Under the promotion of the national "dual carbon" strategy, energy storage power stations are an important link in promoting the transformation of new energy. Lithium ion battery energy storage, as the most rapidly developing form of energy storage, will see a significant increase in its overall capacity during the 14th Five Year Plan period. However, the problem of thermal runaway warning and fire suppression in large-scale lithium-ion battery energy storage systems has not been solved, and fire or explosion accidents caused by thermal runaway occur from time to time.
According to incomplete statistics, there have been over 50 energy storage plant fire accidents worldwide in the past decade, which have had a negative impact on the development of the industry. The most influential accident in China was the "4.16" incident in Beijing in 2021, which caused a fire and explosion resulting in 2 deaths, 1 injury, and 1 loss of contact; On January 12, 2022, a large truck loaded with lithium batteries caught fire on the Beijing Hong Kong Macau Expressway in Jiangxia District, Wuhan due to thermal runaway inside the battery; In a foreign accident, on July 30, 2021, a fire broke out during the commissioning of the Victoria energy storage project in Australia, which lasted for 4 days before being extinguished; On January 12, 2022, a fire broke out in the battery storage building of SK Energy Company in the southern district of South Korea. Just five days later, the energy storage system in the solar power plant in Singu ri, Niubao gun, Jungwei gun, Gyeongsangbuk do, Yicheng, caught fire due to thermal runaway inside the battery.
Since the "Beijing 4.16" incident, the safety issues of lithium-ion battery energy storage have risen to unprecedented heights, and industry insiders have also realized the shortcomings of current safety prevention and control technologies. Several months later, two ministries and commissions also issued policies requiring safety and online monitoring technology to be essential. To this end, Wuhan Yunzhan Technology Co., Ltd. has proposed a safety online monitoring solution for lithium-ion battery energy storage power stations. With unique nano particle detection technology as the core, combined with multi feature gas detection, artificial intelligence algorithms and other technologies, it realizes the monitoring and early warning of safety hazards in the lithium-ion battery body, electrical equipment, and operating environment within the energy storage system, improves the overall safety prevention and control level of the energy storage power station, significantly reduces the probability of safety accidents, enhances the intelligent monitoring level and operation and control efficiency of the energy storage power station, and reduces the pressure of human labor.
Functional Features
01. Thermal runaway warning for battery body
It can monitor the particulate products and various characteristic gases generated by battery thermal runaway, and adopt intelligent algorithms for multi-source data fusion to achieve early warning of battery thermal runaway.
02. External security hazard monitoring and warning
It can monitor electrical equipment and operating environment outside the battery body, detect safety hazards such as poor connection of external battery joints, overheating, insulation defects, and discharge early, and achieve safe online monitoring of the entire prefabricated cabin.
03. Active detection
Adopting active sampling detection method has a faster response speed than traditional passive sensing and diffusion detection methods, and is more suitable for scenarios such as energy storage power stations that require high alarm speed.
