The image shows a model of a high-performance electric car, which uses Li-Ion cell batteries, those being located on the floor, under the passenger compartment.

The car is known as the Tesla Model S, seen from side, facing left.

The Tesla Model S Performance has a range of up to five hundred and ninety kilometres, meaning it can cover this distance without having to recharge the batteries. and can reach almost a hundred kilometres per hour in no more than three seconds. It recharges electrically from special stations.

It is a rectangular, elongated car with a curved roof, a low height from the ground, being designed as a sport car.

The exterior skeleton of the car, also called the car body, is shown embossed.

The headlights and turn signals on the front, left, and rear, bottom right, are rendered by narrow, blank shapes.

The wheels at the bottom have their tires marked by embossed circles, in the center of which is another blank circle.

The car has four doors, from side being shown two, respectively the one from the driver, left, and the rear one, from the passenger compartment, right, outlined by a blank, thickened line.

The side windows at the top of the car, which are attached to the vehicle doors, as well as the windscreen or front window, left edge, are highlighted by blank shapes.

General information

After the appearance and multiplication of cars with thermal engines, it was discovered that they pollute the environment. Pollution has serious consequences for people’s health, but also on the climate. As a result of massive pollution of carbon dioxide and other gases in the environment, diseases related to the respiratory system have multiplied. At the same time, as a result of massive emissions of noxis, the greenhouse effect has arisen, which has led to the phenomenon of global warming. The increase in temperature has led to climate destabilization, and thus have multiplied extreme weather phenomena, such as hurricanes, violent tropical storms, excessive rains, but also to long periods of drought. These meteorological phenomena have led to the development of a whole chain of other associated phenomena. As a result of heavy rains, floods and landslides occur. Due to extremely high temperatures and very dry periods, forest fires occur. Thus, the whole environment is affected by man-made pollution. 

To reduce harmful emissions, people have sought various solutions to replace internal combustion engines. That is how the various electric vehicles came about. Some use the electricity supplied through the electricity grid, others use batteries, and another how many goes use hydrogen, to generate electricity. The ones that use the electricity generated by power plants are trolleybuses, trams, and electric locomotives. 

The most famous and valuable electric car company is Tesla Motors, led by Elon Musk, a man of brilliant intelligence. The vehicles manufactured by this company are based on lithium-ion batteries. These are modern batteries and are used in most electronic devices, such as phones, tablets, and laptops.

The Tesla Model S is a luxury electric car and was launched on the market in 2012. One of the important specifications of an electric car is the battery life, i.e. the distance it can travel with a single battery charge. The autonomy of this model is over five hundred kilometres, variable depending on the road conditions, driving mode and battery capacity chosen when purchasing. It reaches a speed of one hundred kilometres per hour in about five seconds, but there is also a sport variant, called Performance, which reaches the same speed in two point five seconds.

Did you know that an electric car has maintenance costs close to zero? This is because an electric car is much simpler, as it has fewer parts that can break down, compared to a thermal motor car. More importantly, it has no gearbox, and no clutch disk. 

Another interesting thing is that most electric cars have regenerative brakes. In short, we do not use the classic brake, but brake with the engine. When we use regenerative braking, the car’s engine is no longer a consumer, but becomes an electricity generator and charges the battery. If we drive down a slope, we charge back into the battery a significant amount of electricity, and thus increase the battery life of the electric vehicle. For this reason, classic brakes are rarely used, only when the car needs to be stopped urgently. As a result, the mechanical brake is not worn out.
