Liu Shuang, Deputy Director of Hefei Science and Technology Bureau
Since the Ministry of Transport comprehensively and deeply promoted the development of green transportation, the country has made efforts to build a strong transportation country and develop green transportation. Driven by the dual pressures of emission regulations and energy consumption, "electrification" has become an indisputable trend in the global automotive industry.
Wang Fengyu, Secretary General of the Urban Public Transport Branch of the Chinese Society of Civil Engineering, pointed out in his speech: "In the process of the vigorous development of new energy vehicles, some safety hazards are inevitable. Since May this year, the national regulatory platform for new energy vehicles has found 79 safety accidents involving new energy vehicles, of which 7% were passenger cars. Upon closer examination of the causes of the accidents, the main issue is the use of power batteries. How to improve the operational safety of new energy vehicles and prevent major safety accidents from occurring is an important issue related to people's livelihood and the construction of a harmonious society
Wang Fengyu, Secretary General of the Urban Public Transport Branch of the Chinese Society of Civil Engineering
As Wang Fengyu said, in the past few years, new energy vehicles have become a typical case of China's automotive industry "overtaking on the curve", and the industry's development has shown a thriving trend. However, it cannot be avoided that behind the great prosperity of new energy vehicles, problems and hidden concerns still exist. Accidents such as fires and spontaneous combustion occur occasionally, and the focus seems to be on one point - the safety performance and protection of power batteries. How to solve the problem of power battery safety? This is a common issue for the entire industry.
The key to solving the "thermal runaway" of batteries and solving the security problems of new energy vehicles
At the beginning of the forum, Wang Zeshan, an academician of the CAE Member and the winner of the National Highest Science and Technology Award, introduced in a speech entitled "Green Travel and Safety Guarantee" that in 2018, the sales of new energy vehicles in China were 1.25 million, and more than 40 electric vehicle fire accidents were publicly reported online; Since April 2019, a series of new energy vehicle fire accidents have occurred in China, affecting multiple car manufacturers and attracting high social attention. Since April 2019, a series of new energy vehicle fire accidents have occurred in China, affecting multiple automobile manufacturers. Safety issues have become a "roadblock" for the promotion of new energy vehicles. Fundamentally, safety accidents of new energy vehicles are mainly caused by thermal runaway of power batteries.
Wang Zeshan, academician of the CAE Member and winner of the National Highest Science and Technology Award
Academician Wang suggests that the prevention and control of fires in new energy vehicles should comprehensively consider both the intrinsic safety of batteries and the overall security design of the vehicle. Starting from improving the stability of battery positive and negative electrode materials, optimizing battery separator materials, increasing melting temperature, developing flame-retardant or non combustible electrolytes, improving battery thermal management systems, timely warning and troubleshooting of faulty batteries, developing fire prediction and warning technologies, and fire extinguishing technologies, government agencies, enterprises, research institutions, and end users should work together to create a healthy industrial development environment.
Since the 1990s, lithium based batteries have been widely used in portable electronic devices, electric vehicles, electrochemical energy storage stations, and other power systems, making battery safety design and application a research hotspot. During the forum, Dr. Wang Fang, a professor level senior engineer, discussed the safety design and application of electric vehicle power battery systems.
In general, the ultimate form of electric vehicle fire is battery thermal runaway. The comprehensive safety technology and evaluation of batteries are a systematic engineering. Batteries are electrochemical carriers, and their state is constantly changing throughout their entire life cycle. The possibility of thermal runaway also exists forever, "said Wang Fang. The improvement of power battery energy density is bound to bring challenges to battery safety. In recent years, with the rapid increase in battery energy density, the nodes where batteries experience thermal runaway are also advancing. How to improve is a question that needs to be considered.
Professor level Senior Engineer Dr. Wang Fang
对此，王芳建议，材料、电芯、BMS和系统都应该满足相应的安全需求。
The manufacturing process and quality control level of the product also need to be improved. Due to subsidy policies and other reasons, some manufacturers' product development cycles are too short. After the complete marketization of new energy vehicles in the future, battery manufacturers can use the rapidly developing BMS technology to manufacture products that meet the needs of the industry and the people. This is a magic weapon for battery manufacturers to establish a long-term foothold in future competition.
The healthy development of any industry requires collective wisdom and effort, especially in the lithium battery industry. In the first half of the forum, a dialogue was held simultaneously with the participation of Fang Jianhua, a member of the China Electric Vehicle Hundred People Association, Dr. Wang Fang, a professor level senior engineer, Sun Jinhua, an academician of the European Academy of Sciences, Zhang Shaoyu, Deputy Director of the Testing Center of the Tianjin Fire Research Institute of the Ministry of Emergency Management, Huang Yaliang, General Manager of Jiujiang Public Transport, Liu Peng, Deputy Secretary General of the National Big Data Alliance for New Energy Vehicles, and Meng Fanbao, Executive President of Anhui Zhongke Zhonghuan Defense Equipment Technology Co., Ltd. Experts provided suggestions and recommendations for the sound development of the lithium battery industry from the upstream, midstream, and downstream of the industry chain, focusing on "new energy, new standards, and new applications".

Standardize technical calibration, cooperate with supporting enterprises to actively act
Faced with the fire incidents of new energy vehicles that directly endanger the safety of people's lives and property, the industry regulatory authorities attach great importance to them. In recent years, the national security standards for new energy vehicle power batteries have injected a "booster" into the industry and end users. In the second half of the forum, Dong Haibin, Deputy Director of the First Testing Department of the Tianjin Fire Research Institute Testing Center of the Ministry of Emergency Management, interpreted the revised version of CCCF/XFJJ-01 "General Technical Requirements for Fire Prevention and Control Devices of Power Lithium ion Battery Boxes for Electric Vehicles" on June 6, 2019.
Dong Haibin, Deputy Director of the First Testing Department of the Tianjin Fire Research Institute Testing Center of the Ministry of Emergency Management
Dong Haibin introduced that the General Technical Requirements for Fire Prevention and Control Devices of Lithium ion Power Battery Boxes for Electric Buses were formulated on July 13, 2018 and revised on June 6, 2019, which put forward new requirements for fire prevention and control devices. Detailed technical calibration has been carried out for installation location, storage method, working pressure limit, working temperature range, fire suppression medium requirements, etc., which is applicable to the standard formulation and technical appraisal of fire prevention and control devices for lithium iron phosphate power lithium-ion battery boxes.
Under the strong promotion of the priority policy for public transportation, the scale of promotion and application of new energy public transportation in China has basically achieved full coverage. As the main transportation vehicle for public transportation, new energy buses have a large volume and carry many passengers. Once a safety accident such as battery fire occurs, the consequences are unimaginable. As a major user of new energy buses, transportation companies must take action in the safe use and management of new energy vehicles.
In recent years, with the advancement of vehicle technology, Hefei Public Transport has taken the lead in proactive safety measures and widely adopted new safety technologies. Xia Bangjin, Deputy General Manager of Hefei Public Transport, stated in his speech that in the practice of safety management of new energy vehicles, Hefei Public Transport has started from three aspects: the application of strengthened safety facilities in the selection of new vehicles, the use of safety facilities and equipment, and the maintenance of safety facilities and equipment, such as installing battery compartment fire extinguishing devices, flammable volatile alarm systems, etc., and strengthening the management of fire safety technology for new energy vehicles to eliminate safety hazards in their infancy.
Xia Bangjin, Deputy General Manager of Hefei Public Transport
Fire prevention and control is the root of new energy vehicle power battery fire protection. In this professional technology field, the University of Science and Technology of China, which is also located in Hefei and has a State Key Laboratory of fire science, can say it has a say. During the forum, Professor Wang Qingsong from the University of Science and Technology of China gave a speech titled "Exploration of Fire Characteristics and Prevention Technologies for Lithium ion Batteries". Wang Qingsong discusses the safety issues of lithium-ion batteries, the characteristics of thermal runaway fires in individual batteries, the risk of thermal runaway propagation in battery packs, the preliminary conclusions, difficulties, and challenges of lithium-ion battery fire prevention and control from four aspects. He also provides a fire prevention and control strategy - four lines of defense: precise detection of lithium-ion battery thermal runaway mechanisms, simulation of lithium-ion battery fires, improvement of intrinsic safety of lithium-ion batteries, and rapid and effective extinguishing of large-scale battery systems.
Professor Wang Qingsong from the University of Science and Technology of China
Whether it is policy guidance or expert opinion, various signs indicate that the safety protection of new energy vehicle lithium batteries is a systematic project. In addition to the "top-level design" mentioned by industry regulatory authorities, the technological upgrading and product innovation of new energy vehicle lithium battery security supporting suppliers are also the key to "preventing problems before they occur" for new energy vehicles. At the forum, Guo Yukun, a high-level team from Anhui Province and Executive Vice General Manager of Zhongke Zhonghuan, gave a report on "Research on Fire Prevention and Control of Lithium ion Battery Boxes", and also released Zhongke Zhonghuan's innovative continuous cooling suppression type lithium battery safety protection device - pump type perfluorohexane fire suppression device.
Guo Yukun, Executive Vice General Manager of Zhongke Zhonghuan
Guo Yukun introduced that research on fire prevention and control of lithium-ion battery boxes can be divided into two aspects: main and passive. Its fundamental purpose is to capture temperature changes, achieve early warning, and cut off the possibility of fire occurrence from the source; And real-time monitoring of the battery box is carried out to promptly extinguish fires and continuously cool down to prevent reignition in case of thermal runaway, thereby effectively suppressing fires. The Zhongke Zhonghuan pump group perfluorohexane fire suppression device achieves precise, efficient, continuous, and friendly safety protection and fire suppression for power batteries through the country's first continuous cooling suppression mechanism.
When it comes to the new energy bus industry in Anhui Province, Ankai is definitely the undisputed "leader". Relying on the industry's only "National Electric Bus System Integration Engineering Technology Research Center" and national postdoctoral research workstations, Ankai has formed a comprehensive layout of pure electric buses, plug-in hybrid buses, and hydrogen fuel cell buses, promoting the upgrading of new energy product quality and technological level while also doing sufficient work in vehicle safety.
The safety of new energy buses is the bottom line barrier for the lives and property of users, a huge protection for the smooth, rapid, and healthy development of the entire new energy vehicle industry, and a red line for the development of an enterprise. No matter how much attention is paid to safety issues, it cannot be overemphasized. "During the forum, Ding Zhuan, director of Ankai Bus New Energy Research Institute, said that Ankai has established a vehicle safety guarantee system from multiple details in six dimensions: vehicle safety, control safety, high-voltage safety, battery safety, charging safety, and monitoring safety, to ensure the safe use of vehicles in all aspects.
