Current situation and future prospects for electric cars
Electric cars are eco-friendly to the low level of environmental pollution, because they are not used fuel, lubricating oil, coolant and have no emissions, but the technology must replace the polluting sources of electricity with alternative sources clean.
Beyond this premise the electric cars have the following positive aspects:
– cleaning, because don’t emit harmful elements and don’t burn oxygen of the air;
– noiselessness, without noise and vibrations, for a really comfortable driving;
– good sustainability. It may improve with technological research to charge the batteries with solar panels;
– reliability, because the electric motor has low maintenance costs, as it has few moving parts, then with less likely to breakages;
– economy, because the cost of electricity is much lower than the cost of conventional fuels and you don’t pay car tax and London congestion charge;
– in some cities there are free parks with electric outlets for recharge batteries..
The use of electric cars has, at the time, some drawbacks:
– poor autonomy and poor performance at low temperatures by certain types of batteries;
– overall there are too few electric outlets to recharge batteries;
– the charging times are again very high. Most public stations and the workplace takes 6-8 hours to fully charge the batteries, the control units that allow fast charging in 2-3 hours or rapid in ½ hour, are still very scarce and not everyone has the garage to recharge the batteries in home, overnight;
– the lack of noise is a danger to pedestrians, whereby we should equip electric vehicles of automatic sound devices.
-the purchase prices of electric cars are again too high and the government incentives are still too low.
The greatest limitation of the electric cars is the battery, short-lived, expensive and slow to load. The research is focusing on the graphene, a material to build super-capacitors to store electrical energy quickly, then releasing very slowly.
