A collection of fires that occurred between 2017 and 2019 introduced South Korea’s power storage market to a standstill. New analysis seeks at present to make clear all of the causes of accidents and analyze many social elements that may trigger the continued incidence of accidents.
A collection of 28 consecutive battery fires that occurred in South Korea between 2017 and 2019 led the nation’s power storage market to finish paralysis.
The nation’s Ministry of Commerce, Trade and Vitality (MOTIE) reached some broad conclusions in its investigative report on the accidents. By taking methods aside and analyzing elements, it recognized many potential manufacturing defects and decided that some methods possible lacked ample safety towards electrical shock. It additionally makes use of moisture, mud, and salt mist exams to establish environmental administration weaknesses in battery methods.
As well as, MOTIE highlights the problem of poor set up strategies and finds issues that may come up when installers mix power administration and management system elements from totally different producer – even when such elements will not be designed for use as parts of an built-in system.
These elements, nevertheless, will not be all the explanations behind accidents, in keeping with new analysis from the Ulsan Nationwide Institute of Science and Expertise (UNIST) in South Korea. “Amua The research considers the impression and dangers related to social elements related to battery fires, which have hardly ever been thought of in earlier research,” the lead creator of the analysis, Ji-bum Chung, mentioned pv journal. “Though the chance of fireside is mitigated by the event of battery storage know-how, there are potential dangers corresponding to human error and regular accidents that may trigger individuals, organizations, and social contexts during which the know-how is used. .
In accordance with Chung, fires in Korea are socially constructed by environmental elements corresponding to sturdy incentives, inadequate regulation, the totally different cultural backgrounds of stakeholders, the strict linking varied sub-technologies and miscommunication, the systematic strain to hunt revenue. , and false sense of safety.

“These social elements affect the incidence of related social teams’ (RSGs) adverse interactions and result in adverse penalties such because the normalization of deviance and the hiddenness of the construction that accumulates in hearth hazards,” Chung additional defined. “Battery storage, an artifact created by social know-how, is seen negatively by these teams as a consequence of a collection of unintended fires. In consequence, in 2021, the Korean authorities modified its insurance policies on storage from unusually sturdy help to zero help. The chilly perspective of the federal government led to the deterioration of the profitability of batteries that acted as an impediment to the event of the business, together with the chance of fireside.
on paper”The social building of fireside accidents in battery power storage methods in Korea,” lately printed in Journal of Vitality Conservation, Chung and his colleagues introduced the outcomes of 24 interviews carried out in 2021 geared toward amassing totally different interpretations of stakeholders on the causes of battery fires, together with members who participated in two official investigation committee established by MOTIE.
“Semantic Community Evaluation (SNA) and Thematic Evaluation (TA) have been carried out on all textualized interview information to look at key points,” the researchers defined. “Throughout the interviews, we discovered that social elements, corresponding to insurance policies, rules, and organizational traits, are thought of an affect on battery hearth dangers.”
Additionally they used the social building of know-how (SCOT) concept to analyze the method of battery storage know-how building. This concept states that Expertise doesn’t decide human motion, however relatively, human motion shapes know-how.
The group concluded that RGSs don’t totally perceive the benefits and dangers of storage know-how and consider batteries as a technique to preserve financial incentives. “Such reckless use of know-how and lack of threat consciousness are motivations to forestall future technological dangers,” it mentioned. “Acceptable dangers might trigger members to make irrational selections based mostly on their pursuits. If a battery is abused, the chance of thermal runaway will increase. “
