Industrial battery management module reference design for 20S applications

High cell count battery (>15s) systems are increasingly used in industrial applications. These applications are more cost-sensitive and require a simple solution that can include monitoring, protection and control functions, and even SOC (state of charge) information, rather than just basic independent hardware protection. This reference design provides the platform for a complete battery pack side solution. Contains all independent hardware protection functions of the bq76930, and implements a reliable communication interface for the host device to read battery information.

characteristic

• ● Supports 16- to 20-cell battery applications
• ● Inherit all independent hardware protection functions from bq76930
• ● Can detect whether the charger is plugged in
• ● Can detect whether the load is removed
• ● Unique, isolated CAN PHY communicates with host system
• ● Supports UART communication with external host at up to 128k baud rate
