Power Losses Minimization for Optimal Operating Maps in Power-Split HEVs: A Case Study on the Chevrolet Volt

Abstract: The power-split architecture is the most promising hybrid electric powertrain. However, a real advantage in energy saving while maintaining high performance can be achieved only by the implementation of a proper energy management strategy. This requires an optimized functional design before and a comprehensive analysis of the powertrain losses after, which could be rather challenging owing to the constructive complexity of the power-split transmission, especially for multi-mode architecture with multiple plane… Show more

“…A typical efficiency map of a motor/generator unit for automotive applications is shown in Figure 3 . Even higher peak values above 0.94, up to 0.95 and 0.97, are proposed in ref., [14,15] Castellano and Cammalleri [ 16 ] or Jurkovic, Rahman, Patel, and Savagian. [ 17 ] A proper design would deliver the peak efficiency around the point of more common steady operation of the motor/generator in the specific vehicle.…”

“…Depending on the driving conditions, this configuration allows for various operating modes such as pure electric mode, series hybrid mode, and parallel hybrid mode according to power distribution [9,13,17,20,[24][25][26]. It offers advantages such as improved fuel efficiency, performance, and reduced emissions by providing more flexibility in power management and optimization under different driving conditions [14,[27][28][29].

“…Nonetheless, the high constructive complexity of power-split transmissions requires proper mathematical tools for the analysis and the design. Castellano and Cammalleri [7], taking the Voltec multimode power-split transmission as a case study, described a procedure to evaluate a global efficiency map in various battery scenarios that can be exploited to extract data to implement a real-time EMS. The contribution is based on a universal parametric approach that can be applied to any power-split transmission.…”
