Battery standards are a set of rules, specifications, and guidelines that regulate battery design, production, and distribution widely. These standards ensure that batteries are safe to use, the quality remains consistent, and avoids dangerous risks such as fire, explosion, or damage to the device. Additionally, this standardization also helps manufacturers to ensure their products meet international usage requirements in various countries. Standardized batteries not only increase consumer confidence, but also lead to technological innovations that are more efficient, environmentally friendly, and sustainable.

This article takes a deeper look at battery standards, from the definition, why it matters, major international standard organizations, battery safety standard regulations, standards for lithium batteries and automotive industry, the difference with certification, to how to do a battery testing standard.

Key Takeaways

While certifications show that a battery has gone through testing and meets the battery standards, battery standards set the requirements.
The first and foremost priority when it comes to setting battery standards, especially with lithium-ion batteries. These standards require that batteries go through testing to prevent overheating, fires, or explosions.
Different industries use different standards: for consumer electronics it’s IEC, for automotive it’s ISO and SAE, and for transportation it’s UN38.3.
Before entering the market, testing is done first to ensure the electrical, mechanical, thermal, and environmental performance are in good and reliable working order to meet standards.
When manufacturers want to sell a product globally, they first have to meet the Global standards to ensure that the product meets safety and quality standards.

What are Battery Standards?

Battery standards is a set of technical requirements or official regulations set by institutions that have been standardized nationally and internationally to ensure that a battery has met safety, quality, performance, and environmental compliance aspects. This standard will generally regulate the entire battery assembly, ranging from physical design, system specifications, protection systems, to battery testing methods before finally being marketed in general.

Some trusted and commonly known international battery standards are IEC, ISO, UL, and UN38.3. If a battery product has passed the screening test by some of these standards, it ensures that the battery is safe for widespread use/commercialization. Technically, battery standards have the main function as an official reference for battery industry manufacturers to ensure their products remain of high quality, protect consumers, and support the development of battery technology to be more efficient and sustainable.

Why Battery Standards Matter?

Battery standards are crucial because it functions as a basis that ensures battery quality, safety, and reliability are at a satisfactory level before being used by consumers. This is because a battery that doesn’t have a clear standardization has the potential to experience failures such as overheating, internal short circuit, fire, or explosion that will endanger its users.

With standardization, each battery is ensured to have a good level of safety, has the appropriate technical specifications, and is also compatible with the appropriate system. Overall, battery standards are important because they protect consumers from low-quality batteries that pose a safety risk, help manufacturers maintain their battery production quality, and help support the development of safer and more sustainable technology.

Major International Battery Standards Organization

The organizations that determine the global standardization of batteries are important to ensure uniform regulation, safety, and quality of battery products. Some of these international standard organizations set technical guidelines that must be met by battery manufacturers if they want to market and commercialize their products globally. Below are some of the organizations that play a role in setting the standards of a battery internationally.

IEC (International Electrotechnical Commission)

An international organization that focuses on developing standards for electrical and electronic technology, including the battery industry. One of the standards it developed is IEC 62133 which regulates safety requirements on lithium-ion and nickel-based batteries for portable devices.

ISO (International Organization for Standardization)

This organization focuses more on developing battery requirements for the automotive and manufacturing industries. One of the standards issued by this organization is ISO 26262 which regulates the functional safety of vehicles, including battery systems in electric vehicles (EVs).

UL (Underwriters Laboratories)

A certification organization based in the United States and battery verification from this organization is essential if the product is to be marketed in North America. The safety requirements issued by this organization regarding batteries are UL 1642 (for lithium batteries) and UL 2054 (for battery packs).

UN (United Nations–UN38.3)

This organization regulates lithium batteries through the UN38.3 standard that requires each battery to pass altitude simulation tests, vibration, and impact tests before it’s able to be shipped by land, sea, or air.

SAE (Society of Automotive Engineers)

An organization that develops standardization in the automotive industry, including battery systems in electric vehicles to ensure their safety, interoperability, and performance.

Battery Safety Standards Regulation

Some of the safety regulations that batteries must comply with to ensure its safety, performance, and quality are as follows.

IEC 62133: Standardization that ensures safety in rechargeable batteries (lithium-ion and nickel-based) in portable devices. In its requirements the battery needs to pass tests from overcharge, short circuit, thermal abuse, to technical testing.
UL 1642 & UL 2054: Ensure battery cells and battery packs, especially lithium-ion, are free from fire problems, and have good structural integrity and system protection.
3: One of the mandatory regulations that ensures lithium batteries are capable of shipping safely by air, sea, and land. To obtain this standardization, the battery is required to pass altitude, vibration, shock, temperature, and short circuit simulation tests.
ISO 26262: A standard that focuses on a vehicle’s electrical system’s functional safety–including batteries–so critical system failures are minimized.
EU Battery Regulations & RoHS: This standardization generally regulates the restriction of hazardous substances, the obligation to label battery products, and the responsibility to recycle products to protect the environment and human health.

Battery Standards for Lithium-Ion Battery

To ensure that lithium-ion batteries are able to be marketed and used globally and nationally, several regulations and technical requirements are needed to ensure their safety, performance, and distribution feasibility. The importance of standardization on lithium-ion batteries is because these batteries have a high level of battery energy density, so have a high risk of overheating or thermal runaway. This is what makes standardization on lithium-ion batteries very important to do.

In its use and marketing, lithium-ion needs to be ensured to pass in three main aspects such as; safety, performance, and transportation. Therefore, the standards that need to be owned by lithium-ion batteries are IEC 62133 and UL 1642/ UL 2054 to ensure that the battery is not easily exploded or burned when used. The UN38.3 regulation requires batteries to withstand altitude, vibration, shock, or thermal tests before finally allowed to be shipped by land, sea, and air. If the lithium-ion battery is integrated into an electric vehicle (EV) system, then other regulations such as ISO 26262 are also needed.

Battery Standards for Automotive Industry

Batteries in the automotive industry such as electric vehicles (EVs) or hybrids also require global standardization to ensure reliability and safety. Standardization in these applications is even more stringent and comprehensive as they’re known to use high-voltage batteries and also store much larger amounts of energy. Therefore, the standardization required in industrial automotive includes electrical and functional safety, durability, and also resistance to extreme conditions.

Some of the standards that need to be owned by automotive systems are ISO 26262 which regulates vehicle electrical system functional safety, including battery management systems (BMS). SAE and IEC standards that regulate batteries and vehicles must have resistance to vibration, crash safety, extreme temperatures, overcurrent protection, and resistance to dust and moisture (IP rating). Additionally, batteries must also be standardized with UN38.3 and other environmental standards governing recycling and carbon emissions.
