Overview
Description
This 20-28 cell battery pack for domestic generators features Renesas’ multi-cell, single-IC battery manager in a daisy-chain configuration, ensuring safe and effective battery life monitoring. It integrates cost-optimized system control from the RA family of 32-bit Arm® Cortex®-M MCUs, allowing for scalable battery-pack designs that manage various voltages and interface safely with diverse load devices.
System Benefits:
- Highly integrated BMS IC reduces part count and system cost.
- Core BMS design can be scaled to accommodate a large pack voltage range (42V to 118V), reducing development time for different pack sizes.
- Bluetooth connectivity can be easily added via the Pmod™ interface
