In 2018, the year has officially begun. With the ongoing transformation of artificial intelligence and the Internet of Things, the economic scale continues to grow, and innovative business models are emerging rapidly. Artificial intelligence is driving a new wave of industrial evolution, while China's Internet of Things sector has entered a high-speed development phase, setting the stage for a new chapter in 2018.
The Chinese internet continues to write a new chapter.
In Paris, France, shared bicycles have become a common sight.
Throughout 2017, the Chinese internet was full of momentum, with frequent news reports highlighting its rapid development. High-speed rail, Alipay, shared bicycles, and online shopping have become known as the "new four great inventions" of China in the eyes of foreigners. Artificial intelligence, the Internet of Things, big data, and virtual reality are increasingly merging with the real economy, giving rise to booming new industries and offering traditional sectors new opportunities for transformation. Experts were invited to discuss these hot topics and look ahead to what the Chinese internet might bring in 2018. There's every reason to believe that 2018 will be another milestone year, where the Chinese internet continues to shine brightly.
The sharing economy is leading the global trend.
Unbeknownst to many, the sharing economy has become an essential part of daily life in China—whether it's shared travel, charging stations, or shared housing. Notably, shared bicycle services originated in China and represent a true "Chinese innovation." From design to manufacturing, it exemplifies "China's creation" and "China's wisdom."
Li Yongjian, Director of the Internet Economics Research Office at the Institute of Finance and Economics, Chinese Academy of Social Sciences, stated that the sharing economy in China is growing at a fast pace. The economic scale keeps expanding, and numerous innovative business models are emerging. In the transportation sector, participation in the sharing economy is rising, with shared bicycles seeing the fastest user growth. The accommodation-sharing market also experienced rapid development, with the transaction volume expected to reach 12.52 billion yuan in 2017—an increase of 42.6% compared to 2016. Meanwhile, shared cars are entering a period of accelerated growth, with platforms like EVCARD appearing in cities such as Beijing, Shanghai, Guangzhou, and Chongqing. By September 2017, Shijingshan District in Beijing proposed establishing the city’s first shared vehicle demonstration area.
Li added, “China's sharing economy has expanded overseas, absorbing international influences while building on foreign business models. Since 2015, companies like ofo, Mobike, and others have launched their operations globally. On June 13, 2017, Mobike announced its presence in its 100th city—Manchester, UK. Ofo has entered 20 countries and over 250 cities. Di has accelerated its international expansion, investing in platforms such as Brazil's 99, India's Ola, South Africa's Taxify, Singapore's Grab, U.S.-based Uber and Lifu, and Careem in the Middle East and North Africa. Its cooperation network now covers more than 1,000 cities across North America, Southeast Asia, South Asia, and South America, reaching 60% of the world's population. Shared bicycles have become a symbol of China's innovation.â€
As the digital era continues to evolve, the Chinese internet is not only shaping the domestic landscape but also making a global impact. With the rise of AI, IoT, and the sharing economy, 2018 promises to be a year of continued innovation, growth, and transformation.
Battery Energy Storage System
Battery Energy Storage System (BESS) is a complex system that integrates multiple technologies and devices to store electrical energy in the form of chemical energy and release it for use when needed. The following is a detailed description of the purpose of the BESS class:
I. Basic definition
BESS is a system that uses lithium batteries, lead batteries, etc., as energy storage carriers to store electricity for a certain period of time and supply electricity when needed. The power provided by the system has functions such as smooth transition, peak cutting and valley filling, frequency regulating and voltage regulating, etc. It is of great significance to improve the stability, reliability and flexibility of the power grid.
Second, system composition
BESS mainly consists of the following parts:
Battery Array:
It is the core part of BESS and is used to store electrical energy. Common energy storage batteries include lithium-ion batteries, lead-acid batteries and so on.
The performance of the battery directly affects the efficiency and reliability of the entire energy storage system.
Battery Management System (BMS) :
Responsible for intelligent management and maintenance of each battery unit, prevent the battery from overcharging and overdischarging, and extend the service life of the battery.
Monitor the battery status, including voltage, current, temperature and other parameters, to ensure the safe operation of the battery pack.
Energy Storage converters (PCS) :
It is one of the key devices in BESS, responsible for converting direct current in the battery pack to alternating current, or alternating current to direct current, to meet the needs of different application scenarios.
PCS has the ability to control the flow of electric energy bidirectional, and can flexibly adjust the power and voltage of the grid.
Local controller:
Responsible for local control and management of BESS, including data collection, condition monitoring, fault diagnosis and other functions.
The local controller can also communicate with the external energy management system (EMS) to receive instructions and perform energy scheduling and power control.
Power distribution system:
Devices such as switches, circuit breakers, cables, etc. are included to connect BESS to the power grid or other loads.
Distribution systems need to ensure the safe transmission and distribution of electrical energy.
Auxiliary equipment:
Including temperature control system, fire protection system, lighting system, monitoring system and so on.
These devices are used to ensure the safe operation and routine maintenance of BESS.
3. Technical characteristics
High efficiency:
BESS has high energy conversion efficiency and charge and discharge efficiency, which can maximize the use of stored electrical energy.
Flexibility:
BESS can be flexibly configured and expanded according to actual requirements to adapt to different scales and scenarios.
Reliability:
With advanced BMS and PCS technology, BESS is able to ensure the safe operation and efficient utilization of battery packs and improve the reliability of the system.
Environmental protection:
BESS uses renewable energy for energy storage and power supply, reducing dependence on traditional energy sources and environmental pollution.
