What is a lithium battery storage guideline?

It is a guideline that outlines safe storage practices, including the charging and discharging of lithium-ion batteries, lithium metal batteries, and hybrid lithium batteries. If you would like to learn more about shipping of lithium batteries, we wrote this guide about just that.

Are lithium-ion batteries safe for electric energy storage systems?

IEC 63056, recently published by IEC, includes specific safety requirements for lithium-ion batteries used in electrical energy storage systems. These requirements assume that the battery has been tested according to BS EN 62619.

What temperature should a lithium battery be stored?

Storage at 5°C to 15°C is optimal. Since lithium batteries self-discharge, it is recommended that they must be recharged every 12 months. We can further divide it into short-term storage and long-term storage.

What is a safety standard for lithium batteries?

This international standard specifies requirements and tests for the product safety of secondary lithium cells and batteries used in electrical energy storage systems with a maximum voltage of DC 1500 V (nominal). Evaluation of batteries requires that the single cells used must meet the relevant safety standard.

How do you store a lithium battery?

The best storage method, as determined by extensive experimentation, is to store them at a low temperature, not below 0°C, at 40% to 50% capacity. Storage at 5°C to 15°C is optimal. Since lithium batteries self-discharge, it is recommended that they must be recharged every 12 months.

Why are lithium ion cells a hazard in a battery energy storage system?

The main critical component in a domestic battery energy storage system (BESS) and the source of many hazards is the lithium-ion cells themselves. These cells must be kept within the manufacturer’s specifications for current, temperature, and voltage to ensure safety.
