Automotive qualified SimpleLink™ wireless MCU for use in wireless battery management systems

Overview

TopologyBattery Management System
IC revisionE1

Description

This reference design provides a 52s Wireless Battery Management Unit (wBMU) for energy storage systems with high cell-voltage accuracy. The wBMU passes voltage and temperature data from each cell to the host controller in real time, using wireless communication technology. The design overcomes challenges in wired battery management system (BMS) architecture by avoiding cumbersome manufacturing processes, reducing frequent maintenance needs, and minimizing failure rates of connectors and harnesses. Wireless communication reduces the number of required cables and connectors, lowering system weight and cost.

Features

  • ±2.4mV voltage accuracy at 2V < cell voltage < 4V, –40°C to 125°C without calibration
  • Full cell temperature sensing with multiplexer (MUX)
  • Robust wireless communication with functional safety-rated protocol
  • Robust and programmable battery cell and pack protection
  • 32μA current consumption in keep-alive mode
  • Compatible with bus bar or no bus bar connection

Typical applications

  • Wireless battery management system (BMS)
