Comparison and Analysis of Testing Standards for Power Lithium Batteries

Comparison and Analysis of Testing Standards for Power Lithium Batteries
The international standards for lithium-ion batteries published by IEC mainly include IEC 62660-1:2010 “Lithium ion power battery cells for electric road vehicles – Part 1: Performance testing” and IEC 62660-2:2010 “Lithium ion power battery cells for electric road vehicles – Part 2: Reliability and abuse testing”. The UN 38.3 “Recommendations on the Transport of Dangerous Goods, Standards and Test Manual” issued by the United Nations Transport Commission requires the testing of lithium batteries to ensure their safety during transportation.
The standards developed by ISO in the field of power lithium-ion batteries include ISO 12405-1:2011 “Electric Drive Vehicles – Lithium ion Power Battery Pack and System Testing Regulations Part 1: High Power Applications”, ISO 12405-2:2012 “Electric Drive Vehicles – Lithium ion Power Battery Pack and System Testing Regulations Part 2: High Energy Applications”, and ISO 12405-3:2014 “Electric Drive Vehicles – Lithium ion Power Battery Pack and System Testing Regulations Part 3: Safety Requirements”, which respectively target high-power batteries, high-energy batteries, and safety performance requirements, with the aim of providing optional testing items and methods for vehicle manufacturers.
The American standard UL 2580:2011 “Batteries for Electric Vehicles” mainly evaluates the reliability of battery abuse and the ability to protect personnel in the event of harm caused by abuse. This standard was revised in 2013.
SAE has a large and comprehensive standard system in the automotive industry. The SAE J2464: 2009 “Safety and Abuse Testing of Rechargeable Energy Storage Systems for Electric and Hybrid Electric Vehicles”, issued in 2009, is an early batch of vehicle battery abuse testing manuals applied in North America and around the world. It clearly specifies the scope of application and data collection required for each test item, and provides recommendations for the required sample quantity for the test item.
The SAE J2929:2011 “Safety Standard for Electric and Hybrid Battery Systems” issued in 2011 is a safety standard proposed by SAE on various power battery related standards issued before the summary. It includes two parts: routine testing and abnormal testing that may occur during the operation of electric vehicles.
SAE J2380: 2013 “Vibration Testing of Electric Vehicle Batteries” is a classic standard for vibration testing of electric vehicle batteries, based on the collection and statistical results of vibration load spectra during actual vehicle road driving. The testing method is more in line with the actual vibration situation of vehicles and has important reference value.
The United States Department of Energy (DOE) is primarily responsible for energy policy development, energy industry management, and energy related technology research and development. In 2002, the US government established the “Freedom CAR” project and issued the Freedom CAR Power Assisted Hybrid Electric Vehicle Battery Test Manual and the Energy Storage System Abuse Test Manual for electric and hybrid vehicles.
