On New Year's Day 2023, a fire broke out in a Tesla Megapack battery unit mounted on a trailer, used as a mobile Supercharger at a charging station in Baker, California. Witnesses, including electric vehicle owners charging at the busy holiday site, saw the mobile unit burn. According to onlookers, the fire affected roughly half of the site's 40 charging stalls, though photographic evidence suggested the physical damage was largely contained to the Megapack itself. Police tape was used to cordon off a large section of the site, including nearby permanent Superchargers, as a precaution. The cause of the fire was not disclosed publicly. It was reported as one of the first known fires involving a mobile Supercharger trailer, though stationary Megapack units have caught fire before at other sites.
Not reported. The cause of the fire had not been determined or disclosed at the time of reporting.
- Mobile battery storage units deployed temporarily at high-traffic sites should receive the same fire risk assessment and monitoring as permanent installations.
- Clear separation distances between mobile battery trailers and adjacent charging infrastructure can limit the extent of site disruption during a fire event.
- Operators should establish public incident communication protocols so causes and outcomes of battery fires can be verified and lessons shared across the industry.
