Lithium battery is quite hazardous and require UN 38.3 standard transport testing and other regulations before being transported from one location to another. Any lithium battery is tested to UN 38.3 to ensure the battery complies with international rules and regulations for battery transport.

UN ECE Regulation R100

The ECE R100 standard test is conducted on electric vehicle batteries to ensure adequate safety. ECE R100 provides safety protection when charging electric vehicle batteries. To ensure this rule is met, electric vehicles should not be moved or driven while the battery is charging, and direct contact should be avoided.

The ECE R100 also ensures that electric vehicles maintain accurate positioning without cracks while driving. ECE R100 is only suitable for M+N electric vehicles with a top speed of 25km/hr. Therefore, this standard also applies to voltage conversion of electric vehicles.

International Electrotechnical Commission (IEC) 62619

International Electrotechnical Commission 62619 specifies the requirements required for the safe use of secondary lithium batteries and battery packs. It ensures that all lithium batteries are safe for use in electronics and other applications. International Electrotechnical Commission 62619 standard test requirements apply to stationary and moving applications.

IEC 62619 is also ideal for testing the safety of energy storage batteries. Energy storage batteries include secondary lithium batteries and batteries used in simple electronic devices such as cell phones to keep them stationary.

According to IEC 62619, batteries should withstand certain temperatures in the testing machine room. IEC 62619 specifies testing requirements to be performed on a series of testing machines at a temperature of 25±5°C.

Underwriters Laboratories (UL) 1642

UL 1642 standard requirements cover primary and secondary lithium batteries used in electronic product applications. It is suitable for different kinds of lithium batteries, whether they are single cells, double cells or multi-cell electrochemical cells connected in parallel or in series. Lithium batteries contain components such as metallic lithium, alloys, and lithium ions, which help convert chemical energy into electrical energy through a chemical reaction process. UL 1642 ensures the safety of lithium batteries in applications by reducing risks related to fire, explosion, etc. UL 1642 requirements apply to the use of lithium batteries as product power supplies.

Underwriters Laboratories (UL) 2580

Underwriters Laboratories 2580 standard requirements ensure correct evaluation of electrical energy storage. It ensures that electrical energy storage meets its safety requirements to withstand environmental impacts under any conditions and conditions in which consumers handle it. UL 2580 protects consumers from hazards caused by improper use of lithium batteries. Electrical energy storage evaluation process based on UL 2580, including design and module and manufacturer recommended initials for specified charge and discharge values.
