Overview

EN 62133-2:2017/A1:2021 (CLC) is the European adoption of IEC 62133-2 Amendment 1 and specifies safety requirements for portable sealed secondary cells and batteries for lithium systems. This amendment (A1, September 2021) incorporates corrigenda and editorial/technical updates to the 2017 edition and is intended for batteries used in portable applications. It is widely used for regulatory compliance, conformity assessment and safety testing across CENELEC member countries.

Key topics and technical requirements

• Scope: Safety requirements for lithium-based portable sealed secondary cells and batteries, including test procedures and design evaluation.
• Charging procedures: Updated second charging procedure (clause 7.1.2) defines stabilization at highest/lowest test temperatures, constant-current/constant-voltage charging until current reduces to 0.05·I_A, and references a Table 2 for temperature and voltage/current limits.
• Mechanical abuse tests: Crush test (7.3.5) requires fully charged cells to be crushed between flat surfaces with a specified force device; the amendment specifies a force of 13 kN ± 0.78 kN and conditions for releasing force on abrupt voltage drop.
• Electrical abuse and protection: Over-charge requirements (7.3.6) clarify that battery overcharge protection circuitry, if provided, shall protect cells to prevent fire or explosion.
• Forced internal short-circuit and temperature conditioning: Design evaluation updates include ambient temperature conditions for tests (Table 5) with test temperatures defined relative to charging limits (±2 °C tolerance).
• Component standards: Annex F (informative) emphasizes that components relied upon for battery safety should meet appropriate component standards. Example references include IEC 60127 (miniature fuses), IEC 60738-1 (PTC thermistors), and IEC 60691 (thermal links).

Practical applications

EN 62133-2:2017/A1:2021 is applied to the design, testing and certification of lithium-based batteries used in:

• Portable electronics (smartphones, tablets)
• Power banks and battery packs
• Wearables and medical portable devices
• Handheld tools and portable instrumentation

Use of this standard helps manufacturers and test laboratories demonstrate battery safety, reduce risk of thermal runaway, and meet market access requirements in Europe and other regions recognizing IEC/CENELEC standards.

Who should use this standard

• Battery designers and OEMs developing lithium battery packs
• Compliance and safety engineers performing type and design evaluations
• Test laboratories conducting mechanical/electrical abuse tests
• Certification bodies and regulators assessing conformity to battery safety requirements

Related standards

• IEC 62133-2 / EN 62133-2 (base standard)
• Component standards referenced in Annex F: IEC 60127, IEC 60738-1, IEC 60691

Keywords: EN 62133-2:2017/A1:2021, battery safety, lithium systems, portable sealed secondary cells, CLC, IEC 62133-2, overcharge protection, crush test, forced internal short-circuit.
