Introducing RAD-wBMS – Wireless Battery Management System Monitoring Solution

May 30, 2022

Intrepid Control Systems in collaboration with Analog Devices (ADI) have created a state-of-the-art battery cell measurement and network testing tool for supporting OEMs and Tier 1s when implementing wBMS (Wireless Battery Management System®) technology into EV battery pack designs.

“The wBMS technology draws on two important fields: sensing & measurement and RF communications. The wBMS technology is a complete solution that is easy for the automotive manufacturer to integrate into a battery pack design. It includes a wireless cell monitoring controller (wCMC) unit for each battery module, and a wireless manager unit to control the communications network, which connects multiple battery modules wirelessly to the ECU.” from Analog Devices

RAD-wBMS offers engineers several features and advantages including:
1. Ability to read and decode of all the wBMS data wirelessly
 – e.g. Cell or total voltages, temperature and computation results (SoC, SoH, SoP)
2. Ability to display Network Metadata for system integrity confirmation
3. Applicable Use cases:
  – Battery test cell data collection
  – Battery Pack assembly and production inventory data collection
   – CAN-BUS gateway of the wBMS data to other network ECUs or for independent data logging (e.g. ICS cloud-based data logging hardware and software solutions)
