The Hardware-In-The-Loop (HIL) setup provides a platform to test the design of an estimation or control algorithm with a battery plant model. The plant model is downloaded to a real physical hardware simulator and the estimation/control algorithm is hosted on an embedded controller. Physical hardware components and connections such as sensors, actuators, physical wiring interconnections are a part of this test. The HIL simulation is a standard practice followed test the Electronic Control Units (ECUs) before production. The general framework of a HIL test for battery systems, as shown in the figure below, consists of:
i. a simulator (dSPACE Scalexio) hosting the battery plant model,
ii. an embedded controller (dSPACE MicroAutoBox-II) hosting the estimation or control algorithm, and
iii. a Graphical User Interface (dSPACE ControlDesk) to monitor and visualize the test results.
