NXP Battery Management Software Development Kit and Toolchain

BMS-SW

NXP offers a comprehensive suite of software solutions for battery management systems (BMS), including production-grade device drivers, safety libraries (SL), application examples, real-time drivers and development tools. Together with a complete hardware toolkit, we enable customers to save development time and costs by using our International Organization for Standardization (ISO) 26262 and automotive Software Process Improvement and Capability Determination (SPICE) level 2/3 compliant software for AUTomotive Open System ARchitecture (AUTOSAR) and non-AUTOSAR environments.

Features

BMS Driver Package

  • Production-ready complex device drivers (CDD) for NXP BMS silicon parts, with Serial Peripheral Interface (SPI) driver of Microcontroller Abstraction Layer (MCAL)
  • CDD interface layer to abstract complexity of the device drivers
  • Device-specific CDD examples
  • Developed according to ISO 26262 and ASPICE
  • Tested on S32K3, portable to non-NXP MCUs
  • Configurable with EB tresos Studio™ or NXP S32 Design Studio for both AUTOSAR™ and non-AUTOSAR use

BMS Safety Libraries (SL)

  • SL implement the safety mechanisms defined in the BMS device safety manuals
  • Allowing BMS application software components (SWC) to perform safety checks and access monitoring data from the battery cell controller (BCC) units
  • Developed according to ISO 26262 and ASPICE level 2/3
  • Tested on S32K3, portable to non-NXP MCUs
  • Configurable with Elektrobit tresos Studio or NXP S32 Design Studio

BMS Chipset Middleware

  • Reference (example) implementation of the BMS Chipset interfacing logic
  • It handles error checking, data formatting and timing
  • Include libraries, drivers and configuration files

Application SW Components

  • Reference (example) integration and SW components for BMS function and safety, communication and diagnostics
  • Developed and tested on HVBMS (Automotive) and BESS1.0 (Industrial) reference designs

MCU Abstraction Layer

  • Real-Time Drivers (RTD): comprehensive suite of configurable drivers for S32K3 microcontroller units (MCUs) for use as MCAL in AUTOSAR or in non-AUTOSAR architectures
  • SAF: Safety Software Framework and structural core self-test (SCST) for S32K3
  • Example integration is available for both AUTOSAR and non-AUTOSAR environments

BMS SW Development Tools

  • Eval graphical user interface (GUI): Easy-to-use product evaluation tool to learn and demonstrate the functionalities of NXP BMS products
  • Script GUI: Test tool to evaluate device features under specific use cases, custom scripts and custom hardware (HW) boards
  • Transformer Physical Layer (TPL) Decoder: Monitoring and decoding tool for NXP proprietary TPL protocol

Supported Devices
