Battery Management System Integrated with CAN BUS Safety Control Environment for Electric Vehicle

Battery Management System (BMS) is one of the most crucial and essential components of an Electric Vehicle. The main feature of a BMS is to safeguard the battery and make the operation reliable and smooth. To achieve the same, Battery State of Charge (SoC) evaluation, Charge Control and Cell Balancing have to be implemented in the BMS. BMS performs many complex operations that require constant optimization of the BMS for the improvement of battery life cycle, engine performance, energy enhancement and security of the vehicle. The need for security increases with the increase in the control units that favor data theft and security of the vehicle. A Controlled Area Network (CAN) based communication control system fulfills the need of a closed environment security system that optimizes the BMS and minimizes cyber threat. The main objective of this study is to give a detailed analysis of two key components of an electric vehicle viz., the BMS and the CAN bus that is used for communication. This study also covers the general model circuitry diagrams that are used to integrate the BMS and CAN bus that can be implemented in the real world. This work also hopes to help the readers who are interested in pursuing work in this field of vehicular design.
