GREEN CARS: MODELS, TECHNOLOGIES AND MORE
Electric cars, hydrogen or hybrid models amazing. We tell you how these technologies obliterate looking pollution in your city.
The green cars are the new trend in the motor world. Basically we talk about cars that reduce or eliminate emissions of CO2 (carbon dioxide) into the atmosphere, so as to reduce global pollution, keep cities cleaner and not cause damage to the ozone layer. There are several technologies that are being used, some already consolidated as electric cars and other more novice how the use of hydrogen . Each has its strengths, weaknesses and recommended uses, so that you may know better than ask yourself before investing in any of these cars. Let’s begin:
They combine a conventional engine with another power , hence its name. The trick to reduce fuel consumption is to use the electric motor in short sections or to assist conventional operating in the best conditions.
Perhaps the most may know is the Toyota Pirus , which can propel electricity alone while going at low speed (less than 60 km / h). Other models such as the Civic Hybrid, are simpler and the electric motor only dedicated to assist the conventional, eg starting or turning it off when braking. The fact is that all gasoline consumption decreases, some below 4 l/100 km.
Now you ask … How do you recharge the batteries of the electric motor? It depends on the model. In hybrids I mentioned before is recharged while using the conventional with the energy that would otherwise be wasted, as the braking. However, some new models can be plugged directly into a wall charger, so-called ” hybrid plug-in ”
In this group we have the Opel Ampera and the Chevrolet Volt, among others. The magic is that with a load of six hours can travel between 50 and 100km, which makes them ideal for use in day to day city. When the battery is just passed to the motor fuel used to move the vehicle, or better yet, to charge the battery while still using. Here we describe in detail.
100% Electric Cars
These cars completely eliminate the gasoline engine and an electric one replace it with large batteries. This limits their autonomy that stays between 100-200 km on a single charge, but are super cheap to make: to walk 100 miles just spent € 1.5 into electricity. To upload you can do at home in about 9 hours or in some specialized loading points (something few outside the major cities) in 30 minutes. This however is time consuming, so they are recommended primarily for use in the city. Examples include the Citroen C-Zero and the Nissan Leaf among several others that are sold in Spain . Watch their prices: they approach the 30,000 €, especially how costly are the batteries.
The latest innovation, is based on the use of a generator called “fuel cell”, which combines hydrogen and oxygen to produce electricity , so that, ultimately, are electric. The main difference is that hydrogen charging in a car is much faster than plugging into a charger (takes 5 minutes) and the autonomy that rises to 500km. The only waste product is water vapor, so that no contaminating directly. They are the main choice to replace gasoline , but is faced with problems such as the high price of compressed hydrogen and the few existing load centers. Moreover, its bulky price: can go over 100,000 €. There are already some available, although almost incomparable as the Hyundai ix35. Several companies are working on this technology, so it will come with everything in the coming years.
