liter. .

In the promotion of new energy vehicles, the current problem is still charging. “It was difficult to build charging piles in previous years. Now that the contradictions have evolved to a deeper level, it is the capacity of the district’s power system that is not enough. It is imperative to renovate old districts. It is more difficult to transform the old districts and it may become a new 'urban disease' in the future.” Xu Heyi Expressed concerns that the problem of transformation alone cannot be solved by a single company.

In fact, the prevention of new urban diseases is not in contradiction with the development of new energy vehicles. Xu Heyi disclosed a set of data. Today, the post-85s and post-90s are important new consumer groups, accounting for about half of the domestic auto market consumption. The creation of new consumer groups will also drive changes in the concept of car consumption. “For example, many young people think that they don’t need to buy a car by themselves, as long as they can use the car.” According to Xu Heyi, sharing cars will become the mainstream in the future.

In his view, sharing cars and sharing bicycles are two different things. "It's not just a stop on the road." According to reports, Beijing Automotive Group and Didi have created a new car rental model. Online car and car rental can be realized. Some people will drive the car to the front door of the house. If you bring a driver, you can rent it, or you can even achieve a joint rent. The model is very diverse.

For new energy vehicles, especially pure electric vehicles, cruising range is the most concern for consumers. "The 40% of the money spent on the battery was bought." Xu Heyi said.

"The average weight of a battery module is 400 kilograms, which is equivalent to a 'iron box' pulled down from the bottom of a car." Xu Heyi made an analogy. If a battery module is blindly added, a pure electric car that can run for 800 kilometers can be created, but this way Loss of the significance of low-carbon environmental protection. Some companies are trying to attract attention and unilaterally pursuing high mileage. However, the batteries are getting heavier and the car is carrying a lot of batteries to run and the power consumption is also higher.

A young consumer said that he bought 200 kilometers of new energy vehicles. However, after a while, he discovered that vehicles with longer cruising range appeared again. Xu Heyi responded: “The longer the cruising range is, the better, and choosing the cruising range that is suitable for you is the most economical. The money is still spent on the blade, and the battery can not be maintained.”

Solving the problem of recharging new energy vehicles, Xu Heyi seems to need to change its thinking. He talked about the "re-battery mode" of new energy vehicles. In the process of car sales, separation of vehicles and vehicles can be achieved, solving the problems of insufficient mileage and "charge difficulty". If the car power is insufficient, you can switch to a battery station for a set of batteries. Nowadays, it takes only two and a half minutes to replace a battery, and the technology is very mature, which can make up for the lack of construction of the charging pile.

Of course, with this model, the future gas station needs to be transformed into a “power station”, and enterprises in the fields of petroleum and electric power need to be involved to form a standardized service system.
