The package consists of several main detailed models: internal combustion engine (ICE), motor, continuously variable transmission (CVT), battery, energy management system (EMS) etc . Each component is built as a library, and can be connected together according to the parallel HEM's topology. Simulation results, such as ICE power demand, motor power demand, battery instantaneous state of charge (SOC), pollution emissions etc. are given and discussed.
