VUB in collaboration with VDL and IFPEN, developed a multi-objective energy management strategy for long-distance electrified heavy-duty vehicles, which is generic in nature and could be easily transferred onto changing multi-modal drivetrain configurations.
Apart from efficient propulsion, onboard energy buffer sustenance and respecting component operating limits, the proposed energy management supports other important mission objectives such as effective usage of future plug-in charging opportunities, maximizing battery-electric operation in zero urban emission zones and pollution control through EATS temperature regulation. This is achieved by integrating a-priori route information from previously developed LONGRUN eco-routing and eco-driving activities.
The proposed energy management strategy is well-integrated into a multi-level energy management framework which will be implemented in real-time through a hierarchical network of subsystem ECUs, a hybrid control unit and a cloud-based mission planner. Detailed simulations of an HD plug-in series hybrid electric coach have been used to analyse the effectiveness of this approach on VECTO coach and real-world Paris-Rouen driving profiles, including a range of future plug-in charging opportunities and in-city zero emission zone lengths.
Further details about the activity can be found in the conference article “Integrated multi-objective energy management of a long-haul plug-in hybrid electric coach” (https://researchportal.vub.be/en/publications/integrated-multi-objective-energy-management-of-a-long-haul-plug-).
