As the mainstream energy storage tool nowadays, lithium batteries are irreplaceable in importance whether in consumer electronic products such as mobile phones and tablets or in high-end products like electric vehicles, aviation, and communications.

With the development of the concept of green and low carbon, the global battery market is expected to grow five to ten times in the next decade.

As the standards with the highest recognition in the global market, EU standards also have a significant impact on other markets such as Asia, Africa, Australia, and South America. Now, let's take a look at the commonly used standards and test items for lithium batteries in the EU market.

Commonly Used Standards and Their Scopes of Application

IEC62133-2: Safety standards for rechargeable lithium-ion cells (Cell) and batteries (Battery), applicable to rechargeable lithium cells and battery packs.

IEC61960: Performance standards for lithium batteries, applicable to both rechargeable lithium cells (batteries) and non-rechargeable lithium cells (batteries). It assesses the discharge capacity performance of lithium batteries at room temperature, high and low temperatures.

IEC60086-4: Safety standards for primary lithium batteries, applicable to non-rechargeable lithium cells and lithium batteries.

IEC62281: Transportation safety standards for both rechargeable lithium cells (batteries) and non-rechargeable lithium cells (batteries).

IEC62368-1: Standards applicable to IT/AV products, and can also be used to evaluate power bank products.

EN50604-1: Applicable to the safety technical requirements of lithium batteries for light electric vehicles (LEV). The standard puts forward specific test items and requirements for lithium batteries used in LEV, providing the basis and criteria for such lithium batteries to enter the EU market.

IEC60335-2-114: Applicable to the safety technical requirements of lithium batteries for electric self-balancing vehicles (including balance bikes and hoverboards).

IEC62619: Safety standards for energy storage battery systems. The standard mainly covers various energy storage batteries used for photovoltaic, wind energy, backup power, and communication base stations.

IEC62620: Performance standards for energy storage battery systems. The standard mainly covers various energy storage batteries used for photovoltaic, wind energy, backup power, and communication base stations.

IEC62660-1: Standards for the performance requirements of secondary lithium-ion cells in electric vehicles (BEV, HEV).

IEC62660-2 & IEC62660-3: Standards for the reliability and abuse testing, and safety technical requirements of secondary lithium-ion cells in electric vehicles (BEV, HEV).

Common Test Items

• IEC62133-1 is a standard specification for the safety of rechargeable lithium cells and batteries introduced by the EU. It is the authoritative standard most widely certified internationally to evaluate the battery safety and reliability of lithium cells and batteries under various fault conditions.

The main test items include room temperature short-circuit test, casing stress test, room temperature short-circuit test, 55-degree short-circuit test, free-fall test, thermal abuse test, extrusion test, overcharge test, forced discharge test, mechanical impact test, vibration test, forced internal short-circuit test, etc.

• The high-risk items of IEC62133-1: thermal abuse test, extrusion test, 55-degree short-circuit test, forced internal short-circuit test, etc.

• IEC60086-4 is a safety standard for non-rechargeable lithium cells and batteries introduced by the EU.

The main test items include altitude simulation test, temperature cycling test, vibration test, mechanical impact test, external short-circuit test, drop hammer impact test, extrusion test, forced discharge test, abnormal charging test, free-fall test, thermal abuse test, non-correct installation test, over-discharge test, etc.
