Recent advancements in battery and electric drive technologies, lower vehicle cost, and government incentives, light duty electric vehicles are gaining acceptance and market share. Some of these factors have the potential to increase acceptance of heavy-duty electric vehicles (HDEV) as well. In this webinar battery experts from the Department of Energy’s National Renewable Energy Laboratory will provide information on battery technologies with potential use in HDEVs, particularly city transit buses. We will discuss tradeoffs between different characteristics of batteries including power, energy, life, cost, charge acceptance, etc. We will also provide an overview of general battery requirements for HDEVs and discuss vehicle integration and operational considerations. Additionally we will touch on the current state of battery testing and modeling as well as some ongoing DOE and NREL battery research programs and capabilities. We expect this webinar to provide valuable information for those wishing to be more informed about batteries in the growing heavy duty EV market.
