25、ding battery, hybrid and plug-in hybrid electric vehicles has been accelerated in the global market, responding to the global concerns on CO 2reduction and energy security. This, in turn, has led to rapidly increasing demand for high-power and high-energy density traction batteries. Lithium-ion batt

In the light of rapidly diffusing hybrid electric vehicles and emerging battery and plug-in hybrid electric vehicles, a standard method for testing reliability and abuse requirements of l
27、ithium- ion batteries is indispensable for securing a basic level of safety and obtaining essential data for the design of vehicle systems and battery packs. This standard is to specify reliability and abuse testing for automobile traction lithium-ion cells that basically differ from the other cells
28、 including those for portable and stationary applications specified by the other IEC standards. For automobile application, it is important to note the usage specificity; i.e. the designing diversity of automobile battery packs and systems, and specific requirements for cells and batteries correspon
29、ding to each of such designs. Based on these facts, the purpose of this standard is to provide a basic test methodology with general versatility, which serves a function in common primary testing of lithium ion cells to be used in a variety of battery systems. For the requirements for cells differ d
30、epending on the system designs of battery pack or vehicle, and should be evaluated by the users, this standard does not provide any pass-fail criteria for the tests, but specifies a standard classification of descriptions for test results.
