The IEC 62660-1 standard is an international test standard for lithium-ion secondary batteries in newenergy vehicles, including battery electric vehicles (BEV) and hybrid electric vehicles (HEV). It serves to assess the performance of battery cells and its evaluation items include capacity (Ah), power density (W / l), energy density (Wh / l), storage life, and cycle life. Only battery cells that comply with the variety of indicators can be used in new energy battery pack design. This application note will focus on the relevant electrical tests introduced in the IEC 62660-1: 2010 standard, and explain howto implement the test plan using the Chroma 17010 charge and discharge test system.
IEC 61960 is an international standard for testing lithium-ion secondary battery cells on portable devices. The objective is to evaluate the performance of battery cell and battery for capacity, cycle performance and internal resistance. At present, this standard has been used as the reference for proposed test plan in the relevant specifications of battery cell or battery in Japan, China, and other countries. This article focuses on introducing the related electrical tests in the IEC 61960:2011 specification and explains how to implement the test plan through the Chroma 17010 charge and discharge test system.
