7.14.1. Overview

The Metis Thermal Event Detection Unit Driver component interfaces with the Metis thermal event detection unit sensors to monitor gas concentrations and detect potential thermal runaway events in the high voltage battery pack.

7.14.2. Functions

	Title	Description
1	Initialize Metis Thermal Event Detection Unit	Initializes communication with the Metis thermal event detection unit and configures the sensors based on the provided parameters.
2	Read Gas Sensor Values	Reads the current gas concentration values from the configured Metis sensors and provides the data to other components.
3	Detect Thermal Events	Monitors the gas concentration values over time and detects potential thermal runaway events, triggering appropriate actions.
4	Perform Sensor Diagnostics	Runs periodic diagnostic checks on the Metis sensors to detect any faults or communication issues.
