BIS formulates performance standards for EV batteries

The standard IS 17855: 2022 for these battery packs and systems is harmonized with ISO 12405-4: 2018.

This standard incorporates the test procedure for basic characteristics of performance, reliability, and electrical functionality for the battery packs and systems for either high power or high energy application, said the Ministry of Consumer Affairs.

This standard is formulated considering real-life scenarios for an electric vehicle such as the vehicle is in parking (battery is not used for an extended period of time), the battery system is being shipped (stored), operating battery at low and high temperatures, etc., accordingly, various tests are incorporated in this standard, it said.

Safety and performance are two critical aspects of electronic devices.

Requirements of battery system for use as a power source for propulsion of vehicles are significantly different from the battery used for consumer electronics or stationary use.

Electric vehicles are vehicles that operate on electric motors and rechargeable batteries. Over the past decade, Electric vehicles have grown in terms of visibility and availability in the market.

For the safety of consumers, reliability, and safety, Energy storage systems become a critical part of any EV.

Most EVs use Lithium-ion batteries because of their high power-to-weight ratio.

Further, keeping a view on the safety aspect of batteries for EVs, the Bureau of Indian Standard is in the process of publishing 2 more standards related to batteries for various passenger and goods carrying vehicles (L, M and N categories), the ministry said.
