Compare the advantages and disadvantages of various electric cars

The advantages of electric cars

1, environmental protection, electric vehicles use power battery pack and motor drive power, it won't produce waste at work, no exhaust gas pollution, the environmental protection and clean the air is very good, can say is almost "zero pollution".

2, low noise, electric cars don't like driving car noises, it generated noise is negligible.

3, economic: electric cars use cost is low, only about one 5 of the petrol car. And high energy conversion efficiency, recycling braking, hill and energy at the same time, improve the efficiency of energy utilization. Cheap "valley electricity at night using the grid", bring down the grid peak to valley difference effect.

4, easy maintenance, electric cars and by motor battery which drive, without the traditional engine cumbersome maintenance projects, such as: oil change, filter, belt, etc. Electric cars need to check the battery components such as motor on a regular basis.

5, policy: a lottery a success rate is high, the high subsidies, shall be exempted from tax and other policies on the advantages are more obvious.

The electric car faults

1, short range: general domestic pure electric vehicle range is 150 km or so more, plus the weather, road conditions, batteries and other factors, the actual range is 100 km. Drive needs a good planning route before going out, it is more troublesome. As one of the most common Baic E150EV electric vehicle as an example, the factory calibration of the range of 150 kilometers, through practical experience, it is about 120 kilometers, the average range in if you use less than 20% of the battery capacity, so still a lot of influence on the service life of the battery. As everybody knows, drive from downtown Beijing Pinggu has about 60 km, 120 km to and fro, electric cars, if driving is a very dangerous thing, one thousand went wrong or night out an exit, then you will have. Visible, even a day at the Beijing suburbs are unable to meet us, then bought electric vehicles are basically farewell road trip or a long travel on your behalf.

2, long charging time: normal charging time of 8 hours, quick charge also will take 1 to 2 hours.

3, imperfect supporting facilities: the current domestic charging stations such as rare, hard to find its trace. Need a long time construction of supporting infrastructure.

The advantages and disadvantages of four types of new energy vehicles

New energy vehicles probably can be divided into four categories: have a pure electric vehicles, electric vehicles, plug-in hybrid, and ordinary hybrid vehicles. Then let me to analyze the advantages and disadvantages of these four kinds of models and need to be aware of when buying things.

Pure electric vehicles

Now the most mainstream of new energy vehicles is the pure electric vehicles, by the power converter is needed to give the vehicle battery, and then drive motor drive.

's longest range is only more than 400 kilometers, although look range and regular gasoline car filled up at a tank's life course. But charging and charging pile is not as common as gas stations, and charging time than to fill it up with a tank of gas and much longer. So even in the case of battery condition had better go out of also can't more than 200 kilometers in radius, otherwise can recharge the push back home.

Conclusion: even now the longest range of pure electric vehicles can only do, so when you choose the pure electric vehicles to take into account your usual biggest car mileage and whether need to run a long distance. A lot of pure electric vehicles can only life more than 100 kilometers, is a most to work instead of walking tool. Now pure electric vehicle technology is not perfect enough, and charging is more difficult, although the pure electric vehicles can achieve zero emissions of air pollution management have certain help, and travel cost is very low. In Shanghai, Beijing and the limited number of car city of pure electric vehicles can be more easily acquired index, but if you are buying the first car editor still advise you to carefully choose the pure electric vehicles.

The official range: 130 km to 160 km

Increased program electric vehicles

Electric cars not only have an electric motor, increase program also has a traditional internal combustion engine, internal combustion engine is not only involved in the motion of the vehicle, but responsible for battery charging motor. This design not only can charge the battery through charging pile retaining the advantages of pure electric vehicles, and can reduce the battery without electricity thoroughly embarrassed.

Biggest life journey can be up to 320 km, hundreds of kilometers of fuel consumption was only 4-5 l, is still very fuel-efficient, but selling price and cost than pure electric vehicles.

Conclusion: increase program electric maximum retained the efficiency of pure electric vehicles, battery unused before it is common pure electric vehicles. But there is a gasoline engine to recharge the battery, out of town in the heart will be steadfast many, after all gas stations are much more better than charging pile to find, won't appear cart embarrassing, generally increase the program electric car than pure electric vehicles in terms of practicality.

Plug-in hybrid vehicles

Plug-in hybrid cars also has an electric motor and a conventional internal combustion engine, and increase the program models, plug-in hybrid vehicles with internal combustion engine as the main source of power, auxiliary drive motor model to run. Motor can jointly with the engine output power, the battery runs out before has very abundant power. But the engine didn't help the battery, the battery still need power supply and charging pile.

Now that is called a plug-in hybrid, so to ensure the 60 kilometers every day life, every day to find the local charge is required.

Conclusion: plug-in hybrid cars in nature or internal combustion engine vehicles, just joined the motor and battery, will give it a pure electric mode or low-speed electric burn oil drive mode at a high speed. Such a design more low carbon environmental protection, and can also have enough power, if you can charge every day, even can have a pure electric vehicles in the economy. And in cities such as Beijing and Shanghai can also get a car first. But if without charging right place, then the plug-in hybrid vehicle with ordinary engine drives the car, and will have to load heavy batteries and extra generator, some do more harm than good.

The traditional hybrid

The traditional hybrid models don't need to charge the pile and charging power supply. By the engine battery self-sufficiency, brake kinetic energy recovery when charging. Drive mode and plug-in hybrid vehicles, low speed when using pure electric mode to avoid the gasoline engine the oil phase, high speed is the use of engine and avoid the problem of insufficient power high speed electric motor, and also to be able to recharge the battery.

Conclusion: the traditional mode of hybrid models while still in the traditional internal combustion engine to drive mode, but is good to avoid the shortcomings of traditional internal combustion engine, to the best use of each fuel. Don't like the plug-in hybrid models that need the power converter for charging, under any condition, can maintain the most fuel efficient state. But the traditional mode of hybrid models are not in the national directory of new energy vehicles, so in need of a lottery cities also need like ordinary car to participate in a lottery. Traditional hybrid technology due to come out earlier, technology is mature, so the ownership is larger, price is relatively cheap and maintenance more convenient.
