Electric car
Electric cars are vehicles powered by electric motors, offering smooth acceleration and instant torque. They gained popularity in the late 19th century but waned due to internal combustion engines; however, advancements since 2008 have reignited interest in electric vehicles, driven by improvements in batteries. While they have advantages such as zero emissions and lower running costs, challenges include high initial prices, limited range, and slow charging times.

- 1. Index: · What areelectric cars? · History · How do they work? · Advantages · Disadvantages
- 2. An electric caris an automobile that is propelled by one or more electric motors. Electric motors give electric cars instant torque, creating strong and smooth acceleration.
- 3. The first electriccars 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.
- 4. While most currenthighway-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 batteries Nickel iron batteries Etc.
- 5. Advantages: - No gasis 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.
- 6. -The first disadvantageis 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
