Off-highway and heavy duty vehicles systems consist of heterogeneous system elements. Development of scalable electrification architectures for such vehicles requires deep understanding of operating loads, duty cycles and careful consideration of complex system interfaces of electrified subsystems and functions both the vehicle and its attachments. This paper explains some of the techniques to perform detailed analysis of electrification architectures using design structure matrices, network analysis, clustering methods and reliance on simulations for electrification architecture synthesis. One example of series hybrid architecture will be discussed in detail covering the critical aspects of architecture development, analysis and synthesis in this paper.

Electrification has a significant potential to lower greenhouse and other harmful vehicle emissions as well as reduce fuel consumption. However, the development of such powertrains for the Indian market pose unique technical and commercial challenges, broadly due to the inherent system complexity, relatively lower product maturity and thus higher cost. This paper demonstrates that a deeper consideration and interaction of single powertrain components, combined with a holistic approach to powertrain system optimization, enables the achievement of future CO2 and consumption targets, with a highly modular powertrain family at significantly lower costs. Consequently, the key to successful hybrid powertrain solutions is reduction of complexity on the component level and optimization of the functional interactions between key components at the powertrain level.

The vector controlled induction machine drive with field weakening capability is a preferred choice for traction applications. The parameters of the machine have a significant influence on the performance of the drive. The maximum torque output in the field weakening region is limited by the leakage inductances of the machine. Therefore, while selecting a machine for a traction application, it must be ensured that the leakages are such that the required torque speed characteristics are well satisfied in the field weakening region up to the maximum speed. This paper analyses the effect of leakage inductance on the performance of the induction machine drive in the field weakening region. The critical value of leakage inductance which ensures operation up to the highest application speed with specified load demand is derived. The effect of leakage inductance in field weakening region is studied using Matlab/Simulink. The field weakening algorithm is experimentally validated on a 30 kW induction machine, up to five times the base speed.

A seven degrees of freedom (DOF) mathematical model of a three wheeled vehicle (TW V) with one front wheel and two rear wheels is developed using MATLAB software. The model consists of different subsystems i.e. Wheels system, longitudinal and lateral dynamics and suspension system. The dynamic model is simulated and validated for circular and impulse input test. A permanent magnet synchronous in-wheel motor called hub motor model is developed and integrated with TWV to develop three wheeled hub motor vehicle (TWHV) for simulating the effect of hub motor on vehicle stability. PID controller developed to control the vehicle speed with Hub motor. The TWHV model with PID controller is helpful for developing controller algorithms to enhance handling characteristics and to develop three wheeled electric vehicles with hub-motors

Roll-over stability of a ground vehicle is often considered as an important safety factor for maneuvering of vehicle in curved trajectories. This paper deals with investigating the path of the vehicle collected from planner algorithms and generate a mathematical model depicting the speed such that the vehicle maneuvers within the safe drive envelope. The roll-over dynamic stability of the vehicle is derived by application of the forces at the vehicle CG and performing its rigid body analysis. The simulation results are based on the critical speed plot derived from rigid body model. The same model is expected to be used for controlling the vehicle speed during the curvature.

Electric vehicles are coming into fame in recent times in many of the countries as there is zero tail-pipe emissions. In line with this Indian government plans to migrate to full electric vehicles by 2030 in order to reduce the environmental pollution caused by existing conventional internal combustion engines. Currently lithium-ion battery is widely used as energy source in electric vehicles and hence many of the domestic and international OEMs started their aggressive research in the field of battery. It is known that battery needs to be operated at defined operating temperature range for maximum performance and hence battery thermal management plays a vital role. In this work, thermal management strategies with different geometrical cell arrangements for a battery pack consisting of 18650 format LiNiMnCo cylindrical cells are studied using Ansys FLUENT for natural convection and forced convection conditions. Studies showed that air cooling with fan placed at the top side of the box maintains uniform temperature distribution across the battery pack irrespective of the cell arrangement.

This paper is an application of ISO 26262 functional safety standards for the proper design, development and validation of Lithium ion battery system. Lithium ion battery plays very important role in Electrification of the vehicle. It has capability of high discharge currents and better energy density compared to more traditional NiMH batteries. With these capabilities, batteries have safety hazards like high risk of fire, explosion, heat, smoke. Battery management system (electronic unit) can reduce the risk by controlling the intrinsic parameters or functionality of battery to avoid safety hazards. There are several standards typically considered for safety and construction of battery pack, but it do not address the risk of electronic malfunction of the battery controller or vehicle system. ISO 26262 process and concept can be applied to bridge this gap and ensure the system safety of plug-in vehicles equipped with large-scale battery packs. In this paper, lithium ion battery system integration and validation aspects are covered to achieve functional safety. It also covers key components of ISO 26262, and qualification of hardware and software of batteries. It covers fail safe methodologies for design of battery system for electric and hybrid vehicles and validation of Lithium ion battery system.

Lithium-ion batteries with high energy density are considered as one of the prime energy source while considering electric mobility application. This paper investigates three types of lithium ion cell conditions which are new, operational and damaged cells. Morphology and composition analysis of cathode, anode and separator of each cell is studied by Scanning Electron Microscopy (SEM) Technique. Phase identification of anode and cathode of each cell is also studied by X-Ray Diffraction (XRD) technique. It is observed that grain size and structure changes with each of the three types and different phases are observed at cathode and anode of each battery. Characterization of cell by SEM and XRD techniques are found to be effective for detailed material study of various cells.

Large-scale deployment and integration of renewable energy sources (RES) such as wind turbine generators and photovoltaics are important in a Hybrid Microgrid (HMG) environment, an immense challenge considering their intermittent power generation. Energy storage resources play a vital role in enhancing intermittency issues in RES and when integrated into a HMG, also enable other benefits, such as power quality improvement, short-term power supply, ancillary service and arbitrage [1]. However, economics of large-scale energy storage systems (ESS) are high considering their present status of technology maturity [2]. A trade-off on optimal sizing of ESS to the cost of its implementation in a HMG is imperative for its successful operation. This paper presents a thorough analysis on appropriate HMG architecture design based on location and load requirements, optimal sizing of ESS resources and ESS characteristics in serving various degree of power needs. In addition, thorough sensitivity analysis on component sizing in HMG environment is performed and knowledge gained from the simulation studies is utilized to propose a control philosophy for the operation of battery energy storage in HMG.
