automotive battery management systems

Infineon Technologies solutions help engineers to develop dependable automotive battery management systems (BMS). Neutron Controls, preferred design house for Infineon, has now announced its ECU8™ system platform which enables accelerated development of BMS based on Infineon chipsets. With this offering, Neutron Controls and its design services clients, can significantly reduce development effort by having a full hardware and software platform solution for a battery management unit built on a robust ASIL-D, ISO26262 foundation.

The ECU8 energy control unit includes Neutron Control’s proprietary microcontroller module featuring the AURIX™ TC3xx and TC4xx, TLF35584 Hypersonic PMIC, TLE9015 ISO UART Transceiver, and TLE9012 ISO UART Battery Interface Card. ECU8 is the latest addition to Neutron Control’s Rapid Engineering Development (RED) platform family, a collection of versatile platforms designed to accelerate software development, prototyping, and product development.

The ECU8 platform is compatible with lithium-ion battery cells, monitoring up to 12 cells individually per module. By combining up to 20 modules, the platform supports up to 1000 V batteries. Available communication interfaces of the ECU8 include iso-UART and iso-SPI for Ring Mode, dual Ethernet ports and triple CAN-FD ports. It also provides high-side and low-side drivers for external contactors. From the software perspective, low-level drivers are implemented for the various components for the AURIX TC3x TriCore™ architecture. In addition, calculations for state-of-charge (SoC) and state-of-health (SoH) can be integrated.
