BIS said to implement new performance standards for EV batteries

The Bureau of Indian Standards (BIS) has issued performance standards for batteries for electric vehicles to ensure the safety of consumers, a senior official of the Ministry of Consumer Affairs said on Thursday.

BIS, the national standard-setting body operating under the Ministry of Consumer Affairs, has published the “performance standards for electronic vehicle batteries”, the official said.

The standard “IS 17855: 2022” has been formulated for lithium-ion traction batteries and systems of electrically powered road vehicles and has been harmonized with ISO 12405-4: 2018, the official added.

According to the official, the standard of the new EV batteries contains the test procedure for the basic characteristic of performance, reliability and electrical functionality for the battery packs and system for either high-power or high-energy application.

This standard is formulated taking into account actual scenarios for an electric vehicle, such as vehicle in parking (battery is not used for a long period of time), the battery system is shipped (stored) and the battery at low and high temperatures. Consequently, several tests have been included in this standard.

Electric vehicles run on an electric motor and rechargeable batteries. Over the past decade, electric vehicles have grown in terms of visibility and availability in the market. Most electric vehicles use lithium-ion batteries due to their high power-to-weight ratio.

Taking into account the safety aspect of batteries for electronic vehicles, the BIS is in the process of publishing two more standards related to batteries for various passenger and freight vehicles (L, M and N categories), the official said.
