Discussion created by Toño Hernández Employee on Oct 29, 2018

Growing regulatory focus toward reducing carbon emissions while increasing the share of renewables on the grid is pushing the U.S. energy storage market size will surpass USD 4 billion by 2024 according to Global Market Insights. The electrification era demands robust Battery Management Systems (BMS). The NEWTEC-NTBMS Battery Management reference design with Functional Safety features up to ASIL-C responds to the rising needs of those e-Mobility Battery Management solutions.

 

The NEWTEC-NTBMS Battery Management reference design targets automotive applications requiring up to ISO 26262 ASIL-C or IEC 61508 SIL-2, like starter battery (with Li-Ion battery), auxiliary battery, and 12 V and up to 48 V applications; also it can be extended to support valve controllers or DC motor control designs. The industrial applications for the NTBMS reference design go from a high degree of reliability safety Medical (emergency failover systems, portable devices), Infrastructure or Decentralized Energy (battery charging stations, overcharge protection, distribute power management, smart grids), Construction & Agriculture (portable power tools, hybrid construction vehicles) to Heating & Ventilation, Transportation (e-bikes or e-scooters), and Manufacturing.

 

NTBMS

The NTBMS reference design was developed by NewTec with a two boards approach:
- a Battery Management System (BMS) application board, based on our MC33772B battery cell controller IC.
- a functional safety System-on-Module (Safety SoM) board can be used as a generic safety computer board too; it is based on our S32K144 and KEA MCUs and our FS4503C safety power system.

 

The NEWTEC-NTBMS Battery Management reference design has different safety support packages available for customers, including the necessary safety documentation and software (available at our NDA SafeAssure group) for certification purposes.
