Today’s energy market is increasingly integrating time-varying tariffs, peak demand charges, and/or export tariffs. In this context, intelligent charging scheduling can considerably reduce the plug-in electric vehicle (PEV) charging cost. This is especially the case as more and more PEVs are charged in buildings that are also equipped with grid-connected intermittent energy resources (IERs) (e.g., photovoltaic systems and wind turbine generators). In this work, we propose a novel and complete intelligent PEV charging scheduling system (tailored for domestic settings) that can account for...

Management of electric vehicle (EV) charging is likely to be critical in avoiding large increases in peak electricity demand and subsequent build outs of generation and distribution infrastructure. Additionally, management of EV charging can help to more effectively utilize renewable energy resources. This study analyzed charging data from a real-world pilot program, the largest household-based study to date to analyze the effectiveness of different smart charging use cases at reducing charging costs and increasing utilization of renewable energy. The study included six different use cases...

Electric vehicles (EVs) are experiencing a rise in popularity over the past few years as the technology has matured and costs have declined, and support for clean transportation has promoted awareness, increased charging opportunities, and facilitated EV adoption. Suitably, a vast body of literature has been produced exploring various facets of EVs and their role in transportation and energy systems. This paper provides a timely and comprehensive review of scientific studies looking at various aspects of EVs, including: (a) an overview of the status of the light-duty-EV market and current...

The purpose of this report is to provide a research-driven analysis of options that can put California on a pathway to achieve carbon-neutral transportation by 2045. The report comprises thirteen sections. Section 1 provides an overview of the major components of transportation systems and how those components interact. Section 2 discusses the impacts the COVID-19 pandemic has had on transportation. Section 3 discusses California’s current transportation-policy landscape. These three sections were previously published as a synthesis report. Section 4 analyzes the different carbon scenarios...

Managed charging of electric vehicles has the potential to help balance energy demand on the grid and manage intermittent renewables, save costs, and reduce greenhouse gas emissions to support California’s strategy to move to full decarbonization by 2045. Electric vehicles can help achieve this goal by acting as a flexible resource for utility grids. They can curtail load when energy demand is high and accept load when energy demand is low and when there is excess generation. Shifting load to lower-cost times can also confer financial benefits to the vehicle owners.

The purpose of this study overall is to explore the policy pathways to achieve a zero carbon transportation system in California by 2045. The purpose of this synthesis report is to describe the existing state of knowledge and policy related to energy use and greenhouse gas (GHG) emissions in the transportation sector, especially in California. It is an interim product of the larger study, which will use this report as the baseline and policy context sections. The report comprises four sections. Section 1 provides an overview of the major components of transportation systems and how those...

As the number of electric vehicles is increasing, there is a pervasive call for research and new strategies in the field of vehicle grid integration. Using electric vehicle real-time data, drivers' spatial behavior and patterns can be derived for their morning and evening commute. These patterns combined with dynamic electricity costs, wholesale and retail, and variable greenhouse gas (GHG) emissions, lead to significant outcomes on savings and environmental impact. In this study, electric vehicle charging management is analyzed for the case of north California, using real world data. The...

Ride-hailing is a clear initial market for autonomous electric vehicles (AEVs) because it features high vehicle utilization levels and strong incentive to cut down labor costs. An extensive and reliable network of recharging infrastructure is the prerequisite to launch a lucrative AEV ride-hailing fleet. Hence, it is necessary to estimate the charging infrastructure demands for an AEV fleet in advance. This study proposes a charging system planning framework for a shared-use AEV fleet providing ride-hailing services in urban area. We first adopt an agent-based simulation model, called BEAM...

These sailing vessel testing, data collection and analysis project examined the real world potential for a novel carbon-fibre 'wingsail' technology to reduce fuel use in potential passenger ferryboat applications. The project involved building a carbon fibre, computer-controlled wingsail that was then mounted on a 14-metre trimaran test vessel with a complete instrumentation package. The vessel was then operated on the San Francisco Bay over a three-month period. The test results were conclusive that, for a test vessel travelling at seven knots though water on a particular ferry route, up...
