Meaning
International safety standards define the requirements for secondary lithium cells and batteries used in electrical energy storage systems with a maximum voltage of 1500 volts. IEC 63056 focuses on the prevention of thermal runaway and the mitigation of hazards associated with large-scale installations. This document applies to fixed systems used for load leveling and emergency power.
Safety Standard
Specific design and test criteria ensure that the battery system remains safe under both normal and foreseeable misuse conditions. Compliance with iec 63056 is often a prerequisite for connecting a storage system to the electrical grid. The standard covers electrical, mechanical, thermal and chemical risks found in industrial environments.
Test Scope
Laboratories perform a series of trials to evaluate the reaction of the system to external fires and internal short circuits. During the evaluation of iec 63056, the battery is subjected to overcharge, forced discharge and high temperature storage. These tests verify that the enclosure and the management system prevent the spread of fire.
Compliance Outcome
Manufacturers receive a formal report that certifies the equipment meets the necessary safety benchmarks. Obtaining an iec 63056 certificate reduces the liability for the operator and simplifies the insurance process for the facility. It is a fundamental part of the technical file for any large battery project.
