Future Vehicles May Arrive Soon [Automotive Electronics

After the two last virtual conferences in 2019 and 2020 run by Prof. Pablo Arboleya from the University of Oviedo (Spain), the IEEE Vehicle Power and Propulsion Conference (VPPC) was held for the first time in Merced, California, USA, last November. The conference was organized by a very motivated team from the University of California, Merced, led by Prof. Ricardo De Castro. With the motto “connect green e-motion” worldwide in a complete network, the four-day conference delivered insight and intelligence from several key players at the forefront of hybrid and electric vehicle (EV) development. A very attractive program was prepared, including four outstanding keynote speeches, three tutorial lectures, and the in person or virtual presentation of 143 papers. During the last conference day, attendees had the opportunity to visit two technical sites: TRC California and the University of California, Berkeley. VPPC 2022 was the first VPPC after the COVID-19 lockdowns and was run in hybrid mode, with in-person and online attendees. VPPC 2022 continues to be the venue for researchers, educators, and engineers to share the latest results in research, teaching, and development of EV and hybrid vehicles and related technologies, as shown in <xref ref-type="fig" rid="fig1" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Figure 1</xref> . It was an important forum where the academic and industrial communities and policymakers discussed new technology trends and collaboration for mutual development at a crucial time just before the 2022 United Nations Climate Change Conference.

The Vehicle Industry Is Moving Fast [Automotive Electronics

After the successful 2019 edition in Hanoi, Vietnam <xref ref-type="bibr" rid="ref1">[1]</xref>, the IEEE Vehicle Power and Propulsion Conference (VPPC) rotated to Europe and was held for the first time in Gijon, Spain, for the two last editions due to the COVID-19 pandemic <xref ref-type="bibr" rid="ref2">[2]</xref>, <xref ref-type="bibr" rid="ref3">[3]</xref>. The ticklish situation in the spring and summer of 2020 around the world forced it to move to a virtual conference. As the organization committee, led by Prof. Pablo Arboleya, set out an excellent program to receive the international attendees, the VPPC steering committee decided to give the opportunity to the Gijon organization to have an on-site conference giving them the organization of the next VPPC edition in 2021. This is an opportunity to keep appointments with the event center, catering, hotels, and so on. Unfortunately, the pandemic situation remains difficult during 2021 and the VPPC 2021 edition was also prepared as a remote event between 25 October and 14 November. A very motivated team from the University of Oviedo&#x2014;Gijon campus organized the last two editions with the motto &#x201C;Connect green e-motion worldwide in a complete network,&#x201D; and the Technical Program Committee (Prof. G. Gruosso, Italy; Prof. R. de Castro, the United States; and Prof. J. Garcia, Spain) prepared a very attractive program, including outstanding keynote speakers, tutorial lectures, and the remote presentation of 303 papers (VPPC 2020&#x2014;163 and VPPC 2021&#x2014;140) from 29 countries (see <xref ref-type="fig" rid="fig1">Figure 1</xref>). VPPC 2020 and VPPC 2021 were the first VPPC virtual conferences in its history of 18 editions. VPPC continues to be the venue for researchers, educators, and engineers to share the latest results in research, teaching, and development of electric and hybrid vehicles and related technologies. It is an important forum where the academic and industrial community and policy makers discuss new technology trends and collaboration for mutual development in the important moment where new resolutions were taken by international leaders after 2021 United Nations Climate Change Conference.

Modelling and design of a pneumatic CRONE suspension architecture for ride comfort

This paper focuses on the development of the pneumatic CRONE suspension consisting of two different suspension architectures and a switching between them. The so called stiff architecture is oriented to the road behaviour. It enables the use of the levelling system, allowing, amongst others, the body control under driver inputs [Bouvin J-L, Moreau X, Benine-Neto A, et al. CRONE body control under driver inputs through heave velocity regulation, 2017 IEEE Vehicle Power and Propulsion Conference (VPPC), Belfort, France; 2017]. The second one, called CRONE architecture, isolates the vibrations from irregularities in the road surface. It provides outstanding performances in terms of body control under road inputs, robustness of body control to sprung mass variations and vibration isolation. It also enables to resolve the dilemma between mass and damping coefficient, inherent to classic suspensions.

Energy Management in Fuel-Cell\/Battery Vehicles: Key Issues Identified in the IEEE Vehicular Technology Society Motor Vehicle Challenge 2017

In October 2016, an international challenge devoted to the energy management of a fuel-cell (FC)/battery vehicle was launched during the 2016 IEEE Vehicle Power and Propulsion Conference (VPPC), in Hangzhou, China. The vehicle driving cost, which includes the hydrogen (H2) and source degradation costs, was used as a base of comparison.

Guest Editorial Special Section on Electric Powertrains for Future Vehicles

The papers in this special section focus on electric power trains, with particular emphasis on state-of-the-art research and development and new design concepts. These papers were presented at the IEEE Vehicle Power and Propulsion Conference (VPPC) that was held in Hangzhou, China, in October 2016.

Special Section on Advanced Powertrains for More Electric Vehicles

The papers in this special section were presented at the IEEE Vehicle Power and Propulsion Conference (VPPC) that was held in Coimbra, Portugal, in October 2014. Advanced traction and propulsion systems are developing in order to ensure better energy performance, reduced operating cost, and higher lifetime of future transportation systems like road vehicles, as well as more electric trains, subways, ships, and airplanes. Such a powertrain integrates several complex subsystems (including power or energy sources, electricmachines, power electronics,mechanical transmission), and it becomesmandatory to consider the whole system in order to reach the best performance.

Estimating Thermal Parameters of Large-Format Laminated Lithium-Ion Batteries Using Thermal Impedance Spectroscopy

The accuracy of battery thermal parameters is crucial to the accuracy of thermal simulations for batteries. Given the structural characteristics of the large-format laminated lithium-ion battery [1], effective methods to determine multiple thermal parameters, such as the thermal conductivity and the specific heat capacity, should be developed to achieve better prediction of battery thermal behaviors.Generally, the methods for measuring the thermal parameters of batteries can be divided into two categories, the time-domain method and the frequency-domain method. The authors developed a joint computational and experimental time-domain method to estimate the multiple thermal parameters for a 25 Ah laminated lithium-ion battery both in-situ and simultaneously [1]. However, the battery temperature changed from 25 to 35°C in the experiment, hence the estimated thermal parameters were the average properties over 25~35°C. In contrast, the change in the temperature of the sample can be greatly reduced in the frequency-domain method, making it possible to obtain the thermal parameters at different temperatures.In this work, a frequency-domain method, the thermal impedance spectroscopy (TIS) method is used to simultaneously and in-situ determine two thermal parameters, i.e. thermal conductivity and specific heat capacity, for the large-format laminated lithium-ion battery.In the experiment, a planar electric heater is sandwiched between two identical batteries (25 Ah, 250 mm × 220 mm × 7.2 mm，NMC-LMO/Graphite), as shown in Fig. 1(a). The electric power for the heater is adujusted at different frequencies (0.1, 0.2, 0.4, 0.6, 0.8 and 1 mHz) and the temperature response on one outer surface is recorded with the attached thermocouple. The entire set-up is placed in an environment chamber.The heat transfer behavior between the heating power and the temperature response is examined in the frequency domain. An equivalent thermal circuit including thermal capacity and resistance is introduced to derive the analytical expression of thermal impedance, as shown in Fig. 1(b). The thermal circuit is simplified from the 1D heat conduction model, which also takes the covering aluminum-plastic film into account. The thermal conductivity and capacity of the battery core are estimated using the least-square fitting algorithm. The experimental and fitted thermal impedance are shown in Fig. 1(c).The estimated parameters are validated against the results from the accelerating rate calorimeter (ARC), the heat flow calorimeter (HFC) and the joint computational and experimental time-domain method [1].
