Lithium-ion Battery Certification in India

The development of lithium-ion batteries has been an essential topic in the field of science and technology. The research and application of lithium-ion batteries have greatly contributed to the development of energy storage technology. UL Mark is a standard that ensures the safety of these battery packs. The UL Mark is issued by Underwriters Laboratories, a nationally-recognized organization that tests and certifies products against stringent standards.

The UL Mark is issued to lithium-ion battery packs with the battery capacity of the lithium-ion system which is mainly determined by the specific capacities of positive electrodes. This means that all lithium-ion products must meet these criteria to receive this mark.

In order to meet the needs of electric vehicles and other new energy storage devices, there are various standards and regulations that need to be followed. Therefore, each country will have its own requirements regarding how to test lithium-ion batteries for safety and performance.

About Lithium Battery

Lithium Ion Battery is one of the best energy storage systems available today. Lithium-ion battery packs provide deep cycle energy for a wide range of applications. The batteries are used in electric vehicles and other high-power applications. Lithium-ion batteries have a number of advantages over traditional lead acid batteries, which include:

• Longer cycle life
• Higher energy density
• Reduced weight and volume
• Environmentally friendly

Battery Safety Testing and Certification

The second step involves testing each batch of batteries to ensure that they meet all applicable safety standards before they are released into the marketplace.

The primary goal of battery safety testing is to ensure that batteries are safe to be used in proposed equipment. The tests performed on batteries are not only to test their ability to withstand high-temperature and high-current conditions but also to ensure that they can withstand the mechanical stress of usage in portable equipment.

The Most Common Battery Certification Process Includes Physical and Electrical Tests. These tests include:

• Dissolution testing:- This test measures the effects of temperature variations on a battery’s ability to hold a charge. It determines whether the battery will remain fully charged or gradually lose its charge over time.
• Cycle-life testing:- Cycle life testing determines how long a battery will last before it needs replacing. This test is important for determining whether it’s worth investing in a new one or not.
• Discharge testing:- Discharge testing is used to simulate actual use conditions, such as charging from an alternator or from another source. Discharge tests are usually done using specialized equipment that simulates varying voltage levels and currents during charging cycles
• The Voltage Test:- A high-voltage test will ensure that your batteries have sufficient power to carry out the job you have asked them to do. A low-voltage test will help you check if there are any internal problems with your battery.
• The Internal Resistance Test:- This checks if there are any internal defects within the battery, such as corrosion or sedimentation.
• The Capacity Test:- This tests whether your battery has enough capacity to perform at its optimum level.
• Crushing Test
• Low-pressure Test
• Continuous charging Test
• Vibration Test

BIS Certification for lithium-ion battery 

BIS certification is a process that ensures the safety of lithium-ion batteries. The main purpose of the BIS certification process is to provide a means of checking and assessing the safety of lithium-ion batteries, as well as a means for independent verification and third-party verification.

BIS certification for battery is designed to help ensure the safety of lithium-ion batteries. These batteries are used in electric vehicles and other applications where their performance must be verified before they can be presented for sale or use.

The BIS Certification Process Involves Two Parts:

• The first part involves testing the batteries themselves. This includes testing for defects and potential risks such as overheating, explosion, or fire. A battery may also be tested for leakage during charging or discharging.
• The second part involves testing equipment used with the battery such as an electrical power supply or charger. This part of the process will determine whether there are any problems with these components which could pose a risk to users if they are used with dangerous batteries.

How to Get BIS Registration for Lithium-ion Batteries?

In order to get BIS registration for lithium-ion batteries, the company must submit a detailed application and pay a fee. A lithium-ion battery is covered under the BIS compulsory registration scheme of BIS IS 16046 and ® – R Symbol registration.

• The application form is available on the website of BIS.
• To apply for a lithium-ion battery certification, you need to fill out an online application form and pay a fee.
• The application form requires information
• You can also upload scanned copies of documents to get BIS registration for lithium-ion batteries such as a Completely filled CDF/CCL form, Duly filled BIS application form, Business License of the manufacturing unit, Scope of Business License, ISO certificate of the manufacture, Marking Label / Details of Marking on the product, Authorization letter, Trade Mark Certificate, Photo ID of Authorized Indian Representative/ Authorized Signatory, Technical Specification Sheet of Product/user manual, UN 38.3 Test report

What will be the marking on Li-system Cell or Battery?

Marking on Lithium System Cells and Batteries as per IS 16046(Part-2):2018/ IEC 62133- 2:2018 and further referred as per IS 16047(Part-3):2018/IEC 61960-3:2017 shall be clear and durable as given below: -

• Secondary (rechargeable) Li or Li-ion 
• Cell or Battery Designation as per Cl.5.1 of IS 16047(Part-3):2018
• Polarity - Date of manufacture (which may be in code)
• Name or identification of manufacturer or supplier
• Rated capacity
• Nominal voltage

Conclusion

The industry has made great progress in five years, but there are still many challenges that need to be overcome. The BIS certification is an important step forward in improving the safety of lithium-ion batteries, but it is not enough. For example, we still need more testing equipment and more safety standards. In addition, we need to implement more effective mechanisms such as risk management and traceability systems. In summary, the BIS certification is an important step toward improving the safety of lithium-ion batteries. However, it will not solve all problems that exist within this industry. We must continue working together with other industries and government agencies to create a better tomorrow for all consumers!
