Abstract:
Energy management in vehicles is a relevant issue, especially in the case of hybrid electric vehicle. In this paper, a global energy management for propulsion, thermal management system of a series-parallel hybrid electric vehicle is studied. An adaptive controllable thermal management system suitable for series-parallel hybrid electric vehicle is presented. According to the vehicle structure and schematic, a multi-disciplined coupled model of a series-parallel hybrid electric vehicle combined with propulsion system model and thermal management system model is proposed. The coupled model is explored with the hybrid modeling method which combines experiment modeling and theory modeling. According to the coupled model, the energy flow, distribution and heat characteristics of components are studied. Then the vehicle driving cycle simulation is explored to evaluate the validity of the relative models. Results show that the coupled simulation model can be used to analysis the mechanical,
electrical and thermal interactions between the internal combustion engine, gearboxes, electrical machines, power electronics, controlling system and so on. It also can predict the dynamic response of the series-parallel hybrid electric vehicle heat source components.
