In order to choose the best communication protocol for a Battery Management System (BMS), it is important to carefully consider a number of factors. This procedure is crucial since the selected protocol affects the system's overall effectiveness, efficacy, and cost. The five main selection criteria for protocols are examined below
A crucial component of a Battery Management System (BMS) that guarantees timely and effective communication with other systems or components in a specific application is the communication protocol.
The battery management system monitors aspects of the battery like the voltage, current, state of charge (SOC), state of health (SOH), travel range offered by the battery, battery temperature, and a host of other parameters. 2.
Some examples of systems that use CAN Bus protocols in a vehicle include: 1. Battery Management System (BMS): The battery pack of electric vehicles is the energy source that propels the vehicle forward and this battery system is in a constant state of energy transfer and needs to be monitored.
This study focuses on the development of dynamic battery models for EV applications. The models are based on the second-order ECM technique and developed using the Modelica language for four different types of Li-ion cell chemistry commonly found in commercial EVs. The thermal behavior of the battery at the cell level is also considered.
An electrochemical-thermal-capacity fade coupled model is developed to monitor the battery internal state. The dynamic programming (DP) optimization algorithm is employed to search for the suboptimal charging current profiles.
