The electric scooter fires that made news in recent weeks were caused by defects in their batteries, including in the designs of the battery packs and modules, says a report by the Defence Research & Development Organisation. A person who has seen the report told Business Standard the defects may have crept in because electric two-wheeler companies intentionally used lower-grade materials to cut costs.
