## ZASS MANTIS (Battery Monitor(DISPLAY) and Logger)

STM32 based display and control unit designed for ZASS Lithium Battery Packs.

The system reads battery telemetry data via FDCAN/RS485 and visualizes it on a DWIN HMI screen using UART communication.

## Features

• Displays Cell Voltages, Total Pack Voltage, SOC, and Temperature.
• **2x FDCAN** and **1x RS485** ports for communication.
• **UART** implementation for DWIN display driver.
• Detailed fault monitoring (Over-Voltage, Under-Voltage, Over-Temp, Over-Curr).
• Detailed log saving into SD Card included all data that comes from pack.

## Communication Flow

•   **BMS -> MANTIS (FDCAN/RS485):** Receiving raw battery data.
•   **MANTIS -> DISPLAY (UART/FDCAN):** Parsing data and updating screen variables.
