One of the disadvantages of electric vehicles is that lacks speed and power, but sources say that the electrical kits can offer the speed of between 70 and 75 kilometers per hour. Another disadvantage that we face is to reload the batteries. In some electrical equipment, the battery must be cumbersome in every 20 to 40 miles, depending on the driving habits and the quality of the battery. This type of driving is fit only for the units of city and is not ideal for long trips.

To drive in the city, this would be ideal. However, for long journeys in the road, this would not be ideally long journeys. The conversion of a car in an electric is not a matter cheaper, can cost a lot. Thinking in practice, when comparing the costs involved the use of a kit of electric vehicle, it is always better opt for the car regularly, especially if they do a lot of lead on the road. But again, if you are looking for a car purely ecological side to side of the city of driving then you have the car. In India currently Maini REVA shines away, but now there are companies that are planning to launch electric cars.

For its part, the mark of cars Toyota also provide electric vehicles and precisely this launch its prototype model FT-EV II, which is still in concept. The people of Toyota refers to him as theca of the future, this is also equipped with a lithium ion battery that provides a range of at least 90 kilometers of movement when this is charged to the maximum in addition to a maximum speed of 100 kilometers per hour, a figure very optimal for urban life. On the other hand, it is reported that is also designed to provide basic functions of communication, giving in addition to a navigation system and information required by the pilot the possibility of download music. It should be noted its aesthetic very modern film.

Finally it is worth mentioning the auto Chevrolet Volt 2010. Recharging after three hours and maintains a power of up to 150 CV. This sedan five doors and front-drive leads the term car electric a step forward.

But back to the principle, although it could define as electric car to anyone whose propulsion recourse to the electric power. There are various possibilities in the given these circumstances by which, considering the current technology of the vast majority of cars, try decrypt the electric vehicle starting our explanation in the current situation and making a journey to the electric car pure. On the basis of heading the vehicles more traditional, the existence of a battery in the same only involves the use of electric power to move the different accessories of the car, but not to drive. With a voltage usual 12 volts, this type of battery is low voltage and does not cooperate in any way to the movement of the vehicle.

During the season of 2009 Formula One World became famous a system called KERS (Kinetic Energy Recovery System or recovery system of kinetic energy). Available in different configurations, the idea of the same was to recover the kinetic energy to, after being transformed into electrical energy, use it to increase the capacity to propel the vehicle. This same concept is used in some cars of street but at a level much lower, and with certain differences. Thus, for example, electric power accumulated can help the functioning of increasingly system start&stop, which allows shut down completely combustion engine during a stop and start automatically once the pedal is pressed the accelerator. In these cases, the electricity is used, especially, to reduce consumption, because it is of systems that do not drive directly to the car but to improve the efficiency of the set. The vehicles that have these and other similar systems fall within the concept of microhybrid.

A step beyond are cars that have internal combustion engines (diesel, gasoline or other) which, combined with electric motors, driving the vehicle. We talk about then of hybrids themselves. Although it is clear that the energy moves to the vehicle can be a combination between internal-combustion engine and electric (one or several), there are also certain nuances. In most cases the electricity fails to help the propulsion once batteries have reached a certain level of cargo, leaving then that is the combustion engine which accounts for all of the force of propulsion. There hybrid vehicles in series or in parallel. The hybrids in series can move only with the electric motor or a combination of electricity and combustion engine. When we talk about a hybrid in parallel the strength of the electric motor is used only as an aid to the combustion engine, and may not the vehicle to get around only through electricity.
The use of systems of energy recovery as the already KERS -although much less dramatic- are common in hybrid models. In this case accumulates energy in specific batteries, other than the usual 12 volts, which will, in turn the responsible for providing energy to the/electric motors. In the current hybrids known more autonomy of the vehicle in electric mode (if it is a hybrid in parallel) is very limited, being in the environment of the two or three kilometers. We therefore also speaking of a type of vehicle in which the contribution electric is very low and is used primarily to reduce the consumptions end in certain circumstances, being especially useful in the city but much less efficient in movement by road.

Another of the characteristics that distinguish between different types of hybrids is the amount of cargo that can accumulate their specific batteries and the way in which they are recharged. As we have already discussed, the vast majority of hybrids currently available on the market resort to recovery systems of energy to recharge its batteries, may create energy in situations such as braking, decelerations or declines. The amount of energy that can accumulate in this way is limited and that is why it is their autonomy. With batteries more efficient (usually lithium-ion) can create hybrids for greater autonomy and also with the possibility of being burdened by a plug connected to the electricity network. In the latter case could speak already of hybrids of autonomy extended in which the vehicle has a range of between 50 and 60 kilometers using only electric power for, using subsequently the combustion engine, able to continue doing a good number of miles.
And in the final stage find electric vehicles cigars. In them the propulsion is always carried out in electric mode, remain the only that can boast of zero emissions into the atmosphere. With the batteries of higher performance, electric vehicles pure stored energy in them and are propelled by one or more electric motors.
