“…The auxiliary battery can be bypassed, producing a zero-voltage vector in its connected converter (S7-S12), and it can also be charged from the traction battery while the electric machine is being powered, provided the converter connected to the traction battery (S1-S6) has enough voltage margin to produce the desired torque in the machine and to charge the auxiliary battery. In 2018, S. Semsar et al proposed a similar system, as shown in Figure 17a [35]. This system is capable of charging both batteries from a single-phase ac power grid (terminals a, n), using an additional diode full-bridge single-phase ac-dc converter (D1-D4) and a contactor (K1) that should be closed in battery charging mode.…”

Electric vehicles (EVs) contain two main power electronics systems, namely, the traction system and the battery charging system, which are not used simultaneously since traction occurs when the EV is travelling and battery charging when the EV is parked. By taking advantage of this interchangeability, a single set of power converters that can perform the functions of both traction and battery charging can be assembled, classified in the literature as integrated battery chargers (IBCs). Several IBC topologies have been proposed in the literature, and the aim of this paper is to present a literature review of IBCs for EVs. In order to better organize the information presented in this paper, the analyzed topologies are divided into classical IBCs, IBCs for switched reluctance machines (SRMs), IBCs with galvanic isolation, IBCs based on multiple traction converters and IBCs based on multiphase machines. A comparison between all these IBCs is subsequently presented, based on both requirements and possible functionalities.

“…The other is that the impedance and the turn number of primary windings for the magnetic combination transformer should be identical. Another open-end winding integrated charger system needs only an additional uncontrolled diode-rectifier to charge the battery [55]. No additional switches are used.…”

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.

“…However, this system required an additional on-board EVBC. In 2018 [204], a similar solution capable of charging both batteries simultaneously from a single-phase ac electrical grid was proposed, being necessary to add a diode-bridge rectifier to interface the electrical grid. A more complex solution comprising galvanic isolation was proposed in 2016 [205] for interfacing a three-phase ac electrical grid, using a diode bridge rectifier and a full-bridge inverter per phase to connect with each of the three primary windings of a magnetic combination transformer, with the only secondary winding being connected to a diode bridge rectifier which, in turn, was followed by the EV battery.…”
