Summary: An adjustable dc-link operation is proposed for electric vehicles using a dual-port inverter (DPI) with an internal dc-dc conversion system. Unlike conventional two-stage structures, the DPI provides a direct power flowpath from the battery to the inverter, reducing power processed by the dc-dc converter and improving efficiency. Two operation modes and modulation strategies are investigated to fully exploit the inverter's potential in high-speed and low-speed range, with a two-stage modulation strategy proposed to minimize power processed by the dc-dc converter and improve overall efficiency of the system.

Summary: This article proposes an effective stepwise nontransient method to protect the safety of the vehicle's drive system in case of fatal faults in the electric vehicle's powertrain system with high motor speed by entering and exiting the active short circuit (ASC) of permanent magnet synchronous motor (PMSM). The method utilizes a two-phase short circuit as a transition step before entering and exiting the three-phase ASC, effectively suppressing transient current and overshoot voltage. The experimental results from a 15 kW PMSM test platform verify the effectiveness of the method.

Summary: This study introduces a decentralized management concept for urban charging hubs, where electric vehicles can access multiple charger clusters controlled by aggregators. The provided day ahead schedules and peak power limits of the aggregators can restrict energy supply. A suitable energy management concept is required to mitigate the impact on EV users. In the proposed approach, an electromobility operator allocates incoming EVs into charger clusters using a smart routing algorithm that optimizes cluster allocations and charging schedules. Real-time charging control is achieved through an optimization problem solved by each aggregator. The results demonstrate the effectiveness of the proposed concept in reducing deviations from schedules and violations of power limits, while decreasing unfulfilled charging demand and unscheduled discharge from EV batteries.

Summary: This paper proposes a novel in-wheel motor (IWM) driving system driven by two permanent magnet synchronous disc motors (PMSDMs) with a planetary differential gear train (PDGT).
