GM is pursuing an electrification strategy to reduce dependence on petroleum by developing a portfolio of advanced propulsion technologies including hybrids, plug-in hybrids, extended range electric vehicles, and fuel cell EVs. A key part of the strategy is the Chevrolet Volt, an extended range electric vehicle that can drive up to 80 km on battery only but has a gas engine range extender for an overall driving range of up to 490 km. Significant technological advancements are still needed to improve electric drive systems, batteries, power electronics, and controls to make electric vehicles more affordable and appealing to mass market buyers.
B E Aerospace case study - Oracle Primavera P6 Collaborate 14p6academy
The document discusses B/E Aerospace's initial implementation of Primavera EPPM and how it was turned around. The initial implementation focused only on software functionality without considering business processes. This led to inconsistent results across business units. To correct this, B/E Aerospace took an implementation approach focusing on people, processes, and change management. Key aspects included identifying sponsors, developing a roadmap aligned with objectives, and measuring and improving adoption through communication and process changes. Current state shows improved ownership, organization, data integrity and stakeholder trust in the system.
The document provides an overview of electric vehicles (EVs) and their connection to the smart grid. It discusses the history of EVs from their invention in the 1800s to their resurgence today. Popular EV models like the Chevy Volt, Nissan Leaf, and Tesla Model S are highlighted. The document also outlines how EVs can interact with the smart grid by storing energy during off-peak hours and how drivers can charge their EVs at home or in public. Tips are provided on getting the best utility rates for charging EVs. The future of EVs and their potential impact on reducing oil dependence and carbon pollution is also noted.

AirVenture 2009 Electric Propulsion PresentationBye Aerospace
This document summarizes George Bye's presentation on hybrid/electric propulsion systems for general aviation aircraft. Bye has over 20 years of experience in aviation and is the CEO of an energy technology company. He discusses the benefits of electric propulsion systems, including improved efficiency and reduced fuel costs and emissions. The technology overview outlines improvements in battery, motor, and charging technologies that are bringing electric propulsion within reach for small aircraft under 250 horsepower. Bye's company is developing a hybrid electric propulsion system for certification and aims to have an all-electric certified aircraft within 5 years. Adoption of these technologies could significantly reduce operating costs for aircraft owners and training schools.
Challenges of future aircraft propulsionDenny John
This document discusses distributed propulsion technology and its potential application for future all-electric commercial aircraft. It outlines challenges with current aircraft propulsion systems, including high fuel consumption and noise and emissions. Distributed propulsion aims to address these issues by dividing thrust across multiple smaller engines distributed around the aircraft. The document reviews literature on early aircraft with distributed propulsion designs. It also examines challenges for implementing distributed electric propulsion on commercial aircraft, such as managing increased weight and electrical systems complexity.

1) The document discusses electric vehicles and their potential impact on energy grids. It addresses concerns that charging electric vehicles could overload grids but argues this is not the case if charging is properly managed.
2) Charging electric vehicles can be managed at multiple levels from individual charging stations to the overall grid level to avoid peak demand times and make use of excess renewable energy production.
3) With management of electric vehicle charging, the grids will be able to support electric vehicles and the vehicles will provide benefits to the grid by enabling demand response and storing energy to help integrate more renewable resources.
The document discusses the outlook and policy actions needed for electric vehicles. It argues that electric vehicles are more sustainable than gasoline vehicles, using 30% less primary energy and emitting 25% less carbon dioxide. However, for electric vehicles to spread, governments need to provide initial incentives like preferential parking and lanes, as well as building out charging infrastructure, especially for home charging. With the right policies, electric vehicle sales are predicted to increase as costs fall with higher production volumes and rising gasoline prices.
The document discusses research on hydrogen enriched natural gas (HCNG) internal combustion engines. It provides background on using HCNG as a fuel, including that adding hydrogen to natural gas can increase combustion speed and efficiency while reducing emissions. It then outlines Tsinghua University's research activities on HCNG engines, including testing systems, control strategies, and matching engines with oxidation catalysts to reduce emissions.
1) Key factors that influence lithium battery cost-effectiveness include the purchase cost per kWh, ownership costs related to cycle life and warranty, and end-of-life disposal costs.
2) Maximizing the usable energy of a battery pack is important for optimizing costs, as it allows manufacturers to increase energy capacity while maintaining or lowering the purchase cost per kWh.
3) Reliability features, proven components, standardized modular designs, and local sourcing can help reduce the ownership costs associated with battery packs over their lifetime.
The document discusses the global outlook and development of electric vehicles and their infrastructure. It covers technical roadmaps and challenges of EVs, as well as power batteries and smart grid infrastructure. The professor argues that EVs represent a disruptive industry that requires coordinated development between governments, automakers, and suppliers to establish new industrial alliances and supply chains. EVs will play a key role in achieving global sustainable development goals.
