Test of Automotive Battery Management System Control Strategies on Hardware-in-the-Loop Systems: A Low-Voltage Approach

This article introduces a model of a Battery Management System (BMS) and the comparison of the measurements between hardware in the loop (HIL) and a real vehicle. At first, an HIL has been realized to emulate a high-voltage battery, sensors, actuators, and controller area network (CAN) bus. An embedded control unit BMS has been cabled to the HIL for the execution of a closed-loop test. Finally, state of charge (SOC), state of health (SOH), Battery Cells’ Voltages, and internal resistance have been acquired and compared with real vehicle acquisitions.
