Abstract 

This dataset comprises raw CAN bus messages collected from five different EV car manufacturers. The primary focus of the dataset is on battery-related messages, although it also includes other general car communication messages. These raw CAN bus messages represent the fundamental data exchanged between various components of the electric vehicle, such as the battery management system (BMS), motor controller, and other electronic control units (ECUs). However, to fully decode and interpret these raw messages into human-readable formats such as voltage, temperature, or state-of-charge values, corresponding DBC (Database CAN) files are required. These DBC files serve as a key or translation map that defines the structure and meaning of the raw data, including signal names, data scaling, and offsets. Unfortunately, these DBC files are proprietary and are not publicly available due to manufacturer restrictions, and hence, they are not included in this data package. The dataset is invaluable for researchers or developers looking to explore EV battery systems but requires the user to have prior access to the necessary DBC files to extract actionable insights.

Instructions: 

The zip file contains five separate TXT files, each containing raw CAN bus data collected from different EV car manufacturers. The structure and format of the data vary across the files, reflecting differences in the manufacturers’ data protocols. The files do not include any manufacturer-specific information or identifiers, meaning the data is presented as plain, unprocessed messages without metadata or contextual details. Each file exclusively holds raw CAN bus messages, requiring external resources like DBC files to decode and interpret the data. This package is purely a collection of raw, unstructured data for further analysis or research.
