Green Vehicle Research, Development and Training


powertrain

Volatile oil prices and concerns with Internal Combustion Engine (ICE) emissions give rise to the recent development of hybrid electric vehicles (HEV) and fuel cell vehicles (FCV). With the abundantly available, clean hydro power in Canada, development of plug-in hybrid electric vehicles (PHEV), extend range electric vehicles (EREV) and electric vehicle (EV) provides more promising solutions to the increasing energy and environment concerns.


The University of Victoria Green Vehicle Technology (UVic-GVT) team has been working on the development of contemporary hybrid powertrain designs with multiple-mode architectures and plug-in capability in the following areas.


The UVic-GVT research and development efforts cover the following areas:


  1. Development of advanced HEV/PHEV/EREV modeling, simulation and design optimization tools to support better ecocar_modelunderstanding of the complex, azuremultiple-mode hybrid powertrain architectures and to introduce the new global optimization based hybrid powertrain design method (past and present HEV design is largely trial and error based).

    This fundamental research opens the doors for new knowledge and design innovations for HEV/PHEV/EREV/FCV, and lead to the development of next generation, innovative hybrid powertrain architectures.

  2. EcoCAR: The NeXt Challenge program - development of next generation hybrid vehicle technology and training of future hybrid technology leaders

    The focus of this design competition is to develop and integrate technologies that will reduce petroleum energy use, fuel EcoCar_Teamconsumption and emissions while at the same time provide the consumer with a fully-functional and marketplace ready vehicle. The UVic EcoCAR team is EcoCar_Teamdeveloping an innovative 4WD, two-mode plus, EREV on the 2010 Saturn VUE platform with a 2.4L flex-fuel (E85 ethanol capable) engine, GM 2-mode hybrid transmission, a UQM Powerphase 125 rear traction motor, a newly designed 21kWh A123 battery pack, as well as new vehicle electronic control unit (ECU) and power management system. The UVic team is proud to be one of 17 universities across North America selected to participate in this prestigious competition and to win the second place overall and six other major awards during the first year competition in June 2009. Drs. Z. Dong and C. Crawford are the faculty advisors of the UVic team. The UVic EcoCAR Team Awards include:ecocar

  3. Development of a generic and flexible low-speed fuel cell hybrid electric vehicle model using MathWorks SimDriveline vehicle powertrain modeling/simulation tool and semi-empirical PEM fuel cell system model

    fuelcellOver the past several years, the research team has developed and updated the semi-empirical PEM fuel cell stack and system models. The model was originally based upon the RMC Ballard PEMFC stack. The parameters of the model were changed using experiment data acquired from our stack tests on a Palcan 1.2 kW PEM fuel cell stack at UVic and improved with additional considerations. To effectively form a fuel cell hybrid electric vehicle model, we are integrating this PEMFC stack/system model into the vehicle performance model constructed using the new MathWorks SimDriveline vehicle powertrain modeling and simulation environment. This will provide us the flexibilities to explore various hybrid vehicle architectures, powertrain component sizes and control algorithms.

  4. Dynamometer tests of low-speed electric vehicle and fuel cell hybrid electric vehiclefc_scooter

    Due to the complexity of advanced hybrid powertrain and ESS, and the complexity their interlinked control systems, these new powertrain designs and the control programs need to be extensively tested during the development. Computer modeling and simulation can reduce the needed tests, but can never replace testing. At the same time, testing and experiments using full size prototype vehicles are both expensive and inefficient, due to the high cost, large size and complexity of commercial vehicles, particularly the commercial trucks and buses, and due to the instrumentation challenges for vehicles designed for commercial operations.

    dyno_dialWe have developed a customized dynamometer for tests of low-speed electric vehicles and fuel cell hybrid electric vehicles. At present, comparable studies on vehicle performance between the experiment results and simulation results, and on the performances of a battery electric vehicle and a PEMFC-battery hybrid vehicle (scooter for the simplicity of testing) with identical powertrain other than the power plants are under way with some preliminary results. More in-depth findings will be reported after the data are processed.

  5. Development of advanced HEV/PHEV/EREV powertrain Hardware-in-Loop (HIL) and testing facilities.
    unknown
    The HIL system and vehicle testing facilities are essential for the validation of newly developed hybrid powertrain modeling, simulation and design optimization tools, and for verifying new HEV/PHEV/EREV designs and various complex control algorithms at manageable cost before the expensive prototype vehicle is produced. Advanced HIL system implemented using dSPACE industrial controller for new UVic green vehicles, and chassis dynamometers for low-speed EV/FCV have been developed at UVic.

  6. Development of a general purpose, versatile hybrid powertrain and vehicle testing platform, serving as a intermediate level experimental facility between the HIL and the full size vehicles (SUV and truck)

    The availability of a general purpose, versatile hybrid powertrain and vehicle testing platform will allow the UVic GVT team to test and turn advanced hybrid powertrain design and control algorithms prior to the costly development of full-scale SUVs and commercial trucks.

    The versatile and low-cost testing platform will considerably speed up the transfer of new technology from research laboratory to company, and make investigation of new ideas quick, effective, and affordable.

    1. Test of various hybrid powertrain architectures, including series, parallel and power split, two-mode and two-mode plus, and multi-regime

    2. Test of various energy storage systems (ESS), including various types of batteries, ultracapacitors, and hybrid ESS with both batteries and ultracapacitors

    3. Development of new hybrid powertrain design for larger commercial vehicles (trucks, vans, and buses)
