Seoul Subway Bans Large Lithium Batteries and E-Scooters Due to Fire Risks

Seoul subway passengers will be barred from carrying large lithium batteries and personal mobility devices (PMs) such as electric kickboards and e-bikes starting July 1. The Seoul Metro announced the revision of its passenger transport regulations, prohibiting the entry of PMs powered by lithium batteries and batteries exceeding 160Wh capacity into stations and trains. This strict measure aims to enhance safety following a series of fire incidents involving lithium batteries on subway services.

The ban specifically targets devices and batteries with a capacity exceeding 160Wh. This means most common items like smartphones, laptops, and standard portable power banks will not be affected, as their batteries typically fall below this threshold. The regulation, however, exempts mobility aids for passengers with disabilities, such as electric wheelchairs, ensuring continued accessibility for those who rely on them.

Recent events have underscored the risks associated with lithium batteries in confined public spaces. In September last year, smoke emanating from a passenger's electric scooter battery caused subway lines 2 and 6 to bypass Hapjeong Station. This year alone, four separate incidents involving smoke or heat generation from passengers' portable batteries have occurred. Seoul Metro cited international aviation standards for battery transport as a reference for its decision, indicating a commitment to aligning with global safety benchmarks.
