Are you looking for Electrical Vehicles for your vehicle?

On this page, we would like to provide you with some general information about Electric Vehicles.

We hope you find this page helpful and that it may even help you decide whether to buy an Electric vehicle in the future.

If you have any questions, please do not hesitate to contact us.

Your SAI MOT Centre specialists are always happy to help.

An electric car, also known as an EV or e-car, is a vehicle that is powered by an electric motor and draws its energy from a battery instead of being powered by an internal combustion engine that requires petrol or diesel.

How does an electric car work?

An EV works by converting electrical energy into kinetic energy. A battery in the electric car stores the electrical energy and passes it on to an electric motor. The electric motor then converts the electrical energy into kinetic energy that drives the vehicle. In contrast, combustion engines burn fossil fuels such as petrol or diesel to create a small "explosion" that moves pistons and enables the vehicle to move.

Advantages of the electric car

  • Emission-free: Electric cars emit no exhaust fumes, which helps to reduce air pollution and protect the environment.
  • Lower operating costs: EVs generally have lower operating costs than conventional cars as they do not require expensive fuels. Although the current volatile electricity market is leading to higher charging prices (especially when using public charging stations), the lifetime costs are still lower due to savings on taxes and maintenance.
  • Low noise: Electric cars are very quiet, which makes driving more pleasant and reduces noise pollution in cities.
  • Suitable for everyday use: Modern electric cars have an increasingly long range.
  • Less maintenance: Electric cars have fewer moving parts than conventional cars and, therefore, require less maintenance, which saves time and money.

Challenges for EVs

  • Charging infrastructure: A sufficient charging infrastructure is required to charge electric cars and increase their range. This requires the expansion of charging stations and fast charging points. With charging apps, electric car drivers already have access to a large number of public charging points across Europe.
  • Costs: Although EVs' operating costs are lower, their purchase costs are often higher than those of comparable conventional cars.
  • Range: Although the range of electric cars has improved, they still have a limited range compared to conventional cars. This is also always part of discussions, as many people don't want to constantly stop to charge the EV (which also takes longer than refuelling). In practice, however, the ranges of electric cars are more than sufficient for everyday use and, from our personal experience, even holiday trips are stress-free. Nevertheless, battery electric vehicles are still not necessarily the best solution for every application.
  • Battery service life: Batteries in electric cars have a long service life but will need to be replaced at some point. Replacing EV batteries can be expensive and cannot be replaced by the car owner or most "normal" garages. Specialist knowledge and tools are required.*
  • Battery production: There are still some steps to be taken in the production of rechargeable batteries to make them more environmentally friendly.

Development of electric cars

The development of electric cars began in the late 19th century when the first electric car was built in the USA. In the 1950s, electric cars were even used in certain cities. In the following decades, however, electric cars were forgotten as the car industry focused on combustion engines. In recent years, however, interest in EVs has increased again as environmental concerns and stricter emissions regulations have emphasised the need for greener vehicles.

Today, there are many EVs on the market, some of which are among the best-selling cars in the world. Many major car manufacturers are committed to electromobility and are developing more and more electric vehicles. The charging infrastructure is also constantly being expanded to increase the range and potential of electric cars.

These are some of the best-selling e-cars:

  • Tesla Model 3
  • VW e-UP!
  • VW ID.3
  • Renault Zoe
  • Hyundai Kondo
  • Tesla Model Y
  • Fiat 500e
  • VW ID.4/ID.5
  • Audi Q8
  • Audi Q5 e-tron

How can electric cars contribute to the energy transition?

Reduction of greenhouse gas emissions: Electric cars do not produce direct emissions during operation, as they are powered by an electric motor that does not produce exhaust gases. Therefore, the use of electric cars can reduce CO2 emissions in the transport sector, which contributes to achieving climate targets.

Use of renewable energies: Electric cars can serve as energy storage for renewable energies such as wind and solar energy, thanks to the possibility of bidirectional charging.

Grid-friendly charging strategies: Electric cars can help stabilise the power grid by intelligently controlling the charging process. If many electric cars are charged simultaneously, this can lead to an overload of the power grid. By using grid-friendly charging strategies that postpone the charging process to times with low grid loads, BEVs can help to increase grid stability.

Reduction of dependence on fossil fuels: Electric cars reduce dependence on fossil fuels such as oil and gas, which often have to be imported. By using EVs, countries can reduce their dependence on fossil fuels and diversify their energy supply.

Overall, EVs can make an important contribution to the energy transition by promoting the reduction of greenhouse gas emissions, supporting renewable energy, contributing to grid stability and reducing dependence on fossil fuels.

However, it is crucial that the development of electric cars is supported by the promotion of renewable energies and the creation of an appropriate charging infrastructure.


Electric cars offer an environmentally friendly and cost-effective alternative to conventional cars. Although there are still challenges, such as the limited range and the need for sufficient charging infrastructure, electric mobility will continue to advance and become increasingly important. With the support of governments and industry, the future of electric mobility will be bright and pave the way for a more sustainable future.
