Design and modelling of optimal driveline control strategy for an electric racing car with rear in-line motors

Guo, M. January 2015 (has links)
Interest in electric vehicles (EVs) has increased rapidly over recent years from both industrial and academic viewpoints due to increasing concerns about environmental pollution and global oil usage. In the automotive sector, huge efforts have been invested in vehicle technology to improve efficiency and reduce carbon emissions with, for example, electric vehicles. Nowadays, the safety and handling of electric vehicles present new tasks for vehicle dynamics engineers due to the changes in weight distribution and vehicle architecture. This thesis focuses on one design area of the electric vehicle – torque vectoring control – with the aim of investigating the potential benefits of improved vehicle dynamics and handling for EVs. A full electric racing car kit developed by Westfield Sportcars based on an in-line motors design has been modelled in ADAMS with typical subsystems, and then simulated with computer-based kinematic and dynamic analyses. Thus, the characteristics of the suspensions and the natural frequencies of the sprung and unsprung masses were found, so that the model was validated for further simulation and investigation. Different architectures of the EVs, namely the in-line motors and the in-wheel motors, are compared using objective measurements. The objective measurements predicted with kinematics, dynamics and handling analyses confirm that the architecture of the in-line motors provides a superior dynamics performance for ride and driveability. An Optimal Driveline Control Strategy (ODCS) based on the concept of individual wheel control is designed and its performance is compared with the more common driveline used successfully in the past. The research challenge is to investigate the optimisation of the driving torque outputs to control the vehicle and provide the desired vehicle dynamics. The simulation results confirm that active yaw control is indeed achievable. The original aspects of this work include defining the characteristics and linearity of the project vehicle using a novel consideration of yaw rate gain; the design and development the Optimal Driveline Control Strategy (ODCS); the analysis and modelling the ODCS in the vehicle and the comparison of the results with conventional drivelines. The work has demonstrated that valuable performance benefits result from using optimal torque vectoring control for electric vehicle.

The implications of the rise of clean energy on lithium market dynamics

Jackson, Martin Robert January 2018 (has links)
A research report submitted to the Faculty of Engineering and the Built Environment, University of the Witwatersrand, in partial fulfillment of the requirements for the degree of Master of Science in Engineering, Johannesburg 2018 / This research aims to assess the factors surrounding the emergence of markets with the greatest potential for rechargeable lithium battery adoption. The implications of the rise of electric vehicles and electrical energy storage are measured against lithium supply and market pricing. This was resolved by reviewing all available information and comparing it with the intricacies of resources, production and recycling. An analysis of price formation is also undertaken before making assumptions to enable a forecast of future market dynamics until 2030. Electric vehicles will require almost threefold the lithium produced in 2015 by the end of the period considered, with grid storage predicted to follow suit. No geological supply constraints were found, but economic scarcity is a strong possibility. Production is highly vulnerable to disruption due to concentration and the situation is exacerbated by inelastic demand. Recycling may be the most critical means of diversifying and improving supplies. / XL2019
