IEC 62620-2014 pdf Secondary cells and batteries containing alkaline or other non-acid electrolytes – Secondary lithium cells and batteries for use in industrial applications

This International Standard specifies marking, tests and requirements for lithium secondary cells and batteries used in industrial applications including stationary applications. When there exists an IEC standard specifying test conditions and requirements for cells used in special applications and which is in conflict with this standard, the former takes precedence. (e.g. IEC 62660 series on road vehicles). The following are some examples of applications that utilize the cells and batteries under the scope of this standard. • Stationary applications: telecom, uninterruptible power supplies (UPS), electrical energy storage system, utility switching, emergency power and similar applications. • Motive applications: fork-lift truck, golf cart, AGV, railway, and marine, excluding road vehicles. Since this standard covers batteries for various industrial applications, it includes those requirements, which are common and minimum to the various applications. This standard applies to cells and batteries. If the battery is divided into smaller units, the smaller unit can be tested as the representative of the battery. The manufacturer clearly declares the tested unit. The manufacturer may add functions, which are present in the final battery, to the tested unit.
EXAMPLE 1 —-INR54/222/H/-20+50/70 would designate a cylindrical Li-ion secondary cell, with a nickel-based positive electrode. Its maximum diameter is between 53 mm and 54 mm, and its overall height is between 221 mm and 222 mm. It is designed for high discharge rate. Its low temperature grade is -20 °C. Its high temperature grade is 50 °C. It applies for both cycle and stand-by application. Its capacity retention after 500 cycles to rated capacity is between 70 % and 74 %. EXAMPLE 2 —ICP25/1 50/1 50/E/0+60/60 would designate a prismatic Li-ion secondary cell, with a cobalt-based positive electrode. Its maximum thickness is between 24 mm and 25 mm, its maximum width is between 1 49 mm and 1 50 mm, and its overall height is between 1 49 mm and 1 50 mm. It is designed for low discharge rate over a long period. Its low temperature grade is 0 °C. Its high temperature grade is 60 °C. It applies for both cycle and stand-by application. Its capacity after 500 cycles to rated capacity is between 60 % and 64 %. EXAMPLE 3 —INR50/1 50/M/-30NA/75 would designate a cylindrical Li-ion secondary cell, with a nickel-based positive electrode. Its maximum diameter is between 49 mm and 50 mm, and its overall height is between 1 49 mm and 1 50 mm. It is designed for medium discharge rate. Its low temperature grade is -30 °C. Its high temperature grade is NA. It applies for cycle application only. Its capacity retention after 500 cycles to rated capacity is between 75 % and 79 %.
