20-28 Cell Battery Pack (Up to 118V)

This solution is designed for a 20-28 cells battery management system (BMS) aimed at domestic battery-powered generators. The design uses Renesas’ multi-cell, single-IC battery manager in parallel to safely and effectively monitor battery life, as well as cost-optimized system control from the RA family of 32-bit MCUs. This combination creates a system for a battery-pack board capable of managing higher voltages and interfacing with a wide variety of load devices.

System Benefits​:

• A complete large voltage (40V to 118V) self-contained BMS
• System health checks/charge measurements
• External communication port (RS-485)
• Design is capable of passing common safety regulations
