Multi-cell Li-Ion batt management system

Posted: 10 Jan 2011     Print Version  Bookmark and Share

Keywords:MSP430  battery management system  bq76PL536 

This application report explains the implementation of a multi-cell lithium-ion battery management system using an MSP430 MCU and the bq76PL536. The battery manager is implemented using the standard evaluation boards for the MSP430 MCU and the bq76PL536.

The bq76PL536 can be stacked vertically to monitor up to 192 cells without additional isolation components between ICs. A high-speed serial peripheral interface bus operates between each bq76PL536 and the MSP430 microcontroller to provide reliable communications through a high-voltage battery cell stack. The battery management system can communicate with an external host or battery charger using USB communication or asynchronous serial communication such as RS232 or RS485.

This application report demonstrates the following features: passive cell balancing, cell undervoltage monitor, cell overvoltage monitor, safety cell overvoltage monitor, cell overtemperature monitor. It also detects whether the battery system is in charge or discharge mode by detecting changes of cell voltages.
