Electric Cars Essay
Introduction to Electric Cars
An electric car is a vehicle which is driven by electric engines. The engines use electrical energy which is usually stored in batteries. Electric car is a variation of electric vehicle (EV). EV speaks of any vehicles which are propelled by electric engines. “Electric car” is a general term for high-speed vehicles which are powered by electricity. In the United States, low-speed vehicles which are powered by electricity are known as neighbourhood electric vehicles (NEVs), and as electric motorised quadricycles in Europe.
Electric cars which are powered by different energy sources are also referred to by different names: if they are powered by sunlight …show more content…
Electric cars are more efficient compared to gas-powered cars, in terms of energy and maintenance. Electric engines use 75 per cent of the energy from the batteries to run the wheels, while internal combustion engines only use about 20 per cent of the energy from fuel. Electrical engines also require less maintenance compared to internal combustion engines. You no longer need oil to lubricate the engine. The brakes would not wear off as quickly as gas-powered cars. You do not need belts in the engines, which will wear out due to overuse, in electric cars.
Disadvantages of Electric Cars
The major disadvantage of an electric car is the batteries. Electric car batteries are not cheap. They can cost around $5,000, and the better the batteries, the more expensive they are. Not only are they expensive, but you will also need to change them more than once, as the batteries have a limited lifetime. The time required for recharging the batteries is also very lengthy. To fully charge the batteries, you need 4 to 8 hours. This is a very serious disadvantage, as most people need to have their cars ready 24/7. With gas-powered cars, you just need a few minutes to fully refill the tank.
