7.12.1. Overview

The Hv Thermal Runaway Detection Controller component detects thermal runaway events in the high voltage battery pack using data from thermal event detection unit (TEDU) gas sensors. It processes the sensor data and determines if a thermal runaway event has occurred in any of the battery modules. The component provides status of the thermal runaway detection to other components.

7.12.2. Functions

	Title	Description
1	Process TEDU Sensor Data	Processes the data received from the thermal event detection unit gas sensors to detect thermal runaway events in the battery modules.
2	Determine Thermal Runaway Event Status	Determines the overall status of thermal runaway detection based on processed sensor data. Provides status (no event detected, high risk, event detected) to other components.
