WHAT ARE ELECTRIC CARS?

An electric car is an automobile that is propelled by one or more electric motors.

Electric motors give electric cars instant torque, creating strong and smooth

acceleration.

HISTORY

The first electric cars were produced in the 1880´s and became popular in the late 19th century and early 20th

century until advances in internal combustion engines and mass production of cheaper gasoline vehicles

led to a decline in the use of electric drive vehicles. The energy crisis of the 70´s and 80´s brought a short-

lived interest in electric cars, but since 2008, a renaissance in electric vehicle manufacturing has occurred due to

advances in batteries and power management.

HOW DO ELECTRIC CARS WORK?

While most current highway-speed electric vehicle designs focus on lithium-ion and other lithium-based

variants a variety of alternative batteries can also be used in electric cars, such as:

Lead acid batteries  Zinc-air batteries

Molten salt batteriesNickel iron batteries

Etc.

ADVANTAGES & DISADVANTAGES

Advantages:

- No gas is required, some electric cars have a battery range of 40 miles without any gas consumption.

- Electricity is much cheaper than gas, and you can plug the car into any outlet of the proper voltage.

- Electric cars give off no emissions, they are better than hybrids in this because the are 100% free of pollutants.

- Safety is a big concern with these vehicles. However, the fluid batteries actually take impact better than a fully made gas car, and can help even more in the event of an accident.

DISADVANTAGES:-The first disadvantage is the price. Electric car

batteries are not cheap, a 40 miles range vehicle sells for around 30.000$.

-These cars make no silence, so people won´t hear if one of this cars is coming and an

accident could occur.

-Most of the batteries of electric cars are slowly charged, it take you hours to fully charge them.

-Mostly all the electric cars have a range of less than 25 miles and the top speed of most models is 60 miles per hour, but this will improve in the

future
