High performance MCU for an EV/HEV battery management system reference design

A system example for an active cell balancing battery management system. The TMS570LS0432 microcontroller commands EMB1402 EVM to monitor the battery cells and perform charge/discharge from one battery cell to an external 12V supply. The user can view the cell status and control cell balancing from a GUI running on the host PC.

Features:

• The diagnostic features of TMS570LS0432 MCU are enabled to monitor and report TMS570LS0432 status during runtime
• The TMS570LS0432 MCU configures BQ76PL455A for monitoring cell voltages and checking BQ76PL455A status during runtime
• The TMS570LS0432 MCU analyzes the data from all cells and generate active cell balancing command
• The TMS570LS0432 MCU commands EMB1428 for cell balancing and monitor EMB1428 and EMB1499 status during runtime
• The TMS570LS0432 MCU communicates with host PC via a UART emulated by the NHET module to display the status and control the balancing operation during runtime
