Recently on 27th Dec 2023, the Bureau of Indian Standards (BIS) revised the standard for Storage cells/Batteries (IS 16270: 2014) for Solar applications to IS 16270: 2023.

The scope of this standard has been changed from “This standard applies to secondary cells and batteries of lead-acid and nickel-based chemistry” to “This standard applies to all types of secondary cells and batteries used in solar photovoltaic applications” The revised standard has been published to incorporate new chemistry now being used in solar applications.

The date of withdrawal for the old standard IS 16270: 2014 is 27 March 2024.

Revised Highlights of IS 16270: 2023

• Maximum Charge current in 4.3.3.a
• Inclusion of Lithium battery type and other electro chemistries in Table 1, 2
• Inclusion of standards for Lithium cells and batteries in 7.2
•  Introduction of long-duration capacity (C120) in 8.1
• Inclusion of capacity requirement of the rated capacity in 8.1.1

As of now, the BIS-CRS portal is not updated with the above-mentioned new chemistry cell/batteries.

However, we anticipate that the BIS portal will be updated soon. As soon as that occurs, manufacturers will be able to apply for BIS certification for storage batteries based on Li chemistry.
