  • Distance Traveled Dependence of Environmental Performance of Plug-In Hybrid Vehicles: Validations with Series-hybrid Vehicle Simulation

    Wei Hsiang Yang, Cheng Ping Yang, Shohei Shinta, Yushi Kamiya

    2019 IEEE 4th International Future Energy Electronics Conference, IFEEC 2019    2019.11

     View Summary

    In this paper, a series-type plug-in hybrid vehicle simulator is used to validate the distance traveled dependence of environmental performance of the plug-in hybrid vehicles proposed in our previous paper is established. First, the characteristics of the distance traveled dependence such as cross-point and the difference of CO2 emissions between AE and BLD controls are confirmed. Also, the appropriateness and usefulness of the propositions, including the CD mode control selection policy, the optimal BLD control, and the indicator BCPI (blended control performance indicator), which can simply evaluate the effect of BLD control, are valid.

  • Dependence of environmental performance of plug-in hybrid vehicles on distance traveled

    Wei Hsiang Yang, Tomohiro Suzuki, Yushi Kamiya, Yasuhiro Daisho

    2017 IEEE Vehicle Power and Propulsion Conference, VPPC 2017 - Proceedings   2018-January   1 - 6  2018.04  [Refereed]

     View Summary

    Plug-in hybrid vehicles (PHVs) have two driving modes, which are known as charge-depleting (CD) mode and charge-sustaining (CS) mode. The environmental performance of a PHV differs greatly based on the travel distance when the PHV switches from the CD mode to the CS mode. This paper focuses on the low-carbon effect and energy cost reduction effect of PHVs and numerically describes the dependence of the effects on the distance traveled. It also accounts new knowledge obtained through a detailed analysis and examination of the mathematical equations.

    31st International Electric Vehicle Symposium and Exhibition, EVS 2018 and International Electric Vehicle Technology Conference 2018, EVTeC 2018   10 ( 2 )  2018

     View Summary

    Wireless charging technology for heavy-duty vehicles has been investigated for eco-friendly transportation. We present a new wireless power transfer system for 44 kW rapid charging of electric buses. The transmission distance between the charging pads is from 10 to 13 cm. The large air gap can be fulfilled by the ordinary kneeling function, equipped on most low-floor buses. Dual-block parallel transmission with opposite-phase-current-feeding suppresses magnetic radiation. The system operates in the common 85 kHz band with the light-duty vehicle system. The result of the field test and the public road operation of two electric buses confirm the CO2 reduction effect described.

  • Performance degradation prediction and cell balance control algorithm construction of lithium iron phosphate battery

    Yasuhiro Ueeda, Koichiro Taniguchi, Shoichi Inami, Genki Kaneko, Toshio Hirota, Wei Hsiang Yang, Yushi Kamiya, Yasuhiro Daisho

    2014 IEEE Vehicle Power and Propulsion Conference, VPPC 2014    2015.01  [Refereed]

     View Summary

    Various studies were conducted from the aspects of both the battery cells and the module with the aim of making more effective use of the battery capacity. As a result, after 77 cycles of driving and rapid charging, the capacity degradation of the battery module as a whole was 7.7 % and it was determined that the cause of this additional 0.7 % degradation of the capacity was the loss of cell balance. In addition, by adopting module balance coefficient (a) that was proposed as an indicator to show the available percentage of the lowest capacity cell in the module, new cell balancing rules were created that do not significantly affect the convenience of vehicle operation.

  • Detailed modeling of motor system of plug-in hybrid vehicle: Study of detailed modeling of inverter and boost converter losses

    Wei Hsiang Yang, Hiroki Sato, Yushi Kamiya, Yasuhiro Daisho

    2014 IEEE Vehicle Power and Propulsion Conference, VPPC 2014    2014  [Refereed]

     View Summary

    This paper addresses the method of detailing the motor system including the inverter and the boost converter of plug-in hybrid vehicles (PHVs). In the past, we had to use the actual measurement data such as efficiency map to calculate the loss of a motor system. However, by estimating the output current of the motor system, allows us to separate the one loss into losses caused by the inverter, the boost converter and the motor. Based on the separation of the losses, we can then build a multi-voltage motor system or estimate the losses of the different ranks of vehicles.

     View Summary

    Electric buses have superior environmental performance because they emit no CO2and other exhaust gases while driving. However, in terms of more popularization of electric buses, it is essential to improve battery performance and realize user-friendliness of charging. To resolve these issues, a concept "short range running and frequent charging" was formulated. Under this approach, the authors have studied methods of greatly reducing the amount of large, heavy, and expensive battery. Research on non-contact inductive power supply (IPS) system has also been conducted as a way of improving charging convenience. A long-term operation test of electric buses was performed in Nagano prefecture as part of a project organized by the Japan Ministry of the Environment from 2011 to 2014. For this project the short-range frequent-charging type electric buses, "Waseda Electric Buses (WEBs)" were developed and tested on public roads to make clear the environmental performance and energy costs.

And it was estimated on Matlab simulation model that total energy consumption could be reduced by 11 % with vehicle weight reduction, modifications of drivetrain and other components.

  • Optimization of engine control methods for range extender-type plug-in hybrid vehicles

    2013 World Electric Vehicle Symposium and Exhibition, EVS 2014    2014.10

     View Summary

    This paper discusses the effects of different engine control methods on vehicle performance using a compact range extender-type PHV with a series-hybrid system. Vehicle performance was analyzed and compared in detail using two typical engine control methods: the variable control method, which drives the engine in accordance with the vehicle load, and the constant control method, which drives the engine at a constant maximum load efficiency. Specifically, by evaluating the performance in both driving tests by a test vehicle and driving simulations, we identified the characteristics of each engine control method and confirmed which is superior in terms of the seven PHV performance indices determined by the Japanese Ministry of Land Infrastructure and Transport. The comparison results quantitatively verified that the constant control reduced engine loss but caused battery loss to increase. However, since the best control method is determined by the engine and battery loss characteristics of the target vehicle, the constant control method enables superior mileage for the vehicle examined in this research due to its large engine loss reduction effect. In our case, 7.9% improvements of the charge sustaining mode mileage FCS and 7.6% improvements of the combined mileage FPH have been achieved by adopting the constant control method.
