The drivetrain components of an electric vehicle can be utilized to obtain an on-board battery charger (OBC) to save cost, volume and weight. Many integrated OBC topologies have been proposed in the past years, which involve a wide range of machine types, inverter topologies, and power levels. None of these ideas provide a universally acceptable alternative due to the disadvantages they inherit. Therefore, "drivetrain integrated on-board chargers" is still an interesting research topic.In this paper a single-phase, zero-torque integrated on-board charger control method, which utilizes the machine inductance very effectively and requires minimal intrusion to an existing drivetrain design with a 3-phase permanent-magnet synchronous machine and a three-phase inverter for plug-in hybrid and electric vehicles is investigated.

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.

“…The biggest advantage of this propulsion system architecture is its modularity. Standardized battery units with integrated dcdc converters, the so-called smart battery, can be stacked to provide a desired power and energy rating [12], [14]. Thereby, different drive trains can be realized using the same components which results in lower costs due to the economy of scale [5].…”

“…In contrast to the battery, the inverter and electric machine can be operated most efficiently at an adjustable dc-link voltage with the aid of dc-to-dc converters [5,] [11], [12]. This is because the switching losses of the inverter can be significantly reduced by dynamic adjustment of the dc-link voltage as function of speed of the machine, which enables lower PWM switching frequencies, lower noise and even transition into six-step operation [13].…”

Abstract-The objective of this paper is to provide an overview of emerging technologies for modular power converter architectures for electric vehicles. Nowadays, the most common electrical drive-train architecture exhibits one single inverter which is directly tied to the battery. As a consequence, only one high-voltage battery module can be applied and the dc-link voltage of the inverter and its apparent power rating is directly dependent on the available battery voltage. To overcome this restriction, modern power converter architectures with a higher degree of freedom have been proposed. These architectures exhibit modular dc-dc converters to allow different battery technologies to be linked to drive inverters operating independently from each other. To make this development feasible, new components and technologies are evolving which enhance the efficiency over mission cycles while ensuring further integration of the power-converter architectures.Wide-bandgap power semiconductors enable high switching frequencies and miniaturization of passive devices. Smart topology enhancements and control methods allow a significant loss reduction, in particular at light loads, resulting in a higher efficiency of the drive train over the entire driving cycle. Highly integrated bidirectional battery charger systems with intelligent charging strategies inhibit battery degradation and provide opportunities for grid stabilization. It is demonstrated how these technologies are realized and implemented to contribute to the development of future electric vehicles.
