Abstract : Availability of diverse methods or algorithms to implement the basic battery management system (BMS) functionalities make it a challenging task to choose the best that suits a vehicular feature requirement. This paper focuses on the development of a simulator tool for a software BMS model which incorporates the functionality and implementation approach selected by the user via a user interface. The major functionalities such as state of charge and state of health estimation, cell balancing, and cell protection are implemented using basic algorithms. The model is interfaced to a user interface that enable parameter initialization from the user's end, along with the display of simulation results. MATLAB tools Simulink and App Designer are used for BMS modelling and user interface design, respectively. The user interface has the provision to export simulation results to excel and view the outputs as graph. The work can be extended to include more algorithms and functionalities, and hardware interfaces for development of the simulator into a full­ fledged teaching–learning and system-in-loop tool.
