BMS Power-HiL Test System Overview

This solution brief presents the BMS Power-HiL Test System, which addresses the increasing demand for comprehensive and flexible battery management system (BMS) testing. The document outlines the significance of BMS testing during the product development stage, allowing engineers to evaluate the interaction between the BMS and other connected powertrain systems under normal and faulted conditions. It details the use of a Powered Hardware in the Loop (P-HIL) test system to emulate the functions of battery pack hardware, including voltage, current, and temperature responses. The brief also discusses application challenges such as complexity, scalability, isolation, and cost associated with traditional testing methods. Additionally, it describes the NI + Partner Solution, which leverages NI VeriStand for a flexible HIL development platform, and highlights the advantages of the DMC custom battery cell model for simulating various cell chemistries. The document emphasizes the importance of thorough testing to ensure the reliability and safety of battery management systems.
