Overview

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

Applications

  • Large powered motors (Chainsaws/HVAC)
  • Home/Solar backup systems
  • Light electric vehicles (LEV)
