A low-profile, remotely operated platform (“skateboard”) is designed to enhance firefighter safety and effectiveness when responding to electric vehicle (EV) battery fires and thermal runaway events.

The device is connected to a standard fire hose and can be remotely maneuvered underneath a vehicle, positioning it directly below the battery pack. Once in position, three hardened, hollow lances extend vertically to penetrate the underside of the battery enclosure.

After penetration, the two outer lances retract, leaving the center lance in place. High-pressure water is then delivered through the center lance directly into the battery pack. The injected water is forced through the internal structure of the battery, exiting through the openings created by the outer lances as well as existing vent pathways. This promotes internal cooling and helps suppress thermal runaway more effectively than external water application.
