Firelion Vault charging cabinet
A charging cabinet for e-bike and power tool batteries. If a battery goes into thermal runaway, the cabinet floods with water, which stops the fire and traps the toxic fire gases. Runs on a standard wall socket.
Six separately lockable battery compartments. Batteries for six bikes fit in one cabinet.

How it works
The temperature starts to rise and the battery releases gases.
The cabinet detects the problem and cuts the charging power. The situation is monitored.
If the temperature stops rising, the cabinet stays on standby. If temperature and gas levels keep rising, it is a battery fire.
The cabinet floods with water, which stops the battery fire and traps the toxic fire gases.
Put the battery in a compartment and lock the door with a code or latch lock.
The battery charges from a standard socket, just like at home.
Gas and temperature sensors watch the compartment the whole time it charges.
Collect the full battery when you need it. No internet connection, no app.
Stop vs. slow down
Cabinets with aerosol extinguishing, and passive cabinets, buy time for rescuers, but the fire brigade is still needed to stop the reaction. According to the Finnish Emergency Services Academy’s LION research project, methods that smother the flame or displace oxygen create a risk of the gases re-igniting or exploding.
Stops the flames from spreading. Heat rises above 800 °C, toxic fire gases spread into the air and smoke into the surroundings. The fire burns out, and the premises must be evacuated and cleaned.
Puts out the visible flames but does not stop thermal runaway. Buys time for rescue work. The closed space creates a risk of explosion.
The fire goes out immediately and the reaction stops at once. There is no time for smoke damage, and the toxic fire gases dissolve into the water instead of spreading into the air.

Customer story
Vuokatti Sport Chalets 2 protected its guests, many of them athletes for whom fire gases could mean the end of a career. Instead of a separate heated bike shed, the answer was a charging cabinet.
FAQ
All batteries in the cabinet are submerged in water. That’s unfortunate, but they would be lost in a fire anyway. Our charging cabinets are built to keep people, pets and premises safe.
The cabinet has sensors inside: some measure gas levels, others temperature. Combining these signals lets us reliably detect thermal runaway or a fire and stop it at the start.
A standard socket and a large enough fuse (16 A). The extinguishing water is in a tank, so no plumbing is needed.
A large mountain bike measures over 2 m × 1.3 m × 1 m. Such a cabinet would take up several cubic metres, extinguish much more slowly and cost many times more. Batteries for six bikes fit in one cabinet, with no need for a shipping-container-sized space.
The cabinet has a master code that resets a forgotten PIN. It is unique to each cabinet, so contact whoever manages the property (often the facility manager or caretaker in companies, or the property manager in housing companies).
We’ll contact you about extending the warranty before it ends. Extending it requires us to replace the sensors, test the cabinet and run diagnostics.
Our cabinet is built to protect people from flames and fire gases by stopping the battery fire. The fire brigade is only called to remove the burnt battery.
Competing solutions, cabinets with aerosol extinguishing and passive cabinets, are built to buy time for rescuers, but the fire brigade is still needed to stop the reaction.
There are three reasons:
In a nutshell: water immersion is the most affordable, safest and most reliable way to stop thermal runaway.
