To Combat Recurring EV Fire Incidents, BIS Develops Performance Standards for Electric Vehicle Batteries


India is witnessing a sharp rise in the demand for electric vehicles, but it also raises some concerns about its safety due to the recent fire incidents with electric vehicles. The Bureau of Indian Standard (BIS) has developed the standard for the batteries used in electric vehicles to manage the rising concern with e-vehicles.

The National Standard Body of India released an official notification stating that the standards have been released for Test Specifications for Lithium-ion Traction Battery Packs and Systems (Performance Testing) for Electrically Propelled Road Vehicles. The standard IS 17855:2022 for battery packs and systems is integrated with ISO standards like 12405-4:2018.

The standard formulated by BIS integrates the test procedure for the basic characteristic of performance, reliability and electrical functionality for either high power or high energy application battery packs and systems. This standard is based on real-life scenarios for an electric vehicle, including a vehicle is in parking (battery not being used for an extended period), the battery system is being (Stored), Using the battery at low and high temperatures, and various other tests are included in this standard based on these scenarios.

Further, the Bureau of Indian Standard (BIS) is in the process to publish two more standards for battery packs and systems for various passenger and goods-carrying vehicles related to L, M and N categories.

Due to their high power-to-weight ratio, most Electric vehicles use Lithium-ion batteries. The standards formulated by BIS focus on the safety and performance of batteries in electric vehicles.

In addition, apart from addressing the safety aspects of batteries for electric vehicles, the BIS standards focus on the safety and performance of batteries in electric vehicles.

Amid the rising fire incidents with electric vehicles, the vehicle’s safety has become one of the major concerns. The latest fire incident is the Tata Nexon EV fire incident.
The Union Road Transport Ministry to ensure Road Traffic Safety (ISO 39001 certification), had assigned the Defence Research and Development Organization (DRDO) to investigate electric two-wheeler fire incidents. They found serious defects in the batteries in the Tata Nexon EV fire incident case.

According to the DRDO, the electric two-wheeler manufacturers may have used “low-grade materials to cut costs” that lead to the occurrence of these defects.
