Optimization of An EV Controller Design For A Three Wheeler BOVs - EMC Approach

International Centre for Automotive Technology-Nikhil Grover
  • Technical Paper
  • 2019-28-2474
To be published on 2019-11-21 by SAE International in United States
Introduction: The advent of electric mobility is changing the conventional mobility techniques and their application in automobiles across all segments. Three wheeler Battery Operated Vehicles (BoVs) are a special category of electric vehicles (EVs) as far as EMC compliance is concerned. The problem mainly lies with the open body design and cost cutting measures being exercised by the manufactures which makes Electromagnetic compatibility (EMC) compliance challenging. Objective: Though it is sometimes possible to resolve EMC malfunctions related to motor power cable, cables & wiring harness etc. using external techniques post design stage, but controller being a closed and typical element makes it difficult to improve against EMC malfunctions using external techniques. This paper would concentrate on the controller design parameters and improvement of the same in terms of Electromagnetic compatibility (EMC) and performance efficiency at the design stage itself. Methodology: This study would concentrate on designing of motor controller for three wheeler EVs, improving and optimizing the EMI/EMC aspects of the design and its performance with the following aspects in mind: 1. Selection of critical…

Sleeve, Protection, for Cable and Harness Protection

AE-8D Wire and Cable Committee
  • Aerospace Standard
  • AS60491A
  • Current
Published 2019-10-03 by SAE International in United States

Procurement specification is principally for defining protection sleeves on a cable or group of electrical/fiber optic wires (wiring bundle). Single wire protection depends on the minimum diameter of the wire. Sleeve may be used to protect a wire bundle for a platform installation or for repair of installed damaged jacket or jacket/shielded wire bundles. Refer to AS50881 for aerospace wire bundle protection installations.

Cable Construction for Machine Vision Connectivity

  • Magazine Article
  • TBMG-34882
Published 2019-08-01 by Tech Briefs Media Group in United States

Along with the onslaught of Internet of Things (IoT) and wirelessly enabled devices, cloud connectivity has become a major benefit for a range of applications from commercial to military. As of 2018, Ethernet networking surpassed Fieldbus technology in industrial settings (Figure 1). This is partly due to the growth of industrial IoT (IIoT) where the central gateway to all the sensor nodes is necessarily connected to the cloud via a hardwired Ethernet connection. In industrial settings, power over Ethernet (PoE) links can serve cameras for machine vision, to sensors for multi-modal processing capabilities. This article overviews industrial Ethernet, some of its major pain points including networking dynamics, and cable construction specific to industrial applications.

S400 Copper Media Interface Characteristics Over Extended Distances

AS-1A Avionic Networks Committee
  • Aerospace Standard
  • AS5643/1A
  • Current
Published 2019-07-09 by SAE International in United States
This SAE Aerospace Standard (AS) establishes guidelines for the use of IEEE-1394-2008 Beta (formerly IEEE-1394b) as a data bus network in military and aerospace vehicles. It encompasses the data bus cable and its interface electronics for a system utilizing S400 over copper medium over extended lengths. This document contains extensions/restrictions to “off-the-shelf” IEEE-1394 standards, and assumes that the reader already has a working knowledge of IEEE-1394. This document does not identify specific environmental requirements (electromagnetic compatibility, temperature, vibration, etc.); such requirements will be vehicle-specific and even LRU-specific. However, the hardware requirements and examples contained herein do address many of the environmental conditions that military and aerospace vehicles may experience. One should refer to the appropriate sections of MIL-STD-461E for their particular LRU, and utilize handbooks such as MIL-HDBK-454A and MIL-HDBK-5400 for guidance. This document is referred to as a “slash sheet” and accompanies the AS5643B base standard.

An Experimental Study on the Dynamic Ice Accretion Processes on Bridge Cables with Different Surface Modifications

Harbin Institute of Technology-Wenli Chen
Iowa State University-Yang Liu, Yihua Peng, Hui Hu
Published 2019-06-10 by SAE International in United States
An experimental study was conducted to investigate the dynamic ice accretion processes on bridge cables with different surface modifications (i.e., 1. Standard plain, 2. Pattern-indented surface, and 3. helical fillets). The icing experiments were performed in the unique Icing Research Tunnel available at Iowa State University (i.e., ISU-IRT). In order to reveal the transient ice accretion processes and the associated aerodynamic loadings on the different cable models under the different icing conditions (i.e., rime vs. glaze), while a high-speed imaging system was used to capture the transient details of the surface water transport and ice accretion over the cable surfaces, a high-accuracy dual-transducer force measurement system was also utilized to measure the aerodynamic loadings acting on the ice accreting cable models. It was found that the addition of surface features (i.e., pattern-indented surface vs. helical fillets) could effectively influence the dynamic ice accretion process and the final ice structures. Based on the temporally-resolved measurements of the aerodynamic drag forces acting on the different cable models, it was found that while the ice accretion on the…

Published 2019-06-07 by SAE International in United States
This specification covers 600 V heavy duty, portable, power, single and multiconductor, electrical cable for severe flexing service (see detail specifications for voltage limitations). The AS5756 insulation system has been used in aerospace ground power applications using 115/200 V (phase to neutral) at 400 Hz AC. Verification of the suitability of this product for use in other electrical system configurations (600 V, etc.) is the responsibility of the user.

Single-Photon Detector for Potential Encryption and Sensing

  • Magazine Article
  • TBMG-34600
Published 2019-06-01 by Tech Briefs Media Group in United States

Light is widely used for communications, carrying phone conversations and video signals through fiber optic cables around the world in pulses composed of many photons. Single photons are the weakest signal that can be transmitted and they have a wide range of applications including implementing an encryption technique called quantum key distribution and creating high-resolution maps. Single photons of light typically have very little energy, making them difficult to detect.
