What actually are electric vehicles?

Electric vehicles are vehicles that are powered by electricity. This includes cars, trucks, buses, planes, and boats. There are different types of electric vehicles, including all-electric vehicles, hybrid vehicles, plug-in hybrids, and fuel-cell vehicles.

All-electric vehicles use only a battery for power. Hybrid vehicles use a combination of a combustion engine and an electric motor. Plug-in hybrids are like hybrid vehicles, but the batteries can also be recharged directly when plugged in. Fuel-cell vehicles generate their own electricity from onboard fuels such as hydrogen.

Electric vehicles are becoming increasingly popular because they are more efficient and environmentally friendly than vehicles with combustion engines.

A brief overview of the history of electric vehicles

Electric cars were invented over 100 years ago, but they didn’t become popular until the early 1900s. The main issue with electric cars at the time was that the batteries weren’t rechargeable.

The first electric production car was developed in London in 1884 by Thomas Parker. Electric cars soon became very popular, particularly in the US. However, the large-scale production of Ford’s petrol cars and the increasingly affordable price of oil soon meant that electric vehicles couldn’t compete.

Interest in electric vehicle technology was renewed in the 1970s and 1990s. In the late 2000s, Tesla launched its first Roadster, which was a major breakthrough in electric car technology.

Nowadays, most major manufacturers have at least some electric or hybrid vehicles in their range. Electric cars are becoming more and more popular, and battery manufacturing is better than ever.

How long does it take to charge an electric car?

There are a few variables to take into account when it comes to electric car charging. The first is the type of battery used – most use a Lithium-ion (Li-ion) battery, although the capacity will often differ. Next is the type of charging used – a standard home 7kW charging point will be a lot slower than a rapid 150kW one.

As an example, the 2019 Tesla Model S has a 75kWh battery. To fully recharge it, estimates suggest 11 hours for a 7kW charger, but less than an hour for a 150kW charger. 

Are electric cars the future of transportation?

In a word, yes. Electric vehicles are high on the agenda for several global superpowers, including the UK, the USA, and China. As you’ve likely read, green transportation policy factors heavily on political agendas, with science guiding the way. 

Additionally, according to Wood Mckenzie experts, sales of electric vehicles are predicted to exceed 45 million annually by 2040, adding 323 million EVs to the world’s stock.

There is no doubt that electric cars lower emissions and help combat climate change. And by 2035, we’ll see them usurp petrol and diesel models as the default new car option. 

Building a sustainable future, though, requires work in a variety of fields. And sustainable energy sources must power electric vehicles to be fully effective.

From my point of view, electric cars are environmentally friendly, cost-effective, and showcase technological advancements, providing impressive performance. Moreover, the ongoing expansion of charging infrastructure enhances their convenience. In summary, they offer a promising alternative with environmental benefits, cost efficiency, and technological progress.
