Over 50 cases of spontaneous combustion within a year
The "spontaneous combustion" of electric vehicles is a key area of consumer rights protection in 2020- although the current number is not large, it has received extremely high social attention. According to the statistical data from Lianpinzhong Consulting, there were 61 car self ignition/fire accidents in 2020, of which 51 were confirmed pure electric vehicle accidents, accounting for 84%, and the majority of the accidents were caused by power battery problems.
For example, last year a certain car model experienced three consecutive incidents of fire. In January 2021, a new energy vehicle owner caught fire while driving into a basement parking lot, causing the entire vehicle to burn beyond recognition. Once the core components of electric vehicles, such as batteries, have problems, it is easy to endanger the safety of consumers' lives. The concern for batteries is gradually increasing, which is about to become a hot topic for consumer complaints.
In fact, car companies are rushing to install "non fire battery packs", and as suppliers, battery manufacturers are also doing everything in their power to ensure battery safety.
BYD has launched the "blade battery that does not ignite", CATL has developed the "smoke only, no fire" battery, Xinwangda has developed the safe battery system "Xinwangda solution that does not ignite", Honeycomb Energy has released the thermal runaway systematic solution "Cold Bee", and the new power battery force Leading Pai New Energy has proposed a "four zeros" strategy, including zero risk
Ouyang Minggao, an academician of the CAS Member, said, "Battery safety technology is the first key point of the revolutionary breakthrough in battery technology, the first key to the performance upgrade of pure electric vehicles, and the lifeline of the sustainable development of electric vehicles. The research and development of power batteries should focus on safety, and strive to improve the safety technology of existing lithium-ion battery systems."
However, the number of recalls of new energy vehicles in 2020 still increased several times. Statistics show that in 2020, 21 automobile manufacturers implemented a total of 31 recalls of new energy vehicles, involving 94100 vehicles, nearly doubling the number of recalls compared to 2019. Equivalent to 1 out of every 14 cars sold being recalled. Among them, power batteries are the main reason for the recall of new energy vehicles. Last June, the Ministry of Industry and Information Technology issued a document requiring the investigation of safety hazards in new energy vehicles to reduce the risk of vehicle fires.
Lithium ion batteries, as the core components of new energy vehicles and electrochemical energy storage, have complex fire behavior and significant accident hazards, making traditional firefighting methods difficult to effectively respond.
The lithium-ion battery fire prevention and control technology product independently developed by Zhongke Zhonghuan is committed to solving the fire problems in the field of new energy. Through the organic combination of multi parameter coupling detection technology and lithium-ion battery thermal runaway prediction model, it achieves accurate judgment and multi-level pre alarm of battery fires, effectively reducing the false alarms and missed alarms that exist in traditional detection; Its unique jog jet technology can achieve rapid extinguishing and long-term suppression of lithium-ion battery fires, greatly protecting the safety of relevant personnel.
Anhui Zhongke Zhonghuan Defense Equipment Technology Co., Ltd. is a leading provider of early warning and comprehensive solutions for public safety in the transportation industry in China, committed to solving pain points for the industry and downstream customers. Based on its technological accumulation in the field of public safety in transportation, the company focuses on two major directions: new energy and public transportation. The core team's years of military technology accumulation have been continuously innovated and introduced into the civilian market, effectively improving the safety, reliability, and stability of downstream products.
