Disadvantages and problems
Battery charging and price. Batteries of more than 400 km of autonomy are very expensive and are recharged in about 9 hours without reducing capacity. To avoid this problem would require changing downloaded by other immediately charged batteries, so that when refueling at a service station from entering the vehicle without power and nearly out of there totally or partially loaded a few minutes later. For this battery should fit snugly so they can be moved quickly and that this could be done both as fractional totally.
Some continue to pollute, because in some cases the electricity used to recharge the batteries is produced by polluting raw materials such as coal. In Spain, for example, the electricity used for batteries involves emissions of carbon dioxide 0.276 kg / KWeh generated.
Less autonomy than a conventional car because you need frequent recharging.
The strong initial purchase cost. In some cases the price of an electric car is three times that of a conventional car. Example: A Toyota Corolla, Toyota high-end, can cost around 17,000 euros with the basics, an electric vehicle like the THINK City at the market reaches 30,114 euros. This could be solved if manufacturers decide as it has already checked with hybrid vehicles that they tend to drop in price and gain market share quickly.


Advantages 

Do not produce air pollution.
They do not produce noise pollution.
Its use eliminates the need for fuel oil and thus saves a limited raw material and can be devoted to other matters also needed.
Maintenance and cost of "fuel" is much lower than a conventional one. The Tesla Model S, for example, spends $ 700 of electricity per year; Porsche Panamera Turbo fuel spends $ 3,400 a year.
Greater efficiency and torque from 0 rpm and the total absence of gears, which results in better throttle response.
In sports, the use of distributed power to the wheels and engine torque control each provides greater cornering stability, and hence safety.
According Laverón Francisco, Miguel Angel Munoz and Gonzalo Sáenz de Miera, two economists and an engineer from the company Iberdrola, a car gets an efficiency of 77% if the electricity comes from renewable sources, while 42% of electric power if appropriate based in natural gas. Furthermore, these authors argue that an electric car can travel nearly double the kilometers that one of gasolina.1
