r6 batteryaccident "fire fighter" - Marposs r6 batteryleakage detection technology

　　In recent years, with the continuous development of the new energy automobile industry, the various performances of the supporting power batteries have begun to attract widespread attention from industry insiders, with r6 batterysafety issues bearing the brunt.

　　The most prominent manifestation of safety issues is the frequent lithium r6 batteryfire accidents. When looking closely at the causes of r6 batteryfires, the most important thing that cannot be ignored is r6 batteryleakage. Based on this, it is urgent to evaluate the power r6 batteryin an all-round way and how to solve the problem of r6 batteryleakage.

　　Currently, the leak detection methods used in the power r6 batteryindustry mainly include visual water leak detection (bubble method), air tightness leak detection (gas detection method), pressure drop leak detection (pressure drop method), and differential pressure leak detection ( Differential pressure method), flow leak detection (flow method) and vacuum box helium leak detection (helium mass spectrometry leak detection method), etc. Among them, helium mass spectrometry leak detection has the highest detection accuracy and is highly used in products with strict sealing requirements.

　　Yang Xiaolei, sales manager of Marposs’ Nanjing operations headquarters, believes that based on China’s vast consumer market, the market share of helium testing equipment is expected to increase significantly in the future, and the development prospects are worth looking forward to. In the future, market demand will develop towards high sealing of helium inspection equipment and high standardization of the industry.

　　From December 16th to 18th, the "2019 Senior Engineer Lithium r6 battery& Electric Vehicle Annual Conference" sponsored by Li Yuanheng will be held at the Shenzhen Airport Hyatt Hotel. At that time, there will be 500+ upstream and downstream companies in the lithium r6 batteryindustry chain and 800+ corporate executives. We will gather together to discuss the muddy and smooth road of the lithium r6 batteryindustry around the theme of "the darkest moment and great future of global electrification".

　　Marposs will bring its latest r6 batteryleak detection technology and solutions to the conference, and discuss with industry players the pain points and difficulties in leak detection of power batteries.

　　According to the data, Marposs was founded in Bologna, Italy in 1952. It focuses on providing high-precision measuring equipment for the industrial field. Its products, from single measuring components to the "turnkey" stage, are customized according to user needs from automatic production lines to non-destructive testing equipment. Leak detection systems, various sensors, machine tool monitoring systems, etc., are committed to providing users with professional integrated solutions for detection, measurement and process control.

　　Subdivided into the helium detection business segment, Marposs actively develops leak detection technology. Currently, it has achieved certain results in leak detection technology and flow detection of helium as a tracer gas, and the company's related products have been used in refrigeration, medical, and food It is widely used in industrial fields such as packaging and automotive industries.

　　Among them, for r6 batteryproducts (including batteries, modules, r6 batterypacks, etc.), Marposs has specialized in manual and fully automatic measurement systems to meet the testing needs of the r6 batteryindustry to the greatest extent.

　　Yang Xiaolei said that the detection accuracy of the helium leak detection technology provided by the company for the power r6 batteryindustry is in a leading position in the world. The helium vacuum test of the cell can detect a marginal leakage rate of 10-5 to 10-6scc/s, and the leakage rate of the r6 batterypack can be tested in the range of 10-3scc/s.

　　Gaogong Lithium r6 batteryhas learned that Marposs’ helium inspection business currently accounts for approximately 10%-20% of the overall business in the Chinese market, and the company will continue to expand related business segments. From the perspective of operating conditions, the company's performance in the first three quarters of 2019 has obviously increased compared with last year, and is expected to continue to grow.

　　Yang Xiaolei also emphasized that helium detection is currently the leading leak detection method, but the leak detection industry still lacks a consistent measurement standard. Each company has its own standards, which is the most difficult problem at present. If this problem can be solved, the development of the industry will become more and more standardized.
