Development of Duty Cycle for Transmission System Components in a Two-Wheeled Electric Vehicle2024-26-031801/16/2024
A two-wheeler is exposed to various dynamic loads transferred from roads and input given by the vehicle prime mover, which leads to the occurrence of torque on the wheel and transmission. The torque generated depends on the terrain and riding pattern of users, so it becomes important to develop a duty cycle of transmission considering multiple events enabling us to understand the durability standard of the component designed. The tests performed were on an EV two-wheeler that uses a belt drive transmission. The paper will focus on the following aspects, which cover the customization of the torque cell for the pulley system in the transmission, followed by the testing on different selected terrain conditions and analysis methodology for generating the duty cycle for different systems in transmission of the vehicle. A customized torque cell using strain gauges was developed with locations identified from finite element analysis performed on the wheel pulley. Strain gauge locations are

Challenges for Indian Road Traffic with Sound Alert Devices on Electric Vehicles2024-26-021101/16/2024
Challenges for Indian Road Traffic with Sound Alert Devices on Electric Vehicles For safety towards pedestrians and other road-vehicles, sound alert systems (horns) have been in use since development of Automobiles. On the same line but with special purpose of preventing a Driver to sleep in a running vehicle, a Driver Monitoring System [DMS] is recently developed. For Electric Vehicles which are very quiet during starting and driving till 20 km/hr, Acoustic Vehicle Alert System (AVAS) is deployed in Europe and likely to be implemented in India soon. For all these Alert Devices, there are Standard Regulations across the world: ECE R-28 for Horns and ECE R-138 for AVAS. They, however, define only lower and upper dBA limits of the sound radiated by them. For DMS, no such regulation exists till today. With this, there has been a long time debate on what an optimal dBA level should be there, for all road-users as well as for vehicle- users inside the cabin. It would be adequate, on one

Dual-Motor-BEV Controls Optimization2024-26-024301/16/2024
In this paper we will discuss different techniques of controls optimization for a dual motor BEV model and look at the most optimal solution with an objective to minimize motor losses or maximize efficiency. In a dual motor model, torque split ratio plays a vital role in deciding the operating points for each motor and hence the losses or inefficiency in the system. It is important to find the optimal torque split ratio to improve range and performance. Four techniques covered in this paper includes ECMS (Equivalent Consumption Minimization Strategy, DP (Dynamic Programming), DOE (Design of Experiment) and Empirical relation-based approach. ECMS is a local optimization technique whereas DP is global optimization technique. DOE was used to perform a full factorial analysis with an eventual goal of creating a map which relates TSR (Torque Split Ratio) to the operating points in the form of vehicle acceleration and vehicle speed. A quadratic empirical relation between vehicle acceleration

Influence of Rear Suspension Local Stiffness on Full vehicle Ride & handling Performance2024-26-006101/16/2024
One of the biggest challenges for automotive industry is with respect to material saving and to have control on cost of development and still meeting performance in each aspect. Stringent weight targets help industries to have good margin on component costs. In recent times we have seen vehicle underbody contribution to total vehicle is significant in range of 12% to 18%. Total weight directly impacts the range of electric vehicle which is a key metric for success from real-world usage point of view and customer appeal. Hence control on suspension and frame design for light weighting is prominent trend in industry, this leads to deterioration of suspension compliance as well as vehicle ride and handling performance. Sub-frame and knuckle play crucial role in definition of overall suspension stiffness. Present Study focusses on electric vehicle rear cradle design for weight saving with minimum reduction of stiffness. Understanding compliance which obtained from frame\cradle in vehicle

Electric Vehicle charging Interruptions2024-26-013701/16/2024
This paper presents, an analysis of different kind of technical issues encountered while charging electric vehicle using plug-in charger. The electric vehicles is charged periodically, based on charging system configuration and requirements set by the vehicle. However, in certain instances, vehicle charging was interrupted and does not charge the battery completely. Therefore, condition of the itineraries get affected due to interruption of charging. To deal with such situation it is required to upgrade the charging process. Using logged vehicle measurement data, we analyzed the problem and updated the software and hardware in vehicle. The root cause of analysis showed how charging is interrupted and vehicle remains idle while coupler is still engaged. In this method, we identified different reasons of interruptions - mistaken communication while charging, power supply(Charger) failure, short protection, component leakage, charging facilities. This analysis were very useful in deriving

A Comparison of Wire Bonding vs. Spot Welding vs. Soldering in the Prevention of Thermal Runaway in a Battery Pack2024-26-010901/16/2024
EVs are a fast-growing market and appear as a promising option against the high emission of gasoline and diesel vehicles. The growth in the EV market has been decent and a regular buyer is still skeptical due to fire incidents occurring with EVs. Complex electronics, improper thermal management, mechanical abuse, improper cell grading activities and control in production, lack of testing in a production plant, and of course, uneven degradation of cells can be one of the reasons this promising technology is facing thermal runaway and in turn, the wrath of the government and public alike. One of the reasons thermal runaway can be triggered after a cell catches fire is because a part of heat travels via busbars to the neighboring cells, as the busbars can conduct heat faster than the air. For the heat that is conducted, it is easily understandable that we need to break the electrical, as well as thermal conduction connection to the neighboring cells. This paper presents a comparison of

A Traffic Microsimulation Based Study of an Electric Road System with Dynamic Wireless Power Transfer2024-26-010201/16/2024
Electrification of road transport is a critical step towards establishment of a sustainable transport ecosystem. However, a major hindrance to electric mobility is the high cost and weight of the battery pack. Downsizing the battery pack will not only address these issues, but will also reduce embedded emissions due to battery manufacturing. One approach towards reducing battery pack size and still offering the user of electric vehicles similar mobility experiences as in case of conventional vehicles is to set up extensive network of charging or battery swapping stations. Another approach is to provide the vehicle with required energy while it is on the move. However, conventional systems such as overhead line or conducting rails have several disadvantages in the urban environment. One solution that has come up in this regard in recent times is the concept of Electric Roads System (ERS), which involves dynamic wireless power transfer (DWPT) to the vehicles from power transmitters
