Overview
Description
Renesas' automotive wireless battery management system (BMS) offers material cost reduction and increased design flexibility, enabling more efficient scaling of electric vehicle fleets which are more competitive than traditional combustion-engine fleets.
System Benefits:
- Eliminates the traditional BMS wired harness, saving the wiring and volume for design flexibility in the battery pack and improving manufacturability without compromising range and accuracy over battery life.
- SmartBond TINY™, the world’s smallest and lowest power Bluetooth® Low Energy (LE) 5.1 system-on-chip (SoC), reduces the cost of adding Bluetooth LE in an automotive system.
- Multi-cell/Bluetooth LE with the ISL78714 automotive-grade Li-ion battery manager IC for a more cost-effective solution or 1-cell/Bluetooth LE with a Bluetooth LE MCU module for a flexible cell attachment/detachment concept.
- Supports functional safety with RH850 microcontroller (MCU) and battery management IC (BMIC) devices.
- System-level validation with a Bluetooth LE module is under development by Renesas.
