It includes dedicated PC-based software for real-time viewing and analysis of the charge, cell-balance and fuel gauge processes. The application can be used as a complete battery pack management system for notebooks, medical and industrial equipment, and other, similar applications.
MSP430 System Solutions This application report explains the implementation of a multi-cell lithium-ion battery management system using an MSP430TM microcontroller and the bq76PL536. The battery manager is implemented using the standard evaluation boards for the MSP430 MCU and the bq76PL536.
You can upgrade algorithms with the latest charge, cell-balance, or fuel gauge technologies with a firmware change. This system uses its own COM-based protocol for communication between the battery pack management system and the host device. You can implement the SMBus protocol in the PSoC firmware, if desired.
The battery management software is continuously checking for a fail conditions on the battery pack; it samples the cell voltages and the integrity of the battery pack every second. The system goes to low-power mode if there are not any corrective actions or pending tasks. A brief description of this process is shown in Figure 2.
The switch on transistors Q6 and Q7 allow the power supply to be disconnected from the LOAD to protect the battery from deep discharge. This switch is optional and can be removed to reduce total device cost. Often, deep discharge protection is implemented in the batteries themselves by means of a dedicated protection IC.
In multi-cell battery packs, balancing is critical because tiny differences in cell properties can cause certain cells to charge or discharge quicker than others, resulting in imbalances. These imbalances can degrade the overall capacity and performance of the battery pack over time and, in extreme circumstances, harm the cells.
