Committee backs fire-code stricter standards for charging and storing lithium-ion batteries used in e-bikes and scooters

The committee voted Dec. 4 to amend and recommend an ordinance that would add fire-protection standards for charging and storage of lithium-ion batteries used in powered mobility devices (e-bikes, scooters, skateboards), prohibit the use of damaged or reconditioned batteries assembled from used cells, and require an informational campaign by the San Francisco Fire Department.

President Peskin said local incidents (a fatal apartment fire in 2022 and a pattern of rising incidents) motivated the legislation. Assistant Deputy Chief and Fire Marshal Ken Coughlin presented data: battery-related fires rose substantially (from 12 in 2018 to more than 58 in 2022); from 2020'2022 there was one documented death and seven injuries; in the first 11 months of 2023 there were more than 40 battery-related fires, including at least 15 inside buildings. He described the ordinance's main provisions: limit charging/storage per dwelling (three devices/batteries without additional protections); require separation and individual outlets during charging; prohibit extension cords and use of reconditioned battery packs; require larger precautions (sprinklers, rated enclosures, charging cabinets) when more than specified quantities are stored or charged; and institute a public-education campaign on safe charging and device/battery handling.

Public commenters and the committee generally supported the approach; several supervisors asked to be added as cosponsors. President Peskin moved to amend as discussed and forward the ordinance to the full Board as a committee report; the motion passed unanimously in committee.

Next steps: the ordinance, as amended, will go to the full Board. The Fire Department will develop an educational campaign to accompany implementation and the clerk will forward the ordinance to the California Building Standards Commission upon final passage.
