“…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.…”

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.

“…Table 1 summarizes some typical specifications of the electric drive systems, i.e., the commercial Prius and Protean Electric drive systems [32][33][34], the radial-flux PM hub machine developed by Rix and Kamper [35], and the direct-drive machine investigated in this paper. The 2004 Prius uses a high-speed machine with an additional gear box, so the number of poles is relatively low.…”

This paper presents a five-phase fault-tolerant permanent-magnet synchronous machine (PMSM) used for electric vehicles. In multiphase fault-tolerant PMSMs equipped with fractional-slot concentrated windings, excessive magneto-motive force (MMF) harmonics can lead to thermal demagnetization of the permanent magnets (PMs). In order to reduce the lower-order harmonics, the origins of the 2-pole harmonic in conventional winding configurations are investigated, and an unequal-turn winding configuration is applied to cancel the lower-order harmonics. The main electromagnetic performances of the unequal-turn winding configuration are investigated and compared with conventional winding topologies. Based on the principle of maintaining constant instantaneous power, the fault-tolerant control strategies for open-circuits of up to two phases are developed. All of the investigations are verified by finite element analysis (FEA) results.

“…A complete efficiency map can be then determined and integrated in the vehicle simulator. To validate the relevance of the results given by the EMTool, a comparison with an experimental efficiency map of the Toyota Prius II electric motor [12] is presented from Figure 4 to Figure 6 with the repartition of the error between simulation and experimental results on the whole operating conditions. Efficiency maps have a mean difference of 5% and a maximum of 17% in highly saturated regimes (saturation phenomena are not taken into account in EMTool for the moment).…”

Plugin Hybrid Electric Vehicles (PHEVs) have demonstrated the potential to provide significant fuel displacement across a wide range of driving cycles. Companies and research organizations are involved in numerous research activities related to PHEVs. One of the current unknown is the impact of driving conditions and standard test procedure on the true benefits of PHEVs from a worldwide perspective. To address this issue, Argonne National Laboratory (ANL) and IFP Energies nouvelles (IFPEN) have partnered under the IEA Annex XV task to evaluate the market specificities between Europe and U.S. Four different PHEV powertrain configurations with four All Electric Range will be analyzed under different standards (i.e., NEDC, UDDS, HWFET) and real world drive cycles (i.e. ARTEMIS…). The impact of different driving behavior for Europe and the US market will be analyzed through component sizing, fuel consumption benefits as well as Green House Gases (GHGs) considering the electricity production mix.The study will provide insight on how PHEVs can be designed to support worldwide market introduction of a limited number of vehicle options to maximize market penetration.
