▍BSMI Introduction Introduction of BSMI certification

BSMI is short for Bureau of Standards, Metrology and Inspection, established in 1930 and called National Metrology Bureau at that time. It is the supreme inspection organization in Republic of China in charge of the work on national standards, metrology and product inspection etc. The inspection standards of electrical appliances in Taiwan are enacted by BSMI. Products are authorized to use BSMI marking on the conditions that they are in compliance with safety requirements, EMC testing and other related tests.

Electrical appliances and electronic products are tested according to the following three schemes: type-approved (T), registration of product certification(R) and declaration of conformity (D).

▍What is the standard of BSMI?

On 20 November 2013, it is announced by BSMI that from 1^st, May 2014, 3C secondary lithium cell/battery, secondary lithium power bank and 3C battery charger are not permitted to access to Taiwan market until they are inspected and qualified according to the relevant standards (as shown in table below).

▍Why MCM?

● In 2014, rechargeable lithium battery became mandatory in Taiwan, and MCM began to provide the latest information about BSMI certification and the testing service for global clients, especially those from mainland China.

● High Rate of Pass: MCM has already help clients to obtained more than 1,000 BSMI certificates till now in one go.

● Bundled services: MCM helps clients successfully enter multiple markets in worldwide through one-stop bundled service of simple procedure.

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.IS 16893 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:High-temperature endurance: cells of 100 % SOC( BEV) and 80 % SOC( HEV) need to be placed at 130℃ for 30min.External short-circuit: cells of 100% SOC need to be shorted for 10 minutes at an external resistance of 5mΩ.Overcharging: application of voltage to twice the maximum voltage specified by the manufacturer or a power level of 200% SOC is needed. BEV needs to be charged with 1C and HEV needs to be charged with 5C.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.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.
