Sprinklers & Targeted Battery Cooling in EV Parking Areas
Building sprinkler protection and targeted EV battery cooling address different objectives and should be integrated with detection, isolation and response planning.
Building Protection and Battery Risk Are Separate Layers
A car-park sprinkler system is a fundamental active protection layer that helps limit fire growth and exposure to adjacent vehicles and the structure. The EV battery pack, however, is located beneath the vehicle and thermal-runaway intervention requires additional operational and technical consideration.
Issues to Be Considered Together
- Sprinkler system and water supply
- Smoke control and alarm integration
- Emergency shutdown of charging equipment
- Vehicle and fire-service access
- Operating procedure for targeted battery-cooling equipment where provided
- Post-fire vehicle quarantine and monitoring
Targeted Cooling
Where under-vehicle or battery-pack-specific intervention equipment is planned, access geometry, flow rate, operating procedure and tested conditions of use should be clearly defined.
