MNRE (Ministry of New and Renewable Energy) recently issued a draft regarding testing guidelines for battery manufacturers to meet quality standards. The guidelines are specifically for performance testing of lead-acid and nickel-based chemistry type. The broad aim of the Ministry is to develop and deploy new and renewable energy for supplementing the energy requirements of the country.
MNRE has requested manufacturers to get their products tested and approved by Bureau of India Standards (BIS) certified labs. The draft guidelines are open to comments which are due by 18th April. The draft copy was prepared with inputs from stakeholders, including experts from test labs, BIS, and the battery storage industry.
The renewable energy sector is booming in the country. And, the government is trying to ensure the quality standards at par with the growth of the industry.
According to MNRE, following information must be provided by the manufacturer while submitting the batteries for testing:
- the material of the containers
- the separator used
- type of sealing adopted (in the case of sealed batteries)
- overall dimensions
The manufacturer will need to recommend the procedure to be followed to charge the cells and batteries. If the information is not provided by the customer, the procedure described in applicable standards will be followed.
Following short-term tests will be performed on all samples:
- capacity test
- retention of charge
- sulphation test
- water loss test
In case any test samples fail any one of the short term tests, the particular rating will be resubmitted for the testing.
Among the product range of cells and batteries from a manufacturer, the representation model of that particular cell and battery will be tested. The highest rated capacity sample will be subjected to all tests (including endurance tests), and the qualifying product will be issued test reports to all samples covered in the series.
