Hardware-in-the-loop simulation on a hybrid power system

A hardware-in-the-loop simulation(HILS) platform for a hybrid power system is designed and researched. Based on CAN network and xPC-Target real-time simulation, a distributed real-time HIL simulation platform is established. More details about the platform including the scheme design, the data acquisition system, the interface, the simulation software, the electronic load, the CAN communication protocol are presented. With a Ultracapacitor in the loop, a backward simulation on the hybrid power system are carried out respectively on this platform. It is verified that the hybrid power system design has great advantages on the optimization of battery's working conditions which would be useful to extend the battery's lifespan. Also, the platform designed in this paper meets the real-time simulation requirements effectively and provides a method for more complicated simulation on electric vehicles.
