Overview of multi-machine drive systems for electric and hybrid electric vehicles

Abstract

This paper presents an overview of multi-machine drive systems for electric vehicles (EVs) and hybrid electric vehicles (HEVs), with a particular focus placed on the different system architectures and their key technologies. Some typical configuration topologies such as two-machine system for HEV, wheel drive system, multi-motor drive systems and compoundstructure integrated machines system are investigated in this paper. Some fundamental technologies for multi-machine drive systems are discussed, with emphasis on machine structures, operation modes, and control strategies. Then, comparisons are made among various multi-machine drive systems and a new multi-machine drive system topology is reported, namely the modular cascade machines (MCM) drive system. Keywords: multi-machine drive systems; electric vehicle (EV); hybrid EV (HEV); modular cascade machines (MCM)I.

Hardware Architecture and Configuration Parameters of a Low Weight Electronic Differential for Light Electric Vehicles with Two Independent Wheel Drive to Minimize Slippage

“…In a moving vehicle that is tracing a curve to the right of radius 'R' and angle 'θ' (in degrees) the distance travelled by each wheel in that curve ('X') is as described in Equations (1) and (2) (using the subscript 'L' to refer to the wheel on the left and 'R' for the unit placed on the right) being 'd' the The final architecture of the ED developed, based on two (master/slave) open-source electronics platform Arduino One SMD R3 boards, is presented in Figure 4 (schematic) and Figure 5 (physical hardware implementation). These diagrams and pictures include all the basic elements described in the literature [13,14] along with all the sensors listed in the previous chapter. An exhaustive evaluation test is proposed including different paths driven at low and high speeds that generate different slipping conditions in the drive train wheels due to the concentration of excessive torque either in the left or right wheels.…”

Performance Evaluation of Hybrid Electric Vehicles for Sustainable Transport System

“…The ICE is driven by conventional fuel and the storage battery provide the energy to the electric motor drive. These two prime movers can work together or separately using different possible topologies namely series, parallel, series- parallel or complex topology [10][11][12][13][14][15]. The control methodology for each topology is different but the complete emphasis is to increase the fuel efficiency while fulfilling the traction demand of speed and torque throughout the driving cycle.The performance analysis of series and parallel topology along with conventional vehicle is done for different driving cycle and comparison is done using ADVISOR software [6,13], so that the torque and speed demand of the vehicle can be optimized and the total efficiency and emissions of each vehicle can be determined [13].…”
