The three main problems for the electric vehicle are about the generation of electricity, recharging station, and the battery.
For the generation of electricity, the increase in electric vehicles will also increase the production of electricity from thermal and nuclear power plants, impact on the environment will be negative. The main positive impact of electric cars is friendly to the environment. However, a lower cost of electricity generation like nuclear power plants may have an opposite idea to electric car. Therefore, we can solve the problem by developing the electric vehicle and the renewable energy at the same time, for supporting the electricity supply to electric vehicle in an environment friendly method.
Concerning about the recharging station, due to the common use of electric vehicles in the future, many recharging station and recharging park are needed. It would take a long time as ten to twelve hours for fully charge of an electric vehicle, however, a normal car by using diesel are only needed to refill within ten minutes. We cannot imagine how many cars are able to charging at the same time. Therefore, government can only solve this problem by a well land planning, build a lots of recharging station in a suitable place and suitable distance. For Portugal, the government commits to a network of 1,300 recharging stations. Large amounts of recharging station are needed to develop electric car.
For the battery, the recharging battery is the most important part of an electric vehicle. Engineers should make the battery life as long as possible. Due to the difficulty of recycling the battery, the more waste of battery the more unfriendly to the environment. Therefore, one hand the engineering should increase the battery life; the other hand should find the way to recycle the electric car’s battery as soon as possible.
