All over the world, electric vehicles are confidently advancing on the positions of traditional cars with internal combustion engines. According to the forecasts of experts from Bloomberg New Energy Finance, by 2040 the share of electric cars will amount to 35% of global car sales. To understand the secret of the success of electric cars, you need to understand the features of their design and construction.<\/p>\n\n

Industrial design studio KLONA will help you understand the structure and principle of operation of an electric car, as well as develop an industrial design of the car.<\/p>\n\n

Electric vehicle device<\/h2>\n\n

Outwardly, many electric vehicles may practically not differ from versions with internal combustion engines. For example, the most popular electric car in Russia, the Mitsubishi i-MiEV, is built on the same base as the Mitsubishi i gasoline hatchback. The only thing that usually gives it out on the road is the absence of exhaust pipes and specific charging hatches.<\/p>\n\n

There are often no radical differences in the interior design of the salon either. A slightly different dashboard, a joystick for driving modes instead of a gear lever – that’s all the significant innovations.<\/p>\n\n

The main discrepancies between the design of gasoline and electric versions of the car are hidden under the hood. Instead of large internal combustion engines, electric cars use electric motors the size of a watermelon. Some models are equipped with not one, but several electric motors – one for each wheel or axle. The rejection of the internal combustion engine entailed other design changes. Electric vehicles do not need lubrication, fuel supply, exhaust gas and cooling systems. Accordingly, the cars got rid of bulky radiators, exhaust pipes and oil sump.<\/p>\n\n

In addition, electric vehicles have solved the long-standing problem of the “ballast” battery. The fact is that the battery in gasoline cars is actually used only to start the engine. The rest of the time, all systems are powered by a generator. Electric vehicles do not have a special battery, which is needed only for starting. Since the traction and rotation of the electric motors are controlled by a special electronic system, it was also possible to abandon the classic gearbox with a clutch.<\/p>\n\n

It would seem that getting rid of a lot of heavy and oversized mechanisms should have provided the electric vehicle with an “air” structure. In reality, electric “iron horses” are 300-500 kg heavier than gasoline “brothers”. The fault is in the rechargeable batteries. To ensure a mileage of 200-300 km without recharging, the car has to be equipped with a battery pack weighing up to 400 kg. The weighting of the structure required strengthening the suspension and the use of more load-carrying tires.<\/p>\n\n

Tesla design<\/h2>\n\n

Before that, we disassembled electric vehicles, which were created on the basis of existing gasoline cars. The situation with the design of electric cars, developed from scratch, differs in its specificity. Consider the design features of such cars using the Tesla S model as an example.<\/p>\n\n

Before the developers of this electric vehicle there were no restrictions and the need to “fit” the electric filling into the existing “gasoline” shell. This led to many interesting design and engineering solutions.<\/p>\n\n

Two trunks<\/h3>\n\n

In front, under the hood, there is a small compartment of 150 liters, where you can fit a travel bag or suitcase. The rear rack capacity of 900 liters is enough for a couple of folding bicycles. If desired, 2 child seats can be installed there, which turns the Model S into a seven-seater family car.<\/p>\n\n

Perfect streamlining<\/h3>\n\n

Tesla’s drag coefficient is only 0.24. To achieve record aerodynamic performance, the creators came up with door handles that hide in the body when driving and a special screen for the panoramic sunroof. The abandonment of the classic radiator grille also had a positive effect on the model’s streamlining.<\/p>\n\n

Recuperation system<\/h3>\n\n

If you release the gas pedal while driving Tesla S, the wheels rotating by inertia will begin to recharge the battery. The batteries are also fed during braking.<\/p>\n\n

Autopilot mode<\/h3>\n\n

The Tesla S computer receives data from a variety of video cameras and sensors that report the position of the car on the road and possible obstacles. Therefore, the driver can simply press a button and relax: the car itself will keep within its lane at a safe distance from other road users. True, the system is still quite crude, so you should not seriously rely on it.<\/p>\n\n

Interactive control<\/h3>\n\n

Inside the Tesla, there is a huge 17-inch touchscreen. With its help, you can get all the information about the various systems of an electric vehicle and control their work. Also, the screen can be used as a regular tablet with Internet access.<\/p>\n\n

Battery<\/h3>\n\n

The designers came up with a special design of the flat battery, which was called “skateboard”. It consists of more than 7000 small cells, very similar to conventional AA batteries. They are placed in an incredibly convoluted pattern that is a Tesla Motors secret. As a result, the battery with a capacity of 85 kW * h fit into a body only 15 cm thick.It allowed installing the battery under the rear seats of the electric car.<\/p>\n\n

Silent operation of an electric car: an unexpected drawback<\/h2>\n\n

At the dawn of the birth of electric vehicles, the noiselessness of their work was positioned as one of the main advantages. Experience has shown that this is far from the case. Silently sneaking electric cars caused a large number of accidents – pedestrians simply did not hear the approaching car. To solve this problem, the developers came up with the idea of building a sound warning system into cars.<\/p>\n\n

Finding the right sound is a difficult task that not only engineers but also psychologists work on. The sound of an electric car should stand out well against the background of normal city noise and at the same time not annoy pedestrians. For example, a futuristic Canto sound was generated for the Nissan Leaf by experts from Hollywood, which is reminiscent of the cult Blade Runner movie.<\/p>\n\n
