Overview

EN 61881-3:2012/A1:2013 is the CENELEC amendment to IEC 61881-3 covering electric double-layer capacitors (EDLCs) used in railway rolling stock power electronics. It updates test methods, definitions and acceptance criteria specific to EDLC cells, modules and banks for traction and on-board power applications. The amendment was approved in 2013 and endorsed for national implementation by CENELEC members.

Key Topics

• Scope: Addresses EDLCs as part of capacitors for power electronics on rolling stock (railway vehicles).
• Definitions: Revises the definition of maximum operating temperature (case temperature at which the capacitor may be operated) and deletes a previous definition (3.19).
• Short-circuit test (replaces “surge discharge test”):
  • Preconditioning and initial measurement of capacitance and internal resistance required.
  • Capacitor charged to rated voltage within 5 minutes, held for 5 minutes, then short‑circuited; repeated five times.
  • Discharge circuit resistance must be ≤ internal resistance of the capacitor or 1 mΩ (whichever is lower).
  • Post-test measurements and acceptance by agreement between manufacturer and purchaser; no visible damage or electrolyte leakage allowed.
• Endurance cycling test (revised procedure):
  • Preconditioning, initial/final capacitance and internal resistance measurements.
  • Test temperature: 10 °C below the maximum operating temperature specified by the manufacturer; temperature measured at the cell case or hottest cell in a module.
  • Charge/discharge cycling steps specified with currents expressed as mA/F per cell (e.g., 5 mA/F and 50 mA/F) and defined voltage hold times.
  • End-of-test criteria: capacitance reaching 70% of initial or internal resistance reaching 200% of initial (module/bank end-of-life when first cell reaches criteria).
  • Acceptance: unless otherwise agreed, capacitance ≥ 70% of initial and internal resistance ≤ 200% of specified; no leakage or visible damage.
• Bibliography addition: IEC 60529 (IP Code) included.

Applications

This standard is used to ensure safe, reliable EDLC performance in railway power electronics such as:

• On-board energy storage and regeneration systems
• DC link smoothing and peak shaving in traction inverters
• Auxiliary power and braking energy recovery systems

Who uses it:

• Rolling stock manufacturers and system integrators
• Capacitor and module manufacturers
• Test laboratories and certification bodies
• Procurement/specification engineers and maintenance teams

Related Standards

• IEC 61881-3:2012 (base international standard)
