Design for battery management system hardware-in-loop test platform

This article introduces a Hardware-In-Loop test platform for Battery Management System (BMS). At first, hardware is designed and arranged to simulate input and output signals of BMS. Then models for vehicle, battery and hardware driver are built in Simulink and downloaded to xPC Target to form a real-time system that interacts with BMS. Based on xPC Target real-time system, all the hardware and software are integrated to set up Hardware-In-Loop test platform for BMS. This test platform is able to simulate a real battery at different driving conditions to realize functionality and reliability tests.
