EV CAR CAN BUS DATA

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.

该数据集包含从五家不同电动汽车（EV）制造商处采集的原始CAN总线消息。数据集的核心内容为电池相关消息，同时也涵盖其他通用车辆通信消息。这些原始CAN总线消息是电动汽车各组件间交换的基础数据，例如电池管理系统（BMS）、电机控制器及其他电子控制单元（ECU）之间的通信数据。然而，若要将这些原始消息完全解码并转换为电压、温度或荷电状态（state-of-charge）等值的人类可读格式，需借助对应的DBC（Database CAN）文件。此类DBC文件充当密钥或转换映射，用于定义原始数据的结构与含义，包括信号名称、数据缩放比例及偏移量等。遗憾的是，由于制造商限制，这些DBC文件属于专有内容，无法公开获取，因此未包含在本数据包中。该数据集对探索电动汽车电池系统的研究人员或开发者而言具有极高价值，但用户需预先获取所需DBC文件方可提取可执行的洞察信息。
