SummaryThis paper introduces an alternative control strategy for the variable voltage control of an electric drivetrain for a Class 4 medium-duty delivery truck and compares the resulting vehicle energy consumption over standardized drive cycles. The baseline system, S1, uses a standard electric drivetrain without a DC-DC and a battery at 460 V. The proposed system, S2, contains a DC-DC converter and a lower voltage battery with three voltage options being investigated: 200 V, 230 V, and 300 V. Previous work has shown that using a bi-directional DC-DC converter, the Fixed Target Modulation Index (FTMI) of the power electronics can be optimized in order to reduce the energy consumption across a drive cycle. In this study an Adjustable Target Modulation Index (ATMI) is proposed, which combines the best aspects of the fixed target modulation index control to attempt to improve efficiency even further. The new control strategy is shown to improve the energy consumption by up to 2.34% over a vehicle with a conventional electric drivetrain, depending on the required drive cycle.

“…1) which operate permanent magnet motors could obtain higher efficiencies in the low RPM region when a DC-DC converter is added to the system between the battery and the inverter (Fig. 2) [2,3,4,5,22,23]. The DC-DC converter gives the designer freedom to vary the DC bus voltage and operate the overall system more efficiently.…”

“…The Toyota Prius, one of the most well-known hybrid vehicles, uses a DC-DC converter to boost the battery voltage from a 200 V battery to a 500 V DC bus, which is shared between the main inverter and the generator's inverter. In addition to greater controllability, the torque-speed envelope of the motor can be expanded when the inverter is operated at a higher DC voltage [13][14][15][16].…”

This paper is focused on modeling and analysis of 3 and 4 branch epicyclic transmission systems for Hybrid Electrical Vehicles (HEVs) using the matrix method and transmission systems analysis (TSA) tool. The TSA tool is especially developed to analyse such systems. The application of the system to a typical hybrid electric vehicle driveline is modeled and a comparison of the performance characteristics of competing designs is discussed. In addition, the potential benefits of the 4 branch epicyclic system are presented.
