Multi-objective optimization design and performance evaluation for plug-in hybrid electric vehicle powertrains

Electric vehicles (EVs) include battery electric vehicles (BEVs), fuel-cell vehicles (FCVs) and fuel-cell hybrid electric vehicles (FCHEVs). The performance of vehicles is usually evaluated using standardized driving cycle tests; however, the results from standardized driving cycle tests deviate from the real-world driving cycle. In order to test the adaptability of EVs to real-world driving cycles, conditions of three typical routes in Tianjin are collected and their characteristics analyzed; then BEV and FCV models are created based on a type of FCHEV to simulate 0–100 km/h acceleration and cruising performance under a real-world driving cycle; finally, a motor bench is used to test the performance of FCHEV under the NEDC (New European Driving Cycle). After the adaptability of the three models to real-world driving cycle is compared based on the simulation and test results, it is found that FCHEV can recycle braking energy and has quick dynamic response, which can be well adapted to the real-world driving cycle.

“…The cost function J fuel consists of fuel consumption, mode penalty function, and SOC penalty function; the latter two penalty functions are set to avoid frequent mode switching and maintain the balance of initial and terminal SOC, respectively. In this paper, 0-120 km/h acceleration time is selected as the evaluation index of dynamic performance [30]. In the acceleration process, it is assumed that SOC is sufficient and battery power always meets the power requirements of the MG.…”

To further improve the comprehensive operating performance of the single motor hybrid electric vehicle, a single motor hybrid powertrain configuration with dual planetary gears (SMHPC-2PG) design is proposed in this paper. By adopting a topology design method that characterizes the constraint relationship between power resource components and planetary gear (PG) nodes, all feasible configuration candidates based on the basic configuration scheme are systematically explored, and dynamic models of configuration candidates are automatically generated. The optimal fuel economy and dynamic performance for configuration candidates are simulated by applying the global optimal control strategy based on dynamic programming (DP). Results of this study demonstrate that SMHPC-2PG with excellent operating performance can be screened out by this method.

Summary In order to enhance the fuel economy of hybrid electric vehicles, this paper proposes a novel method for the design and analysis of hybrid electric vehicle powertrain configurations. Initially, by analyzing the energy transformation of hybrid electric vehicle, the single‐mode configurations are designed by considering the engine efficiency, the conversion energy loss, and the mechanical transmission efficiency, respectively. Then, two novel multimode configurations with single electric machine are obtained through integrating the single‐mode configurations. In addition, performance comparison and analysis between the two novel configurations and the improved version of Toyota Prius under Highway Fuel Economy Test and Urban Dynamometer Driving Schedule cycles are conducted. The results indicate that the two novel configurations possess better fuel economy than the improved version of Toyota Prius.
