IS 16298:2016 is the Indian Standard (BIS) for secondary batteries for renewable energy applications - general requirements and methods of test. This standard specifies general requirements and methods of test for secondary batteries used in renewable energy applications, such as solar and wind power systems. It covers performance evaluation, endurance testing, and functional characteristics to ensure the suitability and reliability of batteries for cyclical and float service in these demanding environments.
Specifies general requirements and methods of test for secondary batteries used in standalone and grid-connected renewable energy systems.

Practical Notes
! This Indian Standard is technically identical to IEC 61427-1:2013, which makes it crucial for manufacturers exporting to or importing from markets that follow IEC standards.
! The standard clearly distinguishes between two main test regimes: one for cyclic PV applications (Clause 8.4) and another for charge-discharge float mode (Clause 8.5) typical in hybrid or backup systems.
! Pay close attention to the test tolerances in Table 2, as inaccurate test equipment can lead to invalid or non-comparable results.

Frequently Asked Questions4
What is the purpose of this standard?+
To provide a uniform method for testing and specifying the performance of secondary batteries intended for use in renewable energy systems.
Is this standard for a specific battery chemistry like lead-acid or lithium-ion?+
No, it is a general standard applicable to all types of secondary batteries, but test conditions may need to be adapted based on the manufacturer's specifications for a particular chemistry.
What is the standard test temperature for determining battery capacity?+
The standard reference temperature is 25 °C with a tolerance of ±2 °C, as specified in Clause 7.
Does this standard cover battery management systems (BMS)?+
It primarily focuses on the battery cell or monobloc itself, but acknowledges the BMS as part of the test setup if it is integral to the battery's operation.
