The Story of Electricity

In a recent newspaper article (Guernsey Island Power Supply in May 2012), we say that the electricity bill increases and the reliability of supply drops or becomes unstable. Obviously, this will bring considerable suffering and discomfort to the residents of Guernsey. The purpose of this article is to explain how electricity is in people's life and why it is so important. As a background, it is important to explain what electricity actually means.

Media occasionally gives the impression that "Electric Vehicle" is a car with lithium-ion battery. But this is only part of the story. Electric vehicles include battery electric vehicles (BEV) and plug-in hybrid electric vehicles (PHEV) and fuel cell electric vehicles (FCEV). PHEV uses a combination of an internal combustion engine and a battery electric drive system, but BEV and FCEV are very simple all-electric vehicles, it is possible to reduce exhaust emissions to zero.

Electric cars first appeared in the mid 19th century. Electric cars maintained their car's ground speed record around 1900. Compared to modern internal combustion locomotives, high-cost, low-speed and short-range battery electric vehicles continue to be used in the form of electric vehicles and other niche applications, but their reduction in worldwide use Brought. At the beginning of the 21st century, there is growing interest in issues related to hydrocarbon fuel vehicles, such as environmental damage due to emissions, the sustainability of existing hydrocarbons, interest in electric vehicles and other alternative fuel vehicles . Increase. Improvement based on transportation infrastructure and electric vehicle technology

Electric vehicles are various electric vehicles (EV). The term "electric vehicle" refers to any vehicle propelled using an electric motor and "electric vehicle" generally refers to a vehicle that is electrically driven and has highway functions. Neighboring electric vehicles (NEV) in the United States, electric four wheel bikes in Europe, plug-in electric mini-cars or low-speed electric vehicles classified as urban type vehicles are limited in terms of weight, output and maximum speed. Some countries allow running on public roads and streets at a certain speed limit

When people think about electric cars, we consider transportation methods driven by electricity such as trains and trams. Their technical terms are electric cars. Burton (page 10) states that electric vehicles are defined not as ordinary vehicles using diesel engines and gasoline engines, but as at least partially electrically operated cars. Electric cars are driven by electric motors that draw electricity and fuel cells from batteries. Contrary to the general idea, electric vehicles have not been invented in the 21st century.
