O<\/strong>verview:<\/strong><\/p>\n Recently Automotive Industry Standards Committee (AISC) released standard AIS-156 and AIS-038 (Rev.02) Amendment 3. The test objects of AIS-156 and AIS-038 are REESS (Rechargeable Energy Storage System) for automobiles, and the new edition adds that the cells used in REESS should pass tests of IS 16893 Part 2 and Part 3, and at least 1 charge-discharge cycle data should be provided. The following is a brief introduction to the test requirements of IS 16893 Part 2 and Part 3.<\/p>\n IS 16893 Part2\uff1a<\/strong><\/p>\n IS 16893<\/a> is apply to the secondary lithium-ion cell used in electrically propelled road vehicles propulsion. Part 2 is about the test of reliability and abuse. It is consistent with IEC 62660-2: 2010 “Secondary lithium-ion cells used in electrically propelled road vehicles propulsion – Part 2: test of reliability and abuse” published by the International Electrotechnical Commission (IEC). The test items are: capacity check, vibration, mechanical shock, crush, high-temperature endurance, temperature cycling, external short-circuit, overcharging and forced discharging. Among them are the following key test items:<\/p>\n The items above are about cell performance. They require high performance of cell materials, like the separator. Therefore manufacturers should pay much attention to them<\/p>\n The above three tests require extra attention to the safety performance of the<\/strong> cell<\/strong>, especially the safety of the internal material<\/strong>s<\/strong>, such as the diaphragm.<\/strong><\/p>\n IS 16893 Part3\uff1a<\/strong><\/p>\n IS 16893 Part 3 is about safety requirements. It is consistent with IEC 62660-3: 2016 “Secondary lithium-ion cells used in electrically propelled road vehicles propulsion – Part 3: safety requirements”. The test items are: capacity check, vibration, mechanical shock, crush, high-temperature endurance, temperature cycling, overcharging, forced discharging and forced internal short-circuit. The following items are important.<\/p>\n The test method of forced internal short-circuit refers to IEC 62619.<\/p>\n Warm Tips<\/strong>:<\/strong><\/p>\n It is worth noting that although IS 16893 Part 2 and IS 16893 Part 3 have some of the same test items, the verdicts are not the same. Part 2 needs to assess the reliability of the cells, collect the basic data of reliability and abuse behavior. The test report needs to record the current, voltage and temperature data and describe the test results of the cells, and there is no requirement to determine whether the test results are passed or not. However, Part 3 specifies the conditions for passing the test, such as the cell cannot catch fire and explode during the test, if not, the test will fail.<\/p>\n If you have any other questions about this standard and the test application, please feel free to contact our customer service or sales.<\/p>\n Article Source: https:\/\/www.un383mcm.com\/news\/introduction-of-india-power-battery-standard-is-16893\/<\/a><\/p>\n Media Contact<\/span>\n
