Advantages and Disadvantages of EVs
The most obvious advantage of electric car batteries is that they don't proce the pollution associated with internal combustion engines. However, they still have environmental costs. The electricity used to recharge EV batteries has to come from somewhere, and right now, most electricity is generated by burning fossil fuels. Of course, this proces pollution. But how does the pollution proced by burning fossil fuels to recharge electric car batteries compare to the pollution proced by internal combustion engines? According to the Electric Vehicle Association of Canada, or EVAC, even EVs recharged from coal-powered electric generators cut carbon emission roughly in half. EVs recharged from cleaner forms of electrical power generation, such as hydropower and nuclear plants, can rece carbon emissions to less than one percent of those currently proced by internal combustion engines. So, even in the worst case scenario, cars operated by EV batteries are cleaner than gas-powered cars.
Another important advantage of battery-powered motors over gas-powered engines is the lower cost of the fuel -- that is, electricity for EVs and gas for the internal combustion engines. The United States Department of Energy has calculated that a typical EV can run for 43 miles on a dollar's worth of electricity. Only a substantial drop in the cost of gasoline could give gas-powered cars anywhere near such a low cost per mile.
Yet another advantage of these rechargeable batteries is that they recycle well. Almost 100 percent of these batteries can be recycled, which keeps old batteries from becoming a disposal problem.
The major disadvantage of battery-powered cars, as we mentioned in the last section, is the time required to recharge the batteries. With lithium-ion battery technology, a fully charged EV can travel a distance comparable to an internal combustion engine vehicle with a full tank of gas, but it still needs to be placed on a recharger at the end of that time. At present, this means a drained EV will be out of service for several hours before it's fully recharged. Of course, this is a serious disadvantage. In the future, faster recharging technology may become available, but in the near term, electric cars won't be the vehicles of choice for long trips. Even so, most driving is done relatively close to home and for this reason, battery power will serve as well as gasoline power. A possible solution to the recharging situation may be battery-replacement stations, where instead of recharging your EV you can simply swap your drained battery for a fully charged one. This system would allow batteries to be recharged outside of vehicles and would greatly rece the amount of time required to get an EV up and running again after its battery is fully discharged.
Another disadvantage of electric car batteries is their weight. Because they need to do more than traditional car batteries, electric car batteries need to be linked together into arrays, or battery packs, to provide additional power. These collections of batteries are heavy. The lithium-ion battery pack in a Tesla Roadster weighs about 1,000 pounds (453.6 kg). That's a lot of weight to carry and it can greatly rece the car's range. However, the designers of the Roadster have offset this battery weight with a light frame and body panels. The entire car only weighs 2,690 pounds (1220.2 kg) -- not terribly heavy when you consider that more than a third of that weight is battery.
Given the importance of the battery to an electric car, you might wonder what will happen as that battery grows older. How long will it be able to power the car? And when it finally dies, can it be replaced or is it simply more economical to buy a new car? Read on to find out.

Second, the direction of development of new energy vehicles
Now for the new energy vehicles have a precise definition , refers to the use of unconventional vehicle fuel as a power source ( or the use of conventional vehicle fuels , the use of new -vehicle power unit ) , power control and drive advanced technologies integrated vehicle form the principle of advanced technology , with new technology, new structure of the car. New energy vehicles including hybrid vehicles, pure electric vehicles (BEV, including solar car ) , fuel cell electric vehicle (FCEV), hydrogen engine vehicles, other new energy sources ( such as high energy storage devices , dimethyl ether )
Cars. The following describes the following:
A hybrid electric vehicle
Hybrid electric vehicles use an internal combustion engine and a motor as power , the power source because it has no need to store large amounts of power in the energy storage device , an electric vehicle which overcomes the disadvantages of the short distance traveled , fuel economy and significantly better than conventional vehicles. Saving a mainstream electric car market of non-renewable energy sources, while greatly recing exhaust emissions , is present. However, the two systems will be installed on a system originally installed only cars, not only increased the weight of the car itself , but also increases the overall process control requirements. Thus the complex structure of the hybrid vehicle control high technical requirements, the corresponding costs and the price is higher .
In addition, it is used in the conventional internal combustion engine , which consumes non-renewable energy is inevitable, in improving energy efficiency and environmental protection performance was unsatisfactory.
2 , pure electric vehicles
Pure electric vehicle is a motor fuel engine instead of using the motor as a power , electrochemical batteries as energy storage unit , with no dependence on oil , no noise and vibration , operating performance, high efficiency and outstanding advantages . Electric drive has the advantage of not using fuel , zero-emission and low noise ; simultaneously by using a single electric energy , electric control system greatly simplified compared to hybrid electric vehicles , not only reces the cost of part of the price , but also to compensate for the battery. However, the electrochemical battery energy density and power density is relatively small, low enrance , pure electric vehicles currently used only for tourism and other short-haul travel . Although the recent development of high-performance batteries , such as lithium-ion batteries was a great success , but its high cost , making further promote pure electric vehicles there is a very great difficulties . FIG 2 is a configuration diagram of a motor pure .
3 , fuel cell electric vehicles
Fuel cell -powered electric vehicles with motors , fuel cells as an energy conversion device , the use of hydrogen as a fuel. Difficulties in the development of fuel cell vehicles is the storage of hydrogen fuel , fuel cell size and high proction costs , developing high-performance proton exchange membrane and the complex control system, the use of fuel cells as a power source for electric vehicles called fuel cell electric car FCE (Fuel Cell Electric Vehicle), the first FCEV fuel cell buses FCEB (Fuel Cell Electric Bus). Quality early FCEV fuel cell itself and its ancillary equipment heavy , bulky, occupy a large part of the bus loading space , almost no space for passengers , to bring the total layout FCEV great difficulties . Compared with the traditional internal combustion engine vehicles , FCEV not through the process of heat engine , without limitation Carnot cycle , with the advantages of high energy conversion efficiency and environmental friendliness unparalleled internal combustion engine vehicles , while still maintaining the traditional internal combustion engine vehicle speed, long-distance running safety , comfort, and other properties, is considered the preferred 21st century clean, efficient transport. Domestic and foreign experts believe that fuel cell technology will become the core of the automotive instry in the 21st century .
