“…Large volume and weight are not good news for vehicle applications. An integrated starter/generator (ISG) uses one machine, as shown in Figure 16, and has been a trend in the automotive industry [54,55]. Since the rotor of the ISG directly connects to the ICE crankshaft and the maximum speed of the ICE can reach more than 6000 r/min, the ISG has to work at a very high speed as a generator.…”

Abstract:The paper presents a number of advanced solutions on electric machines and machine-based systems for the powertrain of electric vehicles (EVs). Two types of systems are considered, namely the drive systems designated to the EV propulsion and the power split devices utilized in the popular series-parallel hybrid electric vehicle architecture. After reviewing the main requirements for the electric drive systems, the paper illustrates advanced electric machine topologies, including a stator permanent magnet (stator-PM) motor, a hybrid-excitation motor, a flux memory motor and a redundant motor structure. Then, it illustrates advanced electric drive systems, such as the magnetic-geared in-wheel drive and the integrated starter generator (ISG). Finally, three machine-based implementations of the power split devices are expounded, built up around the dual-rotor PM machine, the dual-stator PM brushless machine and the magnetic-geared dual-rotor machine. As a conclusion, the development trends in the field of electric machines and machine-based systems for EVs are summarized.

“…The values of L12, L13 and L23 are deduced as shown in Equation (1): Based on the equivalent model in Figure 5c, the mathematical models of active power exchanged among three energy ports can be expressed in the following equations: P P P P P P P P P (3) where ω = 2πf and f is the switching frequency. 12 is the shifted-phase angle between port 1 and port 2, 13 is the shifted-phase angle between port 1 and port 3, and 32 is the shifted-phase angle between port 2 and port 3, respectively.…”

Three-port isolated (TPI) bidirectional DC/DC converters have three energy ports and offer advantages of large voltage gain, galvanic isolation ability and high power density. For this reason this kind of converters are suitable to connect different energy sources and loads in electric and hybrid vehicles. The purpose of this paper is to propose chaotic modulation and the related control scheme for TPI bidirectional DC/DC converters, in such a way that the switching harmonic peaks can be suppressed in spectrum and the conducted electromagnetic interference (EMI) is reduced. Two chaotic modulation strategies, namely the continuously chaotic modulation and the discretely chaotic modulation are presented. These two chaotic modulation strategies are applied for TPI bidirectional DC/DC converters with shifted-phase angle based control and phase-shifted PWM control. Both simulation and experiments are given to verify the validity of the proposed chaotic modulation-based control schemes.

“…However, conventional EVs rely merely on the battery as the sole power source, thus, these types of EVs can only be used for short duration trips and are not practical for normal daily usage [4,5]. To extend the range for normal applications, the range-extended EV (RE-EV) which also incorporates an internal combustion engine (ICE) as secondary source has been proposed [6][7][8][9].…”

Abstract:A new magnetless axial-flux doubly-salient DC-field (AF-DSDC) machine is proposed and implemented into the application of a range-extended electric vehicle (RE-EV). By employing the radial active part for the torque production, the proposed machine can produce satisfactory torque density to fulfill the requirements of the RE-EV system. With the support of the 3D finite element method (3D-FEM), the performances of the proposed machine are calculated and compared with the requirements of the typical passenger RE-EV applications. To offer a more comprehensive illustration, the common radial-flux (RF) machines are included for comparison.
