Theodore Bohn, Principle Investigator, Plug In Hybrid Vehicle Propulsion Systems, Argonne National Lab - Center for Transportation Research: "Advances in Simplified Hybrid Electric Vehicle Powertrain Systems and Matching Energy Storage Technologies"
Drivetrain electrification takes many forms in vehicles today, from mild hybrid vehicles, to full battery electric vehicle power train configurations. One of the trends in increasing on-road vehicle fuel economy is to reduce vehicle mass. Decreasing vehicle mass can also allow a smaller/lighter powertrain, which allows a lighter vehicle structure. This principle is called mass reduction compounding. One question in hybrid vehicle powertrain design, for on-road vehicles, as well as for Industrial Utility Vehicles, is “What is the simplest hybrid vehicle powertrain system? This talk compares various hybrid topologies such as series, parallel, and powersplit with respect to part counts and component sizing.
One of the most expensive and fragile parts of an electric powertrain is the energy storage system, or battery. Limitations and advancements in battery technology will also be discussed in this talk, along with comparative life cycle costs of various battery solutions.”
