The investigation has also revealed some acute faults in the battery management system (BMS), inferior quality cells, flaws with thermal management, and bad fuse
Back on Monday, the Defence Research and Development Organisation's (DRDO) Centre for Fire Explosive and Environment Safety submitted the investigation report in relation to the fire blast on electric scooters. During the investigation, the report showcased some serious flaws with EV batteries and it was filed to the road transport and highways ministry (MoRTH). The investigation has also revealed some acute faults in the battery management system (BMS), inferior quality cells, flaws with thermal management, and bad fuse.
The CNBC-TV18 during the first half of this month had highlighted that numerous EV firms were allegedly utilizing inferior cells quality in spite of submitting A-grade cells for testing, taking advantage of the loosely-framed rules in the absence of surprise checks. In fact, an unnamed source in Automotive Research Association of India (ARAI) has told the media that although many of the EV firms submit grade-A cells for testing, several of them might not be utilizing in all its e-scooters production and then they are also selling it in the market. The report had also highlighted issues with the battery management system used by many EV makers.
The exclusive report of CNBC-TV18 stated that the probe has also identified issues specific to each company and lapses on the part of testing agencies like the Automotive Research Association of India. (ARAI) and International Centre for Automotive Technology (ICAT) are tasked to carry out surprise checks on the manufacturers.
Moreover, the report also discovered serious flaws in identifying random samples and also it ordered all the EV firms to go through proper cells testing and at the same time, international finest procedures are followed. As per the news agency, MoRTH has shared the report with Ola, Okinawa, Jitendra EV, Pure EV, and Boom Motors and asked companies whose vehicles were involved in the recent fires to set up testing laboratories for cells. It has asked representatives of electric scooter manufacturers to submit an explanation on the report findings.
