Overview

Renesas' automotive wireless battery management system (BMS) eliminates wire harnesses allowing for flexible battery placement, simplifying the development of scalable electric vehicles.

System Benefits:

  • Eliminates the traditional wire harnesses required in a BMS, saving weight and space while improving flexibility
  • Easier battery replacement and reuse throughout the life cycle
  • Renesas’ low power Bluetooth® Low Energy (LE) 5.1 device*1 for wireless BMS is ideal for battery life cycle standardization based on the open Bluetooth LE standard, instead of a proprietary wireless protocol unique to a single supplier
  • Single-cell/Bluetooth LE with a Bluetooth LE MCU module for a flexible cell attachment/detachment concept
  • A system-level functional safety concept for the wireless BMS is under preparation

*1: DA14531 is industrial grade. Automotive grade product is under development.
