China imitates the United States to formulate electric vehicle points, the system of virtue, the technical advantage is not guaranteed

German media said that on the occasion of the German economic minister Gabriel's visit to Beijing, a new draft shows that China is formulating an electric vehicle points system.

According to the report of the German Voice Radio website on November 1, the Beijing government hopes that more electric vehicles will be put on the streets and the domestic car enterprises will become the technological pioneers of the electric vehicle market. To this end, China is planning to introduce a point system. According to the "Süddeutsche Zeitung" report, automakers must score points in the future, that is, sell the prescribed proportion of electric vehicles. The Ministry of Industry and Information Technology of China has been brewing the draft for several months.

The report said that the Beijing government clearly plans to significantly increase the sales of electric vehicles. In 2018, automakers must sell EVs to 8% of total sales, 10% in 2019, and 12% in 2020. The Süddeutsche Zeitung newspaper writes that if manufacturers fail to meet this requirement, they must either reduce production or buy points from other car manufacturers in a way similar to buying emissions rights in the energy sector.


DPA reported that the new draft requires manufacturers to apply for a license, not only in China, but also in China. The Chinese joint venture partners indispensable to foreign automakers must prove that they fully master the electric vehicle technology, that is to say, German companies must hand over all their technology. DPA quoted an industry insider as saying, "If the draft is passed, it will lead to compulsory and complete technology transfer."

According to the report, for this year, Beijing clearly cannot achieve the goal of doubling the number of electric or hybrid vehicles. A representative of the China Association of Automobile Manufacturers told the Shanghai Securities News that the goal of getting 700,000 electric or hybrid vehicles on the road is almost impossible to achieve this year.

The just-released draft has given German automakers pressure to double. In view of the poor air pollution situation in China's big cities, Beijing's desire to increase the number of electric vehicles is reasonable.

At the same time, however, industry insiders pointed out that the draft also means competition distortions and subsidies to the domestic auto industry. If foreign automakers fail to meet the required share of electric vehicles, they may have to buy points from Chinese producers, which is to subsidize their competitors in disguise.

The German ambassador to China, Ke Muxian, wrote to the Ministry of Industry and Information Technology four months ago to request an explanation. According to the news of DPA and the SÃœD, the letter has not yet been answered. The news from the German government circle said, "The move is based on industrial policy considerations."

According to the report, automakers estimate that the possible calculation method is to sell 4 points for an electric vehicle and 2 points for a hybrid vehicle. Cui Dongshu, secretary-general of the China National Passenger Car Market Information Association, has a similar view: “For example, Volkswagen sold 3 million vehicles in China in 2018 and now, so there must be 60,000 electric vehicles.” If it is pure electric For a 50-kilometer hybrid car, it will cost 120,000.

A similar credit system has been implemented in California, USA. This gave Tesla, the US automaker, a small profit for the first time in three years. Of these, 139 million are from the sale of so-called zero-emission vehicle points. Buying points allows California's automakers to refrain from fulfilling their obligation to produce electric vehicles. Tesla, which only produces electric cars, can sell points. Industry insiders estimate that the company has now sold points equal to the amount in 2014.

Ultrasonic Sensor

Yuhai Company is engaged to research and development of piezoelectric products and related piezoelectric products, the related piezoelectric products includes the piezo sensors and transducer.


The ultrasonic transducer is a kind of transducer that converts the ultrasonic signal into electric signal, or vice versa. Ultrasound transmitter and receiver is a transducer that can transmit and receive ultrasound. Ultrasound sensor is a kind of sensor, in essence, it is also a transmitter and receiver. The working principle of this kind of equipment is similar to that of radar and sonar. Active ultrasonic sensors can emit and receive reflected waves, and determine the distance of the target by measuring the time interval between transmission and reception. Passive ultrasonic sensor is actually a microphone that can convert ultrasonic signal into electrical signal.

According to the working principle and materials used, the ultrasonic transducer has piezoelectric transducer, electrostatic transducer (capacitive transducer), magnetostrictive transducer, electromagnetic acoustic transducer, mechanical transducer and other types [1].
