Standard EV Battery Management System

Overview

Description

This complete automotive battery management system (BMS) is designed for up to 70 series-connected Li-ion cells. The MCU and multi-cell Li-ion battery management devices monitor cell voltage, pack temperature, and current, detect faults, and control cell balancing.

System Benefits:

  • Delivers superior BMS accuracy with 2mV precision and six sigma long-term drift (LTD), enhancing driving range and battery life.
  • Offers low BOM cost and optimized FuSa, EMI/EMC, and hot plug design, reducing R&D effort. Compatible with the RH850 automotive MCU family, which includes dedicated drivers and BMS software.
  • Accelerates ASIL software development with a complex device driver (CDD) that manages BMS measurements and functional safety (FuSa) features.
  • Ensures functional safety up to ASIL D and includes advanced security features.
  • Features an intelligent power device for external load control.
