Electric Vehicle Fire Prevention System
Physical System / Product
We propose a system that detects precursors and prevents thermal runaway, responding before the rapid increase in temperature and therefore reducing the amount of coolant required to extinguish the fire.
Acting Before the Thermal Runaway
Before the thermal runaway is initiated, the temperature is significantly lower than after it is initiated, requiring less coolant.
Amount of Coolant Required
According to the experimental data obtained from the National Fire Research Institute of Korea, 15kg of carbon dioxide can prevent a thermal runaway from being initiated.
How do we detect precursors?
We use the Battery Management System (BMS) to monitor abnormalities in the battery
System Preview
-
The BMS detects precursors of a thermal runaway.
2. Our software utilizes accumulated data to confirm a thermal runaway.
3. Once confirmed, coolant is injected into battery modules through integrated pipes.
4. Notifications are sent to nearby fire departments and the vehicle owner.

Quick Response
If overheating occurs while passengers are inside the vehicle, an immediate notification is sent to alert them. This prompt response allows passengers to evacuate safely and avoid potential harm.
Extinguish Completely
In situations where thermal runaway is not completely terminated, notifications are sent to the nearest fire station. This is rapid alert system is crucial as EV fires require quick response and specialized firefighting expertise.
Real Time Battery Monitor
A mobile application on the user's phone allows real-time monitoring the battery's condition.
Data on battery temperature, voltage, and physical impact is recorded and collected.
Code for Data Analysis
This Python script can analyze historical data collected during previous EV fire incidents using an Isolation Forest algorithm. Then, it evaluates new inputs for thermal runaway risks by detecting anomalies and confirms whether the precursors of a thermal runaway are present.
