Special Issue Information

Dear Colleagues,

Electric vehicles (EVs) are becoming more and more attractive and competitive for road transportation, in response to global warming and increasingly serious environmental pollution. All related technologies of EVs, such as motor driving and battery charging, have attracted extensive attention in both industrial and academic fields. It is well-acknowledged that the main barriers for further development and popularity of EVs are two-fold: limited battery capacity and long charging duration.

A novel idea for designing the electric system of EVs has come up due to the concept of electric-drive-reconstructed onboard charger (EDROC). Under the concept, the high-power drivetrain of an EV can perform functions of both driving and charging, and the charging power is only limited by the drivetrain rating. In this way, the needs of additional onboard module for slow charging and expensive off-board infrastructure for fast charging are eliminated, almost without impacts on the cost, the weight and the volume of EV.

It is clear that advances in EDROC will contribute to the development of EVs. Thus, this Special Issue invites original papers exploring the latest technologies, emerging topologies and effective control strategies for EDROCs. Authors are also encouraged to submit review papers to summarize the state-of-the-art advances in the field and to provide valuable guidance for future research directions.

This paper presents a new electric drive-reconfigured on-board charger and initial electromagnetic torque suppression method. This proposed reconfigured on-board charger does not need many components added to the original electric drive system: only a connector is needed, which is easy to add. Specifically, the inverter for propulsion is reconfigured as a buck chopper and a conduction path to match the reconfigured windings. Two of the machine phase windings serve as inductors, while the third phase winding is reutilized as a common-mode inductor. In addition, the initial charging torque is generated at the outset of the charging process, which may cause an instant shock or even rotational movement. In order to prevent vehicle movement, the reason for the charging torque and suppression method were analyzed. Further, predictive control of the model based on mutual inductance analysis was adopted, where the charging torque was directly used as a control object in the cost function. Finally, experimental performances were applied to verify the proposed reconfigured on-board charger under constant current and constant voltage charging. Full article

The idea of electric-drive-reconstructed onboard charger (EDROC) systems, along with the concept of dual-channel charging, offers a novel design, thought to enhance the integration and fault tolerance of the charging system of electric vehicles (EVs). This article investigates a dual-channel EDROC incorporating an asymmetrical six-phase permanent magnet synchronous machine (ASPMSM). A unique operation mode, called the unbalanced charging voltage operation mode, exists in this topology, in case the voltages of the two batteries are unequal. This unbalance results in different winding currents following through two channels, leading to an undesired charging torque in the machine. To ensure the safety of the system, an effective charging torque elimination method, based on dual-channel winding current balance, is proposed, which achieves a dot-shaped current path of torque generation-associated subspace (i.e., α–β subspace) by balancing the dual-channel charging power. Eventually, a controller is designed for the system and a prototype is created, to validate the effectiveness of the proposed method. Full article
