Today we will discuss about the Benefits of Hybrid Cars. Internal combustion engines have an interesting feature. Their efficiency depends strongly on the mode of operation. They show high efficiency in a strictly defined mode, that is, at certain revolutions, under a certain load, under the condition of operating in a stationary mode (without changing the number of revolutions per minute). In other modes, their efficiency can be less at times. The engine in an ordinary car works exactly in opposite conditions. Turnovers are constantly changing, the load is also unstable.
A hybrid engine solves this problem. It drives the wheels from the batteries by means of electric motors. The efficiency of the battery system and electric motors also depends on the load and speed, but this difference can be 10 – 15%, not at times. And the internal combustion engine starts when the batteries are discharged, operates in a strictly calculated optimum mode, charges the batteries and turns off.
Movement in the urban cycle assumes constant acceleration and deceleration. When accelerating, we burn fuel. When braking, the brakes and the surrounding air are heated.
The hybrid engine also solves this problem. Although not all hybrids now have such a system, but the best companies have already implemented it. With smooth braking (releasing the accelerator pedal), the energy does not dissipate, but accelerates the rotors of the electric motors, so that they become electric generators and recharge the batteries. Of course, in case of emergency braking, good old shoes are used.
I note that DC motors can develop much more time than internal combustion engines of similar power. Electric motors are accelerated smoothly, without failures at certain speeds. So the hybrid car just jumps from the spot.
Benefits of the Hybrid Electric Cars
Economical exploitation is the main advantage of hybrids. To achieve it, it was necessary to find a balance, that is, to balance all the technical parameters of the car, but at the same time to preserve all the useful parameters of a conventional car; its power, speed, the ability to quickly disperse, and many other very important characteristics incorporated in modern cars. During braking, the kinetic energy of the movement is not wasted and the energy is accumulated by charging the flow. This allows less wear of the brake pads.
Reducing the consumption of carbon fuel, immediately affected the environmental cleanliness. The complete stopping of the work of engines in the places of congestion of cars on the roads of cities, and especially in traffic jams, is of the utmost importance. The use of batteries, much smaller capacity than in electric vehicles, has reduced the problem of recycling used batteries. The widespread use of hybrid vehicles in large vehicles, especially in public transport, will prevent atmospheric pollution in the city.
Good running characteristics
At the moment when a sharp increase in the traction load is necessary, both an electric motor and a normal engine are switched on simultaneously (and in some models an additional electric motor). This allows you to save on the installation of a less powerful internal combustion engine, running the main time in the most favorable mode for yourself. Such a uniform redistribution and accumulation of power, with the subsequent rapid use, allows the use of hybrid plants in sports cars and SUVs.
Time is the most valuable resource for a person. Elimination of half of the arrivals at gas stations, and even more such races, while driving around the city, frees the car owner some time for other large and important cases.
Conservation and reuse of energy
The main disadvantage of the engine on carbon fuel is the impossibility of returning energy back to the carbon fuel. Transport engineers have long tried to save the energy of motion during braking in order to reuse it. For example, special designs with a large flywheel were used. But only electric energy can be saved with the most minimal losses and the cheapest. Both storage batteries and special capacitors are used as a storage device.
Electric vehicles still have one big drawback the need to charge the battery. The process is long, and requires some specially equipped charging point. Thus, it becomes unsuitable for long and long trips. But technologies have already been developed that allow charging lithium-ion batteries with electrodes from nanomaterials to 80% capacity in 5-15 minutes.
Maximum of auxiliary systems
Also, hybrid cars have a number of design solutions and a maximum of auxiliary systems for high efficiency and reducing harmful emissions; start-stop system, timing change, EGR system, heating of the coolant by exhaust gases, etc.
There is no mandatory charging
Hybrid does not require mandatory charging from the mains and refueled with simple gasoline. After burning the fuel, some of the energy is stored in the battery, from which the electric motor is driven. An additional source of power for charging the battery is the regeneration of the braking, that is, the conversion of the kinetic energy of the moving car into electricity.
Among the advantages of economical hybrids, you can also highlight the method of refueling. Despite the combined drive method, hybrids are fueled only by combustible fuel, since the drives for the electric drive are charged during the operation of the internal combustion engine.
Due to the fact that hybrid cars have not yet received a large distribution from a mass user, it remains difficult to find qualified specialists who are able to carry out repairs. And this is also a disadvantage of hybrids.
