IEC 62933-5-4 Ed. 1.0 en:2026

Full Description

IEC 62933-5-4:2026 This part of IEC 62933 primarily describes the safety test methods and procedures for
grid-connected energy storage systems where a lithium ion battery-based subsystem is used.
This document provides test methods and procedures to validate safety issues specifically
related to the use of a lithium ion battery-based subsystem, primarily based on IEC 62933-5-1,
which establishes criteria for ensuring the safe applications and use of electrical energy storage
systems of any type or size, and IEC 62933-5-2, which further specifies safety provisions arising
from the use of an electrochemical storage subsystems in EES systems.
All test methods and procedures are based on the requirements of IEC 62933-5-2. This
document includes only the test methods specifically related to lithium ion battery-based BESS
and is based on actual tests.
