The Beijing 2022 Winter Olympics, which has attracted much attention at home and abroad, is about to enter the opening countdown. Zhangjiakou, one of the winter Olympic areas, is also fully prepared for this.
At the beginning of February 2021, the first "Meet in Beijing" series of winter sports test activities of the Beijing Winter Olympics was successfully held in Yanqing And Zhangjiakou. At that time, this also brought major benefits to the ring Beijing area represented by Zhangjiakou. According to public statistics, with the help of the Winter Olympic boom, the total scale of China's ice and snow industry is expected to reach 1 trillion yuan in 2025.
Many local companies are helping to prepare for the 2022 Winter Olympics. As a huanjing enterprise, Rongsheng is also involved as the host.
Specifically, Rong Wanjia, a property company owned by Rongsheng, supported the test match of the Zhangjiakou venue of the Beijing Winter Olympics, responsible for the cleaning of the venue and the cleaning of waste. At the same time, Rongsheng Mengguli, a high-tech enterprise under Rongsheng, also actively participated in the research of the "Key Technologies and Industrialization Applications of High-performance All-Climate Electric Bus Power Platform" to prepare for the Winter Olympics.
Recently, the project won the first prize of the 2021 "China Automotive Industry Science and Technology Award" Science and Technology Progress Award. More critically, the all-climate battery will be used in the Winter Olympic buses to serve venues and athletes.

01 Winter Olympics
Rongsheng's association with the Winter Olympics this time began half a year ago.
In August 2021, Rongmiao City Property, a subsidiary of Rongwanjia, successfully won the bid for the venue property service of the Zhangjiakou Competition Area of the Beijing Winter Olympics. For Rongwanjia, this is a major breakthrough in the field of social public services and can embark on the international stage.
From February 16 to 26, 2021, the first "Meet in Beijing" series of winter sports test activities for the Beijing Winter Olympics was held in Yanqing and Zhangjiakou. A month before that, Rong Wanjia had signed up for the Zhangjiakou Venue Test Match Support Event at the Beijing Winter Olympics.
According to Rong Wanjia's sharing, after receiving the property service demand of the Chongli Winter Olympics in Zhangjiakou, Rong Wanjia rushed to the field for the first time. After the inspection, the company quickly organized the dispatch of nearly 100 employees of Langfang, Handan and Cangzhou companies in Hebei to go to the work site of the Chongli Winter Olympic Games to clean the Winter Olympics and clean the waste.
Since then, daily cleaning, snow removal, septic tank cleaning, venue killing, garbage classification and transportation, etc., the National Cross-Country Ski Center, the National Ski Jumping Center, the National Biathlon Ski Center and other venues where the Beijing Winter Olympics are held, are all over the Rongwan family. At this point, Rong Wanjia has completed all the support work in the early stage of the Beijing Winter Olympic Games.
"Faster, higher, stronger", in the environment of minus 20 degrees, nearly 100 property owners from Rongwanjia Zhangjiakou, Handan, Cangzhou and Langfang companies personally interpreted this Olympic motto in this rescue battle. With Rongwanjia ringing the bell and listing, providing property services for the Beijing Winter Olympics, it means that Rongwanjia has completed another leap-forward exploration in the field of non-residential property services on the road to "faster, higher and stronger".
At present, various property companies are working hard to expand third-party property projects to expand the property management area, including Rongwanjia. At the same time, in order to achieve diversification, property management companies are also developing non-residential property projects. For Rongwanjia, providing property services for the Beijing Winter Olympics project allows Rongwanjia to have more experience and endorsement to develop third-party and non-residential properties to achieve diversified development.
This is a milestone for Rongwanjia. By leveraging the Zhangjiakou Olympic Sports Construction Joint Venture and enhancing market influence, Rongwanjia urgently needs to detonate a new round of value.
02 Layout of science and technology track, Rongsheng Alliance Guli handed over a new answer sheet
As a comprehensive enterprise, in addition to the rongsheng development of the main real estate track, Rongsheng has also made frequent efforts in the science and technology track in recent years, exploring multiple industries such as new energy batteries and automobiles, which are mainly carried by rongsheng mengguli and other enterprises.
During this Winter Olympics, Rongsheng Mengguli handed over a brilliant answer sheet.
In cold weather conditions, making batteries better energy efficient is actually a complex proposition.

The concept of the "Green Olympics" also forced the organizing committee to put into use a new energy electric vehicle that is cold enough to operate normally in an average -20 °C environment. In February 2017, Rongsheng Alliance Guli set up a research and development team and signed a cooperative development agreement with EC Power in the United States, announcing that it will jointly develop an all-climate battery system for electric vehicles for the environmental application of the Winter Olympic Games with the team of academician Sun Fengchun of Beijing Institute of Technology.
At low temperatures, power batteries are prone to performance degradation, reduced charging and discharging efficiency, and large polarization of working voltage, which leads to problems such as slow charging and short endurance of electric vehicles in low temperature conditions in winter. The all-climate battery technology has continuously improved its performance at low temperatures through continuous testing and testing.
Among them, the heating technology of the all-weather battery has been improved from 3 °C/min in 2017 to 7 °C/min in 2019, which makes the battery heated from -20 °C to 0 °C in less than 3 minutes, and the energy retention can be achieved at -25 °C after the battery is heated, and the vehicle's mileage has increased by 20%-30%, and it can be charged in 1 hour. And such performance has belonged to the world's leading level.
Such performance has also attracted the attention of a number of top car companies, including FAW Hongqi, BAIC, GAC, Foton Motor, Yutong Automobile and many other well-known car companies have established cooperative relations with Rongsheng Mengguli on this technology, at the same time, Daimler and Volkswagen and other international car manufacturers have cooperated and communicated with Rongsheng Mengguli on this technology, in addition, in the military field, the technology has been partially applied.
This technology was also tested by the Winter Olympics in early 2020. On January 19, 2020, Rongsheng Mengguli's new generation of all-climate power battery was tested and verified for -30 °C severe cold environment reliability. Rongsheng Mengguli's new generation of all-climate power battery system is equipped with a total of five models of Beiqi Foton pure electric bus, fuel cell bus and BAIC N60 pure electric passenger car, ready to meet the test of the Winter Olympic environment. In the environment of -30 °C, Rongsheng Mengguli successfully passed the test with the performance of the battery self-heating temperature rise rate of 7 °C/min.
Wu Ningning, deputy general manager of Rongsheng Mengguli, introduced that at present, the energy density of Rongsheng Mengguli all-climate battery system exceeds 159Wh/kg, which can operate normally at an ultra-wide ambient temperature of -40 °C-60 °C, and the self-heating speed of the battery reaches 7 °C/min at ultra-low ambient temperature, and the power consumption per 10 °C per liter of temperature is only 1.5% of the rated power, and the vehicle can be charged for 1 hour in a -40 °C environment after heating (SOC from 30% to 100%).
Feng Quanyu, chairman and general manager of Rongsheng Mengguli, said that the all-climate battery system developed by RongshengMeng Guli has completely solved the technical problems of slow charging, insufficient charging and poor performance of electric vehicles at low temperatures, and has broken through the forbidden area for the application of electric vehicles in extremely cold environments, which will play an important role in promoting the popularization and application of electric vehicles.
At the same time, this technology has also been affirmed by multiple authoritative institutions.
On October 19th, at the 27th Annual Meeting and Exhibition of the Society of Automotive Engineers of China hosted by the Society of Automotive Engineers of China, the project of "Key Technologies and Industrialization Applications of High-performance All-Climate Electric Bus Power Platform" co-ordinated by Rongsheng Mengguli won the first prize of the 2021 "China Automotive Industry Science and Technology Award" Science and Technology Progress Award.
The 2022 Winter Olympics are just around the corner. At that time, RongshengMeng Guli all-climate battery will be installed on 212 hydrogen fuel cell buses, walking in all corners of the Winter Olympics, guarding all moments of the Beijing Winter Olympics, and helping the successful holding of the Beijing Winter Olympics.
This will not be the end of rongsheng mengguli layout technology track. In the future, Rongsheng Alliance Guli will continue to be at the forefront of the reform of new energy utilization methods, continue to innovate in various new energy application fields, and help write a new chapter of harmonious coexistence between man and nature.
