Fundamentals of Powertrain Design for Hybrid Electric Vehicles

2020-09-01
Driven by high fuel prices, environmental regulations, and consumer demand, the market for hybrid electric vehicles (HEV) has experienced rapid growth. Every major automotive company produces an HEV. There are approximately fifty different HEV models on the market and over eight million HEVs already sold. In order to meet current and future demands in the HEV and PHEV markets, success will depend on engineering personnel knowing how to develop and manufacture HEV powertrains. This two day seminar will cover the fundamentals of HEV powertrain design.

FEA Beyond Basics Thermal Analysis

2019-12-16
Finite Element Analysis (FEA) is a powerful and well recognized tool used in the analysis of heat transfer problems. However, FEA can only analyze solid bodies and, by necessity thermal analysis with FEA is limited to conductive heat transfer. The other two types of heat transfer: convection and radiation must by approximated by boundary conditions. Modeling all three mechanisms of heat transfer without arbitrary assumption requires a combined use of FEA and Computational Fluid Dynamics (CFD).

A miniaturized and sleek protective device M. Priyanka, Mahindra&Mahindra, India D. Boobala Krishnan*, Mahindra&Mahindra, India T.Vijayan, Mahindra& Mahindra, India Keywords-Fuse, Lightweight. Research and/or Engineering Questions/Objective: Now-a-days there is lot of advancement coming in automobiles. Earlier the electronics were used in engine and engine compartment areas. Now all hydraulics and transmission have been operated by electronics. The role of electronics like sensors, actuators increasing day by day for lifting and moving operations. With increase in electronics circuit, there is complex in wiring harness and packaging space for fuse box is premium Limitations: Limitations of placing other devices. Occupy more space and weight in the vehicle. Packing constraint due to vibration and thermal management issues. Methodology: Two different fuse of same rating can be given in one fuse and we can reduce the wire size.

ELECTRIC VEHICLE THERMAL MANAGEMENT SYSTEM FOR HOT CLIMATE REGIONS Rana Tarun*, Yamamoto Yuji, Kumar Ritesh, Bhagatkar Shubhada Pranav Vikas India Private Limited, India Key Words Electric Vehicles (EV); Battery Thermal Management System (BTMS); COP; Electric Vehicle Thermal Management System (EVTMS); BTMS and HVAC System Integration; Thermal System Performance Comparison; Active Liquid Cooling; EV Battery Cooling Research and/or Engineering Questions/Objective Electric Vehicles is the need of time to limit global warming and it is in application at a wide scale in colder or mild climate regions where ambient temperature is limited to mild or moderate level. Its application (Heat pump, CO2) is constrained to cold climates only due to securing better COP for heating function, sacrificing cooling COP of the existing system when operated in Hot Climate Regions, thus limiting its application to nearly half of the automotive user-base.

Downsizing is one of the crucial activities being performed by every automotive engineering organization. The main aim is to reduce – Weight, CO2 emissions and achieve cost benefit. All this is done without any compromise on performance requirement or rather with optimization of system performance. This paper evaluate one such optimization, where-in radiator assembly with two electric fan is targeted for downsizing for small commercial vehicle application. The present two fan radiator is redesigned with thinner core and use of single fan motor assembly. The performance of the heat exchanger is tested for similar conditions back to back on vehicle and optimized to get the balanced benefit in terms of weight, cooling performance and importantly cost. This all is done without any modification in vehicle interface components except electrical connector for fan. The side members and brackets design is also simplified to achieve maximum weight reduction.
