“…Therefore, it can be postulated that the system would work equally well with a triple threephase machine, where the three-phase windings are actually aligned in space. This has been verified for the case of three separate machines in [12]. Such a machine is believed to be closer to a standard three-phase machine and hence more likely to be used in real-world applications than the nine-phase machines with spatially shifted windings.…”

Abstract-A fully integrated on-board battery charger for electrical vehicles (EVs) has been developed recently using a nine-phase machine. All the components used for propulsion are employed in the charging process, no additional components are required, and there is no need for hardware reconfiguration between charging and propulsion modes of operation. The proposed solution can be connected directly to single-phase or three-phase grid to perform charging, so that the expensive offboard charger infrastructure is not needed. The only requirement is to use a nine-phase machine in combination with a nine-phase inverter in the powertrain of the EV. This however inevitably brings in further advantages in the propulsion mode, such as increased fault tolerance and the current subdivision into more phases. The benefits of the topology, originally developed for an induction machine, make it interesting for further investigation. Therefore, the performance of the charger is examined here using a permanent magnet synchronous machine (PMSM). The results show that the charger topology is applicable to other types of synchronous machines and is, even more importantly, independent of the angular spatial shift between the individual three-phase windings of the nine-phase machine's stator. The results are comparable with those obtained using an induction machine and confirm the viability of the solution in conjunction with the PMSM as a propulsion motor.

“…The disadvantages are that, the motors windings should be reconfigured and many switches are needed. A three-phase integrated charger based on four motors is proposed in [43]. During charging mode, one inverter and one motor are idle.…”

To avoid weight, size and cost constraints, on-board integrated charging devices use the traction system components. In this paper, the topologies of on-board integrated electric vehicles (EVs) chargers are reviewed. The topologies of on-board integrated chargers can be classified into three groups based on the integrated components. The first type is that only converter is integrated as one part of the on-board charger. While the grid side also needs filter inductors. The second group is based on the switched reluctance motor, which can integrate both the converter and the motor windings into the on-board charger. This is followed by the integrated charger based on permanent magnet motor (PM) and induction motor (IM). The last group also integrates both the converter and the motor windings. Then this paper gives a new single-phase on-board integrated charger based on AC motor. Parts of inverter are used as single-phase rectifier, parts of inverter coupled with one capacitor and inductor reconstruct an active power filter (APF) circuit, and the motor windings are used as grid-side filter inductors. As the existence of APF circuit, the proposed integrated charger can eliminate the second harmonic ripple and the quasi-Z-source network just need small capacitor and inductor to suppress ripples. Using the proposed topology, the motor can keep still in charging mode. A 2.2-kW prototype is designed to give the experimental results.Index Terms-Active power filter (APF), integrated charger, quasi-Z-source.

“…These integrated chargers are already used in two wheelers [22], fork lift trucks [23] and cars [24]. A few advancements in motor topology modifications in order to operate as a three phase PFC coupled boost rectifier are split-phase induction motor [25], special double winding machine [26], split-phase permanent magnet synchronous motor [27], split-phase permanent magnet assisted synchronous reluctance motor [28], delta-star permanent magnet synchronous motor [29], split-phase switched reluctance motor [30] and multiphase machines [31], [32]. Few examples of using topologies without.…”

As regards moving towards electrification of transportation, there is need to replace gas stations with Electric Vehicle (EV) charging stations at equally convenient locations and look at various energy storage methods onboard an electric vehicle. There are various charging methods which have been discussed in the literature. This paper discusses some new charging technology that can possibly have a tremendous impact on the future of energy storage in transportation electrification.
