The Keeper: A fire protection system for early electric vehicles

As the electric vehicle market grows rapidly, so do the safety concerns associated with fire. EV fires are inherently different from internal combustion engine vehicle fires.

Characteristics of electric vehicle fires
1. Thermal runaway
 - Fires in EV battery cells are characterized by explosive growth as heat spreads to neighboring cells.
 - If initial fire suppression fails, the temperature rises rapidly and there is a high risk of the fire spreading to a large scale.
2. Increased fire duration
 - Lithium-ion batteries produce their own oxygen due to chemical reactions, which can cause the fire to continue burning.
 - It is difficult to completely extinguish the fire with ordinary fire extinguishing equipment.
3. Complex fire suppression process
 - Electric vehicle fires involve high temperatures, toxic gases, and electrical hazards, making them difficult for firefighters to access and extinguish.

Features of The Keeper
1. Lower sprinklers
 - Lower sprinklers spray water directly onto the vehicle battery pack to delay thermal runaway and contain the initial temperature rise.
2. Automated and real-time fire detection
 - The detection module detects fire quickly and operates automatically to respond to the initial fire immediately.
 - It ensures golden time and prevents the spread of fire to a large fire.
3. Easy to deploy and cost-effective
 - It can be installed without additional construction on the existing parking infrastructure, and maintenance and initial adoption costs are economical.
