IEC 62928 Cycle Life Testing of Railway Battery Systems
The IEC (International Electrotechnical Commission) Standard 62928 is specifically designed to address the unique demands placed on railway battery systems. This standard focuses on ensuring that these batteries can withstand the rigorous, long-term operational conditions encountered in rail transport applications. The test methodology outlined in this standard allows for a comprehensive evaluation of the cycle life and durability of railway batteries by subjecting them to repeated charge-discharge cycles under controlled conditions.
The primary goal is to assess how well the battery maintains its performance characteristics over time, which is crucial given the demanding operational environments railways face. This includes exposure to wide temperature ranges, mechanical stresses from movement, and frequent charging/discharging demands. By adhering to this standard, manufacturers can ensure their products meet the stringent requirements set by international regulatory bodies.
The test procedure involves placing batteries in a controlled environment where they undergo repeated cycles of charge and discharge until failure or predetermined end conditions are met. The number of cycles varies based on the specific type of battery being tested but typically spans several thousands to tens of thousands of cycles depending upon the expected lifespan of the product.
During testing, various parameters need to be closely monitored including open circuit voltage, internal resistance, capacity retention, and state-of-charge. These metrics provide valuable insights into the health and longevity of each battery unit tested. Compliance with IEC 62928 not only enhances safety but also contributes significantly towards reducing maintenance costs and increasing reliability across all modes of rail transit.
Besides the technical aspects, there are important considerations for specimen preparation which involve ensuring that samples represent actual usage scenarios as closely as possible. This includes selecting appropriate types and sizes of batteries representative of those used in railway applications. Additionally, proper handling during transportation to laboratories ensures consistency throughout testing processes.
