PMD fires often the result of battery short circuits: Experts
SINGAPORE - Personal mobility devices (PMDs) that catch fire usually do so because of batteries that have short-circuited, said experts The Sunday Times spoke to. Associate Professor Palani Balaya from the department of mechanical engineering at the National University of Singapore (NUS) told ST that using batteries from an unreliable source, overcharging PMDs, or using an incompatible charger are some reasons why lithium-ion batteries in PMDs can short-circuit. Another issue is when PMDs do not meet safety standards, said experts. There have been a significant number of fires related to non-compliant PMDs which do not have the compulsory UL2272 certificate. In 2019, there were 102 fires caused by non-compliant PMDs - almost double the 52 in 2018. Last year, Mr Lam Pin Min, then Senior Minister of State for Transport, said it was worrying some people had started using non-compliant PMDs during the circuit breaker. The Government banned electric scooters from footpaths in November 2019, following a spate of accidents related to PMDs. Since the ban, the e-scooter population here has shrunk significantly, from a peak of about 100,000 in November 2019, to just 8,500 in March this year....
