Full title and description

Electrically propelled road vehicles — Test specification for lithium‑ion traction battery packs and systems — Part 2: High‑energy applications. This International Standard specifies test procedures and requirements for evaluating safety, electrical performance and behaviour of high‑energy lithium‑ion traction battery packs and systems intended for electrically propelled road vehicles.

Abstract

ISO 12405‑2:2012 defines test specifications tailored to high‑energy lithium‑ion traction battery packs and systems used in electric vehicles. It provides protocols for electrical pulse‑power characterisation, charge/discharge cycling, environmental and thermal conditioning, and safety/abuse tests intended to assess pack‑level behaviour under realistic and extreme operating conditions. The standard has been withdrawn and superseded by later parts in the ISO 12405 series.

Scope

Applies to lithium‑ion traction battery packs and systems intended for electrically propelled road vehicles where the energy content and pack design are classified as high‑energy applications. The standard specifies test methods to characterise pulse discharge/charge power, evaluate performance over environmental and cycling conditions, and assess safety‑related behaviours during abuse and fault conditions at pack and system level. Note: ISO 12405‑2:2012 has been withdrawn and later ISO 12405 parts (notably ISO 12405‑4:2018 and related parts) provide updated test coverage.

Key topics and requirements

• Pulse‑power characterisation profile and procedures (discharge and regenerative charge pulses at defined durations and SOC/temperature conditions) to determine short‑term power capability and regenerative behaviour.
• Electrical performance tests including charge/discharge cycling, capacity and internal resistance measurements at specified states of charge and temperatures.
• Thermal and environmental conditioning procedures to assess behaviour under temperature extremes and thermal soak conditions.
• Safety and abuse tests at pack/system level (thermal runaway propagation assessment, fault injection, short‑circuit and overcharge scenarios) to evaluate containment and mitigation features.
• Instrumentation, data acquisition and test‑reporting requirements to ensure repeatability and traceability of results across laboratories.
• Pass/fail criteria and conformity assessment guidance for the defined tests (as applicable to supplier/customer agreements and regulatory frameworks).

Typical use and users

Used by electric vehicle (EV) battery pack designers and manufacturers, vehicle OEMs, independent test laboratories, safety and homologation engineers, and research organisations to validate performance, safety and compliance of high‑energy traction battery systems. It is also referenced when developing supplier test contracts and for comparative evaluation of pack designs.

Related standards

ISO 12405 series (other parts such as ISO 12405‑1 and ISO 12405‑4), national adoptions/identical publications, and complementary standards such as IEC cell‑level test standards (for example IEC/ISO cell tests used in battery evaluation) and relevant vehicle safety and homologation regulations. ISO 12405‑4:2018 supersedes/updates aspects of the ISO 12405 test specifications for some performance and safety testing.

Q: What does it cover?

A: It covered pack‑level test procedures including pulse‑power characterisation (various short discharge and regenerative charge pulses), electrical performance tests, environmental/thermal conditioning and safety/abuse tests designed to evaluate behaviour, performance and safety of high‑energy battery packs.

Q: Who typically uses it?

A: Battery pack manufacturers, EV OEMs, independent test laboratories, regulatory and homologation bodies, and research institutions use or referenced this standard when developing and validating high‑energy traction battery systems.
