Main
IEC 62973-4:2021 applies to secondary sealed nickel-metal hydride battery technologies for auxiliary power supply systems used on rolling stock. This document specifies the requirements of the characteristics and tests for the sealed nickel-metal hydride cells and supplements IEC 62973-1 which applies to any rolling stock types (e.g. light rail vehicles, tramways, streetcars, metros, commuter trains, regional trains, high speed trains, locomotives, etc.). Unless otherwise specified, the requirements of IEC 62973-1 apply. This document also specifies the requirements of the interface between the batteries and the battery chargers. This document is to be used in conjunction with IEC 62675, IEC 63115-1 and IEC 63115-2.
