Many experts believe electric cars are the way of the future, benefiting the environment by being pollution-free. They also make less noise and have lower maintenance costs on account of featuring fewer moving parts. In contrast to conventional cars, they have no gears. All the major car-makers are now investing in electric vehicles.
An electric car comprises three main elements: an electric battery, an electric motor and an inverter. The battery produces direct current (DC) electricity. Most electric cars, however, use an alternating current (AC) electric motor because it performs more smoothly. Hence an inverter converts the DC to AC.
Electric vehicle (EV) batteries are usually made of lithium-ion cells due to their high energy density. It is possible to recharge them multiple times. The number is over 1,300 in the case of the 2020 Tesla Model 3, so it can travel 300,000 miles without significant battery degradation. These batteries are usually heavy and situated beneath the car’s floor. While they add a great deal to the weight of the vehicle, they give it a very low centre of gravity, making for a more comfortable ride.
Currently, petrol-powered cars can go for many more miles than electric ones before they have to refuel. This is because battery technology is not yet at the point where batteries can store as much energy as the same volume of petrol. Technology, however, is constantly developing, and, sooner or later, this will change. At the moment, an EV can travel for about 120 miles between charges, which is several times as much as the average Briton drives per day.
Electric cars accelerate faster. You will have to brake less because the car slows almost immediately when you take your foot off the accelerator, like a bumper car. Electricity is considerably cheaper than petrol and experts will tell you that with lower fuel and maintenance costs, an electric car is anything from 40 to 70% cheaper to run than one powered by petrol. The UK government will offer grants of thousands of pounds for the purchase of low-emission or electric cars.
People usually charge electric cars at home. Otherwise, most cars feature satellite navigation that will show the nearest public charging station, of which there are over 11,000.
