Abstract

This paper proposes a system that utilizes the Micro Controller Unit to detect and effectively respond to thermal runaway events that may occur during electric vehicle battery charging. Thermal runaway refers to a rapid fire hazard caused by the increase in internal battery temperature, which can be particularly catastrophic in indoor charging environments. The proposed system is equipped with real-time temperature sensors and communication modules to monitor battery temperature changes. When a fire is detected, the system automatically moves the battery to a fire suppression area to extinguish the fire. Finally, a prototype was developed, and the system's functionality was verified through simulations of fire scenarios.
