Japanese media claims that the 10% purchase tax exemption for China's new energy vehicles will be extended until 2020

In a recent development, Japanese media reported that Chinese authorities are considering extending the deadline for the new energy vehicle (NEV) purchase tax exemption, which was originally set to expire at the end of this year. This tax incentive has played a key role in making China the world’s largest market for electric and hybrid vehicles. By prolonging the policy, the government is likely aiming to further boost the growth of its domestic NEV industry. According to a report from the Fuji Industrial Business Daily on December 6th, sources indicated that the Chinese government is planning to extend the 10% purchase tax exemption for all types of new energy vehicles, including electric, hybrid, and fuel cell models, until 2020. This move signals a continued commitment to supporting the green automotive sector. China overtook the United States in 2015 to become the world's largest NEV market. In 2022, sales of new energy vehicles surged by 53% year-on-year, reaching 50.07 million units. According to data from the China Association of Automobile Manufacturers, the total number of new energy vehicles on the road has surpassed 1 million, tripling since 2015. This growing demand has also encouraged foreign automakers like Volkswagen and Ford to increase their investments in China. Tesla is reportedly exploring the possibility of building a factory in the country. Despite competition, international companies remain eager to participate in the booming Chinese NEV market. Professor Wang Yunshi, director of the China Energy and Transportation Center at the University of California, Davis, noted that the Chinese government is pushing hard to promote new energy vehicles. If targets aren't met, more aggressive policies may follow. Once the tax exemption ends, weaker domestic manufacturers could face significant challenges. To support this transition, China has been actively introducing new policies. In September, it announced research into banning the production and sale of gasoline and diesel vehicles. As the world's second-largest economy, China aims to reduce carbon dioxide emissions by 2030 and combat severe air pollution. This has led to stricter regulations on petrol and diesel vehicles, aligning with similar measures in the UK and France. Additionally, there are reports that the Chinese government is reissuing electric vehicle production licenses that were temporarily suspended in mid-2018. Once reinstated, this will open up opportunities for foreign automakers like Ford and Tesla, as well as local Chinese companies. A joint venture between Ford and Anhui Zhongtai Automobile is reportedly planning a factory capable of producing 100,000 electric vehicles annually. Foreign automakers such as Ford and Volkswagen are also developing their own EV strategies tailored to China’s strict emissions and fuel efficiency standards. Since March 2016, the Chinese government has approved 15 electric vehicle production projects. The joint venture between Vientiane Group, one of China’s top auto parts manufacturers, and a public entity has already received approval. With relaxed oversight, the traditionally state-dominated auto industry is expected to see increased competition. Some companies from sectors like smart TVs and air conditioners have already entered the automotive market, signaling a broader shift toward innovation and diversification in the industry.

Amplifier Board

Digital Amplifier Module​
The Digital Amplifier Module is a crucial component in the field of audio, delivering exceptional audio amplification for various audio devices. Leveraging digital signal processing technology, it enables precise manipulation of audio signals, achieving performance enhancements that are difficult to match with traditional analog Power Amplifiers.​
Working Principle​
The operation of the Digital Amplifier Module is highly sophisticated. First, upon receiving an analog audio signal, the module rapidly converts it into a digital signal through an Analog-to-Digital Converter (ADC). These digital signals then undergo a series of meticulous processes in the Digital Signal Processor (DSP), such as filtering, equalization, and reverb, to optimize the sound quality. Subsequently, the processed digital signals are converted back into analog signals by a Digital-to-Analog Converter (DAC), and finally, power-amplified by the output stage amplifier to drive the speaker to produce sound. For instance, in a common Class-D amplifier, the power output transistors operate in a switching state, controlling the power output by adjusting the duty cycle of a fixed-frequency rectangular pulse, which significantly improves efficiency.​
Product Advantages​
.High Efficiency and Energy Conservation:Compared with traditional analog power amplifiers, digital amplifier modules are extremely efficient, generally reaching over 90%. Take a certain digital power amplifier module as an example; when outputting the same power, its energy consumption is only about half that of a traditional analog power amplifier, greatly reducing energy consumption. This makes it especially suitable for devices with strict power consumption requirements.​
.High-Fidelity Sound Quality:With advanced digital signal processing technology, it can precisely process audio signals, effectively reducing signal distortion and restoring the original details of the audio, thus providing a high-fidelity auditory experience. In professional music recording and playback equipment, digital amplifier modules can accurately reproduce every note of the music, making the audience feel as if they were at the live performance.​
.Compact Size and Lightweight:Thanks to the digital design and highly integrated chip technology, digital amplifier modules have been significantly reduced in size and weight. This feature has led to their extensive application in portable audio devices, such as Bluetooth speakers and headphone amplifiers, making them convenient for users to carry.​
Application Scenarios​
.Home Audio Systems:It can be used to build home theaters and Hi-Fi audio systems, providing users with an immersive music and movie sound experience. Whether enjoying the thrilling sound effects of a blockbuster movie or listening to beautiful music, digital amplifier modules can deliver excellent audio performance.​
.Car Audio:In the limited interior space of a car, where high power is required, digital amplifier modules can effectively enhance the sound quality of car audio systems with their high efficiency and compact size, creating a high-quality auditory environment for drivers and passengers.​
.Professional Audio Fields:In places like recording studios and performance stages, where extremely high requirements are placed on the sound quality and stability of audio equipment, the high-fidelity and reliability of digital amplifier modules make them an ideal choice for professional audio devices, meeting the stringent audio quality standards of professionals.​
In conclusion, with its unique advantages, the Digital Amplifier Module plays a vital role in the audio field, offering high-quality audio amplification solutions for audio enthusiasts and professionals alike, and continuously driving the development and innovation of audio technology.
