48-Volt Developments

2015-11-09

Development of higher-voltage electrical systems in vehicles has been slowly progressing over the past few decades. However, tightening vehicle efficiency and emissions regulations and increasing demand for onboard electrical power means that higher voltages, in the form of supplemental 48 V subsystems, may soon be nearing production as the most cost-effective way to meet regulations. The displacement of high-wattage loads to more efficient 48 V networks is expected to be the next step in the development of a new generation of mild hybrid vehicles. In addition to improved fuel economy and reduced emissions, 48 V systems could potentially save costs on new electrical features and help better address the emerging needs of future drivers. Challenges to 48 V system implementation remain, leading to discussions by experts from leading car makers and suppliers on the need for an international 48 V standard. Initial steps toward a proposed standard have already been taken.

Advances in Electric Propulsion

2017-05-18

Aviation propulsion development continues to rely upon fossil fuels for the vast majority of commercial and military applications. Until these fuels are depleted or abandoned, burning them will continue to jeopardize air quality and provoke increased regulation. With those challenges in mind, research and development of more efficient and electric propulsion systems will expand. Fuel-cell technology is but one example that addresses such emission and resource challenges, and others, including negligible acoustic emissions and the potential to leverage current infrastructure models. For now, these technologies are consigned to smaller aircraft applications, but are expected to mature toward use in larger aircraft. Additionally, measures such as electric/conventional hybrid configurations will ultimately increase efficiencies and knowledge of electric systems while minimizing industrial costs.

Electric Vehicle Forecasts, Trends and Opportunities 2015-2025

2014-10-01

This master report summarizing and forecasting every sector of the EV industry remains unique. It adds new sectors as they become substantial, the latest being car-like micro-EVs homologated as quadricycles in Europe. Many profitable niches are emerging just as the largest major sectors are changing in importance; the industrial and commercial sector is now bigger and much more profitable than e-cars, and is set to remain so for at least eight more years. All components are changing with supercapacitors sometimes replacing or partly replacing batteries and also new types of battery, energy harvesting, power electronics and structure powering growth. Disruptive change is now the norm and the fruits of all this are truly spectacular; including such things as the Marian fast- surface boat that acts as a submarine when necessary, the fixed-wing plane that will stay aloft for five years on sunshine and the flying jet ski.

Energy Harvesting/Regeneration for Electric Vehicles Land, Water & Air 2015-2025

2014-12-01

The electric vehicle industry - land, water and air - is rapidly rising to become a market of over $533 billion by 2025. Some run entirely on harvested energy as with solar lake boats. Others recycle energy as with regenerative braking of cars, buses and military vehicles harvesting kinetic energy. Others use different forms of harvesting either to charge the traction batteries, or to drive autonomous device. In some cases, harvesting is making completely new forms of electric vehicle possible such as "glider" Autonomous Underwater Vehicles (AUVs) that can stay at sea for years, gaining electricity from both wave power and sunshine. Multiple forms of energy harvesting on one vehicle are becoming more common from cars to superyachts.

Future Technology for Hybrid and Pure Electric Cars 2015-2025

2014-11-01

E-cars are oversupplied and changing in all respects but in this frenzy of birth and death the future is being created with hybrid cars rapidly gaining market share. The sales of pure electric cars are likely to take off in the second half of the coming decade as certain technical and cost challenges are resolved. Toyota and Tesla have hugely benefitted from correct market positioning. Yet, Toyota is now betting strongly on fuel- cell hybrids, and Tesla on mainstream pure electric cars. A vicious shakeout of car and battery manufacturers has commenced with the winners expecting a handsome pay-off. IDTechEx finds that the global sales of hybrid and pure electric cars will triple to $178.9 billion in 2024 as they are transformed. For example, components are becoming integrated; the range extender, as an optional extra, breaks down the difference between pure electric and hybrid. Car manufacturers vertically integrate and collaborate, competing with their suppliers.

History of the Electric Automobile

1993-08-01

History of the Electric Automobile covers the evolution from the first electric vehicles of the 1880s to the advances of today. Beginning with early electric vehicle development in England, France, and the United States, this book provides an in-depth look at the so-called "golden age of electric vehicles" (1895-1905), demonstrating the technological improvements and business risks of this era. This history also explores the "dead period" of the 1930s, 1940s and 1950s, and the subsequent re-birth of interest in electric vehicles in the early 1960s. Events which have impacted the development of electric cars since then -- most notably the Electric Vehicle Act of 1976 -- are also examined. The book also features an appendix section containing such information as a name table of American electric cars, the Electric Vehicle Act of 1976, "nostalgia", and more. A glossary and index are also included.
