The transportation sector now accounts for about 1/4 of the world's carbon dioxide emissions. In 2020, the global transportation carbon dioxide emissions amounted to 72 billion tons, because COVID-19, which was nearly 85 billion tons in 2019, dropped by 10%. The development of new energy vehicles is the main direction of decarbonization in the transportation field for the world.
According to the prediction of the International Energy Agency (IEA), according to the net zero emission scenario of the transportation sector by 2050, the CO2 emissions related to transportation will need to be reduced by 20% to 5.7 billion tons by 2030.
For China, developing and strengthening the layout of new energy vehicle industry is of great significance to decarbonize and reduce environmental pollution!
Over the past decade, Chinese enterprises have made every effort to layout new energy vehicles dominated by electric vehicles, and government policies have also strongly supported them. Especially in the past two years, new energy vehicles have ushered in a blowout development.
The new energy vehicle industry development plan (2021-2035) issued by the State Council not long ago raised the development of new energy vehicles to a national strategic height. The plan proposes that by 2025, the average power consumption of new pure electric passenger vehicles in China will be reduced to 12.0 kwh / 100 km, and the sales of new energy vehicles will reach about 20% of the total sales of new vehicles.
This goal will undoubtedly once again promote the outbreak of new energy vehicles in China and drive the upstream and downstream markets of the industrial chain - Basic charging equipment - charging pile!
The construction of charging pile is the basic support for the development of new energy vehicle industry. However, the charging pile cannot intuitively and intelligently inform consumers of the current working state and technical problems of the charging pile. Therefore, in order to solve the above problems, many manufacturers add voice prompt function to the charging pile. The intelligent charging pile with voice prompt function can voice remind users how to use and guide users to use!
A product equipment with a good voice prompt chip is far competent for human labor. Therefore, in many products that need voice prompts such as guidance, prompt and alarm, adding a high-quality n9305 voice prompt chip is conducive to cost saving and flexible use.
As the necessary basic equipment for public buildings, shopping malls, public parking lots and residential parking lots in the future, in the subsequent application process, after adding n9305 voice chip, the charging pile can first deal with the troubles caused by people's use of charging pile, guide people to operate the equipment step by step, throw away the paper instructions and guides, make the day more environmentally friendly and human resources more efficient.
The n9305 voice chip is an MP3 chip that provides serial port, supports the computer to directly update the content of SPI flash, and supports FAT16 and FAT32 file systems.
You can play the specified music and how to play music through simple UART serial port instruction or first-line serial port instruction. Its most important feature is to support cloud update and remote update of voice content. There is no need for enterprises to send people to the site to use USB to replace voice content. Voice content can be directly replaced in the background networking, saving human resources for enterprises!
Moreover, the brand advertisement can be inserted when the user uses the charging pile, which is conducive to the promotion of the brand; Such as "less pollution, more blue sky and white clouds, thank you for using XX brand charging pile!" In addition to promoting the concept of environmental protection, it can also make people remember the brand of this charging pile more deeply.
Application scheme of n9305 voice chip on charging pile (voice content can be customized):
1. Welcome to XXX brand charging pile, less pollution, more blue sky and white clouds!
2. Please select app login or scan code to login VX applet;
3. Please select the charging type (DC, AC)
4. Please do not unplug when charging;
5. The power is fully charged and the power supply is disconnected. Please pay attention to driving safety;
6. The power supply is not grounded and has entered emergency mode. Please contact the administrator immediately!
……
The development process of new energy vehicles has further accelerated after China put forward the development goals of "carbon peak" and "carbon neutralization", and how to meet new challenges and seize new opportunities for charging infrastructure will become a new theme. As an important part of charging pile, charging module, voice chip and smart UHV power grid will also help the vigorous development of charging pile industry in its in-depth development.
