The performance and longevity of lithium-ion (Li-ion) batteries in electric vehicles (EVs) are critically dependent on effective thermal management. As internal heat generation during charge and discharge cycles can lead to uneven temperature distribution, exceeding optimal operating limits (25 - 40°C) can significantly degrade battery performance and lifespan. This study presents a performance evaluation of a novel liquid-based Battery Thermal Management System (BTMS) featuring a dual-directional coolant channel configuration designed to enhance thermal uniformity and heat dissipation. The proposed configuration combines horizontal and vertical coolant passages in an indirect cooling layout to address the limitations of conventional serpentine-type channels. A comprehensive thermal analysis was carried out under realistic loading conditions using three coolant types: water, ethylene glycol-based G48, and graphene-enhanced water nanofluids. These were evaluated for thermal conductivity

Design and Development of a Hybrid Rocket Propulsion System for Micro-Scale SAM Interceptor Missiles2026-28-0012To be published on 02/01/2026
The increasing prevalence of agile and low-signature aerial threats, such as Unmanned Aerial Vehicles (UAVs), necessitates the development of advanced and flexible air defense systems. Conventional Surface-to-Air Missiles (SAMs) at the micro-scale are often limited by short engagement times and an inability to counter saturating threats. This paper presents the conceptual design and analysis of a novel loitering interceptor missile designed to overcome these limitations. The core innovation is the synergistic integration of a throttleable hybrid rocket propulsion system with a mission-adaptive airframe featuring morphing fins. The methodology involves the theoretical design of a HTPB-based hybrid motor capable of operating in both high-thrust boost and low-thrust loiter modes. Computational Fluid Dynamics (CFD) analysis is employed to evaluate the aerodynamic performance of the missile with its fins in both stowed (high-speed) and deployed (loiter) configurations.

Microcontroller-based modular mirror for Heavy and Mid commercial vehicles2026-26-0018To be published on 01/16/2026
Existing ICE Mid and Heavy commercial vehicles in the Indian and international market are recording a large number of mishaps due to blind spots and non accessibility of the driver to the opposite side mirror in real-time driving. Non-driver side rear view mirror adjustment creates the need for the driver to get down and adjust the mirror manually/ get support from the co-passenger. The paper proposes a solution for a Microcontroller-based compact mirror adjustment system, which will run with minimal economy and highest efficiency. This will assist drivers in aesthetically and safely monitoring of mirror to check on specific blind spots in day conditions. Mirror will be actuated via a Modular control panel, a Dashboard with audio input or button-operated system based on vehicle type and customer need, along with a quick response mechanism to operate the mirror. This will reduce the prone accidents due to non-visibility by approximately 30%, ensuring enhanced road safety and driver

Oil channelization for EV transmission.2026-26-0064To be published on 01/16/2026
Leakage of oil through breathers can be a serious concern in electric vehicle (EV) transaxle units, especially due to the complexities presented by small housing space and rotational components, which are running at relatively high speed compared to conventional transmission unit. Traditional methods are mostly centred on developing individual breather compartments, resulting in excess material usage, additional weight, and increased cost of manufacturing. This paper presents a novel and compact way of oil channelization that has been created for the gearbox housing and seeks to counter oil leakage along with maximizing space and efficiency. The improved design incorporates a cover, deflector fins, and obstruction ribs together with a strategically placed oil catcher cavity that effectively keeps the breather isolated from direct exposure to oil. The larger cavity minimizes internal pressure build-up, the fins restrict oil velocity, and an exclusive return path guarantees uninterrupted

Integrated Powertrain Domain Controller Using Wide Band Gap Devices For EV Applications2026-26-0055To be published on 01/16/2026
The rapid evolution of electric vehicles (EVs) has amplified the demand for highly integrated, efficient, and intelligent powertrain architectures. In the current automotive landscape, EV powertrain systems are often composed of discrete ECUs such as the OBC, MCU, DC-DC Converter, PDU, and VCU, each operating in isolation. This fragmented approach adds wiring harness complexity, control latency, system inefficiency, and inflates costs making it harder for OEMs to scale operations, lower expenses, and accelerate time-to-market. This paper addresses the core issue of fragmented control architectures in EV powertrains by proposing an integrated domain controller-based solution for EV powertrain. The technical gap lies in the absence of a centralized intelligence capable of seamlessly managing and synchronizing the five key powertrain aggregates: OBC, MCU, DC-DC, PDU, and VCU under a unified software and hardware platform. This fragmentation leads to redundancy in computation, increased

Seals in a truck cabin is one of the major contributors for cabin noise in terms of structure borne as well as air borne noise transfer path. This study emphasizes on the effect of door seal compression prediction and its impact on structure borne NVH in trucks. Vibrations are regarded as quality criteria in the perception of customers. It is necessary to ascertain the contribution of seal stiffness on compression of the seal under closed condition of the door rather than uncompressed conditions. The dynamic stiffness of door seal is calculated by non-linear analysis. The simulations models are constructed using the Mooney - Rivlin theory for both 2D and 3D seals. This encompasses contemplating the relevant seal mounted boundary condition on the body and the door of the vehicle. The stiffness after compression of seal is extracted from this non-linear analysis which is further used to obtain the vibration modes for the doors in the truck cabin. Subsequently, the compressed seal

Acoustic Challenges in Electric Vehicles: A Comparative Study of HVAC Noise in EVs and ICE Vehicles2026-26-0353To be published on 01/16/2026
With the transition from ICE vehicles to EV’s, the dominant noise sources within the vehicle cabin have shifted from engine noise to auxiliary systems, especially HVAC systems. In conventional vehicles with internal combustion engines (ICE), engine noise tends to mask auxiliary noises. However, in electric vehicles (EVs), the lack of engine noise causes these auxiliary noises, such as those from the HVAC system, to become more prominent and potentially uncomfortable for occupants. The primary objective is to understand how the absence of engine noise in EVs influences the perceived HVAC noises. The research methodology involves static and on-road testing of both electric and ICE vehicle having common platform, conducted under similar testing conditions. The study aims to quantify and compare the acoustic characteristic differences of HVAC noise between ICEs and EVs, primarily focusing on cabin airflow noise, refrigerant flow noise, and AC compressor engagement/disengagement noise

Early Prediction of CNG Filling Time using Artificial Intelligence for Design Optimization2026-26-0662To be published on 01/16/2026
The CNG fuel system is a critical component in vehicle development and typically includes large-volume gas cylinders (up to 800 liters). As these vehicles often operate over long distances daily, frequent refueling is necessary, making a short gas filling time highly desirable. Currently, CNG filling time is evaluated after prototype development to determine the refueling duration. If the filling time is excessive, design changes to the fuel system are required, leading to significant cost and time penalties and causing delays in the vehicle product development cycle. By integrating AI/ML technology, a mathematical model has been developed based on various influencing parameters. This model will predict CNG gas filling time across all commercial vehicle platforms at the initial Zero design release gateway. This early prediction will enable further optimization to improve gas filling time. The goal of this research work to optimising the filling time for various platform before physical

More efficient drivetrain technologies are in greater demand in the two-wheeler market as a result of the introduction of BS6.2 emission standards. In order to satisfy these performance and regulatory requirements, Continuously Variable Transmission (CVT) systems—which are renowned for their stepless gear shifting and increased fuel efficiency—are being given more and more consideration. However, because CVT is nonlinear and multibody dynamic, accurately predicting its behavior is still a difficult task. With an emphasis on variables like belt slip, pulley misalignment, and transmission efficiency, this study provides a thorough multibody dynamic analysis of a belt-type CVT system used in two-wheelers. High-fidelity analysis of the belt-pulley interaction under various load and speed conditions is now possible thanks to the development of a novel modeling methodology using advanced multibody dynamics simulation software – Virtual Dynamics.

Development of Door Impact Loads Using Pedal Force Sensor and First Principles2026-26-0538To be published on 01/16/2026
The first step in designing or analyzing any structure is to understand “right” set of loads. Typically, off-road vehicles have many access doors for service/getting into cab etc. Design of these doors and their latches involve a knowledge of the closing loads when the door is shut mostly with an impact of varying magnitudes. In scenarios of these impact events, where there is sudden change of velocity within few milliseconds, produces high magnitude of loads on structures. One common way of estimating these loads using hand calculations involves evaluating the rate-of-change-of-momentum. However, this calculation needs “duration of impact”, and it is seldom known/difficult to estimate. Failing to capture duration of impact event will change load magnitudes drastically, e.g. load gets doubled if time-of-impact gets reduced from 0.2 to 0.1 seconds and subsequently fatigue life of the components in “Door-closing-event” gets reduce by ~7 times. For these problems, structures are usually

A Method of Precooling of EV Vehicle from Grid connected aux supply/Charger to reduce peak power demand of HVAC system when vehicle is allotted for passenger operation using cloud based infrastructure2026-26-0056To be published on 01/16/2026
This paper explains the method of precooling of electric vehicle from grid connected charger reduce load on HVAC and improve the range. HVAC systems are integral part of a commercial EV bus. With the rise of ambient temperatures during various seasons, the load on HVAC System is increasing. Once an Electric vehicle is released from a depot for service, with an initial soaked up ambient vehicle, the HVAC system demands peak power for cooling the interiors which consumes a lot of battery power thus affecting the range. That cause the additional energy consumption required for precooling, which cannot be estimated as it is highly dependent on ambient temperature and range of the vehicle is also dependent on HVAC consumption during summer and peak loads. This paper is proposing a method that uses a special precooling mode which is activated depending on the selection of the vehicle route based on backend application running on cloud.

Real-time Helmet Detection and Closed-Loop Enforcement System for Two-Wheelers2026-26-0650To be published on 01/16/2026
Need: In India, two-wheelers account for a significant portion of road traffic and contribute heavily to the national burden of road fatalities. Despite regulatory mandates, helmet non-compliance remains widespread due to limited enforcement reach and behavioral inertia. Currently there is no intelligent system that enforces helmet usage autonomously in a closed loop directly at the vehicle level. Motivation: The existing enforcement strategies such as traffic policing or external camera-based surveillance are reactive, infrastructure-dependent, and ineffective at scale. To overcome these limitations, we propose a real-time helmet detection and closed-loop system that is integrated into the two-wheeler itself. This approach promotes proactive safety compliance without relying on external monitoring infrastructure. Methodology: The proposed model is AI-powered, vision-based system that leverages deep learning techniques for helmet detection, supported by a custom-built dataset

3D Transient CHT Simulation of Frictional Heating in Jet-Lubricated Automotive Gears2026-26-0468To be published on 01/16/2026
Gears play a critical role in automotive transmission systems. During operation, frictional heat is generated in the intermeshing region due to loading. Effective lubrication and cooling are essential to minimize heat generation and ensure smooth operation. Lubrication failure can lead to a significant local temperature rise, potentially causing gear scuffing—a phenomenon where intermeshed gear teeth weld together and tear apart during rotation—resulting in severe damage and compromised transmission performance. To prevent this, gears are typically lubricated using splash or jet lubrication techniques. This study presents a Conjugate Heat Transfer (CHT) simulation of a jet-lubricated gear pair in an automotive transmission system to predict the local temperature rise due to frictional heating in the intermeshing region of the gears. The paper focuses on implementation of the frictional heat generation on the gear teeth and resultant transient temperature rise in the gear contact region
