The Defence Research & Development Organisation (DRDO) that was tasked with investigating into EV fire incidents by the Union Road Transport and Highways Ministry, has found serious defects in the batteries, including designs of the battery packs and modules. According to sources in the know of the matter, these defects occur because the electric two-wheeler manufacturers like Okinawa Autotech, Pure EV, Jitendra Electric Vehicles, Ola Electric and Boom Motors may have used "lower-grade materials to cut costs".

The Centre for Fire, Explosive and Environment Safety (CFEES) at the DRDO has submitted its fact-finding report to the Ministry, as first reported by Business Standard. According to the sources, the ministry has now summoned representatives of these EV manufacturers, asking them to submit an explanation on the DRDO report findings.
