IEC 61982:2012

Overview

IEC 61982:2012 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies performance and endurance test methods for secondary batteries (except lithium) used in the propulsion of electric road vehicles. This standard is essential for evaluating the reliability and efficiency of batteries such as lead-acid, nickel-cadmium (Ni/Cd), nickel-metal hydride (Ni/MH), and sodium-based batteries designed for electric vehicles (EVs). The 2012 edition supersedes earlier IEC standards IEC 61982-1:2006, IEC 61982-2:2002, and IEC 61982-3:2001, incorporating technical revisions that reflect advancements in battery testing protocols.

Key Topics

• Scope and Applicability
  Covers secondary batteries used specifically for electric road vehicle propulsion, excluding lithium-based technologies. It includes test methods to assess performance under typical operational conditions and endurance over extended cycles.

• General Test Requirements
  Ensures precise measurement with defined tolerances for electrical instruments, temperature controls, and electrolyte density measurements where applicable. It also addresses testing environments, sample conditioning, rest periods, and data recording protocols.

• Performance Tests
  Describes dynamic discharge testing both with and without regenerative charging. Tests simulate real-world driving cycles to evaluate battery capacity, power output, and rapid discharge characteristics.

• Endurance Testing
  Details cyclic charge and discharge procedures aimed at determining the battery’s operational lifespan, including endurance under continuous or regenerative charging scenarios. The standard specifies end-of-life criteria, cycling frequency, and reconditioning procedures to evaluate battery durability.

• Battery System Testing
  Provides guidelines for assessing complete battery systems, covering energy content determination, life testing, maximum power capabilities, internal resistance, charge efficiency, self-discharge rates, and handling of operational extremes.

• Ni-MH Battery Specific Procedures
  Includes annexed normative test procedures tailored to nickel-metal hydride batteries employed in hybrid electric vehicle (HEV) propulsion.

Applications

IEC 61982:2012 is critical for manufacturers, test laboratories, and quality assurance professionals involved in developing and validating secondary batteries for electric vehicles such as:

• Electric and Hybrid Road Vehicles
  Supporting performance validation for lead-acid, Ni/Cd, Ni/MH, and sodium-based batteries used in propulsion systems.

• Battery Design and Innovation
  Guiding development of battery technologies with improved endurance and performance metrics aligned with international standards.

• Regulatory and Compliance Testing
  Serving as a benchmark for safety, reliability, and performance criteria in certification processes for vehicle batteries.

• Energy Management Systems
  Integrating testing protocols to evaluate battery management systems (BMS) and optimize charge/discharge cycles.
