  • Comparison of Tab-To-Busbar Ultrasonic Joints for Electric Vehicle Li-Ion Battery Applications
    Article Comparison of Tab-To-Busbar Ultrasonic Joints for Electric Vehicle Li-Ion Battery Applications Abhishek Das * , Anup Barai, Iain Masters and David Williams WMG, The University of Warwick, Coventry CV4 7AL, UK; [email protected] (A.B.); [email protected] (I.M.); [email protected] (D.W.) * Correspondence: [email protected]; Tel.: +44-247-657-3742 Received: 26 June 2019; Accepted: 12 September 2019; Published: 14 September 2019 Abstract: Recent uptake in the use of lithium-ion battery packs within electric vehicles has drawn significant attention to the selection of busbar material and corresponding thickness, which are usually based on mechanical, electrical and thermal characteristics of the welded joints, material availability and cost. To determine joint behaviour corresponding to critical-to-quality criteria, this study uses one of the widely used joining technologies, ultrasonic metal welding (UMW), to produce tab-to-busbar joints using copper and aluminium busbars of varying thicknesses. Joints for electrical and thermal characterisation were selected based on the satisfactory mechanical strength determined from the T-peel tests. Electrical contact resistance and corresponding temperature rise at the joints were compared for different tab-to-busbar joints by passing current through the joints. The average resistance or temperature increase from the 0.3 mm Al tab was 0.6 times higher than the 0.3 mm Cu[Ni] tab, irrespective of busbar selection. Keywords: electric vehicle; thin metal film; ultrasonic metal welding; electrical resistance; temperature rise 1. Introduction Lithium-ion (Li-ion) electrochemistry-based secondary batteries are now widely used for electrification of automotive vehicles due to several advantages, including high energy density, low self-discharge and portability [1,2].

  • A System Level Approach to the Design and Analysis of PCB
    ABSTRACT ABERG, BRYCE. An Approach for the Design and Analysis of PCB Busbars in High Power SiC Inverters using FEA Tools. (Under the direction of Iqbal Husain). Wide band gap semiconductors, including silicon carbide (SiC) and gallium nitride (GaN), allow engineers to develop higher power density systems compared to traditional Si technology. Silicon Carbide, in particular, has promising applications to the automotive, aerospace, and utilities industries among others. Commonly used to create solid electrical and mechanical connections in high power systems, busbars are critical in ensuring system reliability in terms of voltage spike and temperature rise. Laminated busbars, commonly consisting of heavy copper planes separated by a non-conductive substrate, are widely used in industry due to their mechanical, electrical, and thermal robustness. Printed circuit boards (PCB) have advantages over laminated busbars in developing high power density systems. While the optimization of laminated busbar design has been widely reported, high power PCB busbars are less represented in literature. Therefore, a simulation-based methodology used to analyze and optimize the design of PCB busbars using finite element analysis (FEA) tools will be discussed. Two systems were considered for these studies including a 135 kW SiC traction inverter and a 125 kVA SiC inverter used in an active harmonic filter. Components comprising the power loop, including the PCB busbar, power module, and heavy duty interconects were modeled in Q3D to extract the loop inductance for both systems. The two experimental methods used to validate simulation results included double pulse tests (DPT) and impedance measurements. The busbar design in the 135 kW system was optimized using Ansys Q3D, resulting in a 19 % reduction in voltage spike amplitude according to double pulse tests.

  • Producing Fuel and Electricity from Coal with Low Carbon Dioxide Emissions
    Producing Fuel and Electricity from Coal with Low Carbon Dioxide Emissions K. Blok, C.A. Hendriks, W.C. Turkenburg Depanrnent of Science,Technology and Society University of Utrecht Oudegracht320, NL-351 1 PL Utrecht, The Netherlands R.H. Williams Center for Energy and Environmental Studies Princeton University Princeton, New Jersey08544, USA June 1991 Abstract. New energy technologies are needed to limit CO2 emissions and the detrimental effects of global warming. In this article we describe a process which produces a low-carbon gaseousfuel from coal. Synthesis gas from a coal gasifier is shifted to a gas mixture consisting mainly of H2 and CO2. The CO2 is isolated by a physical absorption process, compressed,and transported by pipeline to a depleted natural gas field where it is injected. What remains is a gaseousfuel consisting mainly of hydrogen. We describe two applications of this fuel. The first involves a combined cycle power plant integrated with the coal gasifier, the shift reactor and the CO2 recovery units. CO2 recovery and storage will increase the electricity production cost by one third. The secondprovides hydrogen or a hydrogen-rich fuel gas for distributed applications, including transportation; it is shown that the fuel can be produced at a cost comparable to projected costs for gasoline. A preliminary analysis reveals that all components of the process described here are in such a phase of development that the proposed technology is ready for demonstration. ~'> --. ~'"' .,.,""~ 0\ ~ 0\0 ;.., ::::. ~ ~ -.., 01) §~ .5~ c0 ~.., ~'> '" .~ ~ ..::. ~ ~ "'~'" '" 0\00--. ~~ ""00 Q....~~ '- ~~ --. ~.., ~ ~ ""~ 0000 .00 t¥") $ ~ .9 ~~~ .- ..~ c ~ ~ ~ .~ O"Oe) """1;3 .0 .-> ...~ 0 ~ ,9 u u "0 ...~ --.

Experimental tests concerning busbars are very expensive and difficult to be executed. Therefore, the great advantage for setting the valid parameters for busbar systems components are analytical calculations supported by FEM (finite element method) modelling and analysis. Determining electrodynamic forces in busbar systems tends to be crucial with regard to subsidiary, dependent parameters. In this paper analytical calculations of asymmetric three-phase busbar system were carried out. Key parameters, like maximal electrodynamic forces value, mechanical strength value, busbar natural frequency, etc., were calculated. Calculations were conducted with an ANSYS model of a parallel asymmetric busbar system, which confirmed the obtained results. Moreover, showing that a model based on finite elements tends to be very helpful in the selection of unusually-shaped busbars in various electrotechnical applications, like switchgear.

  • Voltage Control Issues in Low Voltage Networks with Microgeneration
    VOLTAGE CONTROL ISSUES IN LOW VOLTAGE NETWORKS WITH MICROGENERATION Rui Castro, M. E. Almeida, Célia Jesus, Pedro M. S. Carvalho and Luís A. M. Ferreira Centre for Innovation in Electrical and Energy Engineering (Cie3), IST – Technical University of Lisbon, Lisbon, Portugal Keywords: Voltage Control, Microgeneration, Transformer Tap Changer, Unbalanced Load Flow. Abstract: In the framework of the so-called microgeneration, small photovoltaic units are being installed in the roofs of the buildings and connected to the low-voltage distribution networks. This is posing some new challenges to the distribution network operators. On one hand, the off-service regulation of the transformer taps must comply with a hard twofold objective: to mitigate the undervoltages during peak load periods and to mitigate voltage rise during peak generation periods. On the other hand, the voltage profile is almost insensitive to microgeneration injected reactive power, which forces control to actuate on active power with the consequent impact on energy produced and also on network security. These two aspects of the problem are addressed in this paper with help from an illustrative test network, on which several case-studies have been built to highlight the main voltage control problems and to test different strategies to overcome such problems. 1 INTRODUCTION undertaken. Traditionally, this issue is dealt with by an appropriate reactive power control. This can be Recently, governments are encouraging the locally performed by the inverters of the PV, which installation of small Photovoltaic (PV) units (usually hold power factor regulation capabilities. However, in the roofs of the buildings), typically sized in the reactive power control is very ineffective in LV range of some kW and connected to the Low networks due to the low inductive component of the Voltage (LV) distribution network, in the framework LV lines/cables.

In particular, in the form of decentralized energy sources located to their customers, small hydropower (SHP) improve grid stability by diversifying the electricity system and reducing power loss. The mountainous distribution networks supplied by small hydropower are closed-loop design but open-loop operation, which easily causes the tripping of tie line even further the off-grid operation of small hydropower system. Once the tie line trips, the current countermeasures—such as hydropower shutdown and load shedding—do not fully guarantee the reliability of power supply and the utilization efficiency of hydropower. This paper studies the amplitude-frequency characteristics of SHP off-grid, according to the typical integration of hydropower in South China, a SHP on-grid/off-grid model is established based on the Power Systems Computer Aided Design (PSCAD) platform.
