Automotive Ethernet

Ethernet over a single twisted pair, now the backbone of newer vehicle networks where CAN’s bandwidth runs out. Battery systems still use CAN for control but increasingly send high-rate cell data and software updates over Ethernet.

AUTOSAR

The automotive software architecture standard that splits controller software into a standard basic layer and application components, so BMS functions can be developed and integrated like parts. Classic AUTOSAR runs on microcontrollers, Adaptive on larger processors.

DBC file

The de-facto text format, from Vector, that describes a CAN network: which messages exist, their identifiers and timing, and how each signal is packed, scaled and named. Without the BMS’s DBC a CAN log is just numbers.

LDF file

The standard file that describes a LIN cluster — its nodes, frames, signals and schedule — the LIN counterpart of a DBC file for CAN.
