Lithium battery safety issued compulsory standards

Source: 2020 - 04 - 04 'hits: time released the lithium battery security mandatory standard GB 31241 - 2014, by the 'lithium ion battery safety standards working group to make, is our country's first national lithium ion battery safety standards. 'degree of intelligent portable electronic products is higher and higher, especially the wide use of the big screen, are increasing their power consumption. Some of the smart phone can only use one day, which brings great inconvenience to users and 'battery anxiety. 'the personage inside course of study He Penglin told our reporter, this phenomenon has given rise to a known as' charging treasure' mobile power hot market. According to our reporter understanding, gb31241 - 2014 is put forward by the Ministry of Industry and Information Technology, and 'lithium ion battery safety standards task force ( Four led electronic institute) To be responsible for the organization, is the first lithium ion battery safety standards issued in China. This standard reference to foreign advanced standards of mature detection method, and according to the state of the modified and perfected. Some innovative technical indicators have been tested. China's lithium ion battery industry experts after six years of extensive discussions, reached a consensus. This standard has been in December 2014, the state administration of quality supervision, inspection and quarantine and national standardization management committee for approval, and will take effect in August 2015. 'mainly through three aspects of this standard to ensure the safety of the charger: overall safety, security and other security components. 'He Penglin says,' in general, charging treasure first is a 'machine equipment, the first thing to meet the requirements of general electronic equipment safety standards. From the perspective of the whole machinery and equipment, which may be in danger of types of charging treasure including electric shock risk, fire danger, the danger of overheating, energy, and so on, especially the ac input charging treasure need to connect to the power grid, so the risk of electric shock to need attention. Second, the safety of the charger unit is mainly refers to the safety of the key components, including batteries or battery pack, protection circuit/protection, boost/buck circuit, shell, etc. 'thermal protection device fault may cause the charger fire or risk of overheating; If the battery short circuit, may cause the charger is on fire. 'other security measures include restrictions on the power supply, laser and light biological safety. Because of the different electronic products of the flame retardant performance difference is bigger, the charger as a power source, should be able to meet the requirements of electricity, to ensure that all electronic products can meet the corresponding requirement for flame retardant. China has become the world's largest producer and consumer of the lithium ion battery, highlighted standard formulation and implementation of the relevant departments of the importance of lithium ion battery safety regulation. It is understood that the Ministry of Industry and Information Technology certification and the national standard committee in gb31241 - supervision committee and other departments In 2014 set up the standard drafting group, the preparation and implementation of the project, has been paying close attention to and the height of the support, the leaders have repeatedly to participate in the discussion of the standard, and a lot of coordination work. 'the introduction of this standard to improve the safety and quality level of the lithium ion battery, standardize the market behavior of lithium ion battery industry, to optimize the design of the materials, technology, and management of buried battery products, and provides the technical basis of lithium ion battery products market access for the next step. 'he said, the first standard is a significant milestone of lithium ion battery industry management in China.
