When electric vehicle fires strike in confined spaces, every second counts. Our Smallest EV Fire Robot is engineered to tackle the critical challenge of lithium-ion battery thermal runaway where traditional fire apparatus simply cannot reach. Weighing only 50kg with dimensions of just 78cm×48cm×21cm, this portable firefighting robot delivers powerful fire suppression in underground parking garages, multi-level charging stations, and tight vehicle storage areas. With up to 16 hours of endurance, 0.8 MPa water mist spray pressure, IP65 waterproof rating, and a 200-meter remote control range, you get immediate response capability backed by fourobot's 10 years of manufacturing excellence and CE/ISO/TAF/TELEC certifications.

Electric vehicle fires pose unique dangers.
Battery thermal runaway generates extreme heat exceeding 1,000°C.
Traditional firefighting methods struggle with access and safety.
Your fire crews face toxic hydrofluoric acid gas exposure. High-voltage electrical hazards threaten responders. Confined spaces like basement parking levels restrict conventional equipment deployment.
That's where our portable Smallest EV Fire Robot changes everything.
This fire robot for EV fires enters spaces where humans cannot safely operate. It navigates narrow aisles between parked vehicles. The low-profile design fits under ceiling clearances as low as standard parking structures. Your team controls the unit from a safe distance while the robot delivers continuous cooling directly to the battery source.
The lightweight construction means two firefighters can deploy it within minutes. No heavy lifting equipment required. No exposure to explosive risks. Just rapid, effective fire suppression exactly where you need it.

Ultra-Compact Design for Restricted Access
Your robot navigates where fire trucks cannot enter. The 21cm height profile slips under low ceilings. The 48cm width moves through standard doorways and between parked vehicles. You gain access to underground facilities, automated storage systems, and vehicle transport decks.
Self-Cooling System for Sustained Operation
The integrated self-cooling mechanism keeps internal components stable during extended firefighting operations. This allows continuous deployment without overheating concerns. Your unit maintains performance even in high-temperature environments.
All-Terrain Flame-Resistant Tracks
Rubber crawler tracks provide superior traction on wet, oily, or debris-covered surfaces. The robot climbs stairs and slopes up to 40 degrees. It crosses obstacles up to 100mm high. You get reliable mobility regardless of ground conditions.
Safe Remote Operation
Control the unit from up to 200 meters away. Your firefighters stay clear of toxic gas clouds, explosion zones, and thermal radiation. The remote system delivers responsive, intuitive control even in low-visibility conditions.
IP65 Water-Resistant Construction
Complete protection against water jets and dust ingress. Your robot operates in wet environments, under active sprinkler systems, and through foam applications without component damage.
Optional Otter-X Cooling Module
Enhance suppression capability with the detachable EV cooling module. This attachment delivers targeted cooling agents including water mist or potassium oxide extinguisher directly to battery compartments. The specialized nozzle creates 2-4μm POE gas particles for maximum penetration into battery cells.
Underground Parking Structures
Multi-level basements with low ceiling clearance present access challenges. Our fire robot navigates ramps, turns tight corners, and identifies specific vehicles in thermal runaway. You deliver cooling agents to the exact location without exposing personnel to basement fire conditions.
Automated Vehicle Storage Facilities
High-density automated parking systems stack vehicles in tight configurations. Traditional firefighting cannot reach interior storage positions. The compact robot enters narrow aisles between automated racks. It provides continuous cooling before fire spreads to adjacent vehicles.
Maritime Vehicle Transport
Car ferries and Ro-Ro vessels pack vehicles in cramped deck configurations. Smoke density and space constraints make manual firefighting extremely dangerous. Your robot moves between tightly arranged vehicles to deliver sustained battery cooling while crew remains at safe standoff distance.
EV Charging Stations
Commercial charging hubs concentrate multiple EVs in covered structures. A single battery failure risks cascading thermal events. Rapid robot deployment contains the initial fire while preventing spread to neighboring vehicles during charging operations.

Q:How long does the battery last during active firefighting operations?
A:Your robot operates continuously for 2 hours while towing hose and actively spraying. In standby mode without water flow, the battery provides up to 16 hours of endurance. This gives you extended deployment capability for monitoring and repositioning between suppression cycles.
Q:Can the robot withstand corrosive gases from lithium-ion fires?
A:Yes. The chassis and sensor housings feature anti-corrosive coatings that resist hydrofluoric acid gas—a common toxic byproduct of EV battery fires. The flame-resistant rubber tracks and IP65-rated seals protect internal components from chemical exposure.
Q:What is the maximum control range in underground environments?
A:In open line-of-sight conditions, you can control the robot from up to 200 meters. In concrete structures like basement parking, signal penetration naturally reduces range. The system maintains reliable control in most underground facilities. For extended-range operations in particularly challenging environments, signal repeaters are available.
Q:Does operating the robot require specialized training?
A:The intuitive remote control uses familiar joystick operation. Most fire crew members achieve operational proficiency within 4-8 hours of training. The servo motor system provides smooth, predictable movement. Your team can focus on tactics rather than complex equipment operation.
Q:How do we recover the robot if it loses power in a hot zone?
A:The robot includes a neutral-gear manual release mechanism. This allows the unit to be pulled or winched without motor resistance. A heavy-duty recovery eyelet on the chassis provides a secure attachment point for extraction using standard fire service rope or cable systems.
Q:Can we use foam or other extinguishing agents instead of water?
A:The standard configuration delivers water through the self-cooling system. The optional Otter-X module accommodates potassium oxide extinguisher (POE). For foam or other specialized agents, our ODM service can adapt the spray system. Contact our technical team to discuss your specific requirements.
Q:How does the water mist system improve cooling effectiveness?
A:The 60μm particle size creates a fine mist that maximizes surface contact with hot battery components. This microscopic droplet dispersion absorbs more heat per liter than solid water streams. The 0.8 MPa pressure ensures penetration into battery pack enclosures where cooling is most critical.
Q:Is the robot suitable for indoor warehouse fires with narrow aisles?
A:Absolutely. The 48cm width and in-place turning capability make the robot ideal for warehouse environments. It navigates standard pallet rack aisles and turns in confined spaces where traditional equipment cannot maneuver. The low ground clearance handles typical warehouse floor conditions including expansion joints and cable covers.
